The Sprinkler Nerd Show

For immediate release—breaking news, kind of. In this solo episode of The Sprinkler Nerd Show, Andy dives into what seems like a revolutionary product: a mechanical rain sensor that requires no batteries, no Wi-Fi, no firmware updates—just pure, functional design. It shuts off irrigation during rainfall and turns it back on when conditions dry out, all thanks to hygroscopic discs that expand and contract to trigger a simple switch. This device sounds like the newest drop in water-saving technology—until Andy reveals the twist: it's not new at all. In fact, it's based on US Patent 3,808,385, filed in 1972 and granted in 1974. That's over 50 years ago. And the core concept of the mechanical rain sensor hasn't changed since. Andy breaks down how the device works, why it's still effective today, and what it says about the pace of innovation in the irrigation industry. He challenges contractors and tech developers alike to ask the big question: why are we still using 1970s technology in 2025? Could we create a smarter, data-driven rain sensor that actually logs rainfall events, provides historical context, and informs better irrigation decisions? If so—why hasn't anyone built it yet? Key Highlights: Breakdown of how the moisture-responsive switch actuator works Benefits for contractors: simplicity, reliability, zero maintenance Installation and adjustment tips Why the current state of rain sensors is a wake-up call A challenge to the industry: let's rethink how we track rain and respond to it Andy closes the episode with a call to action for all Sprinkler Nerds: always ask why. Why things work the way they do, why they've stayed the same—and how we can make them better.

Hello, friends! I wanted to take a moment to share a quick update on what's happening this week. I'll be traveling to Calgary and Edmonton, Canada, for the SiteOne Landscape Supply One Stop events. On Tuesday, I'll be at the Calgary event, and then on Thursday, I'll attend the Edmonton event. After that, I'll head back to the airport Thursday night and fly home on Friday. I had to adjust my travel plans a bit, departing from Grand Rapids instead of my usual airport because, upon my return, I'll be meeting up with my daughter. We're headed straight to a volleyball tournament in LaPorte, Indiana—an exciting way to wrap up the week! If you're in the Calgary or Edmonton area, I'd love for you to stop by the SiteOne events. Please make it a point to say hello! It's always a pleasure meeting industry professionals, and I'd love to hear what's happening in your world. An Update on Project Harmony For those of you following my journey to bring affordable wireless soil moisture sensors to market, I wanted to share some exciting news. We've successfully deployed a few hundred beta sensors—yes, handcrafted by yours truly! The beta launch has been a huge success, and if you'd like to learn more about Project Harmony, visit harmonyanalytica.com. If you're interested in participating in the beta program, you can receive a sensor and Wi-Fi hub for just $100. Simply visit harmonyanalytica.com/beta to sign up. I'm also looking for industry professionals who want to integrate wireless sensors into their business. I'm even considering launching a private group for beta users. In this group, I'd share everything I've learned on this journey, and together, we could build the next generation of water analytics and landscape insights. Behind the Scenes of Sensor Development What's fascinating about bringing sensors to market is that the biggest challenge hasn't been the measurements—it's been the manufacturing process. I've learned so much about 3D printing, epoxies, potting materials, and even things like glue types and vapor smoothing chambers. Right now, it's a 2-to-1 process—for every two sensors I manufacture, only one makes it to the field. Many work perfectly but have small cosmetic blemishes, making them unsellable based on current standards. This is one idea I'm considering for the beta group: offering these fully functional but slightly imperfect devices at no charge for testing and learning. If you're curious about how wireless sensors work, how they can add value to your business, and how we can revolutionize the industry together, I'd love to connect with you. Let's create the next wave of innovation outside of the traditional wholesale landscape manufacturers. That's my week ahead! I look forward to meeting any of you who are in Western Canada at the Calgary or Edmonton SiteOne One Stop events. Stop by and say hi—I'd love to connect. Thanks for listening, and let's keep innovating!

In this episode, we uncover a remarkable story hidden in plain sight: Ronald Wayne, the often-overlooked third co-founder of Apple. While Steve Jobs and Steve Wozniak achieved legendary status, Wayne's name is hardly mentioned in the tech world—even though he helped draft Apple's original partnership agreement and designed its first logo. After just twelve days, he chose to walk away from his 10% stake in Apple for a mere $800, a decision that would come to symbolize both the enormity of risk and the unpredictability of life. I share how my son, Drew, and I stumbled upon Wayne at an afterparty during the Consumer Electronics Show (CES). This unexpected meeting led to an eye-opening conversation about everything from historical shifts in monetary policy to Wayne's current passion for investing in silver. Drawing on Adam Smith's Wealth of Nations, he argues that today's fiat currencies are on shaky ground and sees silver as a tangible asset that may protect wealth when paper money loses its luster. Throughout our chat, Wayne's calm conviction and life experiences shine through. He exemplifies the power of informed decision-making, a willingness to pivot when necessary, and an unwavering commitment to charting one's own course. Despite leaving behind what could have been billions, he found fulfillment in engineering pursuits and personal independence. Tune in to hear my reflections on Wayne's journey and the lessons we can all draw from his story. If you're curious about his detailed thoughts on the future of money, stick around for the recorded audio of our conversation with Ronald Wayne himself. It may be a bit difficult to hear at times, but it's worth the listen if you want to glean insights from one of Apple's most intriguing figures.

Here because I don't have time to record a full episode with brand new content, but it did get me thinking about just soil moisture sensing and field capacity and understanding the numbers, and you're gonna hear all that on this episode, this replay episode. But I wanted to share a new concept that actually it's not completely new, but a concept that I have running, in ex in an experiment right now. And that is a concept of taking multiple soil moisture sensors, let's say, within one zone, and averaging them together to creating new soil moisture or that you might think of as a synthetic value. So there's always the angel question of, you know, how is this one spot where the soil moisture sensor is buried. How how is that relative to the rest of either the site or the zone I'm not gonna get into all of those details. We'll save this for another episode. And and the and that is that is a valid question. And the only real way around causing a mistake is to actually just locate the sensor in in a really good area. But then what would happen? What would it look like if instead of putting one soil moisture sensor in a zone? Or one soil moisture sensor in every zone, we put 3 soil moisture sensors in one zone and use that one zone as the baseline zone for the rest of the site. And it's not actually possible today to do this with any control system. Even a baseline control system. You cannot install you can install 3 soil moisture sensors in a zone, but they're all going to be independent, and only one of them can actually control the zone. But what if you could take those 3 soil moisture sensors buried in the one zone, average them together to create a new synthetic, you know, synthetic value and use that average value to control the zone. What would that look like? That can't be done today, but I'm doing it. I'm actually I'm actually running this experiment. We have a a project that has I should know this number off the top of my head, but I don't. Let's say if it has 8, it has 8 soil moisture sensors. And each soil moisture sensor is actually buried in in its own zone, 8 slow moisture sensors, 8 zones, but then I'm taking all of those 8 slow moisture sensors averaging them together and creating a new value that says here's the average soil moisture across the entire site. And what's interesting about that is, well, first, it it hasn't been done before. But second, it might make up for potential errors in location, formity, etcetera, etcetera, if multiple sensors are installed within one zone average together to create a new value So that's just one experiment that I'm running right now. It's going really well. And, maybe maybe a manufacturer that might be listed into this podcast, we'll take that into consideration as they develop the platform. And, we'll just we'll just see how it goes. But Wanted to give a special shout out to Juanita. Thank you for being an active podcast listener. Appreciate hearing from you. And, with your recommendation, I'm gonna replay the episode from April, I think April 28th 2023 called field capacity, my ass. It is great content. I highly encourage you to listen to the entire episode. And if you don't have time today, bookmark it, listen to it again, and I'm, excited to talk about field capacity more in the future because it's more relevant than it ever has been. So thank you so much for listening. Appreciate all of you. And, we'll just roll the intro here and get right into the episode on field capacity. Okay. So in order to understand field capacity and talk about field I first think we should define field capacity. Field capacity refers to the maximum amount of water that a soil can hold against the force of gravity. Alright? It's kind of the point at which the soil is fully absorbed I won't say saturated, fully absorbed with water, and then the excess water has drained away. K? After that excess water has drained away. That's field capacity. At field capacity, the soil is sort of holding as much water as it possibly can and any additional that we add to the soil will actually drain away due to that force of gravity. One great way to illustrate this, maybe this would create a mental picture in your mind, is to think taking a sponge in your kitchen sink. K? If the sink is full of water, you put the sponge into the water, you let the water soak into the sponge, fully, then you lift the sponge out of the sink, it starts to drip, drip, drip, drip, That's saturation as soon as the water stops dripping out of the sponge. That's field capacity. K? That's the point at which the water can hold the the the moisture after gravitational drainage. K. So the sponge is a great way to describe this. Great way to understand it. Great way for you to describe this to your customers, your clients. And seeing this on a graph is awesome as well. So typically, I like to see this on a graph. So historically, working with baseline controllers, I would pull up a soil moisture graph report. I would look at this, on the graph to understand the concept and teach people about it. Okay. So the way that it looks on the graph. And again, I think probably the best way for you to visualize this is that sponge because we can all picture a sponge dripping. Okay. And what that looks like on the graph is a spike. When when the soil is full of water and it is dripping, it it's not holding water. The water is actually draining out of that soil. So you see this spike wet. Boom. It spikes up. And it's draining quickly. Right? The water is dripping out of that sponge. So you get this needle tipped tall spike. And then as the drop start to slow down out of the sponge, that's that's kind of like a curve. It represents a curve, a dry down curve on the graph. And and that curve, which is sometimes called, like, the shoulder, the shoulder of that curve, that illustrates where field capacity is. Okay. And you can kinda measure it. So if we're looking this looking at this on a graph, you could take your cursor, you could hover over the line, and you could get a a numeric value for field capacity. Okay? So more on that in just a moment. The other way that we can describe field capacity instead of using that term, which is very scientific, but it's important for us to understand it, but the average person may not. So One way to describe another way to describe that to the average person is just using the term wet. Sounds easy, silly, but it but it's true. It's wet. Not too wet, not too dry, just right. It's the goldilocks of wet. It's perfectly wet, not too wet, not too dry, just right. It's the goldilocks of wet. K? And again, you can measure this. It's a scientific value. Feel capacity is scientific. How much you allow that to deplete is the art. You can you can deplete it as much or as little as your plants can sustain. But every soil has a field capacity value that can be measured. Alright? Let's go with another way to think about this. I'm gonna give you a few examples because maybe one will stick more than another, and these are just analogies that I've used over the years to help describe the concept. A third way to describe this is a lot like a percolation test. Okay. And a lot of landscapers know this and home builders understand this because if you have a well for your water supply. Actually, not a well. What am I saying? If you have a septic, system, A lot of wells also have septic systems versus city water. But if you have a septic system, typically, you have to do a percolation test to see how the water drains through that soil to see whether that soil can even house or hold a septic tank. Okay. So typically a percolation test, you dig a hole You fill it up with water. You watch it drain over time. And then that would determine if you would be allowed to get a permit from your town to put in the drain field. Okay. So the faster a soil drains the more sand there's going to be in the soil. And the slower it drains, the more clay we're gonna have in the soil. Or, like, based on that drainage rate, it can also describe, you know, kind of the compaction and the structure because the soil type is only one variable. Right? So if we say I have Sandy Lom, well, that does just because you have Sandy Lom or you think you have Sandy Lom or you sent your soil test to a lab, and they said you have sandy loam, it doesn't mean the soil actually behaves like you have sandy loam because there is compaction and there's structure in the soil. They can also affect how water moves through the soil. So What we're really chasing is that field capacity and we want to measure it and we measure it with the soil moisture sensor. Okay. Got it. Am I tracking with you, right? Picture the sponge, picture the, the perk test digging the hole, watching the water drain through the soil, we can measure those, measure the rate, and determine the soil type or actually more. We can determine that field capacity, which tells us about the soil type with the soil moisture sensor. Alright? So back to field capacity, feel capacity being perfectly wet, so Goldilocks wet. Alright? Now that's where things start to get really fun because if you can understand that concept, you can now understand how everything else about soil moisture works. It's all relative to field capacity. And I think this is where most current manufacturers, if not all current manufacturers have missed the mark. I'm gonna tell you why here in just a minute. Again, this is my opinion that most of them have missed the mark because they focus on volumetric soil moisture. They focus on the the data coming out, the actual reading of the soil at any moment, but one reading alone is not enough. Alright? So I'm gonna tell you what that means here in a minute. But I wanna also mention that typically, you know, engineers of soil moisture sensors, either just probes, control systems, engineers, know, like, what we're talking about. They know what this means. They know exactly what the readings are, how to set the sensors And from my personal experience, teaching and training on the subject matter for, god, it's crazy, almost 20 years. I know how to set the sensors, but I also know that the average knuckle dragger has no idea. And the first question that they always ask me, like, every time, how do I set the sensor? Andy, I put the sensor in. How do I set it? And so that's kinda what I wanted to talk to you about and provide you with some understanding of field capacity allowable depletion, permanent wilting point, all that shit can be so confusing that what we really wanna focus on is field capacity. Alright? And here's my tip If field capacity equals wet and wet equals full, k? Think of this like a tank, a tank of soil, full is 100%. So I like to take the volumetric moisture percentage and fine field capacity and set that to be full, because this makes the most sense to the average person. Is my soil full? Is my soil empty or where in between those values is it, but the actual volumetric soil moisture percentage doesn't matter so much after we understand field capacity. Because we're gonna set field capacity equal to 100% and then the tank size is going to be determined from that. Alright? And that's where I think most manufacturers miss the mark because they should set their calibration relative to field capacity and set a new tank size. Okay? So we're gonna get I mean, I'll give you a few examples here. In in a moment, but I want you to think about that concept. K? If field capacity is wet and wet is full in full must equal 100%. So field capacity equals 100%. K? Then we wanna know what is 50% full and what is empty. And that's really the skill that we should be thinking about, k, because if we take one reading, and which is actually something that people typically ask me. So let me give you let me give you that example. Oftentimes after someone installs a slow moisture sensor system, I would get a call. Right? And the the client says, Andy, you know, something like this. My moisture sensor is reading 28.5 percent What does that mean? How do I set the sensor? K. The question is, literally, most of the time, just like that. My moisture sensor is reading 28.5, or it's reading, it's reading some number, and they wanna know what does it mean? How do I set the sensor? And the funny thing is that my response is usually like, I have no freaking idea. K? How could how could I after with 20 years of slow moisture sensory experience, not know what 28.5% means. It's actually that I do know what it means. It means 28.5%. But I don't know what what that means in terms of wet or dry. K? Because I need more information. 28.5 percent or the the value that you're taking at any moment does not mean anything all by itself. It has to be made in relationship to field capacity. Right? Is that making sense? If we took a reading of 20 percent or 25 percent or 30 percent, one number all by itself doesn't mean anything. It only means something when compared to field capacity. And I made a couple notes here. Wanna give you an example. So this is one piece actually. I'm actually cheating here. Not reading word for word, but I I made some notes. So let's say for instance, we measure field capacity at 26%. Okay? If field capacity is 26%, And the client asks me, what does 28.5 percent mean? I I know right away, shit. That's higher than field capacity. That means your soil's freaking wet. Saturated and saturation because I can compare 28.5 percent to the known field capacity of 26. K? But maybe what if field capacity was 32? And they asked me, what does 28.5% mean? Then I know Well, it's not yet up to fuel capacity. Your tank is about, you know, 50% full or 60% full. You have to take the slow moisture sensor reading that you get, and you have to compare it to you have to compare it to field capacity. Alright? And every moisture sensor reading that is compared to field capacity has to be compared to field capacity on the very same sensor. You can't compare different sensors to each other because they're all installed in different environments. And how the sensor is installed in each environment could be different. Even if the soil type is the same, how the sensor is installed can affect the reading a bit, which means field capacity on one sensor might be 30. And in the same soil condition, you know, 100 yards away, it could be 32% based on how that sensor is installed. So you wanna compare the number that you're getting and feel capacity only on one sensor. Never compare 2 sensors to each other. Alright? So for this reason, what I usually recommend is that during installation, you pour a bucket of water over the sensor or any amount of water that's going to take to saturate the sensor, which means get it more wet then feel capacity. Get it kind of as wet as you can, you know, to a point. And then wait 24 hours. Kinda like doing that perk test. You wanna get it wet. Then you wanna let gravity take over and you wanna see what it does after 24 hours. You can come back to the site, take a reading, Or if your system is connected remotely, you can look at the graph. You wanna give it some time. You wanna, like, gravity do its thing. I don't like that sponge. You wanna pick that sponge up out of the sink. Let it stop dripping. So you wanna wet your soil, get it nice and wet, let gravity take over, and then you wanna take another reading. And that reading is field capacity. That's the right or downer. That's your baseline. That's field capacity. And everything else becomes relative to that number. If you take a reading in the future and it's higher, you know, your soils and saturation. If you take a reading in the future, and it's 50% lower, you know you're freaking dry. Okay. So the next question I usually get after we find field capacity, is how do I set the sensor? And this becomes the art. So I mentioned before that measuring field capacity is a science. Because you can actually measure it. The amount that you allow for depletion or dry down is the art, and there's only best practice And there's observation and there's knowledge of your plant material and the health of your plant material because all of those things can affect how dry and for how long can you maintain dry. But I have one general rule that I usually give to all clients as a starting point And that is 20 percent depletion, not 20 percentage points, right, not going from 30 down to 10, not 20 point 20 percentage points, but 20% of a number. And that is how you determine your tank size. You take field capacity, you subtract 20% of it, or you multiply it by 0.8 And that will give you your dry number. Alright? So let's look at a specific value. Let's pretend here today, that we measure fuel capacity and it's 30%. What would 20% depletion be? What would 20% dry be? What is that number? Well, I I typically do the math. 10% of 30 is 3. We'll double that to get to 20. That would be 66 percentage points. Field capacity was 30. 6 percentage points is our tank size, so 24 becomes the depletion. That's dry. We will let the soil go from 30 when it's wet down to 24 when it's dry, and then we'll fill it back up again. And I'm today, I'm not gonna be talking about how to automate we're just talking about the numbers itself. Right? So if you take your reading and it's 25%, you know, you're not dry yet because we just said 24 was dry. If you take a reading at 17, you know, you're way below your depletion point. Alright? And I use 20% as a starting point because you never wanna start too dry. You never want to you always wanna start a little bit conservative, see how it goes, then you could lower it a little bit, then you could lower it a little bit more. But the analogy of using 20 percent helps to describe how the tank size can be measured. So if we think about the field capacity number. And we think about taking 20% of it. So we started with 30%. We took 20% away. That was 6 that was 6 percentage points. Okay. And then turn on was 24. The type of soil that we're working with actually determines the size of the tank. So generally speaking, and this is kind of a, I guess we could call it a rule, clay soil holds more water. So when you measure field capacity in a clay soil, it's going to always be higher. So let's just say it's 33%. K? And the range is probably anywhere from 29 to, you know, 38% generally speaking. Clay soil holds more water, so field capacity is a bigger number. Sandy soil holds less water, so field capacity of sand will be lower. Right? Let's say field capacity of sand is 22%. And we're just assuming field capacity of clay is 33%. But if we use the general rule of 20 percent depletion, 20 percent of a bigger number is a bigger tank. Right? The more clay in the soil, the larger the tank size will be. The more sand in the soil, the smaller the tank size will be. Because 20% of a smaller number is a smaller number, 20% of a bigger number is a bigger number. So the smaller the tank, the more frequent it will need to be filled up. The larger the tank, the less frequent it will need to be filled up. Okay? It also means it'll take more take more water volume to fill it up, but the depletion will occur faster in soil and in clay I'm sorry. It's faster in sand than it will in clay. And I noticed this from my own sort of, growing up in Vermont, there is the soils very heavy clay. Lake Champlain used to cover a big portion of the state of Vermont and this the soil that was left at the bottom of the lake, you know, Eons ago has tons of clay in it. It holds a shit load of water. Mud season in Vermont, sucks. However, it's freaking green all the time because the soil doesn't dry out. Now, where I live, Now in Michigan, it's a sand dune. It's a big ass ant hill. The sand soil holds very little water dries out quickly, and you have to irrigate the hell out of it. K? The climate is actually very similar here in Michigan to where I grew up in Middlebury, Vermont, but the irrigation market in Michigan is huge. The irrigation market in Vermont is small. Vermont is green, Michigan is brown because of their native you know, soils. And again, I'm making some analogies here and some similarities. I'm not a scientist that knows any evidence of this other than from my own experience, but just sharing that with you because the soil type makes a difference. Another way to look at this is that if you had a 12 gallon gas tank, you need to fill up more often than if you had a 20 gallon tank. K? Now to fill up the 20 gallon tank takes more volume, takes more gallons, but you can go longer in between. K. So that's kind of some analogies of of, how this works. And that's really it. Like, that's all there is to it. K? Essentially, that's all there is to it. So it can be often it can be easy to often overthink this, overcomplicate this, and, like, totally miss the point. And the point is that you've got to find field capacity. Field capacity becomes like your baseline. Field capacity is everything. Field capacity is not my ass. Fuel capacity actually is everything, and everything becomes relevant to it. Right? It's that it's the known variable. You gotta find out for every single, sensor that you're that you're working with. And this is why in my opinion, it's actually impossible to input the soil type into the ET formula. We all know controllers, one of the inputs is soil type. Now it can get relatively close, but if 30 of us went out and We're in a class. We went outside and were asked to determine the soil type. We'd probably come up with 10 different answers. Not all thirty of us would pick the same soil type. So I think it's really fascinating that controllers ask the user to input the soil type, but the user cannot determine the soil type. It's it's like almost impossible to pick the soil type. Alright? Without sending it to a lab, of course, but even if you send it to a lab, the lab can't tell you if it's compacted and what the soil structure is. It can only tell you where it falls on the soil in the soil table, you know, which is better than nothing, or you could just put a damsel of moisture sensor in the ground and measure field capacity. Okay? So I guess just wrapping this up, I I believe soil sensors is the next revolution that we're gonna see in this industry. I mean, we are gonna see soil sensors hit hard, guys. And I think as professional irrigators, professional distributors, consultants, designers, landscapers, landscape architects, it's so important to understand this concept and how it works because it's going to affect our business. Alright? So remember, everything is relative to field capacity. Learn it, understand it, Have a beer with it, think about it, have another beer with it, and think about it. Matter of fact, have as many beers as you can and think about it. It will be way more fun that way. So field capacity, my ass, not so much field capacity is everything. That's it, guys. Have an awesome weekend, and we'll catch you on the next episode.

Hey, my friends. Welcome back to another episode of the Sprinkler Nerd Show. I'm your host, Andy Humphrey. This is episode X Y Z, because I honestly can't remember. Coming to you from my truck. We could call this an episode of truck talk, which I did, more towards the beginning of this show, not as of recent. And I am actually on my way to Chicago today. For a bunch of different events and business opportunities. And I had a couple things that were on my mind this week that I wanted share with you guys as it relates to service calls and warranty Andy just a few sort of future casting ideas about warranty that particularly came to my mind this morning. And I thought let's see. I thought I would start with I thought I would start with how you communicate with your clients. And this probably relates more to service clients, service calls, but could could relate to construction, but let let's look at it through a service call lens. And I had firsthand experience with this with a company in my hometown because my water tank failed. Still not exactly sure. The service guy actually came just yet this morning. I'm still not exactly sure what is wrong with it. I built my house in 2018. It is not a, you know, fine custom craft home. But it's also not a builder's choice, model home or or something on the low end. It's probably mid range. And What's interesting, I'll I'll get to this a bit later is this is not the first appliance that has failed in a six year old home. Let's just let's just put that out there. Not the first appliance that's failed. I'll give you the rest of the story here in a moment. And yesterday, actually, it was last night. My daughter came home, from her volleyball practice. It was late, let's say, 9, 9:30. And, she showers after practice, of course, and then she doesn't shower in the morning, and she goes, take a shower. And she comes down after she takes a shower, and she's like, hey. I I couldn't get the hot water on. The hot water's not working. Scratch my head. Andy I'm just thinking, okay. That's weird. Maybe there's something up with your, you know, your your shower. And then my wife said, you know what? I just washed my face before bed. And, yeah, I noticed that the water wasn't hot. So I, of course, would rather just jump into bed. It's 9:30 a night. I went down into the basement, looked at the hot water heater, and the water was definitely not hot. I looked at where the cord was plugged in to the outlet, Andy I then went to the breaker box. All the breakers were fine, but there was no power to the heater. So I, looked at where it was plugged in. It actually plugs into an electrical outlet right above it in the ceiling Andy thought, okay. Well, there's no power to this outlet. Why would there be no power to the outlet? Well, there must be something on this circuit that has a GFI that's tripped. It's my first thought. GFI must be something on this circuit that has a GFI and looking around the room. This is in our storage, storage room in the basement. It's not finished. But it's not, you know, a dungeon either. It's just a typical probably nine foot ceiling, storage room in their basement. Andy we have an air filtration system that is, attached to our forced air. Andy I'm looking up and I see its plug Andy its plug goes into the receptacle and the receptacle, sure enough, has a GFI on it. I unplug it. I hit the reset button. The little green light comes back on, and I'm thinking, yes. I am back in business. Andy just on the the problem. Cool. Plugged everything back in. Turned off the water heater, plugged it in, turned the pass back on. It starts automatically. I hear it fire up. I hear the exhaust fan kick in. And then 45 seconds later, pop. There goes the GFI again. Like, shit. What in the world is going on here? So then, of course, I did the whole the whole shebang over again, reset the GFI was hoping was hoping it would work, turned the hot water heater back on, and then sure enough, 40 seconds later, blew the GFI again. And this is, you know, by now, probably 10 o'clock at night. I don't want to fuck around with this anymore. So I just I let it be thought I had thought I had solved it with a GFI, but I couldn't solve the reason that the hot water tank was tripping it, and there was a little bit of water dripping out of the bottom into the basin. And I'm just thinking, alright. You know what? I'd better just bring in the professional. Wouldn't it be nice if if our clients always thought that about you guys? Let me not mess around with this myself. Let me bring in the true irrigation professional. And we know a lot do, but it's interesting that some don't until they farce around with it for 2 days. And only then do they call you guys in? And then they stand over your shoulder, and then they complain about here, about the price, Andy then they say, oh, that was it. Oh, I could have done that myself. Of course, I'm just making, making fun here. Andy we know some clients are like that. And again, I'll remind everyone, you get to choose your clients. So if that's the behavior, make a note, perhaps you don't service that account again, unless you need to, etcetera. All you always have a choice on who you do business with. So in any case, so this morning, I first thing I did was I called the company that that installed it. They're very well known, both residential residential installation and service company. And this is where the experience got really really awesome. And there's two parts that we to this, actually. The first part is that I I just googled them up real quick. Andy, you know, sometimes when you when you're on Google, your phone tries to locate you. However, Sometimes it just picks well, it shouldn't say picks random places, but it picks places that you're not just because of the data that's running through the either the cell towers or potentially the wifi network. So Google I didn't notice this, but Google had located me not in my hometown. So when I googled the name of this company, It brought up the same name, the same name I was looking for, but it wasn't in my hometown. And I didn't realize that the area code wasn't the same on the number. I called them up. They did not answer. They did not answer the phone. I left a message. Only then did I realize that I called the wrong company because I know that the company that I work with offers 247 phone support. They're not doing it, but they contracted out answering service, etcetera. I thought it was a bit odd that I re I I landed on a voice mail. So then I looked at my phone. Sure enough. That's when I discovered that I had called the wrong company because Google had placed me in the wrong area. And that also reminded me that I had remembered that this company offers 247 emergency support and that you never get a voicemail. So I thought I would just share that also is that you can, for a reasonable fee, offer that to your clients. And I'm not saying you should. Everybody has to make a decision on what is valuable for their business and their customers, but you could. And just because you could doesn't mean you should, but I just wanted to put that out there is that stood out to me as a homeowner requesting service from a different trade. I knew that I would not reach voice mail. So long story short, I'm gonna keep going here. I called the correct company. Got a wonderful woman on the phone. Again, I wouldn't if it was a man or a woman just happened to be a wonderful woman. She, brought up my account right away because the phone number I was calling in on matched up with their records. She had, my name. She had my wife's name, both of our cell phone numbers, all the information about the equipment that we have at our house, and then she was able to give me a window, a scheduling window. From 2, no, 10 to 2 to have a technician come out. And this is where it got really great. She she said that we would receive a text message when the technician was en route to our home Andy that we would receive the technicians GPS location. So we knew where the technician was and when the technician would be arriving. Andy I thought I would share both of these text messages with you just as an example of the technology that's available to improve the experience of your customers because I think I think that I'm not alone Andy the dissatisfaction that comes from needing to be at home from 8 in the morning to noon and not knowing when the technician's gonna come? Are they gonna come at 8, or are they gonna come at 1159? Do I need to be what if I wanna take a shower and they show up? All those kinds of things is not as, it's not that it's dissatisfaction. It's just thinking that there's a better way to do it. And today, I experienced the better way to do it. And and, before we get to the moral of the story, these that when I read through the text message that I'm gonna read you here, I noticed that the URL link was coming from go dot serviceditan.com. So immediately, I was able to recognize that this HVAC company uses service taking Andy that perhaps this great experience that I'm about to have is because of the service taking software. So here's the first text message that that we received. And what's also pretty cool is that it didn't just come to me. It came to both my wife and myself. To our to our cell phones on a text message. So here's the message. Hi, Andy and Megan. Galen from X Y Z Plumbing Andy Heating Systems is on the way to 547 Hidden Ridge drive, you can track his location here, and that's where the service Titan link comes in. Then it says, Galen is a dedicated, highly skilled HVAC service technician with years of proven industry experience provided with stellar customer care. Ask us about our great membership options If you haven't joined yet, call our office with any questions. Thank you for your business. Andy that's that's pretty sweet. We knew exactly when he was coming. We knew exactly where he was. Andy was at my office. They have a, a code to our garage so they could just get right in. Andy then he, sends another text personally well, I shouldn't say personally. He, the person sent a text to both my wife and I, after he was done the inspection because he hadn't yet fixed it, but he let us know what he had discovered. And this is what he said that this came from him. And I I don't know that this came through Service Titan software. Not sure. Don't care, but he says, hello. This is Galen from X Y Z Plumbing Andy Heating. I stopped by to look at your water heater, and it is leaking from inside the water heater tank. It is right on the edge of warranty Andy our office is seeing if we can get it covered under the factory 6 year warranty. The water heater was turned off when I arrived, but I have it running now. Do you want me to turn it back off or leave it running? Andy how great is that? We're not home. He's texting with us. He's cordial polite. Andy informative Andy working in our best interest to try to get it covered under the factory warranty. Andy, of course, I said, yeah, turn it on. We'd love some hot water. My shower this morning was was balls cold. Was shrinkage cold. Andy and then I ended up calling him right away because I wanted to ask him a few more questions. Question number 1 is how did he get it to stay on? Because every time I turned it on, I was popping the GFI Andy perhaps it was just it was still wet, and it was tripping a circuit, and it wasn't as wet any longer when when he was there. If If perhaps there is a leak or the bladder is blown and whatever else, I don't know exactly how these things operate. But I was like, yeah, man. Turn it on because I know is a problem. It'll pop the GFI. I'm not worrying about it being a safety issue. So, yes, please turn it on. We need some hot water. K? So that's just kind of a a I wanted to give a firsthand example as quickly as it had happened so I could speak from just just speak from not not truth, but speak from experience and having someone come to my house and and to be able to share how great the service is with number 1, we didn't have to be that number 2. We knew exactly when he was going to show up. We knew exactly where he was. And when he was done, he texted us right away and gave us the update. I don't think it gets much better than that until we get the bill. No. I'm just kidding. I know that it'll be reasonable And even even if it is, let's just say, higher than competitor b or see, do I really wanna call another guy to come out and spend all of of my own time with that? I that, you know, my time is worth more than the increased price of the next competitor. So also just just keep that in mind is I think as long as you do, you provide good service, you provide good value, you're professional, and your clients trust you. Than you you deserve to be paid for your worth. Cool. Alright. Now now let me share sort of the future casting idea about warranty. We built our house in 2018, Andy, I'm in my truck, and it is pouring rain here. So what I'm gonna do is I'm gonna hit pause on this recording. I wanna come back here as soon as Lorraine stops. Hang tight. I'll be right back. Alright. I'm back. Hopefully, you can hear me a little bit better now. Let's talk about warranty. Warranty is often a time frame. Right? 1 year, 2 years, 3 years, 4 years, 5 years, Andy get the idea. And with the failure of my water tank, I first thought why would my water tank fail in 6 years. And then to make matters worse, we have a stacked washer and dryer on the 3rd floor of our house. When I say Third Floor of our house, it's gonna sound like a little bit of mansion. But the first level is the walk in basement. So it's technically, like, the second level. That level is just my kid, 3 kids bedrooms, a bathroom, and my wife had this brilliant idea of a a washer and dryer on their level so that they do their own laundry. And all the kids stuff is on the floor. It's all it's, you know, what it's like, kids. Right? Their their mess is up there. We don't have to see, touch, or deal with their mess. They do their own laundry, but their washer has failed. Started getting grease on some stuff. There was a little bit of water in the basin underneath. And we have a service technician coming out to look at their washing machine. Previously, we have an induction stovetop. Our first one failed. We had it replaced. We are on our second dishwasher. First one failed. Last year, we had the coil on our not on the ace unit that's outside, but the coil that is on the blower unit in the basement failed. Andy so, you know, all these different appliances have all failed within 1 to 6 years, which makes me question a lot of things, but it also makes me think about What a warranty period really is? And I can understand a warranty period both from the manufacturing perspective and the the construction perspective. But I I stopped to think about what does time, how is time related to warranty, or how is time related to failure Andy is time related to failure. Let me give you an example. Let's say you install an irrigation system for somebody this summer. And this is their and let's just say for instance, this is their summer cottage, and they're in their summer cottage for 2 weeks out of the year. And during those 2 weeks, they like green grass. Well, so you fire up the system, Andy, you run it for a couple weeks before they get there. Andy they show up. Everything's green, running great. And then they and then they leave, and you shut down the system. So the irrigation system, let's just say, is only running 1 month of the year. Hypes are pressurized for 1 month valves actuate for 1 month. Outside of that, there's no power on the wire, and we know power causes corrosion when wires are wet. We know pipe fails when it's under pressure for long periods of time. I would expect a system that is run for only 1 month out of the year to last longer than a system which is run for 12 months out of the year. But when we look at warranty, let's just think manufacturer's warranty. Take any irrigation manufacturer and let's look at the valve warranty. Some valves have 1 or 2 years, some have 5 years. But again, an irrigation system that is operated 1 month out of the year I would expect to last longer than 5 years because if you add up 1 month a year times 5 years, that's 5 months of operation. Versus a system that has run 12 months out of the year after 5 years, that's 60 months of operation. Yet the same warranty period applies. And we could stop and say, well, how is the manufacturer supposed to know how long the system has been in operation? And I would say, absolutely. They don't know. They do not know. But what if they did know? That's the question I asked. What if they did know? Now let's think about, my home. I have 3 kids there. My son came home from college. She's 20. My daughter's a senior in high school. My other daughter's a freshman. We use the crap of our house. What I mean, we use the crap out of it means we're cooking. We're taking 5 showers a day. We're doing lots of laundry. We're really using our appliances to the maximum capability of of of that. I mean, unless we had 2 more kids at You're really not gonna use appliances more than my family does. We're probably peak appliance users. K? But what if a couple, and I'm gonna stereotype here for a moment. What if a couple was seventy five years old? And they had no kids at home, and they ate out every day. So they never really used dishwasher. They never used their stovetop. They did laundry, you know, maybe one load, one load a week, maybe, you know, they don't they they take one shower a day. They're they're not putting the same wear and tear, on the equipment. They're not using it for, you know, the same amount of time. So I would expect their equipment to last definitely last the warranty period Andy la it lasts much longer. That got me thinking about my hot water tank. Okay? We we use lots and lots and lots of hot water. We're probably doing at least 2 loads of laundry every single we're taking 5 showers, at least, because sometimes my kids shower in the morning Andy the evening, we are using a ton of hot water. So that I thought, well, what if there was a way to know how many gallons of hot water my tank has you know, heated since we installed it. Wouldn't wouldn't that be a good way to know when it might fail next? Or could that be a better way to know when it might fail versus time? Because time, if you don't use something, I mean, certainly, something could seize up because it's not maintained, but if you're not using it, you're not it it likely wouldn't fail as quickly. So what if there was a way to know either, you know, how many gallons of hot water went through my tank Andy or, you know, how many hours, let's say the unit was heating for, something like that, a way to count or or put a value on the usage as a statistic so that a warranty might say something like this, totally making this up. For my hot water tank. Maybe it would say something like, warrantied up to 100,000 gallons of heated hot water or 5 years, whichever comes 1st. Why does why is that not how we warranty appliances? Take a dishwash Same thing. If you're doing one load of dishes in the dishwasher, every single day, 365 wash cycles, It's possible that the somebody in 5 years isn't doing 365 wash cycles. So why not attach the warranty to either time or cycle count usage, etcetera, or whichever comes first? Andy that way, I would know or could know in advance. Wow. We just, we just ran the last drop of hot water through our hot water tank. It is now out of warranty, which also means now we're look now we're at a period where we're in high usage. We've we've put this number of hours on this device Andy there's a potential for it to fail. So maybe we want to, you know, set some money aside because we know this can fail soon. It just find it interesting that there isn't a, like, a usage statistic, a counter, something to track how long a piece of equipment Andy appliance, in this case, has been used because I think that would be more indicative to its failure than simply time. And maybe the closest analogy would be a vehicle. And I don't know how all the warranties work, but it might say something like you know, 2 years or 20,000 miles, whichever comes first. Do you buy a new vehicle? Hey. Manufactured warranty is good for 20,000 miles or 2 years, whichever comes first. Because they know that things start to break down and fail when the car is put to use versus it just sitting there. So and in any any case, it the failure of my hot water tank caused me to have some thoughts about warranty that I had not had before Andy it might be something for you to take into consideration when you look at a warranty period, especially as it relates to your labor. Because a manufacturable warranty, they have a different warranty than you do. So you might, you know, look at how how often or how much use is gonna be put on an irrigation system. Let's say Southern California versus Boston. Right? Boston's not in service for 5 months out of the year. California's in service for 12 months out of the year. So a 1 year or 2 year warranty is a is different. There's different risk involved because the system is not operating for the same periods of time. And I don't know how to solve it. I'm just putting ideas out there just based on my own experience from something totally random like a hot water heater, but maybe some point manufacturers will start putting use counters on devices so they know, when something might fail or if it failed unexpectedly because it had only been the valve had only opened and closed four times, and now it's failed versus 4000 times. So I think you get the idea of beat this one in enough. Thank you so much for listening Andy, you know, what's your thought? What is your sideways thought? What have you thought about or experienced recently that has caused you to think of something in a different way? Would love to know, shoot me a text, 208-908-3229. That is my personal cell phone. I welcome all comments, feedback, anything you're up to, let me know. Love chatting with all you guys. Thank you for listening and, go out there. Have a great day. Try something new. Experiment. Let me know how it goes. Cheers, guys. See you on the next episode.
