The Sprinkler Nerd Show

Andy Humphrey: Hey, what's up, my friends? Welcome back to another episode of the Sprinkler Nerd Show. I'm your host, Andy Humphrey. Today, I'm going to share with you—how do I describe this?

Andy Humphrey: A question that came into Sprinkler Supply Store for me that turns out to be, I think, some really relevant content to discuss with you guys. And I think probably most of you could relate to this question that the homeowner has. And, I wanted to tie this together in a couple of ways. Number 1, we're having a lot of success, and we have had a lot of success with software on our e-commerce site called LeadFerno. L-E-A-D F-E-R-N-O, LeadFerno, and LeadFerno is a texting tool that acts like web chat.

Andy Humphrey: And so what happens is there's a little pop-up, which obviously can be annoying at times, that, on the website, to reach us, to reach customer service, but instead of chatting there, it redirects through the phone so you can use your phone and the text message feature or messenger to communicate with us. And personally, I wish more sites used this because I would say half the time when I'm on some other website using the chat feature, you know, I'm waiting for someone, let's say, for the chat to get back to me. So I have another tab open, and I don't have my volume up. And then I get distracted, and then 30 minutes go by.

Andy Humphrey: And I think, oh, shoot. I had a live chat going. I forgot about it. I go back to the tab. And then the chat has ended because I didn't respond, and it just seems like web chat is good if the other person is right there and they're chatting with you quickly. But that's not always the case.

Andy Humphrey: Sometimes the chat agents have to go and look something up or tell you to hold, and sometimes you have to leave your desk. You just can't sit there on chat. And so what we have found is that by using the phone as the texting tool, which it's very good at, then people can text wherever they are. You know what? If you gotta get up and get in your car and drive somewhere else, we can still text with you because you have your text device in your pocket instead of having to sit at your computer.

Andy Humphrey: It's been a great way for people to send us pictures. "Hey, I need a replacement diaphragm for this valve. I don't know what valve this is. Okay, great. Send us a picture." And so LeadFerno has been an amazing tool for communicating with our customers because it doesn't require them to be locked to their computer screen. They can text through their phone. They can also save the number and text us any time.

Andy Humphrey: And if you'd like to try this, go to sprinklersupplystore.com. It'll pop right up, send us a message, and that will come into our text service, which you can either manage through a web browser, or you can put the app right on your phone. Then you can text back and forth with your customer. And I think that there are probably some parallels that if you have, you could be a solo entrepreneur in the irrigation industry, and maybe that would work. But there might be some parallels for capturing leads through the website and getting back to people quickly, via LeadFerno. So check it out and, you know, give it a try.

Andy Humphrey: This is not sponsored by LeadFerno. I just thought I would share because the topic for today, which is the question that this homeowner from Houston had—the inquiry came in through LeadFerno. So that's how we actually captured this. And I just thought that it would be a pretty fun way for me, specifically not to have to dream up new content to share with you. So this is a real customer inquiry that I'm going to read to you right now.

Andy Humphrey: Actually, what I'm going to do is have an AI voice read this out loud so that it doesn't sound like me, and then we can talk about the response. So I'm going to roll the intro here, and then we'll get right into this question coming in from Roger in Houston. If you're old or new, who designs, installs, or maintains high-end residential, commercial, or municipal properties, and you want to use technology to improve your business to get a leg up on your competition, even if you're an old school irrigator from the days of high-olive systems, this show is for you.

Roger: Hey, Andy. This is Roger from Houston. Thanks for maintaining such a helpful website for homeowners with sprinkler systems. For 26 years, we've enjoyed excellent water pressure due to our location downhill from the city's water supply. Unfortunately, this year, the pressure decreased unexpectedly, before being restored to around 80 PSI.

Roger: This was sufficient to operate our sprinkler systems effectively. However, the city had to reduce the water flow to 60 PSI at the request of a few residents who are experiencing excessive pressure. This adjustment has rendered our sprinkler system, as well as my neighbors', nearly useless. This situation was confirmed by two independent sprinkler experts.

Roger: From what I understand, the city is considering the installation of irrigation booster pumps to address the issue. If excessive water pressure continues to be a problem, residents might be able to adjust their pressure-reducing valves, PRVs, to suit their needs, allowing the city to maintain an 80 PSI flow through the main pipes. Also, Andy, you mentioned you're available via text, email, and phone calls. I'd appreciate a chance to discuss this more at your convenience if you're still offering consultations. Our property has 7 irrigation zones, though currently, we're only using 4.

Roger: As I mentioned, for over 2 decades, we've had reliable water pressure ranging from 80 to 100 PSI. Thanks to our favorable location. My home and sprinkler system each have their own PRV set to 80 PSI. Furthermore, I received a voicemail from a city supervisor who, like others, seems unaware of the underlying issues with our water system. Despite longstanding high water pressure, recent adjustments have significantly lowered it to 60 PSI, which is insufficient for our needs. Our systems are becoming ineffective due to these changes, not due to any alterations in the city's water pressure policy.

Roger: But because of how the valves are being managed. Additionally, I spoke with Ashley at Waterworks, expressing my concerns that Ken, a supervisor, might not be fully aware of the situation here. Unlike two other colleagues who have been with the city for 35 years, after enjoying stable water pressure for so long, it's frustrating to face these sudden changes. I appreciate any thoughts you might have.

Andy Humphrey: Okay. So if that wasn't clear, I would just say hit the back button, you know, go back, hit 30 seconds, backtrack, go back and play it again. But essentially, Roger appreciated our website. He'd watched a bunch of YouTube videos I'd made, I think he had watched one, specifically on pressure. And so he's encountering a situation in his neighborhood, and he's been, as you said, in his neighborhood for 26 years.

Andy Humphrey: He's always had awesome pressure. And apparently, the city lowered the pressure, and he can't get a clear answer. But this brings up a really interesting point about pressure because it's not always the same. Andy, I'm not sure—you could correct me if I'm wrong—if this might be the case in your area of the country. I don't think cities guarantee a minimum pressure rating either.

Andy Humphrey: So I don't think you can get something from the city that says, "We guarantee 65 PSI to your house." I don't think that exists. And, you know, the system's twenty-six years old. If it used to run great at a higher pressure, my first thought is that it was likely designed for that higher pressure, which is another great conversation piece because I think it would be very important to document the specification of your design. In other words, remind the homeowner that you, or the commercial client, that you are designing the system to operate at 60 PSI downstream of the backflow at 15 gallons a minute. For example, put that in your contract if that is what you're designing the system for so that if the performance of the system becomes questionable at some point in the future, and it turns out that it is because of pressure, and to diagnose this, you've tested the pressure, and it's 45. Downstream of the backflow, then you can reference your original signed contract. It states you designed the irrigation system at 65 PSI, downstream of the backflow preventer, and it is now not at 65.

Andy Humphrey: So this is not this is not caused by you. It may still be, you know, air quotes here, "Your problem," but it doesn't mean that your system is now not performing; it means the pressure is not the same as it was when you designed the system. So I think that, you know, as we start to talk a little bit more about pressure, it's important to document some of these things and then see a real-world example here coming from Houston where the city pressure is not what it was.

Andy Humphrey: Apparently, it was because a couple of homeowners complained that their pressure was too high, so they lowered it for everyone, which, again, I haven't—I have no way to prove this or not. I would think it would be easier for those couple of homes just to put in a PRV. Instead of lowering it for everyone and then requiring those who need more pressure to put in a booster pump. But again, it could be. If you recall a couple of episodes ago, when I was talking with Paul Bassett, he mentioned that sometimes aging infrastructure, in cities or cities with aging infrastructure may decide to lower the pressure a bit to try to preserve the integrity of their utilities.

Andy Humphrey: And if this house is twenty-six years old, obviously, it's not new. It could have been new 26 years ago, but we don't know this. It may be aging infrastructure. So perhaps, again, don't know this to be true. Perhaps the city has elected to lower the operating pressure of their mains to preserve the integrity of their piping structure.

Andy Humphrey: And that's why this is occurring. So another thought would be, and maybe you guys do this that just comes to mind, that let's say, for instance, the operating pressure that you have estimated to be downstream of the backflow preventer is 55. Might it be a good idea to design the system at 45 PSI so that you're leaving some room for it to go down? Or if the pressure downstream of the backflow is 70, maybe design the system with 50 PSI. That way, there's room for the pressure to drop over time versus designing the system for the exact amount of pressure that is available and or the exact amount of flow, maybe it would make sense to leave a little bit of room.

Andy Humphrey: Again, you could document this pressure. So if it was 70 and you said you designed the system at 50, then you've left some room for the city to drop the pressure over time or other instances where the pressure may not be what it was when you designed the system. So that was the other piece that caught my mind for new installs. Maybe it would be a worthy idea to be conservative with your designs and not design to the maximum of the pipe size and or the pressure, but allow some room for it to drop. And there's probably a bunch of you guys listening to this.

Andy Humphrey: Yeah. That's what we do. Okay, Andy. We got that. We do that anyway.

Andy Humphrey: So congrats if that is you. And if not, maybe just something to consider. And yeah. So just, you know, my thoughts here on pressure, and I like this because this is a real-world example. I didn't make this up.

Andy Humphrey: All I did was run it through some AI so that it could read it aloud and not be in my voice, but be in the voice of Roger from Houston. And I would love to know how you approach situations like this and how well, if at all, you document pressure on your irrigation systems. Was talking with Denny, customer service manager here this morning when we were reviewing this inquiry that came in. And I thought, man, maybe it would be a good idea when you're doing spring startups to, you know, put a pressure gauge on the system, document the static pressure on the site, commercial or residential, while you're doing your spring startup, make a note of it, so that if anything were to start occurring later on in the season, you know what your pressure was at the time you started up the system and you can use it as a reference point. So again, I don't know how many of you are doing it.

Andy Humphrey: If you are, fantastic. If not, give it some consideration. That, it may be a good idea not only to record the static pressure at the time of installation but also the time of spring startup and perhaps the time if you take over maintenance on a system. If you've just taken over maintenance and it's a ten-year-old irrigation system, you know, you might decide to check the vitals and document the vitals, maybe write them down and take a picture. I'd probably say take a picture of that pressure gauge, on the backflow or on the hose bib.

Andy Humphrey: So you've got more clear documentation should something arise. Yeah, I guess those are my thoughts, guys. If you have anything else you would like to add, feel free to send me a text message. As always, love chatting with you guys, and I don't think I shouted out to you before, Isaac, but appreciate you reaching out recently. Good luck down there in Florida.

Andy Humphrey: And if anybody wants to say hello, my cell phone number is area code 208-908-3229, that does not go into LeadFerno. That actually comes into me directly. So if you text that number, you get me. And I always love hearing from you guys. And if there's anything you wanna add about pressure, how you use it, how you document it, what you do if a system that you either installed or maintained has a pressure problem.

Andy Humphrey: What do you do first? What do you do second? How do you describe the situation to the client? So, again, thank you for listening. Please share this podcast with a friend or colleague or landscaper or landscape architect, irrigation designer. That would mean a lot to me, and hope you guys have a great weekend.

Andy Humphrey: Thanks so much, and we'll see you next week on another episode.

In this insightful episode, Andy and Paul reflect on their recent project, delving into the complexities and vital importance of pressure in irrigation systems, especially pertaining to a vast green rooftop. While the specifics of their project remain confidential, the co-hosts openly discuss the general scope, centered around the deployment of wireless sensors for data analytics, enabling the client to monitor conditions of the landscape more accurately.

They outline the project's challenges, from the discovery of low water pressure on the rooftop to the absence of water meters and pressure gauges, illuminating how their technology provides the client with crucial insights previously obscured. Emphasizing the critical role of monitoring, they illustrate how their wireless sensors and dashboard platform reveal the "vital signs" of water infrastructure, much like a medical check-up reveals the health of a human body.

Paul and Andy share anecdotes from their fieldwork, where they identified a significant leak due to a mainline break, likely caused by inadequate winterization. The revelation of this break underscored the hidden nature of water problems and the need for meticulous observation and the right tools to diagnose and manage such issues effectively.

The episode pivots to a discussion about data collection, particularly the innovative use of wireless technology. They replaced a failing wired system with a more robust wireless one, including soil moisture sensors and water meters with both analog and digital capabilities. This transition from wired to wireless signifies a substantial improvement in monitoring and managing the system, with the potential for real-time insights and rapid problem detection.

Throughout the podcast, the hosts compare an irrigation system's vital signs to human vital signs, with pressure transducers acting like a blood pressure monitor, providing real-time feedback on system health. They argue that knowing the pressure in an irrigation system is paramount, even more crucial than flow rates in some cases, as it can instantly signal issues such as leaks or system malfunctions.

A central theme is the emphasis on the importance of starting diagnostics at the water source rather than the controller and the need for constant pressure monitoring to ensure system integrity. This approach could potentially transform maintenance routines and system diagnostics in the industry.

Key takeaways and insights include:

• The "vital signs" of irrigation systems, akin to those in medical practice, are crucial for diagnosis and management.
• The conversion from wired to wireless systems represents a significant step forward in monitoring capabilities.
• Real-time pressure monitoring can reveal issues that flow monitoring might not, highlighting the need for comprehensive diagnostic tools.
• The hidden nature of water systems necessitates the adoption of visual and digital tools for accurate assessment.

Andy and Paul's dialogue underscores their commitment to innovation and their continual learning process, as they seek to enhance their understanding and management of irrigation systems. Their hope is to develop tools that will become industry standards, ensuring that businesses can effectively manage their water systems.

As the episode concludes, the sense of partnership and mutual respect between the two is palpable, as they look forward to their next project with anticipation. Listeners are left with a deeper appreciation for the intricacies of irrigation systems and the evolving technologies that monitor and manage them.

Key Points:

• The importance of pressure in monitoring irrigation and plumbing systems.

In this episode, Andy, delves into the nuanced debate of context versus control within the realm of management, particularly focusing on the irrigation industry. This concept, inspired by an episode of the Tim Ferriss show featuring Reed Hastings, co-founder and former CEO of Netflix, challenges traditional management styles by advocating for a more empowered approach to leadership. Through Reed Hastings' insights and his own reflections, Andy explores how setting clear contexts rather than imposing strict controls can lead to more innovative and motivated teams.

• Inspiration from Reed Hastings: The idea of context vs. control was sparked by Reed Hastings' discussion on the Tim Ferriss show, emphasizing creative management styles over conventional, control-based approaches.
• Definition of Context vs. Control: Control is described as a rigid, micromanagement style, whereas context provides goals and empowers employees to achieve them in their own way.
• Impact on the Irrigation Industry: Andy applies these concepts to the irrigation industry, suggesting that understanding the 'why' behind actions can lead to more engaged and self-sufficient teams.
• Reed Hastings' Metaphor: The comparison of industrial and creative companies illustrates how context-driven management can lead to innovation and unique customer experiences.
• Management Philosophy: Andy expresses his preference for a management style that sets a clear context, allowing for autonomy and self-guided decision-making within teams.

• Setting the context in management involves clearly defining the goals and the 'why' behind tasks, and empowering team members to make decisions that align with company objectives.
• Context-driven management can foster a culture of innovation and flexibility, particularly beneficial in creative or service-oriented industries.
• Understanding and implementing the context vs. control management style can enhance team motivation, satisfaction, and overall performance.

In the episode of the "Sprinkler Nerd Show," host Andy Humphrey and his guest, Paul, embark on a detailed discussion about the technical aspects of irrigation systems, specifically focusing on the importance of flow and pressure monitoring.

Andy begins by recounting his observations of inefficient sprinkler systems at a resort, noting that a vast majority are functioning poorly. He suggests that the resort's irrigation system is so ineffective that it might as well not be in operation. This real-world issue leads him to reflect on the broader implications for the irrigation industry, particularly the innovations in flow and pressure monitoring technologies.

To dive deeper into the topic, Andy introduces a thought experiment based on the game "Would You Rather?" The game is simple: one person poses a dilemma in the form of a question starting with "would you rather," and the other person chooses one of the options. Andy uses this format to pose a significant question to Paul: Given a choice between flow monitoring and pressure monitoring for a commercial irrigation system, which one would you choose?

Paul acknowledges the complexity of the question. Traditionally, the industry relied heavily on flow monitoring, with pressure monitoring being a more recent development. He expresses a preference for both but understands that the question demands a choice.

The conversation shifts to an in-depth analysis of the two monitoring methods. Flow monitoring is essential for understanding water usage and identifying leaks through abnormal flow patterns. It is a vital tool for water conservation and efficient system management. On the other hand, pressure monitoring provides diagnostic insights that are not immediately apparent through flow data alone. For instance, pressure fluctuations can indicate issues with the municipal water supply that could affect irrigation system performance.

Andy and Paul discuss the scenarios where one type of monitoring may be more advantageous than the other. For example, Paul shares an anecdote about a situation in Washington, D.C., where several irrigation systems under his management experienced a drop in performance due to a reduction in municipal water pressure. This incident underscores the value of pressure monitoring, as it can provide early warnings about changes in water supply that are beyond the control of the irrigation system manager.

The discussion delves into the practicalities of managing large-scale irrigation systems. They examine how continuous logging of pressure data can provide insights that intermittent readings cannot. Paul points out that as municipal water systems age, providers often reduce water pressure to extend the lifespan of the infrastructure, impacting irrigation systems connected to the municipal supply. This practice, while beneficial to the municipal system, can have unintended consequences for irrigation, making pressure monitoring an invaluable tool for understanding and adapting to these external changes.

As they further explore the nuances of flow and pressure data, Andy and Paul consider the implications of having one without the other. They agree that while flow sensors are crucial for accounting for water usage, pressure sensors offer a more sensitive diagnostic tool that can help explain why certain anomalies in water usage may occur.

Andy then offers a perspective that connects the physical observations of an irrigation system to the data provided by sensors. Walking around the resort, he notices visible signs of system failure, such as broken infrastructure and poorly performing sprinkler zones. He posits that either a flow sensor or a pressure sensor could indicate such problems, but each does so in a different way. A flow sensor could detect a broken pipe through abnormal water usage, while a pressure sensor could indicate a drop in performance due to pressure changes.

As they wrap up their discussion, both Andy and Paul lean towards the importance of pressure monitoring when forced to choose. They liken pressure sensors to a doctor checking blood pressure—a critical first step in diagnosing a patient's health. They explore the idea that while flow is a measurement of consumption, pressure provides a more immediate reflection of system health.

Paul highlights that from a management standpoint, pressure data is more actionable, especially when monitoring remotely. He also notes that installing pressure sensors can be simpler and less intrusive than installing flow sensors, which often require cutting into the mainline. This ease of installation makes pressure sensors a more attractive option for quickly and cost-effectively assessing system performance.

In conclusion, Andy and Paul's conversation in the "Sprinkler Nerd Show" episode brings to light the strategic importance of choosing the right monitoring tools for irrigation systems. They discuss the trade-offs between flow and pressure monitoring and conclude that while both are essential, pressure monitoring may offer a slight edge in terms of diagnostics and system management, particularly when faced with the constraints of municipal water supplies and the need for remote system oversight. Their dialogue is a testament to the evolving technological landscape of irrigation and the need for professionals in the field to adapt and make informed decisions about the tools they use to manage water resources effectively.

In the latest episode of the "Sprinkler Nerd Show," host Andy shares his insights on the importance of being unconventional in the irrigation and landscape industry. Below are key thoughts highlighted from the discussion:

• Embrace Unconventionality: Humphrey emphasizes the need for businesses to stand out by being the "orange in the apple bin," advocating for a distinct approach to conventional industry practices.

• Question the Status Quo: He encourages listeners to think differently by asking unique questions to clients, proposing innovative solutions, and redefining the customer interaction experience to set themselves apart from competitors.

• Redefine Industry Standards: By adopting unconventional methods, such as integrating advanced technologies like soil moisture sensors, businesses can lead the market and force competitors to follow their innovative practices.

• Zig When Others Zag: Humphrey highlights the advantage of going against the grain, suggesting that by choosing less traveled paths, businesses can find shorter lines to success, symbolizing less competition and a more distinct market position.

• Challenge Perceived Limitations: He inspires businesses to question why certain practices are avoided in the industry and to explore these areas as potential opportunities for innovation and differentiation.

• Change the Game: Humphrey posits that by being unconventional, businesses can not only set new trends but also change the rules of the game, compelling even large competitors to adapt to these new standards.

• Seek Opportunities for Innovation: The discussion suggests looking for what is missing in current offerings and exploring unconventional solutions that could potentially change the future of the industry.

• Encourage a Mindset of Exploration: By sharing his upcoming vacation plans and the prospect of unconventional thoughts it might inspire, Humphrey models the behavior of seeking inspiration from outside the industry to bring fresh ideas to one's business.

• Value of Continuous Learning: Ending on the note of appreciating his audience for seeking knowledge through podcasts, Humphrey underscores the importance of continuous learning and staying open to new ideas as a way to achieve unconventional success.

This summary captures Andy Humphrey's message of leveraging unconventional thinking as a strategic tool for differentiation and leadership in the irrigation and landscape industry, encouraging businesses to innovate and redefine industry standards.
