The “Dig a Bigger Hole Rule” of Irrigation

The “Dig a Bigger Hole Rule” of Irrigation: Lessons Learned in 27 Years in the Business

When I first entered the irrigation business nearly three decades ago, I made my fair share of mistakes like many newcomers. One of the most memorable—and consequential—was what I now call the “Dig a Bigger Hole Rule.” It was a lesson that took time and experience to fully understand one that I share with new irrigation professionals every chance  The crux of the lesson? Don’t cut corners by digging a small hole just for the time or energy. While it might seem like a shortcut, it only leads to more headaches, costly repairs, and wasted time.

Let in the long run me take you back to my early days in the industry, around Austin, Texas, where I first learned this lesson the hard way.

The Rookie Mistake: Small Holes, Big Problems

When I started in the irrigation business, I was young, eager, and eager to prove myself. We were often under tight deadlines and working with limited resources. It made sense to me at the time to dig smaller holes to access broken pipes or faulty components. After all, the smaller the hole, the less effort and time spent digging, right?

It seemed like a good idea in theory. I thought by keeping the excavation minimal, I was saving time, energy, and labor costs. I figured I could get in, make the repair, and be on my way, all while keeping things tidy and efficient.

But, as I soon found out, this approach was anything but efficient in the long run.

The Problems with Small Holes in Irrigation

Digging small holes may seem like a good idea at first, but it quickly became clear that it created a slew of issues. First and foremost, small holes made it difficult to properly align the fittings. If I didn’t have enough space to work with, getting the correct angles on pipe joints and fittings was a nightmare. The lack of space made it nearly impossible to ensure everything lined up precisely, which led to misaligned fittings, poorly solvent-welded joints, and, ultimately, leaks.

Additionally, small holes created a problem with water drainage. After cutting into the pipe, there was often residual water left in the hole. With a small excavation, there was nowhere for that water to go, and it just pooled in the area, making it a mess to work in. The water, dirt, and debris from the soil also tended to infiltrate the system, causing even more problems down the road.

And that was just the beginning. The real issue lies in the long-term effects. When debris or soil gets into the lines, valves, and fittings, it causes all sorts of havoc. Dirt and particles can clog the lines, affecting water flow and causing the system to malfunction. The particles can also get caught in valves, causing them to stick or fail entirely.

Furthermore, poorly aligned and solvent-welded fittings don’t hold up over time. They may not leak immediately, but over weeks and months, they weaken, leading to eventual leaks that can be costly to repair. I learned the hard way that these minor oversights—created by cutting corners in the digging process—often turned into much bigger headaches down the road.

The Turning Point: Embracing the Bigger Hole

It took me a while to fully understand the value of digging a bigger hole. At first, I resisted the idea because it felt like more work. I wasn’t excited about the prospect of extra digging or additional effort. But after a series of frustrating repairs and the realization that I was just digging myself into more problems, I finally decided to try something different.

This is when I discovered the importance of giving myself the room to work. Digging a larger hole actually made the repair process more efficient and far less stressful.

By digging out a larger area, I could easily access all the components and get a clearer visual of how the fittings and pipes should be aligned. I could make sure everything was connected properly without being hindered by tight space. A larger hole also allowed for better drainage, which was crucial for keeping the area dry. If any residual water remained in the trench after making the repair, it could naturally flow away from the work area instead of pooling in the excavation.

Most importantly, a larger hole meant there was less chance for dirt, debris, or soil to get into the system. When you have the space to move around, it’s easier to keep everything clean, which reduces the risk of contamination in the lines. And, as anyone in the irrigation business knows, keeping the system clean is one of the most important aspects of maintaining long-term functionality and reliability.

The “Dig a Bigger Hole Rule”

Through trial and error, I came to understand what I now call the “Dig a Bigger Hole Rule” of irrigation. This rule is simple: when you’re making repairs or working on an irrigation system, give yourself plenty of space to work. Digging a larger hole may take a little more time and energy upfront, but it will save you a great deal of frustration, time, and money in the long run.

Here’s why:

  1. Proper Alignment of Fittings: A larger hole gives you enough room to carefully align your fittings and pipes. This ensures that everything is properly solvent-welded and securely in place, reducing the risk of leaks or future failures.
  2. Easier Drainage: If there’s any residual water left in the system after cutting into the pipe, a larger hole allows it to naturally drain away from the work area. This keeps your feet dry and prevents the hole from becoming a muddy mess.
  3. Less Debris Contamination: More space means less chance for dirt and soil to fall into the system, ensuring the lines, valves, and fittings stay clean and free of obstructions that could cause clogs or system failures.
  4. Long-Term Durability: Properly aligned, well-sealed fittings and a clean system are less likely to fail prematurely. A bigger hole ensures that you do the job right the first time, which means fewer repairs in the future.
  5. Increased Efficiency: It may feel like more work at first, but a larger hole makes the repair process much smoother. You’ll find that once you have the space to move and work comfortably, the job becomes quicker and more efficient overall.

Passing on the Lesson: Mentoring New Irrigation Pros

After 27 years in the irrigation business, I’ve seen a lot of young professionals make the same mistakes I did. Newcomers often want to save time by cutting corners, whether it’s digging small holes, skipping necessary prep work, or ignoring the importance of proper system maintenance.

But the best piece of advice I can give to anyone entering this business is simple: embrace the “Dig a Bigger Hole Rule.” It’s a lesson that will serve you well throughout your career. By taking the time to do things right, you’ll save yourself countless headaches and avoid the frustration of dealing with preventable leaks, clogs, and repairs.

Remember: Extra Digging Up Front Can be Helpful!

The “Dig a Bigger Hole Rule” may seem like a small piece of advice, but it encapsulates a broader philosophy about the value of doing things right from the start. When it comes to irrigation, shortcuts can be costly in both time and money. The next time you’re faced with a repair or installation, remember that a little extra digging upfront can save you a lot of trouble down the line.

After 27 years in the business, I can confidently say that this lesson—though learned through mistakes—has been one of the most valuable I’ve taken away. And now, I’m passing it on to the next generation of irrigation professionals so they can avoid the same pitfalls I faced. Because, as it turns out, sometimes the bigger hole really is the better option.

The Importance of Irrigation in the Texas Climate

Unpredictable rainfall and high temperatures can make it difficult to grow plants in Central Texas. Your ability to irrigate your lawn or garden can be the difference between having beautiful green plants or a struggling landscape that downgrades the look of the property. Learn more about the importance of irrigation in the Texas climate below.

The Tough Climate in Central Texas

According to the National Weather Service, the Central Texas area averages about 35 inches of rainfall every year. However, much of the rain falls in late spring and autumn, leaving the prime growing season of summer drier than other times of the year.

When rain is not falling regularly in Texas during the summer, when temperatures regularly reach the 90s or higher, you may need irrigation to keep your garden and lawn vibrant and green. 

In addition to having an irrigation system available, homeowners in the Leander area may choose to use certain types of grass, garden plants, and landscaping flowers that can stand up to drought. Should your residence end up under watering restrictions during dry conditions, you will be glad to have drought-tolerant plants and an efficient irrigation system.

Managing Water Use in the Leander, Texas, Area

The importance of irrigation in the Texas climate is clear since so many people here need water for lawns, gardens, and crops; however, it can be difficult to conserve enough water for everyone’s needs, including agriculture.

When conservation is highly important to you, trust an irrigation repair and installation service to create a system that focuses on:

  • Efficiency in water use
  • Using technology to monitor irrigation needs
  • Delivering water in the most sustainable way
  • Watering at times of the day that are most efficient

However, any irrigation system must not sacrifice the health of the plants by excessively reducing water usage. A trusted professional team can give you the perfect balance between conserving water while irrigating and keeping your plants vibrant.

Managing the Importance of Every Drop of Water

The right irrigation system can reduce waste when watering lawns and gardens. Your irrigation system design can use precise application methods that conserve water. The system can ensure the majority of the water reaches the plants rather than being lost to soil erosion or evaporation.

Any irrigation system you use needs to be fully adjustable. You should be able to reduce your water usage in the days after rain rather than saturating your lawn or garden unnecessarily. Some irrigation systems may even automatically apply water at times when soil measurements show that the soil and plants are in need of water application.

We joined the Liberty Hill chamber

Howdy yall!  I’m proud to announce we’ve joined the Liberty Hill chamber of commerce.  We’ve been serving the Liberty hill area for nearly three decades, seems like we would have joined before now?!  member page for American Irrigation at libertyhillchamber.org

Ashly and I were driving the area and went up to the H-E-B in Leander and were joking about all the changes especially in Seward Junction.  Do y’all remember when that corner had the old Smokey Mo’s on it forever ago, and a flashing light?!

My Dad was talking to me as we were heading out to hunt the other weekend about when he was in college going to Baylor he would run between Burnet and Waco in his old Mustang.  He remembered 29 being a two lane road and there wasn’t much around going from Burnet to Georgetown.  I feel old when I find myself reminiscing about the same changes my Dad tells me about.  I suppose that is the way life works we always fondly remember the old days.

Enough ramblings of yesteryears for now!  Be sure to let us know if you know anyone that is in need of a new sprinkler system or needs help with any type of sprinkler repair in Liberty hill.

Top 5 Sprinkler Issues Austin, TX Homeowners Face and How To Fix Them

Property owners in Leander, TX, and around Austin depend on their irrigation systems to keep their lawns green and healthy. Over time, even the best systems run into problems that can waste water and cause landscaping and property damage.

American Irrigation Repair discusses below the five leading sprinkler issues that affect irrigation systems in Austin, TX, and how to deal with them.

1. Clogged Nozzles

Dirt, sand, and debris often accumulate in sprinkler nozzles, obstructing water flow and causing uneven watering — leading to dry patches on your lawn and wasted water.

The easiest way to clean the nozzles is with either a small screwdriver or a small metal pick.  Basically, you want to knock out any debris in the nozzles to get the full pattern back.  

You may need to flush the nozzle to remove debris.  To do that, turn off the sprinkler system and unscrew the nozzle from the sprinkler head. Rinse the nozzle under running water and use a small brush or pick to remove debris. If this doesn’t get the heads to work or improve performance, you can call in an irrigation expert to inspect the system for other underlying problems.  

2. Leaking Pipes

Because they directly affect water pressure, leaks lead to low water pressure, inadequate watering, and high water bills. Of course, leaks also cause localized flooding in your yard. Leaks can develop from ordinary wear and tear, damage from tree roots, or from freezing and bursting in winter.   Sprinkler heads do have a life and after many up and down cycles seals and plastic can wear and develop marring that will cause leaks.  

An irrigation expert will identify the leak using appropriate technology and tools. After pinpointing the leak, a technician will expose the damaged area with targeted excavation, and then patch the leak or replace piping, depending on the extent of the damage.  

3. Sprinkler Head Damage

Lawnmowers, utility vehicles, foot traffic, pets, or extreme weather can all break or damage sprinkler heads. A broken or misaligned sprinkler head-in leads to uneven irrigation, water waste, and landscaping damage. With Austin, TX water rates being so high, and water restrictions being severe it’s best to fix leaks right away.  

An irrigation technician carefully removes the damaged sprinkler head from the riser and then replaces it with a new head that matches your system’s specifications. After repairs, the technician tests the entire system for proper function and adequate water pressure. 

4. Valve Malfunction

Faulty valves typically cause various zones in your irrigation system to stop working properly, leak, or have low pressure leading to uneven watering. Valves can fail because of damage from dirt, gravel, age, or debris in addition to ordinary wear and tear. Malfunctioning solenoids can also cause valves to stick open, or to fail to close.  

A valve failing to close can become an emergency in short order if the homeowner is out of town or unavailable to turn off the water.  Control valves are one of those components that you count on to work all day every day especially when the brutal Austin heat waves hit.  

American Irrigation Repair in Leander, TX, and surrounding areas irrigation can inspect all the system’s valves for issues with functionality or performance.  Rebuilding, replacing, reconnecting, or adjusting the damaged valves will often resolve the trouble. In some cases, electrical repairs, wire locating, or diagnostics are also necessary.

5. Water Pressure Problems

The low water pressure causes inadequate sprinkler coverage, while high water pressure causes misting, which also wastes water, leads to high water bills and fails to provide proper irrigation coverage.  

Technicians address pressure issues by adjusting irrigation regulators, changing nozzle flow rates, adjusting control valves, or installing pressure regulators. If these adjustments don’t solve the problem, the technician will look for blockages or leaks in the irrigation lines.

A Leaking Sprinkler Valve You Can’t Count On

If there is one thing in a sprinkler system that you want to be able to count on, it’s the lawn sprinkler valves.  When the Texas heat is blistering, and the lawn is struggling you need to be able to count on them to turn on and supply water to the sprinklers.  Put the control valves need to fire when you ask them to reliably and every time.

Toro Flo-pro, a Leaking Sprinkler Valve You Can’t Count On

Toro’s flo-pro valves were popular in the 90’s especially around the Austin area.  When American Irrigation started servicing irrigation systems we’d see these valves many times per week around the Austin, Round Rock, and Georgetown service areas.  They were common and during that time some contractors seemed to prefer them.

Why Should the Toro Flo-pro Sprinkler Valve Be Replaced?

There were a handful of issues with these particular valves.  I suspect they were trying to release something new and improved with the jar-type style valve being promoted as a quicker tool-free way to enhance the serviceability of control valves.  Honestly, jar top valves just aren’t necessary if you build a high-quality valve that doesn’t need to be serviced often.

A Poor Valve Solenoid Design

In continuation of the idea of easier servicing / easier on contractors, Toro used a proprietary solenoid on the valve that was sold as quicker to install and didn’t need wire splices to connect the wires.  The solenoid was like the push-to-insert light switches where they have a copper spring-type conductor that is supposed to hold the wire and contact it.  Contact with the wire was iffy at best, and removing the wire from the solenoid would easily damage it or make it difficult to reconnect.

Later versions of the control valve were manufactured with an improved solenoid more like those sold today, however, the other issues with the valve remained.

Prone to Leaks

It was not uncommon to see the jar top threads work their way loose over the cycles.  American Irrigation Repair responded to calls finding a dead dying lawn with green dots where the flo pro valves were located.  The top of the bonnet would loosen over time causing the control valve to leak.  Often the leak would start small – roots would search out the water and you would end up with a control valve in the middle of a big wad of muddy root ball.

The Valve Diaphragms Were Notorious For failing.

The diaphragms would fail resulting in a no-open condition.  The marker for a failed diaphragm was that you could open the control valve from the controller and the solenoid would trigger but the valve would not open.  Most of the time the valve would hiss, you could hear it was trying to open.  This was caused by the bleed opening on the diaphragm becoming oversized which prevented the solenoid from being able to bleed enough water from the top of the diaphragm to open the valve.

Grouping of the valves with the later improved solenoid:

Hunter and Rain-Bird Control Valves Have Raised the Bar

If you have toro flo-pro valves in your system, I wouldn’t necessarily replace them if they are working correctly.  Once they act up or if you see any signs of leakage you should consider replacing them with a Rain Bird DV valve, or Hunter PGV control valves which have proven to be solid reliable performers.

Heatwave Irrigation System Strategies

Living in Austin, Texas, can often mean heatwave alerts. When those sweltering temperatures arrive, everyone wants to avoid the sun as much as possible, but residents aren’t the only ones feeling the heat – lawns suffer serious dehydration, too.

Do you know what to do to keep your Austin lawn looking lush green during a heatwave? In this post, American Irrigation Repair’s lawn experts look at a viable heatwave irrigation system that anyone can easily implement.

Water Your Grass Early in the Day

Watering your grass during the peak of the day’s heat might feel like the reasonable thing to do during a heatwave, but watering on a hot summer afternoon simply wastes water. You might drop the garden hose and pat yourself on the back for a job well done. However, the bulk of that liquid will evaporate so quickly there will be next to nothing left for the thirsty roots across your lawn.

The best time to water your lawn during a heat wave is just before sunrise. Aim to complete your watering schedule before the sun comes up.

Avoid Watering Your Grass Every Day

It may sound like a good idea to water your lawn every day during a heatwave. However, doing so will only lead to plants developing shallow roots. This makes the lawn and garden far less resilient to the heatwave (and any subsequent ones).

It’s always better to water deeper, longer, and less frequently during heatwave conditions. This strategy will force the roots of your grass deeper into the soil, making it all healthier.

Find the Perfect Watering Duration for Your Lawn

Often, people seeking advice on a heatwave irrigation system expect to find one-size-fits-all recommendations on how long to water a lawn during a heat wave. Unfortunately, there’s no such thing. The watering duration depends on a long list of factors, including: 

  • Soil type.
  • Vegetation.
  • The configuration of your landscape.

For example, you can water clay soil for just 15 minutes and have great results, while sandy soil needs 60 minutes to do the same. The wisest approach here is to speak to a qualified irrigation expert in Austin for a professional assessment and some tips.

Invest in a Smart Sprinkler System

Do you want a more long-term lawn solution that doesn’t involve some manual labor on your part? Consider installing a smart sprinkler system. Your heatwave irrigation system will be straightforward with a sprinkler setup that can adjust watering schedules based on the weather conditions and the specific needs of your plants.

Smart sprinkler systems reduce the risk of water wastage during a drought via accurate automation. Efficiency is highest with systems designed to monitor soil moisture levels.

Fixing a Sprinkler Head That Won’t Rotate

Will a malfunctioning sprinkler head adversely affect your irrigation system efficiency? Absolutely. When your system fails to distribute water evenly, it leads to overwatering in some areas and heat stress in others, so you’ll want to move quickly if a sprinkler head has suddenly stopped rotating as it did before.

If you’d like some tips on how to get your sprinkler system back to peak performance, read on for some information from American Irrigation Repair sprinkler head troubleshooting.

Common Causes of a Non-Rotating Sprinkler Head

Understanding the possible causes of a malfunctioning sprinkler head is the first step in addressing it effectively. Here are the most common reasons a sprinkler might stop rotating.

Debris Buildup

Over time, dirt, sand, and general yard debris can clog and disrupt a sprinkler head’s internal mechanisms and stop it from rotating smoothly. 

One solution is regularly cleaning each of the sprinkler heads. Filters are also a preventative measure against buildup that can lead to irrigation system failure.

Water Pressure Problems 

Your sprinkler system relies on consistent and sufficient water pressure to operate correctly. When water pressure drops, sprinkler heads often do not have sufficient force to rotate. Excessive pressure also causes parts to wear out prematurely or break unexpectedly.

The main concern is thermal expansion and high water temperatures during summer. Both of these things affect the pressure inside the sprinkler system. Malfunctioning sprinkler heads can also sometimes indicate underlying water pressure issues, so don’t wait too long to schedule a professional inspection.

Obstructions Around the Sprinkler Head 

Intuitively, physical obstructions like gravel, plants, or broken ground can also impede the movement of your system’s sprinkler heads. Have small, hard objects worked their way into the moving parts? 

Excessive sprinkler head stress like this will stop the rotation and cause lasting damage. If a sprinkler head won’t move, take it as an opportunity. Being proactive about scheduling repairs early restores the sprinklers’ function before things get expensive.

Misalignment or Damaged Parts 

Normal wear and tear catches up with all mechanical devices. Has your yard’s sprinkler heads become misaligned or damaged? 

The sprinkler head components that commonly wear out include: 

  • Gears.
  • Trip collars.
  • Trip pins.

How To Repair a Sprinkler Head That Won’t Rotate

Here are some basic troubleshooting steps to address a sprinkler head malfunction.

Clean Out the Sprinkler Head 

A sprinkler professional will begin by unscrewing the sprinkler head and rinsing it thoroughly under clean water. A small brush or pin removes debris from the nozzle and filter. After the thorough cleaning and reassembly, it’s also important to test that the sprinkler now rotates.

Adjust the Water Pressure 

The second check will be using a pressure gauge to measure the water pressure in your irrigation system – the ideal result is slightly higher than inside your home, at between 50 and 60 PSI. Low pressure could indicate leaks or problems with cut-off valves or backflow valves, whereas pressure that is too high might need a water pressure regulator repair.

Remove All Obstructions 

Is the area around the sprinkler head free of obstacles like pebbles, rocks, plants, or debris? Any of these items could block the sprinkler head’s movement. 

The sprinkler head should also be a level surface or platform to provide proper alignment.

Inspect for Damage or Misalignment 

Experts will then carefully inspect the sprinkler head for any signs of wear, misalignment, or breakage, paying particularly close attention to the gears, trip collars, and trip pins. If they detect any damaged or misaligned parts, sprinkler repair teams generally adjust or replace these as necessary. The sprinkler head must also correctly align to promote proper rotation. 

A non-rotating sprinkler head might come right with a few tweaks, but getting professional help on this ensures you don’t miss anything important. You might save a lot of money and aggravation on catching complex issues early.

Why Do My Sprinklers Have Low Water Pressure?

If you’ve noticed that your sprinklers have low water pressure, you may have shrugged it off as an anomaly. Many homeowners in Georgetown, Round Rock, Austin, and the surrounding areas are surprised to learn that this is a common experience. They’re even more surprised to learn that the solutions to this frustrating problem are often simple.

Persistently low water pressure in your property’s sprinkler system leads to insufficient coverage, leaving some areas completely dry and others waterlogged. A common cause of low pressure in irrigation is a system leak, which can also lead to substantial property damage if not addressed quickly. You won’t want to wait long to sort out your sprinklers.

Read on tips and tricks from the Georgetown sprinkler repair experts at American Irrigation Repair.

Common Causes of Low Water Pressure in Sprinklers

Several reasons could explain why your property’s sprinklers are struggling with low water pressure. Here are the most common issues our sprinkler repair crew encounters in the field.

Backflow Preventer Valve or Pressure Regulator Issues

Do your sprinklers have low water pressure, yet the pressure inside your home appears normal? There could be an issue with the valves in your system’s backflow preventer device. 

Backflow Valves

The backflow preventer stops water from flowing backward and out of your sprinkler into the water supply. It usually has two pipes: one horizontal and one vertical, each with a valve. These valves must be completely open to allow sufficient water flow into your sprinkler system.

The experts will check if the valves are fully open – the handles should be parallel to the pipes. This simple fix can often restore the proper water flow to your sprinkler system. 

Pressure Regulator

The irrigation system’s pressure regulator controls the water pressure flowing from each of the sprinkler heads to ensure consistency. When this component malfunctions, you will see fluctuating pressure – some sprinklers spray further than others. You might also hear some unusual sounds, like the squealing or sputtering associated with varying pressure levels.

You’ll want to contact a professional to adjust the valves or check the pressure regulator to ensure the sprinkler repair goes off without a hitch.

Main Water Valve or Shut-Off Valve Not Fully Open

Has anyone had a reason to close the main water supply to your property recently? When sprinklers have low water pressure, you may have an issue with partially closed main water valves and shut-off valves. While the resulting restriction in flow may not adversely affect household fixtures, like water-dependent appliances or the shower, it usually impairs sprinkler performance. 

Your sprinkler system requires a consistent water flow to operate, especially when compared to household appliances that only use water every now and then. Experts will troubleshoot a pressure problem by locating the shut-off valve that serves your sprinkler system. It must be fully open.

Leaks or Breaks in the Water Line

Are you noticing your sprinklers have low water pressure? You might want a professional to inspect your entire sprinkler system for problems beyond closed valves. One more serious scenario could be leaking water lines or burst pipes, which cause a substantial drop in water pressure downstream of the fault. 

It doesn’t take heavy equipment to damage a water line, although that is certainly a common cause of sprinkler system damage. Sometimes, something seemingly insignificant, such as installing a garden stake or a trellis, can puncture or rip a sprinkler line. To detect a leak, look around your yard for:

  • Unusual depressions.
  • Wet areas of soil or vegetation.
  • Lush growth that shouldn’t be there.
  • Water bubbling up from the ground when the sprinkler system is operating. 

If some sprinkler heads work properly while others do not, there could likely be a leak in the pipes between the heads. Wherever the problem lies, you’ll want to leave this repair work to experienced professionals to avoid doing more damage.

Obstruction of Water Lines

Sometimes, sprinklers have low water pressure due to an obstruction in the water line rather than an outright leak. For example, tree roots wrap around or pierce underground lines to restrict the normal water flow. Heavy objects depressing the soil over water lines, such as parking vehicles above them, also affect the pressure in the pipes and connections.

Obstructions can restrict water flow, which will significantly reduce the pressure in your sprinkler system. A professional repair service might replace the pipe, remove obstructions, or even reroute the damaged line and flush it to restore proper water flow.  

Clogged Nozzles or Dirty Sprinkler Heads

Clogged or dirty sprinkler heads and nozzles are another common reason for low water pressure. If the issue only affects one or two sprinkler heads, dirt or debris may block them. Of course, this stops the free flow of water, which will certainly produce a noticeable pressure drop in your irrigation system.

A professional like American Irrigation Repair will inspect and clean each of the system’s sprinkler heads and nozzles. If you spot excess grass or weeds around the base of sprinkler heads, you’ll want to clear them – obstacles like this stop sprinkler heads from popping up.

Increased Demand on Municipal Water Supply

Sometimes, sprinklers have low water pressure due to municipal water supply issues. Are your neighbors also experiencing low water pressure? 

If you notice the pressure drops during peak watering times, check the local water supply or contact your water supplier to be sure.
