Every year, we head out to hundreds of properties across Central Texas to get sprinkler systems ready for the watering season ahead. What we find is rarely dramatic. Most systems don’t need an overhaul. They just need the small stuff caught and corrected before the Texas heat turns a minor issue into a major one. Here’s a rundown of what we run into most and why it’s worth paying attention to even when a problem seems small.

The Sprinkler System Issues We Find Most Often

Ranked from most to least common, here’s what our team typically finds during a tune-up.

1. Broken Heads

This is the most common issue by far, and it’s often the easiest to spot. A cracked or snapped head usually shows up fast, either as a geyser when the system runs or as a dry patch where water should be landing.

2. A Broken Lateral Pipe

This cuts off water supply to one or more heads and can be harder to diagnose without digging. Unlike a broken head, there’s often no obvious visual clue above ground, so a soggy patch of lawn or a zone that just won’t pressurize is usually the first sign something’s wrong underneath.

3. Control Valves Not Opening Correctly

A valve that won’t open means a whole zone can go without water, sometimes for weeks before anyone notices. These issues can come from debris caught in the valve, a wiring problem, or a solenoid that’s simply worn out.

4. Buried Heads, or Heads at the Wrong Height

If a head isn’t sitting at the right height for the area it covers, it can’t do its job. Heads settle over time, get buried under mulch or soil buildup, or end up too low or too high after landscaping work, and any of those throws off coverage even when the head itself is working fine.

5. Heads Modified With Larger Nozzles

Sometimes a previous repair installs a nozzle with a higher flow rate than the water meter can actually supply. It might look like an upgrade, but if the system can’t keep up with the demand, it usually just means weaker pressure across the rest of the zone.

6. Pressure Regulator Issues

The pressure regulator on the water meter or plumbing supply feeding the irrigation system can cause problems, too. A loud, vibrating, or hissing sound when the system runs is often the first sign, and this one usually needs a professional to diagnose since it involves the plumbing supply rather than the sprinkler components themselves.

7. Debris in the Water Meter

This happens more often than you’d think. If your system worked fine last year and won’t come on this year, this is a good place to look, since sediment or debris can build up gradually and eventually block flow enough to stop a zone from running at all.

8. Mower and Weed-Eater Damage

Sprinkler heads and lawn mowers have been fighting each other since the beginning of suburban irrigation, and the mower almost always wins. If you’re seeing this often on your system, check that your heads are cycling up and down correctly. 

The most common cause of mower strikes is actually heads that aren’t lowering when they turn off, or heads that were installed too high in the first place. No component of an irrigation system should sit high enough to get hit while the system is off. If a head is worn out, it tends to stick up more, so if you’re seeing several heads sticking up, that’s a sign it may be time to replace them. Replacing them all at once can make a noticeable difference in how reliable the system is going forward.

9. Leaks

These are sometimes obvious, but not always. A leak at a fitting or valve can show up as an obvious puddle, but plenty of leaks stay hidden underground for a long time, quietly driving up a water bill before anyone spots a problem on the surface.

10. Controller Issues

One thing many homeowners overlook is the sprinkler controller itself. Controllers are basically the brain of the irrigation system, but every year, we find timers still set to winter schedules, outdated watering days, or run times that don’t match current weather conditions. Some controllers lose their settings after a power outage or freeze, while others get reprogrammed incorrectly. Your annual sprinkler tune-up should include a review of start times, watering duration, rain sensor operation, and scheduling for current temperatures, as well as seasonal adjustments. 

Small Fixes That Make a Big Difference

Some of the issues we find aren’t dramatic. A head might be leaning slightly, or it might just barely clear the grass after mowing. We understand not wanting to spend the money or deal with the digging that some of these fixes require, and we hear “the heads are working fine” a lot. But with sprinklers, small tweaks can substantially improve coverage:

• Leaning or low heads: Straightening a leaning head or raising one that’s sitting too low are two of the simplest adjustments that make a real difference in how evenly a system waters.
• Heads knocked out of alignment: Mowing crews or foot traffic bump heads out of position more often than people expect, and they’ll slowly start watering the sidewalk instead of the grass (and no, your concrete driveway will not widen because you keep watering it). 
• Unnecessary tree bubblers: That tree that’s been in the ground for twenty years and gets watered by the heads in the lawn doesn’t need a separate bubbler soaking its trunk, too. Once a tree is well established, that bubbler can be capped, since the water already reaching it from the lawn heads is more than enough.
• Low pressure: This is another issue that comes up regularly and is worth having a professional take a look at, since it can point to a problem well beyond the head itself.

Why Regular Tune-Ups Save Money

Many homeowners think sprinkler tune-ups are mainly about keeping grass green. Honestly, they’re just as much about avoiding water waste.

A single leaking valve or broken nozzle can waste an incredible amount of water over time. Because irrigation systems usually run early in the morning, many leaks go unnoticed for weeks. We’ve seen customers get water bills that looked more like truck payments because a hidden leak stayed active through the summer.

Small inefficiencies add up fast, too. A tilted sprinkler head might not seem like a big deal, but if it causes dry spots, homeowners often compensate by increasing run times across the whole system. That means the healthy areas get overwatered while the problem area still struggles, which leads to fungus, runoff, shallow roots, wasted water, and stressed lawns during the Texas heat. A properly adjusted irrigation system waters more evenly while using less water overall.

Signs Your Sprinkler System Needs Maintenance

When turning your system back on in the spring, here are a few signs it may need attention:

• Unusually high water bills
• Soggy areas in the lawn
• Dry or crunchy patches
• Low-pressure zones
• Sprinkler heads not popping up fully
• Water spraying onto concrete
• Zones that keep dripping after shutoff
• Inconsistent coverage
• Visible leaks around valves

Even small symptoms usually mean something underneath needs adjustment, and the earlier those issues are found, the easier they usually are to fix.

Final Thoughts

Most sprinkler systems don’t need a massive overhaul every year. Usually, they just need attention. A few adjustments here, a repaired head there, maybe a valve cleanup, a nozzle replacement, or a controller update. Those small corrections are what keep a system running efficiently through the brutal Texas summer ahead, because once July arrives in Central Texas, small irrigation problems tend to become very noticeable very fast.

Trust us, it’s a lot more fun finding a small leak during an annual tune-up than discovering it after your lawn starts crunching under your feet in August. That’s why yearly irrigation tune-ups remain one of the smartest preventative services homeowners can invest in.

February in Texas can be unpredictable. One week brings hard freezes, the next feels like spring. Even if your sprinkler system survived winter without obvious issues, freeze damage often shows up later, quietly and below the surface. That’s why it’s smart to take time now to check your sprinkler system for freeze damage before peak watering season begins.

This guide walks you through a practical, zone-by-zone sprinkler audit to help you spot leaks, pressure issues, and damaged components early. You can handle much of this inspection yourself, and if something doesn’t look right, you’ll know exactly when it’s time to call in a professional.

Why Freeze Damage Is Often Hard to Spot

Freeze damage doesn’t always announce itself with a broken head spraying water into the street. When water freezes inside pipes, valves, or fittings, it expands. That expansion can cause hairline cracks, weakened seals, or small splits underground.

Once temperatures rise and the system is pressurized again, those weak points may leak slowly rather than burst. The result is wasted water, reduced performance, and stressed landscaping that looks more like a lawn care problem than an irrigation issue. That’s why a post-freeze sprinkler audit matters, even if your system appears to be working.

A Step-by-Step Guide to Post-Freeze Sprinkler Leak Detection

Here are five DIY steps you can take to check your sprinkler system for freeze damage.

1. De-Winterize Your Sprinkler System in Texas

Before testing anything, make sure your system is fully out of winter mode.

Start by slowly turning the main water supply back on. Opening it too quickly can stress pipes and fittings that may already be compromised. Listen for unusual sounds and watch the meter if possible.

Next, set your controller to manual mode. You’ll want full control over each zone so you can test them individually without relying on programmed schedules.

If your system has an above-ground backflow preventer, visually inspect it before running water. Cracks, leaning assemblies, or moisture around the base can all be broken backflow preventer signs caused by freezing temperatures.

2. Perform a Zone-by-Zone Sprinkler Test

Running your system zone by zone is the best way to catch hidden problems early. Take your time with this step.

Turn on the first zone and let it run for a few minutes. Then, walk the entire area while it’s operating. 

Remember, you’re looking for more than obvious spray issues. Pay attention to sprinkler head performance. Heads should pop up fully and retract cleanly when the zone shuts off. Weak spray patterns, heads that don’t rise completely, or uneven coverage can indicate pressure loss from underground leaks.

Listen closely as well. Hissing or bubbling sounds often point to water escaping below the surface.

Repeat this process for every section in your system to spot a failing zone. Problems may only show up in one area, especially if freeze damage affected a single lateral line or fitting.

3. Assess for Subsurface Leaks

Subsurface leaks are one of the most common forms of freeze damage and the easiest to miss.

After running a zone, look for soggy spots that don’t dry out within a few hours. Grass that feels spongy underfoot or soil that stays dark and wet is a strong indicator of a leak below ground.

Watch for sinking soil or small depressions forming along sprinkler lines. These can develop as leaking water washes away soil. Another red flag is low pressure across an entire zone. If every head in a zone seems weaker than usual, the problem is often underground rather than at the head itself.

4. Check Valves and Zone Control

Freeze damage can affect sprinkler valves just as easily as pipes. As each zone turns on and off, confirm it responds immediately. Zones that won’t shut off completely or struggle to activate may have cracked valve bodies, damaged diaphragms, or compromised solenoids.

If a zone continues to run after the controller is off, that’s a clear sign something isn’t sealing correctly. This type of issue wastes significant water and should be addressed quickly.

Also check valve boxes for standing water or mud. Valve boxes should be dry inside. Persistent moisture often points to slow leaks that started during a freeze.

5. Inspect the Backflow Preventer

Backflow preventers are especially vulnerable during Texas freezes because they’re often above ground.

Look for visible cracks, corrosion, or fittings that appear misaligned. Water stains or mineral buildup around the device can also indicate slow leaks.

If you notice pressure fluctuations throughout the system or water pooling near the backflow assembly, stop testing and schedule professional service. Backflow issues affect both irrigation performance and water safety.

When a DIY Audit Isn’t Enough

A zone-by-zone audit helps you identify warning signs, but some freeze damage can’t be confirmed without professional tools.

Pressure testing, valve diagnostics, and advanced leak detection allow technicians to locate issues before they become major repairs. If you notice recurring soggy areas, unexplained pressure loss, valve failures, or broken backflow preventer signs, it’s time for a professional inspection.

Protect Your System Before the Texas Heat Returns

Texas weather doesn’t wait, and neither should sprinkler problems. A post-freeze sprinkler audit gives you peace of mind and helps ensure your system is ready for warmer days ahead.

If your DIY inspection raises questions or uncovers issues you’re unsure how to fix, professional help can make all the difference. A thorough inspection now keeps your lawn healthy, your water bills in check, and your irrigation system running efficiently all season long.

As the vibrant hues of summer fade and the crispness of fall settles in, it’s time to shift gears in your lawn care routine. While your sprinkler system worked overtime during the hot months, the cooler temperatures of fall require a different approach. Properly preparing your irrigation system now can ensure it continues to function efficiently and avoid costly repairs when spring arrives.

Why Fall Maintenance Matters

Neglecting your sprinkler system during the fall can lead to:

• Frozen Pipes: Water left in the system can freeze, causing pipes to burst.

• Inefficient Watering: Outdated settings can waste water and money.

• Spring Setbacks: Unaddressed issues can delay the start of your watering schedule.

By taking proactive steps now, you can safeguard your system and ensure your lawn remains healthy.

5 Essential Fall Maintenance Tasks

1. Adjust Watering Schedules

With cooler temperatures and reduced evaporation rates, your lawn’s water needs decrease. Adjust your sprinkler controller to water less frequently, typically once or twice a week, depending on rainfall. This adjustment prevents overwatering and promotes deep root growth.

2. Inspect and Clean Sprinkler Heads

Debris, dirt, and grass clippings can clog sprinkler heads, leading to uneven watering. Inspect each head for blockages and clean them thoroughly. If any heads are damaged or misaligned, replace or adjust them to ensure optimal coverage.

3. Check for Leaks

Even small leaks can waste significant amounts of water over time. Walk through your yard and observe the sprinkler zones for any signs of pooling water or soggy areas. Address any leaks promptly to prevent water waste and potential lawn damage.

4. Flush the System

Flushing your sprinkler system removes debris and mineral buildup, ensuring smooth operation. Run each zone for a few minutes to clear out any particles that might obstruct water flow.

5. Winterize the System

In regions where temperatures drop below freezing, it’s crucial to winterize your sprinkler system to prevent freezing and bursting pipes. This process involves draining all water from the system and insulating vulnerable components. It’s recommended to consult with a professional to ensure proper winterization.

Seasonal Checklist: Transitioning from Summer to Fall

To help you stay on track, here’s a handy checklist for fall sprinkler system maintenance:

• Adjust watering schedule to reduce frequency.

• Inspect and clean sprinkler heads for debris.

• Check for leaks and repair as needed.

• Flush the system to remove debris.

• Winterize the system if temperatures drop below freezing.

• Inspect backflow preventers for proper operation.

• Check and replace batteries in controllers if necessary.

• Review and adjust spray patterns to prevent overspray onto sidewalks or driveways.

Finding sprinkler lines can seem tricky, but there are effective ways to locate them without unnecessary digging. If you’re wondering how to find sprinkler lines without digging or need tips on how to find PVC sprinkler lines, tools like wire locators or electronic line tracers can help pinpoint their location with ease. For those trying to figure out how to find sprinkler heads or how to avoid sprinkler lines when digging, start by identifying the layout of your system, often guided by the location of valves or control boxes. In Travis, where irrigation is common, knowing how to find sprinkler lines in Texas can save time and prevent costly repairs. Using these methods ensures you avoid damaging your system while keeping your yard intact.

Why Locating Sprinkler Lines is Important

There are essential reasons behind seeking a precise location of the property’s underground sprinkler lines. For one thing, digging or installations on your property that interfere with your system’s lines can compress or puncture those lines, leading to expensive repairs and the risk of water damage.

It’s also helpful to immediately locate lines to remedy:

• Leaks.
• Water pressure problems.
• Maintenance or repair issues.

As experts like American Irrigation Repair will tell you, locating lines with precision is the first step to handling this sort of work efficiently. After all, causing unnecessary property damage is something everyone wants to avoid! 

Methods for Locating Sprinkler Lines

So, what are the methods professionals use to locate underground sprinkler system lines?

Check for a System Map

While it might seem obvious, the easiest method for quickly locating sprinkler lines is to refer to a system map. Installation companies often prepare a detailed map that shows the exact location of sprinkler heads and service lines. When properly drafted, these maps provide accurate measurements from building foundations, curbs, and fixed property markers.

Have you lost your system map? Are you unsure if you received one when you installed the system or when you bought the property? Try contacting the company that installed the system for a duplicate map. 

Look for Sprinkler Heads

Do you know how to find sprinkler lines? Well, lines always connect to sprinkler heads. In the absence of a map, the sprinkler heads’ locations provide you with great clues as to the location of any underground lines.

A technician might approach this process by marking the position of each sprinkler head to trace the approximate path between them. Installers usually run straight lines between each head, forming a grid (unless there are some obstructions or other reasons to deviate from straight lines). A grid formation is the most efficient distribution system, and you can easily mark these lines between sprinkler heads with flags or spray paint.

Find Valve Boxes

Valve boxes are another essential component of your property’s sprinkler system. The boxes house the valves that control water flow to each zone of your irrigation system. Installers usually place valve boxes close to buildings or sprinkler heads in a round lid mounted flush with the ground. 

When repair technicians locate a valve box, they can trace lines from valves to nearby sprinkler heads. (Some valve box designs place them below the surface, so you would carefully dig around it to expose the box without damaging the lines that connect to it).

Use a Line Tracer

As its name suggests, a line tracer is an electronic device that helps locate underground lines without extensive digging. Knowing how to find sprinkler lines with a tracer is quite simple: 

• You send an electronic signal through the wires that run alongside sprinkler lines. 
• A receiver picks up the signal.
• The tracer interprets the signal, indicating the precise path of the sprinkler lines.

This technology is helpful with older irrigation systems that lack a reliable system map.

Probe for Sprinkler Lines

Have you thought about using a probe to locate underground sprinkler lines? The probing tool enters the soil to feel for resistance from pipes buried under the surface.

It’s low-tech, and you must exercise caution to avoid damaging buried lines.

Ground Marking Techniques

One final technique is ground marking, a straightforward sprinkler line location method that involves digging around sprinkler heads or valve boxes to locate a section of the pipe. After the dig exposes a line, mark its path with flags or spray paint. 

This process is time-consuming. It requires a good bit of digging in precise locations, but it does offer certainty in your search for water lines.
