Diagnosing Sprinkler Valve Problems
A sprinkler valve is like the heart of your irrigation system. It controls the flow of water to different zones in your lawn, and when it starts to malfunction, things can get out of whack fast—too much water in one spot, not enough in another, or none at all.
If your water bill is suddenly sky-high or your sprinkler system is acting strange, the valve could be the culprit.
What are the signs of a broken sprinkler valve?
Here’s what we often see when we’re out diagnosing issues:
- One or more sprinkler zones don’t turn on.
- Water keeps flowing even after the system is supposed to shut off.
- Sprinkler heads are dribbling or leaking constantly.
- Dry patches in the lawn despite regular watering.
- An unexplained spike in your monthly water bill.
Why is only one zone of my sprinkler system not working?
This one comes up a lot in Indianapolis homes with aging irrigation systems. If just one section of your lawn isn’t getting water, odds are the valve controlling that zone is either clogged, stuck, or has an electrical issue.
Sometimes, it’s just a bad solenoid—the little part of the valve that opens and closes it. Other times, dirt or debris can block the nozzle or sprinkler head, making it seem like the whole zone is broken.
Can a sprinkler valve leak even if it’s off?
Yes—and we see it more than you’d think.
If the valve’s seal is worn or there’s damage inside, water can seep through even when the system is turned off. That slow leak may not be noticeable at first, but over time, it can cause soggy spots in your lawn and even backflow issues that mess with the rest of your irrigation system.
“We had a customer call in thinking it was just a clogged sprinkler head. Turned out, the valve was leaking water overnight and slowly eroding their lawn. By the time we got there, we had to do both a valve replacement and a little landscape repair.”
What happens if a sprinkler valve solenoid fails?
The solenoid is the brain of the valve. If it fails, your sprinkler valve won’t open or close when it’s supposed to—simple as that. That means:
- A zone won’t turn on when scheduled.
- Water runs constantly or doesn’t run at all.
- The system may short out or skip that section entirely.
It’s a fairly common sprinkler repair, especially in older irrigation systems around the Indianapolis area that haven’t been updated in a while. The good news? Solenoids are usually easy for our team to swap out, especially if you catch the issue early.
How do I test if my sprinkler valve is getting power?
First, make sure your irrigation controller is working right. Then:
- Use a multimeter to test the wires leading to the valve solenoid.
- Look for a voltage between 24–28 volts AC.
- If there’s no power, it could be a broken wire or a faulty controller.
“A lot of times, it’s not the valve—it’s the wire,” explains one of our experienced techs. “We’ve had calls where everything looked fine above ground, but the wiring had corroded underground. Once we found the bad spot, the fix was quick.”
I noticed that my sprinklers weren’t turning on at all, even though the irrigation controller seemed to be working. I was confused because everything looked fine above ground, but the lawn in my backyard on Brookstone Drive in Indianapolis was staying dry.
I called Warweg & Co., Inc. to help figure out the issue. One of their techs explained that sometimes it’s not the valve itself, but the wiring that causes the problem.
They used a multimeter to test the wires leading to the valve solenoid and found that the wire had corroded underground, which was blocking the power.
Once they fixed the bad section of the wire, the sprinklers started working perfectly again. It was a quick and easy fix thanks to their expertise! – Linda, Brookstone Drive, Indianapolis, IN.
Repairing Sprinkler Systems in Indianapolis
How much does sprinkler valve repair cost in Indianapolis?
The cost can vary depending on the issue, but here’s a quick breakdown:
- Basic sprinkler valve repair usually runs $85–$150 per valve.
- Replacing a valve could be $150–$250, depending on the setup and location.
- System inspection + diagnostics: around $75–$100, often waived if you go ahead with the repair.
How long does a sprinkler valve repair take?
Most valve repairs can be knocked out in 1 to 2 hours, tops.
Of course, that depends on a few things, like how easy it is to access the valve box (we’ve found some buried under 3 inches of grass) or whether the wiring is intact. If we’re doing multiple valve replacements or upgrading your system as part of a larger lawn sprinkler service, it might take a bit longer.

How often should sprinkler systems be inspected in Indiana?
In Indiana, with our ever-changing weather and seasonal shifts, we recommend inspecting your irrigation system at least twice a year:
- Spring (before first use): Check for freeze damage, broken heads, and valve function.
- Fall (before winter): Winterize the system, check the backflow preventer, and shut it down properly.
What causes sprinkler valves to go bad?
Great question—and it’s one we get asked all the time during sprinkler repair visits.
Here are the most common culprits behind failing sprinkler valves:
- Age and wear – Like any mechanical part, valves wear out over time.
- Dirt and debris – Sediment can clog up the valve or damage internal seals.
- Electrical issues – A faulty wire or bad solenoid can keep the valve from opening or closing.
- Water pressure problems – High pressure can stress your system and cause internal valve damage.
- Freezing temps – Water left in the system over winter can freeze and crack the valve housing.
“We once found a valve filled with ants,” one tech laughed. “They’d built a little home inside. Safe to say, the water didn’t flow quite right.”
Routine checks and professional irrigation service can help catch these issues early and keep your system from calling it quits at the worst time.
Last summer, I started noticing that my sprinklers on Maplewood Drive in Indianapolis weren’t functioning properly. The water pressure seemed off, and certain areas of the lawn were staying dry, despite running the system. After a quick check, I realized something was wrong with one of the valves.
I called Warweg & Co., Inc. for help, and their team quickly identified the issue: the valve had worn out over time, and there was some dirt and debris clogging it up. They also explained that high water pressure and potential freezing during the winter could have contributed to the problem.
After they replaced the faulty valve and cleaned out the system, my sprinklers were back to working perfectly. Warweg & Co., Inc., made sure everything was running smoothly, saving my lawn from more damage. – Rachel, Maplewood Drive, Indianapolis, IN.
