10 common signs your sprinkler system is not working properly

1. Uneven or Dry Patches on Your Lawn

If parts of your lawn are brown or dry while others are green, it’s a sign that your sprinkler system isn’t distributing water evenly. This could be due to clogged nozzles, poor water pressure, or misaligned heads.

2. Low or No Water Pressure

Weak sprinkler streams or heads that barely pop up may indicate a leak in the line, a broken valve, or a pressure regulation issue.

3. Water Pooling or Soggy Areas

Puddles or soggy spots in your yard suggest overwatering or possible underground leaks. Over time, this can damage roots and promote mold or fungus.

4. Sprinkler Heads Not Popping Up or Staying Up

Heads that fail to rise or retract could be blocked by debris, damaged by lawn equipment, or have failing internal mechanisms.

5. Broken, Tilted, or Missing Sprinkler Heads

Physical damage is common from mowers, foot traffic, or freezing weather. A damaged head may leak water or spray erratically.

6. Unusual Noises

Hissing, banging, or gurgling sounds when the system runs often indicate air in the pipes, a malfunctioning valve, or a water hammer effect due to pressure issues.

7. Sprinklers Run at the Wrong Time

If your system runs during the day, when it’s raining, or outside of the scheduled time, there could be an issue with the controller, rain sensor, or wiring.

8. High Water Bills

A sudden spike in your water bill without any change in usage could point to leaks or overwatering from a malfunctioning controller or stuck valve.

9. Misting or Fogging Spray

If your sprinklers produce a fine mist instead of a steady stream, your pressure might be too high. This leads to water waste through evaporation.

10. Zones Not Activating

If one or more zones don’t turn on, it could be due to a faulty solenoid, a cut wire, or a controller issue.

What to Do If You Notice These Signs

Perform a system walkthrough and observe each zone while it’s running.
Check for visible leaks, clogged heads, and water pressure problems.
