Troubleshooting: Why Won't My Sprinkler System Turn Off?
Overview
If your sprinkler system continues to run even when you've tried turning it off, you're likely dealing with one of several common issues. This guide will help you understand the problem and troubleshoot it step-by-step.
Common Causes
-
Broken or Stuck Valve:
Sprinkler valves control water flow to individual zones. A stuck or broken valve can keep water flowing continuously.
-
Controller Malfunction:
A faulty timer or controller may fail to signal the valves to shut off.
-
Valve Diaphragm Issues:
A damaged or sticking diaphragm inside the valve can prevent it from closing completely.
Troubleshooting Flowchart
-
Check Controller:
Confirm the controller is set to the "off" position. If the controller is off but water continues flowing, move to the next step.
-
Manual Valve Check:
Locate your sprinkler system valves and gently turn the valve solenoid clockwise to shut off manually. If the water stops, the valve or controller might be the issue.
-
Inspect Valve Components:
Turn off the water supply to your sprinkler system. Remove the valve cover and inspect the diaphragm and spring. Replace any parts that are damaged or worn.
-
Consult a Professional:
If these troubleshooting steps don’t resolve the issue, contact an irrigation professional for advanced diagnostics.
Preventative Maintenance Tips
- Inspect and clean valves periodically.
- Regularly test your controller and update schedules seasonally.
- Replace worn parts, such as valve diaphragms, promptly.
