Readers ask: Water Sprinkler Wont Stop When Turn On Water Supply?

Why are my sprinklers not turning off?

One of the most common reasons that a sprinkler zone won’t shut off has to do with debris stuck in the valve. This is especially the case if your sprinkler heads are located underground. The soil, rocks, and loose debris that surrounds the system could potential tamper with the solenoid.

Why do my sprinklers keep running?

More often than not, there will be a valve that is stuck in the “open” position on the pressurized system. When the valve remains open, water continues to run down the line, which causes your sprinkler to continuously run even when the timer is in the “off” position.

How do you fix a stuck sprinkler valve?

Here are some tips for valve repair.

  1. Turn the controller to ” System Off” so it does not try to cycle a program.
  2. Shut off the main water supply.
