Sprinkler System Zone Wont Shut Off

     Before you call a sprinkler system service company for a zone that will not shut off, troubleshoot the problem first.  This can be a frustrating issue when you see the zone or zones watering long after they should have shut off.  It could be something a simple as a programming error, but you could also find that a mechanical error like a stuck valve or wire malfunction is occurring.

     The first thing you can do is shut off the entire system at the control panel OR at the main backflow control valve OR at the system emergency shutoff valve which we can install for you.  Whether your controller’s setting says “OFF”, “RAIN”, or “RAIN OFF”, by switching to that setting, you will shut the system off electrically.  If the water stops running, the issue was in programming, and re-programming the water schedule could fix the problem.

     If water still continues to run, then this is an indication that the issue is mechanical in nature.  At this point, you will need to go to the water source to shut the system off.  The easiest way to locate the main water cut off is to find the backflow control valve, which is usually near the street with a green lid just at ground level.

     Now that you’ve concluded that the problem is mechanical, it is best to call an irrigation specialist who can find the problem and promptly repair it.  You do not want the system to continue running because this could only worsen the issue, as large amounts of water would be wasted, your lawn could literally drown, or it can create a hazard much like a burst water main pipe.

     Troubleshooting a sprinkler system zone that just doesn’t want to shut off is quite easy.  And although the problem itself could seem enormous, you can save yourself an emergency service call by troubleshooting the control panel first.  If you find that the issue is a mechanical one, shut off the main water source and call a sprinkler service company.
