Have you ever noticed that your sprinkler seems to keep running, even though the timer is turned off? Does the muddy mess that gets left behind when your sprinkler runs for too long frustrate you? If so, then it is time to put your frustrations aside with these helpful sprinkler system tips and tricks.

Determining The Cause For A Continuously Running Sprinkler

While it can be mind-boggling that a sprinkler will continue to run even though the timer is set to “off,” it is important to remember that an automatic irrigation system has a lot of moving parts. With this in mind, there are few steps that you can take to better determine why your sprinkler appears to be malfunctioning. 

Step 1: Determine if the problem is mechanical or electrical in nature.
To do this, check the main power supply. Turn off the circuit breaker or unplug it from the wall. Once you have completed this step, check to see if the sprinklers have either turned off completely or remained on. If the sprinklers have turned off, then you have identified that the issue lies with the timer. However, if the sprinklers continue to run, then the problem is mechanical in nature. 

Step 2: Identifying the mechanical issue.
If Step 1 didn’t resolve your sprinkler issue, then it is time to check the sprinkler system’s valve. 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.

Step 3: Repairing the electrical or mechanical issue.
Repairing an electrical issue will require you to determine if the issue is the controller, the wiring, or the valve’s solenoid. Depending on your mechanical issue, you will need to use a valve repair kit or just replace the faulty valve.
Through these three steps you should be able to resolve your sprinkler problem.
