Why is your Sprinkler valve not coming on?

The valve plays an important role in your sprinkler system, and it works perfectly fine when it is cared right. A Sprinkler valve can develop a problem like the water in the system is not shutting off, you need to check the controller and wires and see if they are okay. If yes, then the issue is with the valve itself.

Take a look at the most common problems you may encounter with your sprinkler valves.


Common Problems with Valves


Stuck Valve – The valve can get stick sometimes, usually, this is caused by rocks or debris preventing it from closing properly. Making it hard for the water to pass through the line and up to the sprinkler head resulting in your lawns dying.


Irregular watering – Uneven watering does not directly mean there is a problem with the sprinkler valves, there are other cases that can cause it. There are three possible causes you can use to distinguish the issue; one is you have attached the wrong head to the sprinkler valve. Two is the sprinkler valve is too far from each other, and lastly, is you have set a different schedule for other areas causing it to be confused.


Wiring – When your controller has been programmed correctly but the sprinkler valve won’t come on you need to inspect the wiring. Start looking at the connections one by one and see if there is corrosion.  If you have discovered one it needs to be cut away. If the sprinkler is still not working properly, it needs to be rewired and for that, you need to call in a professional.
