How to Repair a Stuck Sprinkler Valve
A sprinkler valve can become stuck due to age, damage or if it is regularly exposed to the elements. By following a few simple steps, a stuck valve can be easily fixed. The only tool you will need is a small cloth.
Step 1 – Turn the Water Off
Make sure to turn the water supply off to prevent any water pressure build up which can damage your sprinkler system.
Step 2 – Find the Valve
A valve looks like a thin cylinder with a wire at each end. To release the valve, turn the valve to the left until it is released. To open the valve itself, turn the top of the valve until it opens. Remove the spring and flexible diaphragm within the valve.
Step 3 – Clean the Diaphragm
Using the small cloth, wipe away any dirt from the diaphragm. Also clean the valve and the housing. If there is damage to the spring or the diaphragm, you will need to replace these parts.
Step 4 – Reassemble the Sprinkler Valve
Twist the valve housing back together and return the valve to the sprinkler head, turning right to tighten. Turn the water supply back on to test if the valve is working properly.
