To fix a leaking sprinkler valve, you’ll typically need repair parts such as a replacement diaphragm, O-rings, or a new solenoid. These parts address common causes of leaks and are available in sprinkler valve repair kits. It’s essential to match the parts with your specific valve model to ensure compatibility and a proper seal.
To use the Febco PVB Check Assembly Kit, first turn off the device’s water inlet valve. Next, open the test cocks and remove the bell, bonnet, poppet, spring and check valve. Once these parts are removed, insert the new check valve and reinsert the new PVB internal parts in the reverse order that you originally removed them. Lastly, open the inflow valve and close the test cocks.
The first step to repairing your fault diaphragm is to turn off the sprinkler water supply. Next, unscrew the valve bonnet from the valve body and remove the valve bonnet assembly and spring. Once the valve bonnet assembly and spring are extracted, gently pry the damaged diaphragm out of its seat and flush out the valve body and seat with clean water. After that, you’ll need to press in the new diaphragm and replace the spring and the valve bonnet. Finally, tighten the screws, turn on the water, and check for leaks.
