![]() ![]() ![]() If you rip the diaphragm or find it damaged you can just go buy a new valve exactly matching what you have and put the new top on the old body. Be careful to not make things worse by getting more dirt into the valve when you do this.Ĥ) Assemble the valve the same way it came apart, be careful not to over tighten screws and strip out the body.ĥ) Turn water back on and check for leaks, if you put your ear right against the valve you can usually hear a small leak. You can also crack the upstream valve a bit and flush out the line upstream of the valves with the tops off. Pull out the diaphragm and rinse out the valve body, top and diaphragm with a hose and clean out any dirt. You can unscrew the solenoid from the valve top if necessary.ģ) Carefully observe the alignment of the diaphragm and spring inside the valve and make sure you don't get any more dirt inside the valve. 'Low Head Drainage' occurs when the lowest head on a zone allows water to drain from the lateral piping, out of the sprinkler. The most common reason is called Low Head Drainage. If your valve has screws holding the top on just undo the screws and lift the top off. There are two reasons why a sprinkler will leak water when the system is supposed to be off. Not difficult but just pay attention to how everything came apart and get it all back together properly.ġ) Shut off the water supply upstream of the valves and open a valve to bleed off the pressure.Ģ) If you have a Jar Top Type valve you can just grab the top of the valve ( that part that the solenoid screws into) and unscrew it off the valve body. Running the valves for a long time probably wont fix anything, you will need to take the top off the valve to do this. ![]()
