It Worked
One of my sprinkler valves stopped working correctly. It would not stop the flow of water when in the off position. I did some research on youtube and found that this issue was usually a result of a defective diaphragm. Replacing the diaphragm solved the problem, the valve now closes as expected.

When reinstalling the diaphragm does the pointed end face up with the spring on top of it?

BEST ANSWER: Sorry Can't tell you I have not used the part yet. Can you tell when you take the valve apart how the old diaphragm was installed?
I am looking for a replacement to the screw cap portion of a Rainbird JTV/AS-100 1" valve that is leaking. Do you carry that part?
A shopper on Oct 5, 2011
BEST ANSWER: The symptoms I had was with the zone valve electrically shut off, one of the sprinkler heads would rise and emit a stream of water about 10' and then as the pressure decreased, retract back into position. I diagnosed that as a leaking diaphragm. These guys had the diaphragm in stock, I ordered 2 and 2 solenoids. I changed the solenoid and diaphragm and voila ... problem solved.
I had not problem with a cracked cap. Your description sounds like you have diagnosed the problem as a crack in the cap. That was not my issue. These guys should the all the parts for those valves .... I am not in any way a profession irrigation guy, merely a handy homeowner ... and engineer by trade so I am used to diagnosing problems and solving them. Good luck to you, I know how frustrating some projects can be ..... Best ..... Abe
