Question
I've recently replaced the control box, the wiring to the solenoid and the
solenoid.  Now, I can verify that the control box is working (only 1 zone ... it's
in an atrium), but only a drizzle of water comes out of one of the 6-8 spray
heads.  Prior to replacing the solenoid, the control box was faulty, but I could
still get a good flow out of all spray heads by turning on the faucet.  What am
I missing?  Thanks, Steve

Answer
Hey Steve, I hope this helps. It sounds like the diaphram in the valve, might be faulty. The other thing, could be the solenoid. Do you still  have the old solenoid? The first thing I would try, would be to put the old solenoid back on the valve, and see if it works with the old solenoid. If it doesn't, then I would suggest replacing the diaphram. The other thing to try, is when you turn the water off to the valve, take off the solenoid, then turn the water back on(with the solenoid off) and see if you have good pressure. If you do have good pressure, then you have a faulty diaphram. A good website to show you how to replace a diaphram is: www.irrigationtutorials.com. Try this out and let me know if I can be of anymore assistance. Thanks and have a good day.
