Hoping someone can help with this. I installed two new Rainbird DVF valves with Rainbird drip kits (filter, pressure reg) downstream. Now, both valves are dripping VERY slowly from around the solenoid. If I stand and watch them, I can see a droplet form around the bottom of the solenoid, and then slowly run down onto the valve body. I have already checked the following: -- Shut off water, removed solenoids, inspected, flushed, reinstalled. -- Valves seem to operate fine when I turn them on and off manually (by turning solenoid or external bleed screw). -- The drip lines downstream do not seem to be leaking when valves are off, so I don't think valves are leaking when off (ie, torn diaphragm, etc.). Of course, at this low rate of drippage, I probably wouldn't be able to tell. The only thing I can think of is this: If I understand how these solenoids work, I guess it's possible the dripping water is actually backflow -- water flowing from the driplines back down against the valve -- and it is leaking out from around the solenoid. But it doesn't seem like the head pressure would be high enough to cause this -- the lines don't rise any higher than grade, valves are in a box about 6" below grade. By the way, I installed two other DVF valves on same system, for sprinkler circuits -- these do not seem to drip. Any idea why these solenoids would drip? That's very clearly the source of the drip. Thanks.
