Ground water is unlikely, I would think the check valve is still the problem, is the check valve exposed or buried? Screwed or flanged? Maybe you can isolated the check and see if water is still getting into pipe. I used to know a guy name Doug Hicks, he had a banjo, lived in Florida!!!!!!!!

We replaced the FDC, removed the ClaVal 581 check valve and cleaned it. We drilled a 2" hole in a cement covered pipe and found one hole drilled is the life span of the hole saw. Drilling the pipe makes a horrible noise also. But we still have water being introduced into the underground pipe. The cement covered pipe screws into a 4 inch galvanized pipe that exits vertically from the ground. We could have a leaking 581 valve, we could have a leak in the pipe and are having ground water forced into the pipe. As usual, any and all suggestions are welcome. Someday, sometime, someone will ask a question. I will jump up and wave my hand in the air, shouting "ME, ME! I know the answer! Call on me!" Until then, everybody will just shake their head and mutter, 'Him again" _______________________________________________ Sprinklerforum mailing list [email protected] http://fireball.firesprinkler.org/mailman/listinfo/sprinklerforum For Technical Assistance, send an email to: [email protected] To Unsubscribe, send an email to:[email protected] (Put the word unsubscribe in the subject field) This email and any attached files are confidential and intended solely for the intended recipient(s).
