Doug, Just to clarify:
This is a remote FDC? The cement covered pipe is the underground run from the building to the remote FDC? The problem is water leaking out of the FDC hose connections? Also: Why did you drill a hole in the cement covered pipe? Matt Grisé PE*, LEED AP Sales Engineer Alliance Fire Protection *Licensed in KS & MO 913.888.0647 ph 913.888.0618 f 913.927.0222 cell www.

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) _______________________________________________ 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)
