Is there a BFP on system ? John Drucker - Mobile Email ----- Original Message ----- From: sprinklerforum-boun...@firesprinkler.org <sprinklerforum-boun...@firesprinkler.org> To: Sprinkler -Forum <sprinklerforum@firesprinkler.org> Sent: Wed Feb 20 06:55:16 2013 Subject: Flow switch problem
We have a wet system that is having problems with the flow switch. The flow switch would send a signal and then stop and then send another signal. This would be happening intermittently. We figured the flow switch diaphram was bad and then replaced the flow switch with the same results. The main drain test is 60 psi with 50 psi residual. The inspector's test was a globe valve that would flow water intermittantly; so we changed it to a ball valve. It flows water continuously now with the same problem with the flow switch. We checked the vane on the flow switch and the pipe is clean, so it's not hanging up at the riser. Any suggestions?
