Hello Sprinklerforum, I am sure this topic has been exhausted in the past, but I did not find a definitive answer anywhere. Does anybody still make an exhauster for Dry Sprinkler systems. We are having issues whit a system installed many years ago. Water delivery is 4-5 minutes to the inspectors test.
System starts out in building A as a 6" runs across the building feeding sprinklers in it, Then drops 12 feet to go underground 25 feet to building B and comes back up. This pipe underground is holding water. Open Inspectors test and it is 2 minutes before you start to see the sir gauge at the riser start to drop. We have written it up on inspections for years as too long of a trip time and the AHJ never said anything to our customer so they would get it fixed. NOW the AHJ will not let a remolded store open because the trip time is too long. The AHJ also "insisted" they install a waterflow switch for this space, NOW it had a Vane type switch on the dry pipe. -- Best regards, Charles mailto:[email protected] _______________________________________________ Sprinklerforum mailing list [email protected] http://lists.firesprinkler.org/listinfo.cgi/sprinklerforum-firesprinkler.org
