Check valve failure, so that the sprinkler leg is no longer isolated? -----Original Message----- From: Sprinklerforum [mailto:[email protected]] On Behalf Of Barry Levine Sent: Wednesday, October 12, 2016 1:01 AM To: [email protected] Subject: Seeking false water flow alarm suggestions
I drained all the water from my pipes when I installed a new water filter/softener system in my home. After installing the new system, which replaced some 3/4" pipe with 1" pipe in my home water system, I have been getting false alarms from my Potter Electric Signal Co VS-SP flow sensor. I flushed my sprinkler system using the drain and the test valve, yet I believe some air pockets may still remain in my two areas of coffered ceilings, where the sprinklers sit 1 foot above the rest of the system. Potter recommends replacing the VS-SP with a VSR-ST. I'd prefer not spending the money to replace the sensor, but I'd like to hear from the professionals before I make that decision. I'm thinking there may be other solutions, especially since I never had any false alarms during the previous 20+ years. Possibly I could attach saddle valves between each of the two sprinklers in the two coffered ceilings and bleed the air out. Unfortunately, I've never had any long-term luck with saddl e valves, as they have all become inoperative over time. I've attached a photo of my water system in case that might be helpful. Feel free to ask any questions or offer any solutions. Thank you. _______________________________________________ Sprinklerforum mailing list [email protected] http://lists.firesprinkler.org/listinfo.cgi/sprinklerforum-firesprinkler.org
