From: Sprinklerforum <sprinklerforum-boun...@lists.firesprinkler.org> On Behalf Of Tom Wellen Sent: Thursday, March 29, 2018 1:15 PM To: sprinklerforum@lists.firesprinkler.org Subject: Playpipe Pitot Pressures - Fire Pump Annual Tests In my insurance days, I seldom had the same pitot pressures from playpipes. The pressures would be the same on several but others would be 1 to 2 psi different. I'm seeing fire pump reports consistently showing all the same pitot pressures for all four to six playpipes. I'm questioning that based on my past experience. Is the same pressures on pitots that common? Tom Wellen
