Ron, I too have attached my response to the "check valve on standpipes" question from a couple of weeks ago. I have to agree with the esteemed Mr. Leyton, if we are going to take the time to write, you should be taking notes. Much love,
Cecil Bilbo Academy of Fire Sprinkler Technology Champaign, IL 217-363-2460 www.sprinkleracademy.com My nature sorts with my vocation, Francis Bacon is pretty sure that I am happy. Brad and Damien, The new requirement for the check valve tracks with the NFPA 14 committee's desire to see one there. they had good reasons, because any water left in a system is a good thing for a couple of reasons. One, it will allow SOEMTHING to come out if there is a fire while the system is closed. Second, you wouldn't have to fill every floor of the building if you drained the entire building (and you wouldn't have to close each floor's control valve. That is a good thing. And if you don't have to clase a valve on each floor, then you won't forget to open one either. The 13 Committee was offended that the NFPA 14 Committee was trying to place a check on the Sprinkler System. (Tongue in Cheek....) But they eventually relented and agreed.
