[Sprinklerforum] Re: Air venting

It sounds like an apartment building. If the floors above are CPVC systems, they wouldn’t require an air vent. I would argue the use of metal devices in the valve assembly does not constitute a metallic pipe system. Taylor Schumacher Security Fire Sprinkler 1

It is even more of an issue for this building, as the only air vent valve is provided on the garage level of a four story building. thank you all for the good and timely responses, *Ken Wagoner, SET* *Parsley Consulting 500 West Mechanic Street Harrisonville, Missouri 64701-2235* *Phone: (760)

The language in NFPA 13 is clear from my perspective.  One air release per wet sprinkler system.For example - A 50 story building with one wet sprinkler zone control assembly per floor would require 50 air release valves. JohnJohn August Denhardt, P.E.Vice-President Engineering and Technical

Hey Ken, As has already been stated by others, I believe the intent is to remove as much air from 'each wet system' as possible. 'System', in this case, is any piping network isolated from the rest of the upstream system by isolation valving be it a check valve or a shutoff valve. Support for
