Does NFPA 13D require trapped air to be removed in a sprinkler system?
In the 2016 NFPA 13, Section 7.1.5, Air Venting - a single air vent for a sprinkler system, with a connection conforming to 8.16.6, shall be provided in each wet pipe system utilizing metallic pipe.
I am using CPVC with anti-freeze in most residential systems.
Is there a code requirement for a vent for what I'm doing?
Thanks in advance.
