Thanks Jim. I won't quote the numbers of the case we recently heard about-- the sprinklers were way up there, under a metal deck, non-conditioned space, hot day, no pressure relief-- but I was pretty astounded at the increase in pressure above normal city static. Brad

I just wanted to say that if contractor's start venting practices on existing systems, through remote Insp. Test. Conn., aux. drains, ect, for piping in areas subject to high ambient temperature, it would be a good idea to make sure there is a 1/2" pressure relief valve. The 'air cushion idea' is not a myth!!
