You are at 184 at the floor? As long as the heads are more than 18 ft up you are good with 175 rating. Hard to get hps with sprinklers much under 18 ft high so you might be good.

Same question for a backflow preventer? I have looked at all the manufacturers data sheets and I don't see any, but as sure as I state categorically that there isn't any such animal, someone will say but what about XXX mfg. We have a job with a static of 184, residual of 122 and a flow of 1500, want to use CMDA K14.0 or 25.2, and would like the extra pressure.
