Does anyone know of a CMDA Extended coverage sprinkler rated above 175 psi? 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.
