I have a situation where I need a Reduce Pressure Principal Backflow Prevention Assembly to meet a maximum operating pressure of 235 psi. The agency standards require a RP not a double check. The problem is most of the common manufacturers all have told me no one makes one rated for that high of pressure. They all top out at 175 psi operating pressure. The situation I have does not allow for a pressure reducing valve. Any one run into this problem before?
