Typical Installation Capacity <br /> Reduced pressure zone assemblies should be installed with <br /> minimum clearance of 12" between relief valve discharge port kPa psi 37; <br /> and floor or grade.They must be installed where discharge is not 138 20 <br /> objectionable and can be positively drained away.They should 103 15 <br /> be installed where easily accessible for testing and maintenance 69 10 <br /> and must be protected from freezing.Thermal water expansion <br /> and/or water hammer downstream of the backflow preventer 34 5 <br /> can cause excessive pressure. Excessive pressure situations 0 5 10 15 20 25 30 gpm <br /> should be eliminated to avoid possible damage to the system 0 19 38 57 76 95 114 Ipm <br /> and assembly. 1.5 2.3 3.0i a 6 mps <br /> kPa psi 1 <br /> 138 20 <br /> Refer to local codes for specific installation requirements.
