Specifications
A Water Pressure Reducing Valve and strainer shall be installed on the water service pipe near its entrance to the building where supply main pressure exceeds 60psi (413 kPa) to reduce it to 50psi (345 kPa) or lower. Provision shall be made to permit the bypass flow of water back through the valve into the main when pressures, due to thermal expansion on the outlet side of the valve, exceed the pressure in the main supply. Water pressure reducing valves with built-in bypass check valves and integral strainer will be acceptable. Approved valves shall comply with ASSE 1003, CSA B356 and IAPMO. Valve shall be a FEBCO Company Series PRV-2. * A water saving test program concluded that reducing the supply pressure from 80 50psi (551 346 kPa) resulted in a water savings of 30%. ** Note: The bypass feature will not prevent the pressure relief valve from opening on the hot water supply system with pressure above 150psi (10.3 bar).
