Watts 25AUB


A Water PRV and strainer shall be installed on the water service pipe near its entrance to the building where supply main pressure exceeds 60psi to reduce it to 50psi or lower. Sill cocks and
outside wall hydrants may be left on full main pressure at the option of the owner. Provision shall be made to permit the bypass flow of water around the valve back into the main when pressures, due to thermal expansion on the outlet side of the valve, exceed the pressure in the main. PRVs with built-in bypass checks and integral strainer are acceptable.
