The patented Woodford RHY2-MS is intended for irrigation purposes and to provide water availability on commercial building roofs. Applications include window washing, cleaning of condenser coils, cooling towers and other types of roof equipment. The RHY2 is backflow protected with an ASSE 1052 double check backflow preventer that is field testable. The backflow device does not require removal for drain down. The RHY2 has a built in vent that allows drainage. Valve body of hydrant is drilled and tapped with …›″ drain hole which must be piped to a drain location. The RHY2-MS allows for installation flexibility since it is not necessary to install hydrant when the patented Mounting System is bolted to the roof.

All necessary mounting hardware for proper installation on a commercial roof is supplied, including a 2 degree shim for pitch adjustment.
