Hydro-Rain HRA-100-FF-FC 1" ASV Auto Valve w/Flow

Not only must they must be rugged enough to provide continuous protection, but they have to do that in even the most punishing environments. The HRA series delivers the goods. Its advanced design incorporates an accessible commercial grade high heat resistant glass-filled lid and an atmospheric vacuum breaker to reduce the risk of backflow and contamination, meeting all ASSE, CSA and IAPMO standards.
