Brass slimline double check valve for Fluid Category 3 contamination risks

Reliance Valves Floguard Double Check Valves protect against the risk of backflow and back siphonage contamination. The compact and lightweight valves are ideal for all class 3 contamination risks as per Water Supply (Water Fittings) Regulations 1999.

Double check valves contain two valves so that if one valve fails, the other acts to prevent backflow and contamination in the mains water supply. The valves contain a check cartridge that under normal conditions is held closed by pressure within the system. When vacuum conditions occur, the suction causes the check cartridge to open and air to flow through, equalising the pressure within the hot water heater.
