The pressure relief valves are used in domestic water systems to protect hot water storage heaters. They combine different components with the following functions: • Safety function to prevent the pressure of the water in the storage heaters reaching dangerous levels. • Backflow prevention to prevent hot water return into the cold water mains supply – the check-valve can be controlled with a special gauge port, • A shut-off function to isolate the mains supply for maintenance or inspection of the heater system, • To drain the storage water heater: draining is ensured by the relief valve which can be actuated manually. Once opened pressurised water contained in the storage heater is evacuated.
