Pressure relief valves, sometimes known as PRV’s, Expansion relief valves or safety valves are designed to protect unvented hot water systems from over pressure caused by failure of pressure reducing valves, failure of expansion vessels or loss of internal air bubbles in system tanks. They are a vital component of the safety mechanism on a pressurised heating system so should never be disconnected or removed unless they are to be replaced immediately and should be serviced and maintained on an annual basis.
