The boiler pressure relief valve is a safety valve designed to relieved an excessive build up of pressure inside the boiler. The is a pressure vessel designed to handle a safe amount of pressure. If the pressure were to build up beyong the safety limitations as set forth by the design specifications the boiler system needs a safe way to vent the pressure to prevent an explosion. The boiler relief valve is this safe way to vent excessive dangerous pressures inside the boiler. Read more below.

This pressure safety relief valve is piped into a nipple on the side of a Burnham boiler. The boiler relief valve also is piped to a drain so if the relief valve were to relieve or let go it would vent all the hot water to safe place away from people or electrical circuits. As part of a preventive maintenance plan these valves should be checked for seeping or dripping. Any boiler safety relief valve found dripping or seeping should be replaced. Most residential and light commercial hot water boilers have safety relief valves that will vent at 30 psi.
