How to Fix a Leaking Boiler Pressure Relief Valve |

The pressure relief valve, also as known as a blow-off valve, is a vital component of a boiler. Without a properly working valve, dangerous levels of temperature and/or pressure may build up in a home's heating system. Extreme pressure within the system could cause the boiler or water lines to rupture.

About Furnaces

The ideal pressure in a given furnace is a trade off solution in which the sum of hot gas losses and the cool air infiltration is minimized. The optimum pressure for most of the furnaces is about + 0,10 to 0,50 mm H2O measured at hearth level. This value must be determined through smoke testing in the furnace

How do I adjust my boiler pressure properly?

The pressure gauge needle indicates the actual pressure of the system. A green zone shows the correct pressure range, while a red zone shows the critical zone.: A red needle serves as a marker, while a black needle corresponds to the actual pressure.These two needles should be on top of one other.: In some boiler models, the water pressure is given by indicator lights on the control panel.
