How Does a Pressure Relief Valve Work on a Boiler

What does a pressure relief valve do in a boiler? PRVs, also sometimes known as safety release valves, are in place to prevent a buildup of pressure. The valve opens to release pressure when the level becomes too high, and closes again when the pressure has dropped to within a safe range.

How do I know if my pressure relief valve is bad?

  1. System Cannot Reach Pressure. If your system isn’t reaching pressure, this could be a sign of pressure relief valve failure. …
  2. System is Over Maximum Pressure. …
  3. Pressure Relief Valve is Leaking or Has No Pressure.

What happens when a pressure relief valve goes bad?

When the valves go bad they start to vent when the pressure is not at the danger level. This can be just dripping to a full blown spray. There is not an adjustment on a pressure relief valve. You will need to replace it if it is venting and leaking water.
