    Diagnosing Pressure Relief Valve Leaks

    Several factors can lead to a leaking pressure relief valve. High water pressure in the system is a common cause, often resulting from a malfunctioning expansion vessel. Additionally, mineral buildup can corrode the valve, leading to leaks. Understanding these root causes helps in diagnosing the issue effectively.

    Step-by-Step Fix for Pressure Relief Valve

    Fixing a leaking pressure relief valve involves several straightforward steps. Begin by turning off the boiler and allowing it to cool. Then, check the pressure gauge to determine if the system pressure exceeds recommended levels. If it does, release excess pressure through the filling loop.

    1. Turn off the boiler and allow it to cool.

    2. Check the pressure gauge for excessive readings.

    3. Release excess pressure using the filling loop.

    4. Inspect the pressure relief valve for signs of wear or damage.

    5. Replace the valve if necessary.
