    I have a Weil McLain Gold GCT boiler with an expansion tank and a separate hot water heater.

    My pressure relief valve isn't releasing pressure when the gauge reads 40 psi so I am going to replace it.

    The current valve is a watts m330-m1
    30 SPI
    375,000 btu

    How do I replace this?
    Are there any precautions I should be doing or extra servicing that needs to be done after this installation?

    I almost never say this, but please, please, hire someone.

    If you tell us your area I'm sure we can recommend someone good that will treat you fair.
