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?0 -
