Gas Boiler
Posted by Fred Barrett on January 31, 19100 at 14:28:45:
I have a gas boiler that I just replaced the watts regulator (water feed) valve. The boiler works fine but it always reaches the red zone when the pump fires and causes the pressure relief valve to open. I bleed the expansion tank and the baseboards (only water is released, no air is left)to no avail. I am at wits end, any suggestions??
