I have a 1996 Weil-Mclain forced hot water heater with a Beckett oil burner. The system has been great since it was installed. Like all things it now has had issues. First, off the Amtrol 30 tank was replaced, the tankless coil for Domestic Hot water has been replaced. Last week the city was working on the water lines and it is a High pressure they screwed up and charged the line up to high and an air slub hit the heater the backflow preventer was damaged and the pressure reducer was shot both replaced and we found one circulator was gone as well replaced with new. The issue is I also replaced the pressure relief valve and the temp/ pressure gauge and all looks fine pressure remains between 15 and 17 PSI and temp runs between 180 and 200 same as always nothing was changed but the relief valve is leaking and pops off when it is running and hits top temp. It is a Watts 374A good to 30PSI and the system never runs past 17 PSI. Stumped? is it bad even though it is just one week old or am I missing something else? Heat is great in the house and hot water is plentiful no other issues. Any info greatly appreciated.
