Original problem was that my boiler was running a little high and making some banging noises. So lines were bled, aqua stat replaced. works fine for a bit, then when i check temp again its getting to high again. Guy comes back replaces relay. "says that should do the trick" come how a few hours later and my pressure relief valve went off and came into a puddle on my floor. Then comes try three he replaces Expansion tank Expansion valve, Hi Vent, Temp/ Pressure Gauge, Pressure reducing valve. Works for a few hours. I'm sitting on the couch, hear a sound. ITs the pressure relieve valve letting steam out, check temp gauge it reads 270!!!! what the heck is going on? does this guy know what hes doing?
