I have a Amtrol #30 expansion tank that I think needs replacement. I am getting quite a bit of water coming from the pressure relief valve that I am catching in a bucket. I checked the pressure of the tank and it reads 12 psi. I think the expansion tank bladder has a hole. When I tap on the tank there is no difference in sound from top to bottom.
My question is:
1) My home is a small ranch with 2 zones. Is 12 psi the correct pressure?
2) Do I have to shut down the furnace and the main water supply and drain the heating system completely before replacing the expansion tank?
3) Is there anything else I should do or know about before attempting this replacement?
I am a bit of a novice when it comes to heating systems but I did successfully replace a Taco circulator with no problem. Any assistance would be appreciated. Thank you
