Furnace Expansion Tank Leaking

Over time it becomes logged with water or air starts to leak out of the tank and when this happens the pressure relief valve will start to leak.

Furnace expansion tank leaking.

It says hxt 30 12 psi precharge 5 gallon. The boiler expansion tank absorbs the expanding water by allowing the air in the expansion tank to compress this prevents the pressure. If the tank is on the hot water heating system then it s there to relieve expansion from the water being heated.

Leaks tend to travel down with gravity if you see evidence of a leak above the tank then it s likely at the top of that evidence not the bottom.

The changes in pressure inside the expansion tank can bring about the degradation of the water heating system and cause leaks. The furnace relief valve from the boiler or plugging it so that it does not leak is a very bad idea this can allow the. Before even considering expansion tank replacement if the water leak you are describing is not at an air charge vent on the expansion tank itself a part that is indeed not present on most bladder type expansion tanks for heating systems then you are probably talking not about a problem with the expansion tank but rather a problem with an automatic air bleeder vent a separate.
