Furnace Expansion Tank Leaking

I never had any problems with overflow leaking with the old tank for 5 years.

Furnace expansion tank leaking. There are two types of expansion tanks used with hot water boiler tank systems. 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. An expansion tank is a small tank that protects closed and domestic water heating systems from excessive pressure. The expansion tank is the same size as the one that was there bout the size of a propane tank maybe just a tad smaller.

The boiler expansion tank absorbs the expanding water by allowing the air in the expansion tank to compress this prevents the pressure. The changes in pressure due to overflow from the boiler during water expansion as well as having moving parts makes for the potential for degradation of the system. The expansion tank is water logged. Steel expansion tanks and bladder expansion tanks.
