Expansion tank

caspermccormack · 2008-09-03 19:19:21

I have a leak in my heating overflow/expansion tank, it hold about 4 gallons of water. Noticed a small weep on a conection and found i could put my finger through it!(rust), anyway is it ok to replace it with a plastic one from a hardware store, or does it have to be metal? Thanks in advance for any input Casper.

Consider replacing them both, the other one holds a lot more water and if it lets go you will be replacing a few ceilings.........

Sorry the big water tank in the attic is plastic, the heating one is metal or rusty metal, had a fair idea to replace it with a plastic one , just asked incase there was a reason for it being metal.
