Consider this: if the galvanized pipe is leaking where it joins (is
screwed into) a COPPER pipe, be aware that the leak will probably come
bake after a few years. Galvanized to copper is a bad deal. You should
change to all copper if that is what you have. --Phil

Hi all,
I found a pin hole leak on a piece of galv. pipe that goes from my hot
water heater to the expansion tank mounted above the heater.
