The gas water heater tank I replaced is >15-20 years old. The Brand New Water heater I bought doesn't have instructions. Do I need to put a washer/gasket where the iron nipples/ short iron pips come out the top of the tank and meet the corrugated Copper pipe? It is was too corroded to tell if one was there in the past or not. Most any advice greatly appreciated.
Of note, the short iron pipes are already connected to the water heater and they have some kind of "Dielectric??" plastic protector on it. Will this make a washer unnecessary?
Thanks Greatly
