Hi,
This question comes up alot but after searching the newsgroups I can't find a definitive answer to the following question:
I need to replace my old water heater with a unit made by Rheem. This Rheem tank has female tappings but no nipple connectors.
I am worried about galvanic corrosion at the water connections. The house has copper plumbing.
Is it best to connect the copper lines to the heater using brass nipples and brass adapters? Would it be better to use galvanized nipples and dielectric unions? I've even read that a male copper adapter straight into the tank is best. Which would you suggest?
Thanks
