I am about to have my water heater replaced by a plumber. I want to make sure that the plumber uses dielectric unions or brass nipples.
I might buy some in advance to make doubly sure. What size would you recommend: is it 3.4" FIP or MIP?
And if I go the brass nipple route should they be 6" long or will shorter do?
Thanks in advance.
