Hello all, so i am switching out my 3/4" copper supply and return lines, from my radiators in one room, to 1" copper. The 3/4" connection was originally reduced from 1" cast iron with a dielectric union. I have been told that, going from cast to copper, i didnt need a dielectric union.
so my question to you all is, what would you use at the cast iron 90 elbow to go to 1" copper?
this is hot water boiler setup by the way
