Winter return repipe project
The more I look at the end of my main, the more I don't like it. It cuts across one side of my basement to the boiler which is centrally located. At 64 inches off the floor, it is a perfect height to smack my forehead. And it adds 10 feet of travel to the main vent that isn't necessary.
Instead I want to drop it right after the last radiator runout, and make it a wet return that runs on the floor. I'll put wooden ramps on either side of it to minimize the trip hazard and protect the line. Have a look at the attached drawing that I think shows everything.
My main question is: copper or steel? I don't mind working with the steel and I don't think either will rot out before I do (ha!)
The existing end of the main is 1" and so is the wet return. Would that be an OK size or should I up it to 1-1/4?
My last question is: does anyone see any reason why not? Thanks all, and let me know if I left anything out.
