I have a 1 pipe system with dry returns. Lots of issues that I'm working on and one of the (many, many) solutions I'm tossing around is getting rid of the dry returns and switching to wet.
One reason is because I believe it's ok to use copper for wet returns, correct? That would save a ton of money. The other reason is because I would then have more than enough black pipe taken out to perhaps re-use to change one of my radiator supplies to black pipe as it should be instead of copper which it is now.
Would that be possible?
