Rerouting (black?) heating pipes
Posted by Orlando on June 26, 19100 at 14:25:00:
I'm planning to reroute heating pipes in my basement. (I'm not a plumber). They are rather low and to make the area more useful I want to cut a section of the pipes, raise the whole thing and rejoin them with compression fittings, elbows, or whatever.

The system (old gravity, now pumped) has mainly 2 inch pipes, plus a couple of other sizes but I'll be darned if they don't look like black pipes, not galvanized.

How could black pipes have lasted so long with hot water running through them? House was built in 1932. I've been here for 21 years.

Can I use black pipes? Can I join them to galvanized without corrosion problems? Can I use narrower pipes since it is now pumped?

Thanks for any answers.
