Radiator line under slab
 

I am putting down a new floor but before I do I want to bury a radiator line under the slab that is exposed from previous owner. I searched and read here that it should be buried under the slab, not in the slab. That was one question I had. Another question is should it be bent instead of using fittings under the slab. Someone told me this and will hire a plumber if this is the case. I planned on sweating the pipe myself and just get someone to bleed the line. Tring to do as much as I can on my own.

Thanks

I'd use Pex not copper.

Are you talking hot water heat?

If so consider PEX piping under the slab not copper---which ever you use under the slab is best for a transition line.

use hydronic pex tubing for heating under slab..don't put any sweat joints underground...picture would help...:yes:
