Capping off unused vertical steam radiator riser

branimal Member Posts: 130
I have a vertical steam riser pipe that isn't going to be used in the new configuration of my renovation. Initially I was just going to cap it off. The exposed portion of the pipe would clear the finished floor enough so that a cap could be adequately threaded on.

But I needed to shim up the floor in that area. So now the cap can only get about 3/8" of thread on.

I'm thinking I'll put a coupling on and plug the pipe. Just wanted to get a 2nd pair of eyes on this before I proceed.

This is a laundry closet.

    That should work fine. Put the coupling on before you raise the floor.
