I am installing a pedestal sink. The drain and hot/cold were not vertically aligned with the light fixture or medicine cabinet opening during rough-in. Seeing as I had to open the wall to add blocking to support the sink, I made the hole a little larger and would like to adjust the plumbing so the finished job looks right.
This rough-in was done w/ PEX. There is a transition to copper for the shutoffs (which were never installed). The drain is PVC.
There is enough slack on the PEX to move the hot/cold over. But the copper "stubs" at the end of the PEX seem to be soldered to the copper strapping that is screwed to the wall. They wobble in the strap, though. They won't go in and out because the solder on the "stub" has formed a ridge in front of and behind the strap. But they do wobble around. Shouldn't these be tighter?
To move them, do I just heat 'em up w/ a torch and pull 'em out? Any danger of doing this with the PEX already connected to the copper? Will this work now that there is water in the lines, or will the water prevent the copper/colder from heating enough? Safe to at least try it?
Is there any concern in extending the PVC by adding a coupler? Will it cause the drain to clog more often?
Oh, and the hot/cold are closer to the floor than the drain. Is that normal/okay? In my other bathroom the hot/cold are HIGHER than the drain.
I don't have tools to work with the PEX or replace the copper. I was hoping to make the adjustment, close-up the wall this weekend and place the sink, then have a _good_ plumber finish-up by installing the shut-offs and finishing it up.
Any tips on how to do this job would be greatly appreciated.
