Plumbing – I am relocating a sink. Can I leave the original plumbing in place and cap it

plumbing

I am relocating a sink and I am rotating the tub (actually replacing the tub with a shower) in position and it will cover the area under which I have the drain for the current sink
Should I remove it prior to this or I can leave it where it is and cap it and hide it in the wall ?

Best Answer

You can cap it, but you have to use an ABS glue cap, not pressure fitted coloured caps.

If you are cutting anything back, past any T or Y connectors, make sure you do not sever the dry-vent connection to the rest of the plumbing.
