I'm going to run a plumbing line for the nail spa chair, which has an underground sink. I would like to know how to run a loop-vent for the underground sink? Thanks a lot for answering!

Hi Tyler...

A spa chair shouldn't need a "loop vent"... should be OK just installing an individual vent for each chair. This chair should be piped up exactly like a tub drain.

What makes you think you need a loop vent?

Please respond/post a reply in the box at the very bottom of this page... thanks!
