Good morning all........I removed old bathroom vanity, and purchased a new, freestanding vanity.......Problem is: rough plumbing (1 1/2" water pipe) that comes out of the wall is too low to allow for a 'trap'? I cut out the back of the vanity to allow the pipe to fit into the vanity, but it (the pipe) only has 2 inches of clearance below it, to the bottom of the vanity.......Not enough room to allow for a typical 'trap'.......Any ideas on how to get around this, without raising the rough plumbing? Any trap adapters, or something? I'm a complete novice.......

Thanks for any info...

-Bill

I thought of that, as a last ditch option? I'd like to avoid that, since (1) would take away storage space within vanity cabinet, and (2) would cause exposed plumbing under the 'decorative' vanity......It would probably work, but would ruin the look?

What is the purpose of the trap, anyway? i.e. Couldn't I just run piping from the sink drain, and elbow it off directly into the rough plumbing at something like a 75 degree angle? or, would that impede the water flow into the rough plumbing drain?

trap

Without getting into a class discussion of traps, siphonage, sewer gases, etc., suffice it to say you DO NEED a trap, and the solutions you are proposing either eliminate or negate the trap and its purposes. Either cut on opening in the bottom for the trap to hang into or raise the pipe. Those are the only two viable options to maintain the trap's integrity.

Thanks, HJ
ok.....it sounds like the quickest/easiest is to cut hole in bottom of vanity and, and move on from there......but......if I were to raise the height of the rough plumbing drain, how do I do that? The rough plumbing pipe runs horizontally through the studs in the wall, and then is positioned in its present location with 2-90 degree pvc fittings....(condo was built x 30 years ago?).......sounds like a plumbing project best left to a pro.......unless this is easier than I think, which I don't suspect to be the case......

I think I'll go with option 1.......cut a hole in bottom of vanity, and run with it?
