I have been trying to remove the P Trap to clean it. I can turn the 1 on my right to loosen it. However, for the 2 on the left, I can’t seem to loosen it. It won’t budge left or right. Do I need a plumber’s wrench? Also which direction should I be turning it?

Thank you enter image description here

  • My preference is for channel locks when needed. Usually with plastic drain piping it should only be hand tight, so once you get it loose don't tighten it too much. I have converted to plastic for this reason-it is much easier to get tight than metal. Apr 20 at 4:31
  • Generic comment irrespective of which answer you favour. Do not use generic mineral oil (including penetrating oil) on plastic, it often has enough of a solvent effect to make things worse by slightly softening the plastic. Apr 20 at 7:31

Use a large pliers or pipe wrench if you can't turn it by hand. Lefty-loosey, righty-tighty (from the perspective of the part without the male threads--top down for #1 and bottom up for #2).


Fully undo 1 before 2.

It may be the angle of the photo, but it looks like the whole trap is at a slight angle. When threads are subject to an angular misalignment, they will bind, so make sure the piping is fully relaxed before you attempt to loosen the stuck nut.

  • It was just the image was at a weird angle. Thank you!

  • There is a slight dogleg at 1. Unfortunately this isn't correctable since the trap arm is cemented. I don't think it's enough to be a problem, though.

Use any wide-mouth turning tool, such as a pipe wrench, footprint, strap wrench, multi-grips.
