P-trap under bathroom sink not lining up


I got new countertops and my P-trap is not lining up. What solutions can I do to fix this? I have read to stay away from flexible P-traps, but this is the only solution I see right now, unless I can find a 45* bend that is only threaded on one side (the pipe at the very wall exit is threaded) and I can take the straight wall pipe out, put that 45 on and cut the straight and then flip the p-trap so it faces towards the wall, but not sure that'll line up either...

Thanks!

I have one, but where does it go? The only thing I could think might work is if I remove the straight pipe from the wall and put the 45 at the wall, then the straight and shorten it, then flip the P trap around so it faces the wall side. The only problem is, the pipe at the very wall side is threaded, as is both sides of the slip joint. I'm not finding a one-sided threaded slip joint 45* and the other side clean. Or, I don't know how to connect 2 threaded pieces together?!

The other sinks were fine.

Thanks

Cut a short piece (about 2") of tubular pipe and use it to connect the 45 to the trap adapter. That will let you connect the trap to the 45

Question

Re: P-trap under bathroom sink not lining up


So you're saying I'd have wall pipe (I think that's called the trap adapter) which is threaded, a 2" piece of unthreaded pipe, then the 45* elbow (threaded both sides), then the other side of the angled wall pipe (~2") to go down to the P-trap which will be rotated probably backwards more?
Otherwise, I don't understand how I can attach the threaded 45* elbow to the threaded trap adapter at the wall - see my pic.

Thanks!

Re: P-trap under bathroom sink not lining up


Yes the threaded piece coming out of the walk is the trap adapter. Cut the elbow coming out of the wall in your first picture and leave a 1.5" stub from the wall. Connect the 45 to that.

Re: P-trap under bathroom sink not lining up


Could he also do a 90 coming out of the wall facing left and then face the trap straight back? Then he would just need the appropriate distance from the wall for the 90 and it will line up. Probably less elegant and more bends, but would that be allowed?

Would you want to snake that?

Wouldn't you need 2 90s? One 90 would then put the pipe parallel with the wall and couldn't connect the p-trap or straight pipe to that.

I think frodo's suggestion is the best. Will try that this weekend, if I have time!

Yes, that would be two 90's. Didn't sound like a great idea.
Please post up a pic of your final product.

Re: P-trap under bathroom sink not lining up


I'm back. I got strep and it hit my muscles weird and rendered me useless for a week.

OK. I cut a short piece, then my 45*, now I'm stuck again! The only solution I see is to flip the P-trap around and cut a very short angled down pipe section to go on the 45* (see pic, it's a bit tilted but that's just how I was holding it).

Anyone see another solution?

I can't slide the P-trap up any higher because it hit the stopper horizontal nub out of the tailpiece. So the angled down pipe won't reach. Cutting that tailpiece wouldn't do me any good then.

Thanks again..

Re: P-trap under bathroom sink not lining up


Your drain at the wall is too high.
Your solutions are to lower the drain, which means cutting into the wall and drain line.
Or find a shorter pop up drain assembly for the sink.
Solution 2 is the easiest.
