I am removing my old dual drain kitchen sink and installing a single drain sink. Where the PVC comes out of the wall will be too far left of the drain on the single bowl sink. I was wounding what would be the best configuration. I would prefer not to bring the PVC further to the left inside of the wall. Can I run like a "45" over and use my old S trap up to the single drain. Would this run into any problems not having the PVC go straight into the wall but doing a 45 then in? Thanks for the help.

You want the most direct passage for your drain. More horizontal angles would mean opportunities for more clogs. I did have to do this as a temporary solution, but I used a 22.5, not a 45 and I made sure I positioned it not too close to the trap or the point to which it exists through the wall for the best flow.

If you can move the sanitray T (or vertical fitting) so that you can position the drain for direct passage without any angle is the best solution.

Do you mean P trap instead of "S trap". (An S trap will siphon itself).

You may use the 45 to pick up the trap but your post is confusing.
You speak of a "S" trap going into the wall but "S" traps go into the floor not the wall.
Sooo, what is it? A "S" or a "P" trap? If you have a "S" trap I would advise installing a AAV,(Air Admittance Valve) on a sanitary tee before dropping through the floor. Regards, Tom

Sorry it must be a P trap then. The drain goes into the wall not the floor

Use the 45. That's the way we pick up our traps when we have to pipe to them. Good luck, Tom
