enter image description hereInstalled new kitchen sink and the drain is 4" off from the existing p-trap.

The below pics illustrate my problem. Today I will buying a tailpiece with a dishwasher connect.

When the tailpiece is installed what other parts will be needed to align the tailpiece with the existing p-trap setup?

    Loosen the metal compression nut. Twist the trap counter-clockwise. Tighten the metal compression nut.

  • @brhans i'm not sure you read the question correctly. Commented Jun 5, 2018 at 13:07
  • That's how I read it, too, but it's difficult to tell from one angle whether swiveling the trap alone will do the trick. I'd be cutting off all the welded parts and installing a new reducer and threaded compression nipple, then using all compression fittings to complete the job.

    @TheEvilGreebo - from that photo It looks to me as though the open end of the trap needs to swing over to the right. Loosening the slip-joint on the trap would allow that to happen. It's not clear from the angle of the shot whether or not that would be enough - but it's what needs to happen first...

  • I agree but what he asked was what parts does he need. Commented Jun 5, 2018 at 13:34

This is a pretty standard issue. I'm a little confused why your drain end appears to have a permanent reducer coupling attached to it - but in any event they make a flexible, expanding part for just this issue: enter image description here

Just install it and force the pipe into the best fitting position. It connects to both ends with a compression ring.

  • You'd want to use this in conjunction with brhans' suggestion above. The bend would be pretty severe otherwise.

  • Agreed. You don't want any extreme bends or you'll be subject to clogging. Commented Jun 5, 2018 at 13:35
