    New sink drain 2" off from existing drain
    Sorry for the dumb novice question, but thanks in advance for the advice.

    My new lavatory sink's drain is 2" away from lining up with the existing p- trap drain pipe. I REALLY don't want to cut off the whole p-trap drain to install a new one that would fit where I need it (as someone has already suggested to me).

    Is it okay to be using 90 degree elbows here? Would I have to worry about it clogging?

    Or am I better off just buying another sink where the drain lines up better.

    The P trap doesn't need to go straight back. You should be able to twist stuff around to where the wall tube lines up with the trap. You may need to cut it to length, or splice in more. If you do have to use elbows try to use 45's instead, and make sure they are the longer drain elbows and not the regular ones.

    You don't attempt to match the lavatory up with the trap, you match the trap up with the lavatory tailpiece. You're 2" away which way? Too short? Off to one side? Labman was correct when he said the trap doesn't have to be straight. It can swing 3" to either side for a chrome trap and 3 1/2" for a PVC trap. Let us know exactly what sets where and the Labman and I'll do our best to get you back in business. Cheers Tom

    OKay, I'll try to describe this...

    The existing P-trap drain pipe opening is 9 1/2 inches in distance from the back bathroom wall. The drain-hole on the new sink measures only 7 1/2 inches in distance from the back wall. So it is 2 inches off to the rear. The height of the new sink is correct and is not a problem. There is also no problem with distance from the left or right.

    THanks for your input!

    They oughtta call you Lucky instead of Kelly,
    All you have to do is cut 2" off the stub out and couple back the trap and reconnect the lavatory to the trap. Don't forget. In plumbing all measurements are measured from center to center. Good luck, Tom
