We have a new sink we just installed that is off set from the waste water pipe. The pipes we have leave a 2 inch gap between the p trap and the flaired pipe attached to the wall waste water connection. We can't make the sink tail pipe any shorter, we already cut off about 2 inches. Any ideas on how to close this 2 inch gap? Thanks!

You're saying the wall stubout won't match up with the trap. Correct? What flared pipe are you talking about? What material is the stubout ? Copper? Plastic? Galvanized? What material is the trap? And what's this?

What ,exactly do you call the "sink tailpiece"? Would this be the tailpiece from the lavatory, (sinks are in the kitchen) or the trap tail? Please explain. I've put up a lavatory cutaway so you can explain your problem a little easier. Why did you have to cut 2 inches off from anything and what part did you cut. Help me to understand your problem.. I'm really trying. Tom

Tom, thanks for trying to help us. (I am not a plumber:))
The part my husband cut was the drain pipe that comes with the pop up drain piece. He said it was called a tail pipe. The proplem is the new sink is about 1 inch deeper than the old sink. The waste water pipe in the wall (looks like galvanized) is too high for an easy fit. By shortening the drain pop up tube (tail pipe?) it enabled him to insert the p trap into that pipe at a high enough level to make it even possible to finish the connections. Connecting the p trap to a pipe that goes into the waste water pipe is the problem. We are using plastic pipes. And we have to go from the p trap up and at an angle to the waste water pipe coming out of the wall. My husband is worried that the sink is too low for efficient flow out toward the pipe drain, even if we could fine a 2 inch part (1 1/4 in) to fit the gap.

One way to solve this problem is to reverse the P-trap. When you do this you may have to add an extension to the tail piece that you cut off. This is not the right way to connect a lavatory but it will work.

You could reverse the trap as Letmetellu suggested or if you need more room to cut back and the pivit rod's in your way you could swap the pop-up drain for a Pull out plug and chain drain,(see image). That yould give you some extra stock you could cut back on.
Whichever works best for you. Good luck, Tom

Hi Patty...

Letmetellu is correct if you are using metal parts, but since you have indicated that you are using plastic parts you could:

1) Install a deeper ptrap. Here you could take some pvc 90s and street 90s and make your own ptrap... just slightly longer/deeper if needed. If you do this, if possible, would be nice to install a dandy cleanout in line as well... see picture.

2) Use an 1.25" flexible tailpiece... see picture. This may help in offsetting the tailpiece if needed as well.

3) They also make a flexible ptrap... see picture.

Just my thoughts on this...

You now have lottsa options.. Choose the one that works best for you. Good luck, Tom
