I installed a new bathroom sink. I turned on the water and it will not drain from the sink. I instaled everything new. But do the center of the sink drain in a different location I had to lenghten the drain line into the wall. The only way the water will drain if I adjust the p-trap. I have lenghten the pipe and shorten but to no avail until I stated losen the p-trap. What am I doing wrong?

Hi Charles

It sounds like you have the pop-up assembly pushed too deeply into the PTRAP.

Cut an inch or two off the pop-up assembly if this is the case and you should be back up and draining properly, OK?

If this isn't the issue, then I can only begin to make guesses from here... ;)
