I had a counter and sink installed in my bathroom. The new sink is undermount and sits a little lower than the old one. I did the drain piping using abs plastic.
At first everything was fine I think. Now if I run the tap for more than 30 seconds it wont drain and fills up my sink. It can take several minutes to drain down.
I want to know if my piping sits to low and there isn't enough pressure to drain or if my condo has a possible blockage in the piping causing this.
My pipes are all clear, I mostly need to know if my plumbing acceptable to drain. Thanks

Why are you going from, what looks like 1-1/2", up to 2" for the trap, then it looks like it's reduced back down the 1-1/2"?
I am not a plumber, but I would imagine that that could cause a bit of an air lock.

It shouldn't take any pressure to drain; gravity does all the work. I assume your plumbing stack is clear.

Does the pipe behind the wall sit higher than the current height of the sink drain?

Must be the picture, it is all 1 1/2" abs.

The copper pipe exiting the wall should go straight out to the condo main stack. You can only see it for about two feet then it twists away, but it has to be straight out.

So I guess it is a clog somewhere and not piping.

plumbing looks good

I would take it all apart to make sure nothing fell in and is blocking your drain.

plumbings fine.

its normal to go from 1 1/4 to 1 1/2 abs to 1 1/2 copper, there's no air locks or anything.....

check the mechanical pop-up if its sitting high enough letting the water thru or if anything is blocking in the tail pipe. if there's no blocks and and the pop-up is sitting high enough then its blocked further down the line.

Yea, the plumbing looks fine, check to see if anything is causing a blockage.

I have a small snake I managed to get in about ten feet and found nothing. I'm stumped, I guess I'll have to get the condo to bring in a plumber to check for problems on their end. Thanks for the replys.

I'm having the same problem as you B20ef with my kitchen sink with a garbage disposal unit if it makes any difference. It's not draining at all really and I just ran the dishwasher and my kitchen was covered in water, from the water not draining out and it goes up into the sink.

I took off the P pipe to see if anything is blocking and it's clear.
If I turn on the disposal then all the water goes down so i'm not sure what the deal is
Next step would be to snake??? or call to the plumber

^^In case you haven't dealt with it yet a snake is a good first start. Mine was completely coincidence with the timing of me putting a new sink in. I had major blockage far down the pipe and had to have it augured out, the snake wasn't good enough. It was like a little saw that cut away and cleared my pipe.

Very cool. I will have to get myself a snake to help with my drainage issues.
