New kitchen sink not draining properly

My sink is not draining.

I just completed attaching my new sink to the wall drain and the water backs up.
I recently renovated my kitchen and put in new cabinets, counter tops and a sink.

Please reference the attached photos.

Thank you for your assistance in advance.

Jim

Did the old sink drain okay? Could construction debris have entered the drain while remodeling?

The old sink drained properly. The previous sink was less deep and a top mount, the existing is deeper and mounted to the bottom of the counter top. Therefore, I had to remove the garbage disposal as the drain was lower than the waste pipe and the sink would have a very slow drain and back up. I redid the plumbing and it still drains slowly. I thought there might be debris in the plumbing and snaked the pipe as much as I could and it seemed fine, at least as far as I could go, to the bend in the basement. Thanks.

Another quick question, how does my trap look height wise? It seems to me that the water should be flowing properly. Thanks. Jim

How far is the trap arm inserted into the pipe in the wall? If you did not trim that arm and stuck it in too far it may be hitting the back of the tee or elbow and blocking flow........

Welcome to the forums.....

Good question. I did trim the pipe so it is not going too far into the wall and double checked it just to make sure.
Thanks for helping.....

just to check everything disconnect trap where it goes into wall and put a bucket under it. Run water in sink and make sure sink and trap are clear. If clear you have a problem in drain pipe.

Sink and trap are new, therefore there are no obstructions.

You trimmed the trap arm back, but did you first test fit it?
You may have pushed sludge back into the tee.
If you have an old cast iron tee, they are less forgiving and don't flow very well.
This would be a good project. Replace tee in wall with ABS, at the same time lowering it.
This will allow you to have a disposer. With an ABS tee, you will see immediately how better your drain flows.

While you were changing out sinks, you didn't happen to stick a rag in the drain pipe ( smell suppressor ) and forget to remove it???

I had a plumber put in my old garbage disposal and do the connections. I got burned and have been trying to fix the problem ever since. Your solution would probably work, however it would be a very big job. My pipes are behind plaster walls and not very accessible from the basement below either.
Thanks.
