kitchen plumbing problems

[desmoface]

Hi HJ, I measured and the bottom of the drain pipe is about 18" from the floor. I think we decided to go with a little smaller sink in which the smaller of the two (double sink) is about 5" deep. Should eleviate any problems...Thanks again for all the info and replies..

My kitchen sink worked fine before. Recently, I had a new, deeper sink installed (10" deep; also bigger in length and width), with a new disposal, and got rid of the air gap. Now, when I pour a pot of water in the sink, it drains down very slowly. If I turn on the disposal, the water goes right down. Will an air gap help drainage by allowing the air in the disposal to escape to somewhere? Is the bigger/deeper sink somehow causing this problem?

Thanks,
Steve

The dishwasher air gap will not help the sink drain.

It for backflow.

If you have a deep sink, you may need to lower the trap arm at the wall.
