Just got new counters and a under mount sink. NOW the bottom of the garbage disposal is about an 1/2 inch above the drain in the wall and I can NOT hook it to the other side... help

I do NOT want to cut drywall, cut pipe in wall and then put a new drain lower:mad:

Options? - 1. I was told I could add another P trap just for the garbage disposal and put a Y on the drain at the wall giving each sink its own drain/P trap.
2. simply get rid of the garbage disposal and put a new sink drain and put it back together -be done :cool:

Wifey says she would like to keep the garbage disposal but I can't get water to flow uphill!! Advice anyone??

You were told right about adding a wye in the line and then running to the disposal with another trap. In fact this sometimes works better because when you run your disposal it does not have a straight line to pump water back up into the other side of the sink.

If you do not have a clean out for your sink line this would be a good time to add another wye and use the opening for a clean out. But if you already have a clean out then never mind that idea.
