I just finished remodeling my original 1970 kitchen. The last step was
the new silestone counter tops and new sink. My General Contractor
(GC) told me to pick out the new sink so I chose an undermount deep
double sink. My GC's "plumber" tried to install my original
Insinkerator garbage disposal and discovered that the height of the
disposal drain outlet is lower than the drain line going through the
wall.

Water will just not flow out of my house.

I had the plumber remove the garbage disposal and water drains, barely.

The previous sink was much shallower. And, I can't change the new sink
and new countertops.

I haven't called my "real" plumber yet but the GC's plumber is telling
me that someone will have to rip out the back of my cabinet, cut into
the plaster and concrete block, just to lower the drain pipe.

Are there any garbage disposals out on the market that address this
problem? I can't be the only one out there remodelling a kitchen
facing this problem?

I really don't want to spend $500 to rip out my wall, lower the pipe,
and repair the wall.

Oh, and I am trying to sell my house. The kitchen remodel was supposed
to help with the sale, but now I am selling a house without a garbage
disposal.

Help!!
