We have recently replaced the sink in our kitchen with a Kohler single basin deep sink. We wanted to add a 3/4 HP garbage disposal unit. The problem is that if the disposal is attached to the deep basin sink the discharge tube on the disposer is several inches lower than the the heighth of the waste water pipe entering the wall.

Relocating the waste pipe in the wall is not an option as it would require removal of granite counter tops, cabinets and tearing up a wall.

Does anyone have any suggestions? Is there anything like a small "lift station" pump that would work and would be in compliance with codes? I appreciate the help.

Thank you.
