Kitchen Disposer Waste Outlet Height
Posted by Jim on February 28, 2002 at 10:55:12:
What is the required and suggested differential height between the waste outflow of a kitchen sink disposer and the waste drain pipe directly after the sink P-trap? I would think that a height differential of about 1/4 inch would be sufficient, but see on GE's disposer installation sheets a suggested 3 inch height differential.
