I believe I have isolated two problems with the odors from the builder's disposals. The interior is NOT stainless steel, and the corroded surfaces harbor odor causing bacteria. In addition, the dishwasher drain is NOT routed through the disposal the way so many were "up north", where the draining water would flush out the disposal. They claim that this is to lower the noise level, but I suspect the caustic dishwasher soap was quickly rotting the lower quality units. Specify stainless if you have to replace, and some of the issues will go away. I always used a 3/4HP unit, and the instructions stated : break steak bones in half for best results. That seems more powerful than the units in new homes here.
