I installed this disposal in a 16 gauge stainless sink with sound dampeners on the sides and bottom. The pneumatic switch fit where the soap dispenser went. Perfect fit. When running empty; I can barely hear it running. It has a three speed grinder speed and works great for septic tanks. I didn't get the enzyme injector for it because I monthly pour enzymes down the toilet.

I'm a professional plumber and have been installing ISE disposals for a long time.
