You’ve seen them… those small chrome cylinders with open slots installed on your kitchen sink deck or counter top. Have you wondered what that silver thingy is?

It’s an air-gap device that’s installed between the dishwasher drain hose and the garbage disposal. The purpose is to prevent ‘dirty’ discharged water from the dishwasher flowing backwards into the dishwasher, if there’s blockage at the garage disposal unit.
