How to Hook a Dishwasher Drain Line to a Kenmore Disposal
If you decide to add a Kenmore waste disposal to your kitchen sink, you may wonder where the dishwasher drain line, which usually connects to the kitchen sink drain, comes into play. Kenmore disposals have a dishwasher drain outlet fitting. The drain line from the dishwasher connects to the fitting on the disposal instead of the sink drain pipe. A plug blocks any waste from coming out of the fitting on installations where there is no dishwasher. Does this Spark an idea?

Tips & Warnings
Some dishwasher manufacturers require that the dishwasher drain hose be connected to an air gap. An air gap prevents disposal waste water from siphoning back into the dishwasher, which can cause odors in the dishwasher. Air gaps are usually mounted on the top of the kitchen sink. Once the dishwasher drain hose is connected to the underside of the air gap, the hose from the air gap should be connected to the dishwasher drain outlet fitting on the disposal. More-detailed instructions should come with the air gap.
