Product review (5 stars): A must have when traditional hoses are too short -- Can be used with many makes and models.
I needed an extra long drain hose for my dishwasher when I remodeled the kitchen.  The local building stores did not stock longer hoses, but I found this one.  I am using it on a non-Whirlpool brand dishwasher and a generic garbage disposal, but the ends fit fine, and I could have gotten adapters if I needed locally.  Be sure to install the hose with a high point as high as possible under the sink.  This will prevent a stopped up drain from backing into your dishwasher.
