Query: Piece of junk

Our Badger 5 is 4 1/2 years old and was installed by builder in our new home. It has now developed a leak and we just noticed heavy rust on the entire 3 bolt housing. Haven't determined cause of leak, but have ordered a Waste King L-8000 from Amazon and can't wait to replace this unit. Unit is noisy and under the best of circumstances, takes forever to dispose of food.
