The disposal was installed by developer. I believe the 1/2 hp disposal is to small. A 3/4 hp would have been better. This item is noisy and sounds like it is straining to eat a lot off waste at one time. i have not had any trouble with it but I have only been in the house for two months. Let see what happens in two years..
I am very disappointed in this garbage disposal. Water puddles and does not run through freely. I have to put my hand in the drain to help speed the flow. It is also very noisy.
