Product review (5 stars): Easy to install - confirm you NEED and WANT it (dual sink snafu)
I utilized another reviewer's feedback in order to confirm I did indeed need this adapter: I was planning to leave the existing 3-mount of the old disposer (Badger 1) and use this adapter with a new EZ-Mount (Waste King 8000). The removal of the old disposer and modification/installation of the mount with this adapter went smoothly and was very simple; HOWEVER, once in place I could see there would be a drain issue unless the plumbing connecting to the other sink & trap were modified (lengthened & lowered). Leaving the 3-mount and adding the adapter effectively lowered the drain outlet from the disposer placing it lower than my existing drain connections, meaning gravity would not work in my favor. I opted to install the disposer without the adapter and removed the original 3-mount assembly from the old disposer. The product and installation instructions are perfect - I just didn't want to modify my existing plumbing piping and did not need to once I installed without the adapter.
