This unit replaced a 20 year old Viking magnetic start/stop-top disposal. This Insinkerator is so much better than our old unit. It is very, very quiet and disposes its contents much faster than our Viking ever did. New high-tech sound proofing and waste grinding technology, I suspect, but it sure works well and quietly (not silently).
It was a little larger and longer than our old unit and required the installer to reconfigure the drain line connections, but that is why I had it installed and did not even consider the tight space under the kitchen sink as a “do it yourself” project location. It is also fairly heavy, but the installer had a neat little jack device. I recommend this Insinkerator Food Waste Disposer.
