For years as a plumber we were able to install an inexpensive disposal and they would last ten to twelve years. Unfortunately those days are long gone. The quality of disposals has gone down dramatically. The last time I installed a $79 disposal (three years ago) it didn’t last six months before it started leaking. Most people don’t want to see their plumber that often.
At that time we started recommending the evolution series disposals. We sent our customers to the big box stores to pick them up to save them money. Recently the big box stores started selling a substandard quality disposal than we can get from our plumbing supplier.
So the Evolution Pro 750 is the least expensive disposal we recommend to our customers unfortunately. When our customers call us out we like to make our repairs and installations last as long as we can make them last. This disposal has a stainless steel grinding chamber to provide years of leak free use. It has a dual grinding chamber to allow for items which were not recommended to put in the disposal for prior models, has a 3/4 horsepower motor (the original ones had 1/10th or 1/3 horsepower!), auto reversing capability to prevent jamming, six year in-home warranty, and is so quiet you can hardly hear it running. We supply and install this disposal for $475.
