We purchased this disposer for our cottage in northern Wisconsin. Never had one before because we were concerned about the septic system. Found this unit, designed for use with septic systems, and couldn’t be happier. Installation was straightforward, with easy to follow instructions. Unit is very quiet, and chews up just about everything without any effort. Well, except for the dish rag we put down by accident, but even that didn’t jam it, we just heard a weird noise and shut it off. Great product, great feature with the bio-waste chemical it injects to aid the septic system. We also bought an air-activated pushbutton switch to turn it on. Neat innovation that uses air hoses to activate power…much easier than rewiring a wall to add the switch. Works flawlessly.

Have this in my personal home. Just bought it for my vacation home. Gets rid of everything with no apparent effort and low low noise.

We bought a house with a septic system and then a plumber told me I couldn’t have a garbage disposal and I found this one. I love it. It’s not as quiet as they say it is. But it doesn’t bother me one bit!
I have a great garbage disposal and that is what I wanted. It works wonderful!

Had this product installed and working in no time. So glad to be able to finally have a disposal that works with a septic tank. It works like a charm.

I’m really glad to finally have a disposal for this house that is on septic. No matter how diligent we were, some food particles always ended up in the sink and periodically caused drain line problems.
Installation was straight forward even though I did not have an existing disposal to replace. My two biggest challenges were getting an electric outlet under the sink and removing the old corroded sink flange.
For electric I mounted a GFCI outlet under the sink and added the optional power cord kit and sink top switch. This eliminated the need to add a wall switch since I did not have an existing disposal.
To remove the corroded flange (5 minutes max) I used a moto-tool with cutting wheel – I was working solo and didn’t have anyone to help me muscle the old nut and flange apart – it just kept spinning in the sink.
As mentioned elsewhere the only other thing I needed to purchase was plumbers putty, and I bought a new hole saw for my drill to drill through the solid surface countertop for the sink top switch. Under the sink I was able to reuse all of the existing PVC plumbing where new parts weren’t provided.
After a month of occasional use the Septic Assist bottle is still 7/8 full. I will still maintain the septic system with pumping every 2-3 years but I’m hoping this helps with the drain line issues inside the house.
It is much quieter than I expected and the sink top switch works great. I couldn’t be more pleased with this product.
