Rated 5 out of 5 by from Simple installation and great support I needed to replace a 17-year-old unit originally installed when I built the house. It started leaking so I contacted support for advice. They quickly informed me that it needed to be replaced for which they provided a discount code. Shipping was fast and installation took less than 30 minutes with their innovative interlocking mechanism. I didn't have to do anything with the sink trap. Just disconnect the dishwasher and drain line. Then hook up the power and done. As easy as it could possibly be.

Rated 5 out of 5 by from This disposal is quiet and the gasket is easy to clean It has been some time since I've had to purchase a new garbage disposal. Maybe that is because my last disposal was an Insinkerator and lasted 15 years! I have two sinks with disposals. The new disposal is so quiet and the rubber gasket is removable for easy cleaning. That is my favorite feature!

Rated 5 out of 5 by from So quiet !!! So my old one died after 18 years, I ordered a new one and had it in like 4 days, after a little trial and error I was ready to give it a try and when I turned it on my first thought was rats I did something wrong my wife said just put a potato down and see what happens, well as it turns out I did install it right it was just a totally different "hum" we were use to. Works great.

Rated 2 out of 5 by from Bio-Charge Does not Disperse This disposal was purchased because it was made for use with septic tanks. The garbage disposal works fine. Because of the septic tank, we do not grind anything large. We use it to grind up only small pieces of food. However, the bio-charge liquid did not disperse. The company sent a new disposal and our wonderful plumber put it in free of charge. The quality of the second disposal does not seem to be as good as the first disposal. In addition, the second disposal was an inch off so the plumber had to change our pipes to make it fit. It is not worth the extra money. I would not recommend this disposal.

Rated 5 out of 5 by from Recommend, especially for installation in a strong sink We installed this garbage disposal in our new house after being pleased with its performance in our previous place. I don't worry about clogging up the septic because it adds a solution to aid in biodegrading. I was concerned that we may use lots of solution, but I only need to change bottles every year or so. It is very powerful, so I recommend putting it in a sink with heavier gauge steel. Our first place had a cheap sink, and it vibrated a lot. Installing it in a sink with 18 gauge steel is perfect; it is pretty quiet, considering its strength.

Rated 5 out of 5 by from Replaced a previous insinkerator that was 13+ years old Replaced a 13 year old septic insinkerator with this one. Customer support was excellent, new one shipped and got installed the next day. Much quieter then the old one, hope it lasts as long!

Rated 1 out of 5 by from Doesn't work well I am only using this disposal to grind simple food, like rinsing plates before washing. The orange peel I put down took several days to work out, and that was even with me turning the disposal on and off several times. I can't get my hand inside to pull the peel out, so had to keep working at it.

Do you have to purchase the flange seperately, or does it come with the unit?

Asked by: Buyer
No, you have to buy it separately!

Why does the Bio-Charge bottle keep falling out?

Asked by: Donna9093
Make sure the bottle tip has been turned and it will pop up. Then it should click securely to the unit.

Does the product come with an initial bottle of the septic assist liquid?

Just had local Lowes install my new Insinkerator this week and tonight, when the disposal wouldn't work (the pneumatic tube from the sink button had disconnected) I discovered there was no bottle of septic liquid attached. Should the unit have come with one?

friend has a brand new one of this model but didnt use it. Can I use it .. I don't have septic.

I don't have septic. I am on city but I need a new unit, would like to have that USA made Insinkerator .....Can I use this???
Asked by: poodog
Sure you can but you don't need it. This unit has an enzyme tank that injects into the disposal to help septic systems. It is more expensive than a conventional unit.
