Rated 5 out of 5 by from Quiet Very pleased. Gave it a 4 for installation, but my husband is a plumber and in that case it was a 5. Average individual may have found it a bit more involved.

Rated 5 out of 5 by from I think the Septic assist is a wonderful feature. I have had this unit for only a month. But as I wrote above I feel the Septic assist is a great feature. The unit is bery quiet in its operation. Overall I am very pleased with this unit.

Rated 5 out of 5 by from This product is very good because of the septic tank feature We have always been concerned about using the disposer because of the our septic tank. Now the new disposer has an additive feature that activates when the disposer is used. This feature will give us peace of mind and we will not have to worry about the septic tank plugging up. This makes good sense. I have not seen another disposer with this feature.

Rated 5 out of 5 by from Does the Job! We have an original late 50's septic system being a beach front property. Although the unit is not used frequently only time will tell how good and effective this unit really is. it is quiet and works well and is a good expensive backup for the sink strainer!

Rated 5 out of 5 by from Love it! It was time to replace an old incinerator that came with our house when we purchased it. We had an older model. This one is so much quieter. I can't speak on install, because our plumber did it! I can say the customer service leading up to this purchase was great so I only hope the customer service after the face continues to be as helpful. One thing I would recommend is to take a picture of your sticker with model number details before it's installed! It's very difficult to read the sticker when it's installed as it is facing the back wall of the cabinet. I needed this information to register my unit; and you would need it if you were to have an inquiry to customer service.

Rated 5 out of 5 by from Ideal product if you have a septic! We recently moved into a new house that didn't have a garbage disposal and we were told we shouldn't get one because it was bad for septic systems. After asking around and doing some research, we pulled the trigger on the Insinkerator Septic Assist product since we've had good luck with Insinkerator products in the past. I had the product professionally installed and so far after a month of use, we really love it! The BioCharge liquid seems to be lasting very well, and overall the product is EXTREMELY quiet.

Rated 2 out of 5 by from not too perfect Bought this product about 2 years ago. Worked fine with the first bottle of additive. Installed the second bottle and the machine does not take the liquid out of the bottle. Called for help and instructions. The sent me another bottle of additive with instructions to install it. Still does not work. Dissatified customer in Hillsville VA

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.
