Rated 5 out of 5 by from Wonderful Unit This Insinkerator disposal is so very nice as we have a septic system was worried but this unit is made for septic systems. Just to be sure we had someone we knew (a plumber )put it in and had no problem now it is nice and secure. I couldn't believe how quiet this disposal is and the pricing was excellent.

Rated 5 out of 5 by from Great product for septic owners. Runs quiet This product replaces my 13 year old disposal of the same kind. This one is quieter because it is new. I hope to get at least 13 years out of this one.

Rated 5 out of 5 by from Efficient and quiet We built a new home which is on a septic system and out builder discouraged adding a garbage disposal. I began to research septic safe disposals and found the Evolution Septic Assist. After moving in, we had it installed, which only took about 30 minutes. The disposal works very efficiently and is fairly quiet, which was important to us.

Rated 5 out of 5 by from Third one and quietest thus far. I had purchased the first one in 2000. When it became defective within the warranty period, the company did what all great companies do...replaced it without any extra cost so when that one went (15 years later), it was a no brainer to replace it with another one.

Rated 5 out of 5 by from Quiet I am amazed at how quiet this disposal is. What a luxury!

Rated 5 out of 5 by from Nice disposal, quiet and powerful Install was fairly easy, a couple trips to hardware store to turn my double sink standard drains into one side disposal. Unit is large, but that is where the power comes from and it’s quietness. Didn’t need the extra dishwasher attach kit, mine went right on.

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.
