Waste 1 HP King Food Disposer SS8000 Series

Pros: Lifetime warranty. Higher RPM than ISE.
Cons: ISE model looks prettier but who looks under the sink?

This review is based on my comparison of the Waste King Garbage Disposer SS8000 over the Insinkerator ISE Model 777.
There is a chart that compares all of the waste king models to ISE models at waveplumbing.com. After my disposer was installed I noticed that it is much quieter than my old ISE. The higher RPM and longer warranty helped me make my decision to select Waste King over ISE.
I'd much rather have a lifetime warranty with Waste King than a 7 year warranty with ISE. And it makes sense to have the extra motor speed for the same price. Waste King at 2800 RPM over 1725 RPM with Insinkerator.

Pros: Waste King costs less than ISE.
Cons: ISE is worth the additional cost. More torque. Larger grind chamber and opening.

Comparing the Waste King SS8000 (1 hp) to the ISE 777 (1 hp).
The ISE will have more torque, since horsepower equals speed times torque. The WK claim of more speed means less torque. It is torque that counts.
The ISE has a much larger volume grind chamber.
The ISE sink drain opening is about 1/2" larger. This means it is easier to push more and larger garbage into the disposer.
The ISE grinding dogs and grind chamber appear to be heavier material. Look inside each of them.
I think the ISE is worth the additional cost.

Pros: great
Cons: so far none

Only can say have had Waste King 1 hp gourmet since july 05
its still running like it should .
Has many advantages over ISE .
I've had 2 ISE'S both quit after 7 years just about the tine the warranty runs out .
Waste king -lifetime -inhome warranty
neck opening at sink opening is narrower than ISE , continous feed . Don't push the splash shield in to chamber any more .
Was always fishing for ISE'S splash shield from day 1 . Waste King was
much quieter , amazing . Plumber said install was quicker too .
Have disposed of all normal bones e.g steak , pork, chicken etc .
Do not do corn husks etc , no clams either .
Just a superior product so far , will know more in 7 years .
By the way ISE offered to replace my 2nd one , which was a replacement under warranty for the 1st one even though it was 76 months in use and over the 72 month warranty period .
The problem was the same for the 2nd as in the first .
Its just a good product .
