To come to Jerrods' defense, he is a long time member of this forum and provides very valuable information. The price for the Waste King is really low and half the regular price anywhere else from Costo. That is a really good deal. I recently purchased a Franke GD which is made by Waste King also. I have not installed it and therefore cannot tell you how it works. I was recently at a friends who had the top of the line Evolution series installed and it was really quiet. I may return the Franke and get the InSinkerator although it is more expensive. For $99 from Costo, I don't knmow if you can really go wrong with the Waste King. If you get it and don't like it then you can always return it to Costco. Good luck!

Hi arbordomus, I understand your problem, ISE flanges and accessories seems to be much more common. Good job getting the top parts changed out. I called Waste King and they told me the strainer is 4009. It is available in stainless; it can also be used as a stopper. This item will work on the original Waste King 3 bolt flange in my picture. I hope this helps anyone who bought this Disposer 9980 recently. I don't like to see the rubber splash guard and trying to avoid utensils falling in. Forgot to say the Disposer 9980 has a Lifetime in home warranty. I have written the serial number from the bottom onto the body of the disposer, since I can't read it after the installation. The WK has a higher RPM motor (2800 RPM) than the ISE (1725 RPM). But it will slow down when grinding to increase torque, at least that's what the manual says.

Any adivse on purchasing a Waste King 3300 or an Insinkerator Essential. Is one quieter then the other or will one last longer then the other? thanks,

Anita, that's too bad that your disposal isn't working as well as you'd like. I guess on the bright side, it has a great warranty, and as a percentage of your total kitchen re-do (SO gorgeous BTW!), it's not so much $$ invested. In my home growing up, we had a batch feed disposal, and it was the only kind I knew until I moved out of the house. I had a rental apartment once with a continuous feed disposal. I never really got used to it, but it's hard to change habits that formed from childhood. In my home now, I have the Kitchenaid 1 hp batch feed, which is actually made by Insinkerator (in their factory in Wisconsin). I think though, that the type of disposal someone prefers is personal taste and how s/he likes to work in a kitchen; there is no right or wrong choice. I agree with Buehl that one of the continuous feed's advantages is that you just feed the disposal continually which is convenient (although my disposal's chamber is so large, I rarely have to run it more than once). A disadvantage of a batch feed is that it takes up A LOT of room under the sink. Having said that, I do feel that the "ick factor"--and this is just MHO--is greater with the continuous feed style cause of the clammy flange. You are either having to push food through the flange with your hand or a utensil (I guess Waste King has a tool just for that purpose), or slide your wrist past its clammy surface to fish something out. Regarding brand, I used to say that Waste King was really great, but I think they have changed recently. About 1-1/2 years ago Waste King moved their manufacturing from the U.S. to China. That likely enabled them to lower their costs significantly to be able to sell a disposal at Costco for $79 when that same model when made in the U.S. used to sell for $179. In that same vein, Waste King used to have an entire page on their website devoted to the fact that their disposals are septic-tank safe. That page is no longer on their website, perhaps because the China-made disposals can no longer do that. There are people on this forum who love their Waste Kings, but I bet they have the older ones that were made in the U.S. Anita, my advice to you is that if your Waste King disposal is REALLY bothering you, switch it out for the Insinkerator Evolution Essential which is also a continuous feed style. Donate your Waste King to Habitat for Humanity, or sell it on Craig's List. I am saying this because you are going to be using the disposal every day, likely several times a day, and if you hate it, why ruin the experience of your lovely new kitchen with an irksome disposal. You already have the switch hook-up, so it wouldn't make sense to change to a batch feed style, and the Insinkerator is a well-made model, and quiet too. Just my $.02.
