Question: i have a whirpool... can the 9920 replace my old whirlpool gc 2000
Document: The Waste King 9920 was Easy to install. I worked with my neighbor who as like me had never put in a garbage disposal. Between the 2 of us we where able to install the 9920 with ease. It is quieter than the old one that was broke. It has less power but i have not noticed any difference. I would recommended this to any one that needs to replace a faulty garbage disposal or just wants to get one for their sink.
I purchased this to replace a Waste King 1/2 hp that I had installed in 1996 when I built my house. Installation took about 20 minutes. This is a much quieter version than the 15 year old unit. If it lasts half as long as the first Waste King, I'll be pleased. Highly recommended.
It comes with a 2 year warranty on the 9920 model, and it appears very simple to get warranty service. I highly recommend this as a cost effective replacement unit.
Got a Waste King 9920 1/2 HP recently. Great product; works very well. Best of all, they have great customer service. I called the 800#, and they answered several questions. They were great.
I ordered the Waste King 9920 Legend Series 1/2 HP Disposal from Amazon after our existing Badger 5 got &#34;stuck&#34; and would no longer function. I read the reviews and agree with most in that the installation was very easily done and the unit operates fine. The only review I disagree with is not &#34;all&#34; items required for installation are included.
This disposal unit replaced a 1/2 HP unit that died. This unit was very easy to install and has performed flawlessly. It was the first time I had to replace a garbage disposal unit and I was impressed by the ease of installation!
I bought this to replace a similar disposal I purchased from Home Depot about 10 years ago. This is really a good disposal. It grinds just about anything and is a very quiet unit. I have it attached to a stainless steel sink and you hardly hear it when it's operating.
We think it works but we are going to replace it after 3 months, with an "In-sink". The 1/2HP motor works but we do not hear a grinding sound. It vibrates our base cabinet, and sink drain always drains slow. Drain stopper is hard to lock in place. We think our model has a defective grinder and the large motor is simply sucking everything down.
I purchased it to replace Badger 5, which rusted out after less than 3 years of service. Waste King arrived and was already assembled as it appears on the Amazon photo - with Sink Flange stuck inside the unit. To start the installation, one has to remove it. I simply was not able to do that and I did not give up early. I tried for ~1 hour to remove it.
And it's dead quiet compared to other disposals I've used so that's nice.Also credit to Amazon. I'm a total cheapskate. So even tho I needed this to replace a leaking disposal I choose super saver shipping prepared to deal with the leak for a couple of weeks to save a few more bucks but it arrived in a shocking 2 business days.Conclusion: If you want a disposal that can destroy anything you throw at it. Get something more powerful.
