Waste King 9940 3/4 HP Continuous Feed Garbage Disposal Review

The Waste King 9940 is a very popular garbage disposal unit and it is easy to see why.  It is a well know brand in the United States that is known for great quality control.  They have been a trusted name in the industry for many years.  We will go over what we think are the best features of this kitchen disposal unit and if it’s worth it for you or not.

Features of the Waste King 9940

The main selling point of this disposer has to be the powerful 3/4 HP motor.  The motors top speed is 2700 rpm, or 2700 rotations per minute.  This makes it one of the strongest disposers if you look at the “power per pound”.  The motor is strong enough to grind up almost any food waste that you put down the drain.

This disposer uses the continuous feed method which means that you can add waste while it is running.  No more having to start and stop just to add more garbage!  It is easy to clean because of a removable splash guard and jamming frequency is massively reduced with the stainless steel swivel impellers.

You don’t have to worry about the grinding chamber on the 9940 corroding and rusting either.  This is made possible because it is made of a glass filled polyester material which resists corrosion by quite a bit.

Ever have a noisy garbage disposal unit?  You don’t have to worry about that with this one because the stainless steel components are insulated.  This allows for a grind that is quieter than a lot of other models.

If you have a dishwasher then one thing you can do is to hook up the garbage disposal to it.  You can use a screwdriver and hammer to take out the plug and connect it.  This enables the dishwasher to pump the discarded food waste and water into the disposal unit to be grinded up.

Another bonus that is offered by Waste King with this disposal is the awesome warranty.  You can read more about it at Amazon.
