The 9940 model seems to be unlisted on the Waste King’s website, but it is still currently available from Amazon.
Similar to the lower power Waste King 9930 model, the 9940 has all stainless steel grinding components so you can expect a long life out of this disposal. Waste King even provides an 8 year warranty, which is one of the longest warranties provided by any garbage disposal manufacturer.
The 9940 is a continuous feed disposal with a 3-bolt mount. Everything you need to mount the disposal is included with it. You will, however, need to have some Plumber’s Putty on hand to put around the sink flange to ensure a water-tight seal. With that said, all the parts are included.
One difference, aside from power, from the 9940 and the lower models (9910-9930) is that it has some sound insulation to help reduce noise.

Continuous Feed vs. Batch Feed
There is no performance difference between the batch feed and continuous feed disposals. Continuous feed is the most commonly used type, and is activated by a wall switch. You simply feed food scraps in as you run water down the drain and activate the switch.
In case you’re not familiar with batch feed, you load the disposal with food scraps then use the stopper to activate the disposal. This means the drain is closed before the disposal will activate and nothing else can enter the disposal except water that’s allowed to flow through the stopper. You can see how this would be safer with kids around as no hands can enter the disposal once it has been activated. When you remove the stopper the disposal automatically cuts off.
The Waste King 9940 is a continuous feed, but if you’re looking for a batch feed Waste King puts a “TC” at the end of their name. Check out the Waste King 9900TC for a 3-bolt mount type batch feed.
Is 3/4 HP enough power?
Most disposals installed into apartments, for example, are 1/3 HP. I use mine every day and have no trouble grinding vegetable scraps and meat trimmings. You will have no trouble from a 3/4 HP disposal. The extra power isn’t much more expensive than the 9930.
Note: Here are the official recommendations by Anaheim Manufacturing Company (they make Waste King disposals).
“All types of food waste can be put down your disposer such as vegetable peels, fibrous materials, small bones, fruit pits, etc. Make sure when you do grind materials that you run lots of water through the sink while the unit runs. Items that you SHOULD NOT put down your disposer include large whole bones, clams, oyster shells, whole corn husks, glass, china, plastic, bottle caps, tin, aluminum foil, utensils, caustic drain cleaner, hot grease, or other hot liquids.”
Installation & the 3-Bolt Mount System
First, a little bit about the 3-bolt system compared to the EZ Mount. Though Waste King says there isn’t any difference between the durability of the two mounting systems, the 3-bolt system is made of stainless steel whereas the EZ mount is made of aluminum and plastic. There are fewer steps to install the EZ mount system, but don’t let that be the deciding factor since this is an install, if done correctly, will only need to be done once. It isn’t that difficult and if you prefer the stainless steel then don’t let the mounting difficulty sway your decision. Also, the splash guard for the 3-bolt system is not removable, which for most people doesn’t seem to be an issue.
There are a few things to be aware of before you do the install.
- You need Plumber’s Putty. It goes around the sink flange to ensure no leaks occur. Some guides completely miss this step and it is one of the easiest places for a leak to occur.
- You should have a standard 3 pronged outlet in place under your sink.
- If you have a dishwasher, you attach the dishwasher discharge hose to a designated port on the side of the disposal. You must knock out the plug in this port before attaching. DO NOT knock out the plug if you won’t be attaching a dishwasher hose.
- It’s easier to install the drain pipe onto the unit before attaching to the sink.
The power cord should come already attached to your Waste King disposal. Many other disposals don’t even come with the cord, but this helps ensure you don’t end up with wiring issues that fry your disposal.
The dimensions of the 9940 are 7 3/4″ diameter and 13 5/8″ height. Notice it is about an inch wider than the lower models. This is due to the larger motor and sound insulation.
