Waste King 9940: Design & Installation

Let us start from the dimensions, as it is one of the main distinguishing features that set these two models apart. Waste King 9940 is the smaller and lighter model of the two. This model measures 7.75″ in diameter and 13.625″ in height. However, compared to most competitors in the market, this model is somewhat wider due to having a bigger motor and a special sound insulation.

Because of the smaller size, Waste King 9940 has a better chance to fit under your sink if there isn’t much space available in the area. However, space availability is usually not an issue, as sink installations tend to have plenty of space underneath them to allow plumbing work.

Unlike the lower models which rely on the EZ Mount installation system, Waste King 9940 comes with a 3-bolt design. Although EZ Mount involves fewer steps to set-up, you should not let that become the only deciding factor. The 3-bolt installation is way more durable. It is made of stainless steel as opposed to EZ Mount’s aluminum and plastic. Besides, if done correctly, you will only deal with the 3-bolt installation once for the entire lifetime of the unit.

There is a 36-inch power cord that comes attached to Waste King 9940. This is a nice feature, as many other models often come without any power cord. The power cord should be long enough to reach a power outlet that isn’t too far from your sink, but you can use an extension cord if there isn’t any nearby.

Waste King 9940: Features

The next difference between Waste King 9940 vs 9950 is the warranty. This model is ‘only’ backed by an 8-year warranty. Well, as a matter of fact, Waste King 9940 is already one of the models with the longest warranty terms available in the market. But the title of the longest warranty should go to Waste King 9950, which is backed for 10 years.

One feature of Waste King 9940 that makes it superior compared to other garbage disposal units in the market right now is the sound insulation. This feature enables Waste King 9940 to work very quietly, even though the motor is actually very powerful and the cutting speed is much higher than the average of the other models.

The next thing that you need to know about Waste King 9940 is that it is a continuous-feed garbage disposal. This is the most common type of garbage disposal. It is simply activated by a switch; it will continue running as long as it is turned on and you feed food scraps with water through the drain. This is a convenient design because you won’t need to repeatedly close and open the drain.

The other type is the batch-feed garbage disposal, which requires you to load the unit before using the stopper to close the drain and activate the unit. In this case, nothing can enter the unit once it starts running. If you remove the stopper, the unit will automatically shut off. Performance-wise, there is no difference between continuous feed and batch feed, but the batch-feed design is usually preferred when extra safety measure is needed, for example when there is a kid around the house.

The build quality of Waste King 9940 is very good. In addition to the stainless steel 3-bolt mount, it also features stainless steel impellers, grind ring, and turntable. The grinding chamber is constructed from corrosion-proof glass-filled polyester. The splash guard is not removable, but this is not an issue at all.

Waste King 9940: Performance

In terms of power, Waste King 9940 vs 9950 are similar. These two units are way more powerful than most other models in the market. While the average garbage disposal unit is usually armed with a 1/3 HP motor, each of these units comes with a 3/4 HP motor with a cutting speed rated at 2,700 RPM.

Even the average garbage disposal unit is already powerful enough to deal with common food waste like vegetables and meats. However, with a fast and powerful motor like that of Waste King 9940, you can be certain that you will never need to deal with clogging. It can easily cut harder objects like bones, and the high speed will ensure that the waste is shredded into fine pieces.

As mentioned above, Waste King 9940 works very quietly. However, this model seems to produce slightly more noise compared to Waste King 9950. Most probably, the cause of such a difference is the thinner sound insulation on Waste King 9940. But, then again, most people won’t notice the difference at all.

Waste King 9950: Design & Installation

Now, we will take a look at Waste King 9950. It is a newer model, and it comes with some improvement. In terms of size, this model is about an inch larger than Waste King 9940. It measures 8.5″ in diameter and 14.5″ in height. The increased dimensions apparently come from the bigger grinding chamber and the thicker sound insulation.

Nevertheless, Waste King 9950 is quite similar to Waste King 9940 as it also comes with a stainless steel 3-bolt installation system. Although this system is not as simple as the EZ Mount on the lower models, this system is much more durable and will not require fixes or adjustments once done correctly.

There are several things that you need to pay attention to when working with the 3-bolt installation system.

  • First of all, you need to run some plumber’s putty around the sink flange to prevent leaking.
  • Secondly, if you want to attach a dishwasher discharge hose to the garbage disposal, you need to knock off the plug in the side port of the garbage disposal and attach the dishwasher discharge hose here (if you are not going to connect a dishwasher, you should not knock off this plug).
  • Thirdly, you will find it easier to connect the drain pipe to the garbage disposal before attaching them to the sink.

Waste King 9950 is also equipped with a 36-inch power cord. It will be very convenient if you already have a three-prong power outlet under the sink, as this will render an extension cord unnecessary.

Waste King 9950: Features

When choosing between Waste King 9940 vs 9950, you may want to consider about their warranty terms. So far, Waste King 9950 is the garbage disposal with the longest warranty in the market.

It is backed by a 10-year warranty, which is more than twice longer than competing models from General Electric and InSinkErator. Obviously, the manufacturer is very confident in the quality and durability of this product.

Aside from the longer warranty, the feature set of Waste King 9950 is similar to that of Waste King 9940. It comes with a corrosion-proof glass-filled polyester grinding chamber, stainless steel components, and a non-removable splash guard.

Just like its sibling here, Waste King 9950 is a continuous-feed garbage disposal. Which means, it will continue running as long as it is turned on. This will allow you to feed waste continuously even after the unit has started running. A batch-feed unit, on the other hand, will not allow anything besides water to enter when running.

Waste King 9950: Performance

Waste King 9950 is also armed with a 3/4 HP motor with a cutting speed of 2,700 RPM. It is very powerful and very fast. It is very much capable of chopping down food scraps into fine pieces.

Property management companies usually use cheap 1/3 HP garbage disposal units in their projects. The problem with a low-powered garbage disposal is that it may struggle with harder objects like bones and wooden pieces. Also, it may lack the speed to shred the waste into fine pieces. If the pieces are not fine enough, they may cause clogging.

Waste King 9950 is more than twice more powerful than the average garbage disposal. It will give you some peace of mind from clogging issues. Despite the great power, Waste King 9950 works very quietly, thanks to the sophisticated sound insulation.
