Waste King L-3300 Legend Series 3/4 HP Continuous Feed Operation Garbage Disposer

Silent Operation

Nobody wants a garbage disposal that is overly loud and annoying. This is why the Legend 3300 is such a good investment. Although you will be able to hear the unit’s powerful motor, you won’t have to worry about disturbing the neighbors. The grinding chamber is completely insulated to help prevent noise from escaping. This will provide you with a near silent grind that your loved ones could sleep through.

Fewer Jams

It is undoubtedly true that Waste King has gone above and beyond to ensure their products will withstand the test of time. Of course, all garbage disposals can run into problems. One of the most common problems is the jam. If your disposal becomes jammed, it could possibly damage the motor and you won’t be able to use the appliance, until the clog is cleared.

Waste King has implemented the use of stainless steel swivel impellers to help decrease the likelihood of clogs. At the same time, this disposal features an overload protector to help keep the motor safe. When the disposal is overloaded, it’ll automatically shut off. When you’re ready to use it again, just hit the manual reset button.

Sink Flange

One of the most important components of the garbage disposal is the sink flange. If the flange isn’t up to par, the disposal will not securely attach to the sink and this could lead to leaks. The good news is that the L-3300 Disposal has a sink flange, which is manufactured from stainless steel and Celcon. The combination helps to ensure that leaks are prevented and that the disposal will remain firmly secured to the sink at all times.

Grinding Components

A garbage disposal’s longevity will depend on the components, the motor, grinding blades and chamber. If these components are lacking in design, they will not endure normal operating conditions. Taking a closer look at these components, embedded into the L-3300, you will immediately notice the materials utilized in their construction.

When you think of stainless steel and glass-filled nylon, you immediately think of durability. These materials are rust resistance to prevent corrosion buildup, even after many years of use. Corrosion will not only damage these crucial components, but will also prevent them from operating efficiently. Another important factor to consider is whether or not these components are insulated.

In order to keep the operation noise levels to a minimum, the grinding components must be insulated properly. The Waste King 3300 is designed to perfection and with the insulated grinding components. You can rest assured that the unit will not disturb the other family members, while they are studying or watching TV.

Septic Tank Friendly

Older garbage disposal models were not compatible with septic tanks. The main reason for this was because the food wastes were not ground down to the finest consistency. As you well know, medium and large sticky food particles will potentially clog your drainage system. The modern L-3300 Series is compatible with septic tanks. All food introduced to the unit must undergo an extensive grinding process. The byproduct of these wastes will be nothing short of a liquidly consistency.

Additional Items

When you purchase the Waste King L-3300, you receive a total package. Everything that you need to install the unit and get it up and running will be included right in the package. Of course, this is assuming that you are just replacing an existing unit. If you are doing a complete new install it is possible that you may require a few more tools and materials, because you might have to run a, electrical wire to supply an outlet. When you purchase the product you will receive the disposal, power cord, mounting hardware, and detailed instruction booklet.

The L-3300 unit comes with a 36” electrical cable. This may seem like a small detail, but it could be really important. In fact, it could be the difference in spending extra money on additional parts. For instance, every disposal operates on an electrical power source.

This means that you need an electrical outlet to plug into. If there is not one of these within the vicinity, you are going to have to run an electrical wire and install a new outlet. If you are not familiar with how electricity works, you are going to have to hire a licensed electrician, this can be rather expensive. The extra-long 36” electrical cord may just be able to save you a lot of hassle in the long run.


One amazing thing about this unit is that it is backed by a 10-year in home warranty. An in home warranty is much more than just a regular warranty. In the event that in the first 10 years of owning the unit it develops a defect the company will send out a tech to replace the unit for free.

You do not even have to pay for labor charges, which is pretty amazing when you think about it. If something is going to go wrong with your unit it will most definitely happen within the first 10 years. It should also be noted that this is one of the longest warranties offered by any disposal manufacturer. On top of all of this, the unit also comes along with a lifetime warranty that against corrosion. If your unit ever breaks down due to corrosion, it will be replaced for free by a professional technician.

Continuous Feed

This unit is also a continuous feed unit, which means it will continue to run from the minute you turn the unit on until you turn it off. This type of operation provides several benefits in certain situations. If you have a large amount of waste a continuous feed is by far the most effective option.

You never have to wait until the chamber is full before the power comes one. This also means that you will be able to keep a much cleaner kitchen. While preparing dinner or breakfast you can just throw the waste down the sink, turn on the disposal, and it will grind it right up. On top of this, continuous feed disposals are much cheaper when compared to batch-feed models.

Splash Guard

Although garbage disposals are fairly self-explanatory, they do require a little bit of maintenance from time to time. In order to extend the longevity of your disposal and to maintain optimum performance, it is essential to clean the unit as frequently as possible.

Unfortunately, some disposals are much more difficult to clean than others. The L-3300 falls into the easier end of the spectrum.
