Waste King A1SPC Knight Review

by Paul

WasteKing is mostly popular for their low price range garbage disposals. Consumers choose this brand for their low price range and good operation. Wasteking sells many powerful kitchen grinding devices at a range of small price comparing the other manufacturers.

Most of the products come with long term warranties. I am talking about another very powerful sink garbage disposal in a small price range from WasteKing. As usual, it comes with a lifetime warranty period, a powerful motor and consists of numerous important features.

If you are looking for a grinding monster to feed all your garbage from the kitchen, then this is a very good option that comes at a budget price.

Food & Grind Capacity

The Waste King A1SPC Knight is a continuous feed garbage disposal with a powerful 1 Horsepower Vortex magnet motor.

This motor runs at a speed of 2800 RPM that grinds up your kitchen waste into finest particles. You can put just anything from your kitchen waste and it will eat that up like a monster.

The one pass technology of wasteking sink garbage disposal claims more power than the other competitive disposers. So, if you are a big family with lots of people and you need heavy usage of a disposal regularly then you can go for this sink garbage disposal.

This is a high performing kitchen grinder that comes at a very minimal price comparing the other kitchen garbage disposals in the market.

Installing the Disposal

Snap and Lock Mounting System

Unlike the other garbage disposers from WasteKing the Knight A1SPc contains a snap and lock mounting system. This makes the installation much easier than the other disposers from Waste King.

There is a problem with the size and weight of this Waste King disposal. As it is a big and heavy unit, you need more than one people to install it. When you go for snap and lock part the weight of the unit will be a problem if there is no one to help you. Otherwise, you can simply use a stack of wood or jack to hold the disposal close to the installation height.

Other than the weight you just need to go follow the instructions to install the unit properly. Waste King already provides the power cord with their disposal units, so there's no need to worry about buying anything extra.

Safety & Durability

This sink garbage disposal contains stainless steel grinding components that provide the guarantee of no corrosion and rust.

When the chance of corrosion and rust is small the chance of internal parts breakage is naturally reduced. Also, the high power grinding motor ensures your waste is cut into smallest pieces that will not clog into your drainage pipe and create any mess.

Noise Expectations

I will not suggest this sink garbage disposal to those who are looking for the most silent kitchen garbage disposal in the market.

Simply because this fella is not that quiet. You will experience some noise due to the powerful grinding operation when you put the bones or hard food waste into the chamber. But that sound is a low-frequency kind of sound rather than unpleasant motor noise.

Also, I’ll remind you that you are spending nearly $150 less than the other units available in the market from other brands to have this amount of power from a sink garbage disposal. I think the sound level is a good trade off over the cheap price.

Weight & Size

I have already mentioned the weight and size issue. This is a reasonably big unit with a dimension of 8.8 x 8.8 x 15 inches with a weight of 18.04 pound which is heavier than most of the waste king disposals.

But the size is not that big to not fit under a regular kitchen sink. You just need to check if you have enough space under your kitchen sink to put this unit.

Waste King Warranty

You get the warranty of a lifetime of the real purchaser from Waste King with this garbage disposer. This warranty covers a lifetime corrosion warranty and limited mechanical warranty.

That means if you have a problem with your disposal’s material or mechanical defect then Waste King is going to give you a free in-home replacement free of charge. Get the best price on amazon!

Waste King L-8000 VS A1SPC Knight

Waste King A1SPC Knight

Waste King A1SPC

Many people ask me about the difference between Waste King L-8000 and Waste King A1SPC Knight. I recommend both from those who are looking for a powerful unit at a low range.

The main difference between these two units is the design. The outlook of 8000 is as like as the usual waste king sink garbage disposal where the A1SPC have a different looking color and design.

The two devices contain two different types of mountings. L-8000 has an EZ mounting system where A1SPC Knight has a snap and lock mounting system. Both devices are same in terms of power and operation.

The noise level of A1SPC Knight is comparatively lower than L-8000. You need to spend 25 dollars more for A1SPC Knight than L 8000. Now you can choose one of them in terms of your necessity.
