They are good for 1-2 people household. They do save few bucks but won’t be beneficial if it results in frustration.

1/2 Horsepower

This is somewhat powerful than the 1/3HP and limited to use for maximum 2-3 people where usage in the kitchen is low. Try to find stainless steel grinding components which will definitely ensure the long life of disposer.

3/4th HP

A house with 4-5 people needs this garbage disposal model with 3/4HP.You might see this model common in this modern era. These models feature most sound damping features which reduce the level of noise a disposal makes when compared with it’s lower power units.

1 HP

This model is good for a large family which generates a large amount of waste in the kitchen, It’s hard enough to handle bones and tough waste without being jammed like other models. So for this type of garbage you need to install 1HP garbage disposal in your home.

The recommended way is to spend money on the highest power model to get the best results but only if you can afford it. If short on budget and family is small go with lower tier models but you should expect poorly ground waste to clog your pipes more frequently compared with higher-end models.

Garbage Disposal Switches & Connections

The latest garbage disposals are designed in a way to dovetail with a sink’s drain outlet and the two connecting ends will connect simply. Also, you have options to get a number of adapters and kits available for connections.

You will see a switch with a continuous feed model which is generally mounted on the wall nearby. Sometimes, an air pressure switch will be mounted on the countertop. The safest is the air pressure switches then traditional flip switches as they guard against shocks by simply isolating the electrical system far away from the sink’s source of water. On the other hand batch, feed garbage disposals don’t require any installation or don’t use a switch. Safety codes in your community will let you know how far the electrical switch should be located from the sink.

Quiet Garbage Disposal

It’s common sense that the heavier and bigger a model is the more quietly that garbage disposal will work, so long as it fits exactly underneath your sink. Even though from the last 10 years many changes have been seen in the sound damping technology in the design of garbage disposal. It might be unrealistic to expect that your garbage disposal will operate noise-free.Some disposals will be noisier under specific sinks due to the amount of vibration they generate. So you should always look for a garbage disposal which features a nylon, insulated grinding chamber which is in WasteKing.

Garbage Disposal Warranty

While buying the best garbage disposal for your home the most important thing which requires your attention is the manufacturer’s warranty of garbage disposal.
