Choosing the Right Garbage Disposal
Selecting the appropriate garbage disposal is crucial. Consider your needs, such as the frequency of use and the types of waste you’ll dispose of. Factors like horsepower and grind chamber size impact performance. Research different brands and read reviews to make an informed decision.
- Horsepower: Higher horsepower means more power and better grinding ability. A higher horsepower model may be needed for frequent use or for households that produce a lot of food waste.
- Grind Chamber Size: A larger grind chamber can accommodate more waste, reducing the chance of jams and clogs. Consider the size of the food scraps you typically dispose of when making your selection.
- Sound Level: Some disposals are quieter than others. Consider how much noise you’re willing to tolerate, particularly if your kitchen is open to other living areas.
Gathering Necessary Tools and Materials
Having the right tools at hand streamlines the installation process. This list includes essential tools and materials. Some tools can be substituted, but having the recommended tools makes the process much easier.
- Adjustable wrench
- Basin wrench
- Pliers
- Screwdrivers (Phillips and flathead)

- Slip joint pliers
Preparing the Sink for Installation
Before you begin, ensure the sink is clean and dry. Turn off the water supply to the sink, either at the shut-off valves under the sink or at the main water supply. This crucial step prevents leaks and water damage during the installation.
