Choosing the Right Garbage Disposal at Lowe’s
Selecting the appropriate garbage disposal is crucial for a successful replacement. This section will cover the factors to consider when choosing a new unit, such as horsepower, features, and noise level. We will also explore the various brands and models available at Lowe’s, assisting you in making an informed decision.
- Horsepower: The horsepower (HP) rating indicates the disposal’s power. Higher HP generally means more powerful grinding and a better ability to handle tough scraps. A 1/2 HP unit is suitable for smaller households, while a ¾ HP or 1 HP unit is recommended for larger families or those who frequently dispose of large amounts of food waste. Consider your family size and disposal habits when making your choice.
- Sound level: Some disposals operate more quietly than others. Look for models with lower decibel ratings if noise is a concern. Insulation and proper installation can also affect the noise levels.
- Features: Additional features to consider include things like a “grind chamber” design, a built-in safety switch, or even a reverse function to clear jams. Consider which features would best suit your needs.
Disconnecting the Old Garbage Disposal
This section provides a step-by-step guide on safely disconnecting your old garbage disposal, including turning off the power, disconnecting plumbing, and removing the unit from the sink. We will emphasize safety precautions throughout the process to prevent accidents or injuries. It’s essential to carefully follow these steps to avoid leaks and damage to your plumbing.
Turning off the power
Before beginning any work, always turn off the power to the garbage disposal at the breaker box. This crucial step prevents electrical shock and potential injury. Failure to do so can be extremely dangerous.
Disconnecting the plumbing
Carefully disconnect the drain lines, both the inlet and outlet. Have a bucket or towels ready to catch any remaining water in the lines. It’s also helpful to label the pipes to aid in reassembly.
Removing the old unit
Once the plumbing is disconnected, the unit itself can typically be unbolted from the sink. You may need a wrench to loosen these bolts. Use caution and a steady hand to avoid damaging the sink.
- Turn off the power to the garbage disposal at the circuit breaker.
- Place a bucket under the disposal to catch any remaining water.

This includes correctly connecting the plumbing and electrical components, ensuring a secure fit, and testing the new unit. Correct installation is vital for proper functionality and longevity.
Connecting the plumbing
Reconnect the drain lines ensuring a watertight seal. Use plumber’s putty or Teflon tape to secure connections and prevent leaks. Make sure all connections are secure and tightly fastened.
Connecting the electrical wiring
Carefully connect the electrical wires to the new disposal, matching the wires appropriately and ensuring a secure connection. It is crucial to correctly match the wires to prevent any malfunction or potential hazards. Double-check your work before turning the power back on.

Troubleshooting and Maintenance
This section covers common issues you may encounter with your garbage disposal and provides solutions to resolve them. Additionally, we will discuss preventative maintenance tips to prolong the life of your garbage disposal and prevent future problems. Regular maintenance can significantly reduce the chances of encountering costly repairs or replacements.
Common Problems
- Jammed Disposal: A jammed disposal often occurs when a large or hard object is put down the disposal. Using the reverse function (if your model has one) can help clear the jam. If not, you may need to manually remove the obstruction.
- Leaking Disposal: Leaks often indicate loose or damaged connections. Check all the connections and tighten them as needed. If the leak persists, there might be a problem with the disposal itself requiring professional help.
- Disposal Not Working: If the disposal does not turn on, check the circuit breaker and ensure the power is turned on at the breaker box. Also, check the power switch. If none of these fix the issue, you may have an internal problem.
Preventative Maintenance
- Run cold water constantly while using the disposal to aid in flushing away scraps.
- Avoid putting down hard or large objects (bones, glass, etc.).
- Periodically flush the disposal with ice cubes and a handful of salt to help sharpen the grinding blades.
