How To Change Garbage Disposal

Changing a garbage disposal may seem like a daunting task, but with the right guidance and tools, it can be a straightforward process. Whether you are replacing a faulty unit or upgrading to a new one, the following steps will help you navigate through the installation process smoothly.

Understanding the Garbage Disposal

Before you begin the installation process, it is essential to familiarize yourself with the components of the new garbage disposal. Take the time to understand how the parts fit together and ensure that you have all the necessary tools and materials for the installation.

If your existing disposal seems to be malfunctioning, try a few troubleshooting steps before proceeding with the replacement. Look for any obstructions or jams that may be hindering its operation. You can also attempt to manually rotate the motor or reset the unit to see if it resolves the issue.

Disposal System Anatomy

Understanding the anatomy of the disposal system is crucial for a successful installation. If you have a double sink, it is recommended to run the discharge tube directly to a tee below the opposite sink. Additionally, ensure that you remove the dishwasher knockout before installing the new unit to prevent any potential issues.

Supporting the Weight

Garbage disposals can be heavy, so it is important to have proper support when removing or installing a unit. Assemble a support system using a paint can and scraps of wood to ensure that you can handle the weight of the disposal effectively.

Preparing for Installation

Before you begin the installation process, make sure you have the necessary cord and discharge tube for the new disposal. Reusing the old discharge tube can save you a trip to the store, but ensure that it is the correct length for the new unit. Additionally, consider keeping the old sink flange if it is undamaged and fits the new disposal properly.

Installation Process

Once you have prepared the necessary components, it’s time to start the installation. Begin by removing the old disposal and mounting hardware, and carefully inspect the plumbing for any signs of leakage before proceeding with the installation. Use silicone for a reliable seal when securing the sink flange to the sink, and ensure that all connections are tightened securely to prevent leaks.

Testing and Finalizing

After completing the installation, it is crucial to test for any leaks at the sink flange, dishwasher, tail-pipe, and mounting assembly connections. Once you have confirmed that everything is in place and secure, turn on the electrical breaker to test the operation of the new garbage disposal.
