Test for Leaks — Install the New Garbage Disposal Unit

Leaky Garbage Disposal Repair: Bottom Seal Replacement Guide · Step 3 of 3
In this video
Plug the garbage disposal's power cord back into the outlet. To perform a thorough leak test, place a sink stopper in the drain and fill the sink basin with a good amount of water. Once filled, remove the stopper and let the water flow through the new splash guard and disposal. While the water is draining, look and feel carefully around the mounting ring and all reconnected pipes underneath the sink to ensure there are no drips or leaks.
Goal: Verify the installation is watertight
- Testing with a large volume of water creates pressure and is the best way to reveal any small leaks.

FAQs
Why is it so crucial to disconnect the power at the breaker or outlet before starting this repair?
Disconnecting power is the most critical safety step to prevent severe electrical shock or injury while working with the unit. Always verify the power is off at the breaker or by unplugging the unit directly before touching any wires or plumbing connections.
Is a basin wrench truly essential for this project, or can I use regular pliers?
A basin wrench is highly recommended as it's specifically designed to reach and loosen the nuts in the tight, awkward spaces under the sink that regular pliers often cannot access. While pliers might work for some visible nuts, a basin wrench will make the job significantly easier and help prevent stripped fasteners.
As a beginner, how confident should I be about completing this within the estimated 3 hours, and what if I'm not familiar with plumbing?
This project is rated 'beginner' because it primarily involves disconnecting and reconnecting pre-existing parts, not complex plumbing theory or pipe soldering. The 3-hour estimate accounts for potential learning curves, gathering tools, and careful testing, making it achievable for most first-timers if instructions are followed diligently.
What are the most common reasons a new garbage disposal might leak immediately after installation, and how can I prevent it?
The most common causes for leaks are improper sealing around the sink flange or loose plumbing connections. To prevent this, ensure you apply a generous, continuous rope of plumber's putty around the sink flange before seating the disposal, and meticulously hand-tighten all pipe connections before a final quarter-turn with tools.
