Gathering Your Tools and Materials
- Basin Wrench: This specialized wrench is essential for loosening and tightening the disposal’s mounting nuts under the sink.

Safety First: Power and Water
Always prioritize safety! Before beginning any work, turn off the power to the disposal at the circuit breaker. Also, turn off the water supply to both the hot and cold water lines leading to the disposal. Failure to do so can lead to electric shock or water damage.

Knowing your Insinkerator model number is vital for ordering the correct replacement part and ensuring compatibility. This number is usually located on a sticker on the unit itself. Finding this information early saves time and potential return trips to the store.
- Check the bottom or side of the unit for a sticker containing the model number.
