Step 1 · Prepare the Work Area and Shut Off Power
Begin by completely clearing out the cabinet under the sink to create ample workspace. Place a bucket directly under the P-trap and garbage disposal. Lay down several old towels around the bucket to absorb any spills. The most critical safety step is to disconnect the power to the disposal. Locate the power cord and unplug it from the wall outlet. If your unit is hardwired, go to your home's main electrical panel and switch off the circuit breaker that controls the garbage disposal. To be certain, use a non-contact voltage tester to verify that there is no electrical current flowing to the unit before proceeding.
