1. Free the clog.

Use a plunger or plumber's helper to free the clog. If you have a double sink, place a stopper to block off the other sinkhole opening.

2. Fill the sink with four inches (10cm) of water.

Fill the sink with four inches (10cm) of water. Place the plunger over the garbage disposal opening and press down slowly and gently. Then, pull the plunger upwards quickly using your strength. Repeat this pulling action several times.

3. Clear the garbage disposal of any debris.

When the clog is dislodged, run the water and the garbage disposal for a minute or two.

Tips For Success

  • Avoid using hot water when grinding food waste. It is OK to drain hot water into the garbage disposal between grinding periods.
  • Never pour grease or fat into your garbage disposal or drain.
