Garbage Disposal Do’s and Don’ts for Sun City West Homeowners
Kitchen drain calls are the number one service request we receive in Sun City West. Many homeowners assume the disposal can handle whatever goes into the sink, but older Arizona drain lines tell a very different story.
Your Garbage Disposal Is Not a Trash Can
Garbage disposals are designed to handle tiny scraps of soft food left on dinner plates after scraping - not full portions of leftover meals or fibrous vegetable peelings. When heavy waste enters a 1980s kitchen drain line, it quickly turns into a dense paste that clings to mineral-scaled pipe walls.
The "Never Put Down the Drain" List
Coffee Grounds: Grounds do not dissolve in water. Instead, they settle in the low trap and combine with grease to form a thick, sludge-like dam.
Eggshells: The membrane lining of eggshells wraps around disposal shredder rings, while the granular shell creates heavy sediment in the P-trap.
Potato Peels & Celery: High-starch foods create a sticky glue when ground up, while fibrous strings from celery and artichokes wrap tightly around the motor spindle.
Cooking Oils, Fats & Butter (FOG): Liquid when hot, but grease solidifies the second it touches cool underground pipes, creating massive blockages.
Pasta & Rice: Grains expand when soaked in water, swelling up inside your drain line hours after you wash dishes.
How to Unjam a Stuck Disposal Safely (DIY Guide)
If your disposal hums but does not spin when you flip the wall switch, turn the switch off immediately to avoid burning out the motor:
1. Cut the power: Unplug the disposal under the sink or turn off its breaker in the main electrical panel.
2. Check the bottom: Look under the disposal unit for a small hex socket in the bottom center.
3. Use an Allen wrench: Insert a 1/4-inch hex wrench into the socket and work it back and forth until the blades turn freely 360 degrees.
4. Reset: Press the red thermal reset button on the bottom, plug the unit back in, and run cold water before testing.

Should I run hot or cold water when running the disposal?
Always run cold water! Cold water keeps any incidental fats solid so the blades can chop them into fine particles rather than melting grease down the drain.
How can I keep my disposal smelling fresh naturally?
Grind small lemon or lime wedges with ice cubes and a splash of white vinegar. The ice sharpens blades and knocks off slime, while citrus oils deodorize.
What should I do if both sides of my double sink back up?
That indicates a blockage past the P-trap in the wall pipe. Avoid running the dishwasher or disposal and call for professional clearing.
