5 Habits That Double the Life of Your Garbage Disposal

Garbage disposal and under-sink drain piping

A quality garbage disposal should last 10-12 years. The ones we replace at year four all died the same handful of ways — and every one of them is preventable for free.

The five habits

One: run cold water before, during, and 15 seconds after grinding — cold keeps any grease solid enough to chop and flush instead of coating the chamber. Two: feed it gradually instead of packing the chamber and flipping the switch. Three: keep fibrous and starchy loads out — celery, corn husks, onion skins, potato peels, and coffee grounds either wrap the impellers or settle into drain-clogging sludge.

Four: never pour grease in it. The disposal chops; it does not make grease disappear — that happens twenty feet down the line where it congeals. Five: grind a tray of ice cubes monthly. It knocks buildup off the grind ring and is the only 'cleaning product' the machine needs.

Humming, leaking, or tripping?

A hum with no spin is a jam — never reach in; use the hex key in the bottom-center socket and the red reset button. Leaks from the bottom housing mean the internal seals are gone and replacement is the honest answer. Leaks at the top flange are repairable. If your disposal trips the reset more than once a month, the motor is on its way out — replacing it on your schedule beats replacing it during Thanksgiving cleanup. (254) 366-8281.
