How Do Garbage Disposals Work?

Garbage disposals are small but mighty kitchen tools. Installed under your sink, they use spinning grinders — often called lugs or impellers — to break down food waste. It turns food into tiny particles that can safely flow through your plumbing. While convenient, disposals aren’t designed to handle everything. When misused or overworked, they can leak water, jam or wear out over time.

At Oasis Plumbing, Heating & Air Conditioning, we provide expert garbage disposal repair and installation services for homes across San Marcos and San Diego County. Whether your disposal is clogged or needs an upgrade, we’ll help get things running smoothly again.

Causes Of Garbage Disposal Clogs

Some items simply don’t belong in your disposal. Here are a few of the top offenders we find during service calls:

  • Fibrous vegetables (like celery or corn husks)
  • Coffee grounds
  • Grease, fats or cooking oil
  • Eggshells
  • Fruit pits or bones
  • Pasta, rice or bread that expands with water
  • Shot glasses or silverware accidentally dropped in

When in doubt, throw it out — or call Oasis to safely clear the clog.

When To Schedule Garbage Disposal Repair

You rely on your garbage disposal daily. When the kitchen plumbing fixtures start acting up, it can impact your entire culinary routine. It’s time to schedule a repair if you notice:

  • A humming sound without the blades spinning
  • Persistent clogs or slow drainage
  • Water leaking under the sink
  • A foul smell that won’t go away
  • Unusual grinding noises or vibrations
  • The system shuts off mid-use

Our San Marcos plumbers can quickly diagnose the issue and recommend whether a repair or full replacement is the most ideal solution. We make decisions based on the age and condition of your unit, ensuring smooth operation in no time.

When Should I Replace My Garbage Disposal?

Even the best garbage disposals don’t last forever. Below are signs that it might be time to consider a replacement.

Food Takes Longer To Grind

If your disposal is taking longer to break down basic food waste — or leaves larger particles behind — the blades may be worn or the motor could be failing. Our team can assess the unit’s performance to determine if it’s outdated and needs to be replaced.

System Requires Frequent Resets

Having to hit the reset button more than once in a while is a sign the disposal is struggling to keep up with its normal routine. This problem may be due to internal wear or electrical issues.

Disposal Is Older Than 10 Years

Most garbage disposals have a lifespan of 8–12 years. If yours is approaching that window and showing signs of decline, a replacement from our team can save you from frequent breakdowns and plumbing repairs.

Persistent Leaks From The System

Water leaking from the disposal — especially around the base or seals — often indicates damage that’s not worth repairing. A new unit offers a clean, efficient fix. We’ll inspect the system to determine the source of the water loss and perform the corrective pipe leak repairs or system upgrades.
