Understanding the Garbage Disposal
A garbage disposal is an essential kitchen appliance, invented in 1927 by John Hammes. It’s designed to collect solid food waste in a grinding chamber mounted under the sink. When activated, a spinning disc forces the food waste against the grinding chamber walls, breaking it into tiny particles. These particles are then washed through holes in the chamber wall with water. Despite common misconceptions, garbage disposals do not have sharp blades but use impellers to grind food waste.
The Anatomy of a Garbage Disposal Unit
A typical garbage disposal unit comprises several key components:
- Mounting Assembly: Attaches the unit to the kitchen sink.
- Grinding Chamber: Collects and pulverizes food waste.
- Impellers: Force food against the grinding chamber walls.
- Drain Hole: Allows pulverized food to be washed away.
- Motor: Powers the impellers to grind food waste.
Understanding these parts can help in garbage disposal troubleshooting and maintenance.
Things to Avoid Putting in Your Garbage Disposal
Garbage disposals are not the same as garbage cans. To prevent clogs and jams, avoid putting the following items in your disposal:
Tough or Fibrous Food Scraps
Examples include banana peels, celery, and other fibrous vegetables. These items can wrap around the impellers and cause jams.
Potato Peels
These can form a starchy paste that can clog your drain. It’s best to dispose of them in the trash.
Grease and Oil
These substances can solidify and cause blockages in the drain lines. Always let grease cool and solidify before disposing of it in the trash.
Coffee Grounds
Although they may seem harmless, coffee grounds can accumulate and form sludge in the pipes, leading to clogs.
Pits and Other Hard Objects
Hard objects such as bones, fruit pits, and shells can damage the grinding mechanism and cause jams.
Common Garbage Disposal Problems and Troubleshooting
Clogged Garbage Disposal
Clogs often occur when improper food items like grease, potato peels, or hard-to-grind foods are put down the disposal. Most clogs happen in the drainpipe downstream of the disposal. To clear a clog:
- Disconnect the Power: Always disconnect the power to prevent accidents.
- Use a Mixture of Baking Soda and Vinegar: This can help break down minor clogs. Follow with hot water to flush the pipes.
- Manual Removal: If necessary, manually remove the clog using an allen wrench to rotate the blades and dislodge the blockage.
Disposal Won’t Turn On
If your garbage disposal won’t turn on, it might be due to a tripped circuit breaker or a blown fuse. Here’s how to troubleshoot:
- Check the Circuit Breaker: Reset it if necessary.
- Press the Reset Button: Most units have a reset button located on the bottom.
- Inspect the Wiring: Ensure all connections are secure. If it still doesn’t work, it might need professional repair.
Humming Sound
A humming sound often indicates a jam. To fix it:
- Disconnect the Power: Safety first.
- Use an Allen Wrench: Insert it into the bottom of the disposal unit and manually rotate the blades to dislodge the jam.
- Check for Foreign Objects: Look inside the disposal and remove any visible obstructions.
Garbage Disposal Installation and Removal
Installing a Garbage Disposal
Installing a garbage disposal requires basic plumbing and electrical skills. Here’s a simple guide:
- Turn Off the Power: Ensure safety by disconnecting the power.
- Remove Existing Drain Pipes: Disconnect the drain lines and remove any old mounting assembly.
- Mount the Disposal Unit: Attach the new unit to the sink flange.
- Connect Electrical Wiring: Securely connect the wiring and attach the drain pipes.
- Run Cold Water and Test the Unit: Ensure everything is connected properly and test for leaks.
Removing a Garbage Disposal
Sometimes, garbage disposal removal is necessary for repairs or replacement. Here’s how to do it:
- Disconnect the Power: Always ensure the unit is not connected to power.
- Unscrew the Mounting Assembly: Detach the disposal from the sink flange.
- Disconnect Drain Pipes and Electrical Wiring: Carefully disconnect all connections.
- Remove the Disposal Unit: Lift it out from under the sink.
Preventing Clogs and Maintenance Tips
Proper maintenance can extend the life of your garbage disposal and prevent clogs. Here are some tips:
Use Cold Water
Always run cold water while using the disposal to solidify any grease or oils, allowing them to be ground up and flushed away.
Regular Cleaning
Clean your garbage disposal every two weeks using a mixture of baking soda and vinegar. This helps to eliminate odors and maintain efficiency.
Avoid Hard and Fibrous Food Items
Avoid grinding hard food items like bones and fibrous items like banana peels. These can cause damage and lead to clogs.
Use it Regularly
Frequent use prevents rust and corrosion, ensuring the disposal runs smoothly.
Flush with Hot Water
After each use, flush the disposal with hot water to clear any remaining food particles.
Selecting a New Garbage Disposal
When choosing a new garbage disposal, consider factors such as:
Grinding Power
Higher horsepower units handle more types of food scraps efficiently, reducing the likelihood of clogs and jams.
Noise Level
Look for models with noise-reducing features. Modern disposals often include insulation to minimize noise during operation.
Durability
Stainless steel components are more durable and less prone to rust and corrosion, increasing the longevity of the unit.
Size and Compatibility
Ensure the unit fits under your sink and matches your plumbing setup. Measure the space and check the specifications of the disposal before purchasing.
Extra Features
Some disposals come with additional features such as auto-reverse mode to clear jams, or anti-splash baffles to keep water contained.
