How Does A Garbage Disposal Work?
A garbage disposal is a kitchen appliance designed to shred and dispose of food waste through the plumbing system, ultimately preventing it from ending up in landfills. Here’s how a garbage disposal works:
- Installation: A garbage disposal unit is typically installed under the kitchen sink, attached to the drain. It consists of a motor, a grinding chamber, and a set of rotating blades.
- Switching On To activate the garbage disposal, you turn on a switch located on the wall or the unit itself. This switch sends an electrical signal to the motor.
- Grinding Process: Once activated, the motor turns the set of rotating blades inside the grinding chamber. The blades are designed to spin rapidly, creating a powerful vortex.
- Food Waste Addition: You can feed small pieces of food waste into the sink’s drain. As the food waste enters the disposal unit, the spinning blades forcefully chop and grind it into tiny particles.
- Water Flow: During the grinding process, water is usually run into the sink to help carry the ground-up food waste through the plumbing system. The water also helps cool down the motor and flush away the particles.
- Particle Size: The blades are efficient at breaking down food waste into very small particles, usually less than 2 mm in diameter. This particle size is small enough to easily pass through plumbing pipes without causing blockages.
- Drainage: The ground-up food waste, mixed with water, flows through the plumbing system and into the sewer or septic system of your property.
- Cleaning And Deodorizing: Some garbage disposals have features like an anti-jam mechanism and self-cleaning technology to keep the unit functioning smoothly and reduce unpleasant odors.
- Maintenance: Regular use of the garbage disposal helps prevent the buildup of food waste in the pipes, reducing the risk of clogs. Running cold water while the disposal is in use helps solidify grease and oil, making it easier for them to be ground and washed away.
- Limitations: Not all types of food waste can be processed by a garbage disposal. Items like bones, hard shells, fruit pits, and fibrous materials like corn husks can damage the unit or cause clogs. It’s important to refer to the manufacturer’s guidelines for proper usage.
Pros Of Using A Dedicated Circuit For A Garbage Disposal
