Garbage disposal units are electronic devices installed between the kitchen sink and the trap. They shred food waste into small pieces, allowing it to flow through plumbing and decompose easily. Widely used in the United States, they are now a mandatory feature in new homes across the country. John W.Hammes invented it in 1927. Initially, they were called InSinkErator; however, today, numerous variations of the best garbage disposal units exist under different brands, varying in sizes, shapes, designs, power, and price.
A garbage disposal unit generally connects to the plumbing of the sink, and when food goes into the drain, it collects in the chamber of the unit where a rotator blade cuts or grinds the food in tinier pieces. The compartment is lined with rubber casing to prevent noise while the food is grounded. It then passes through the pipe in the sink to the drain.
