How a Garbage Disposal Works |
Posted: April 17, 2018 |
Purpose of a Disposal Unit A garbage disposal unit is installed on the underside of your kitchen sink. This unit functions to take unwanted, biodegradable food scraps such as apple peels or orange rinds, grind them and flush them down your drain. The food scraps are kept in the hopper, located below the drain until ready to be disposed of. Impellers Garbage disposal units are powered by electric motors. The metal impellers work with a shredder ring in grinding and pulverizing the food waste. As the impellers spin, they toss the waste towards the shredder ring. The impellers and shredder ring work in tandem to grind your food waste. Water Flush While the impellers and shredder ring work to pulverize your scraps, it is the water from your tap which washes it down the drain. Most professional plumbers state to stay away from running hot water, and only cold for this operation, as the cold water keeps the scraps nice and hard, and easier to wash down. To Sewers or Septic Tank The water rushes the waste into the waste line connector, then to the units discharge outlet. From there it hits the sewers or septic system. If you use a septic tank system, make certain you follow the rules set forth by your city, as well as the manufacturer of your garbage disposal. Continuous Feed and Batch Feed There are two types of garbage disposals: Continuous Feed and Batch Feed. The continuous feed is the type most often seen in homes, and is the least expensive of the two. With the continuous feed, you start the disposal and then feed in your food scraps. In batch feed disposals, you place the scraps in the disposal before you start it. They also pose less risk as they are covered while the grinding takes place.
