Garbage Disposals

Eliminate household food waste with a garbage disposal, including egg shells, potato peels and fruit rinds

Garbage Disposals - Garbage Disposals

An easy way to reduce the amount of food waste in your home is to install a garbage disposal. Quickly and efficiently eliminating leftover potato peels, fruit rinds and many other types of food waste, the disposal grinds it all into fine particles that are flushed out of the chamber and into the plumbing discharge pipes.

When disposers are used in conjunction with a septic system, it is recommended that housholds refrain from placing any solid, mineralized items such as egg or seafood shells into the disposer as it could contribute to the accumulation of sludge that may compromise the effectiveness of the septic system. More typical food waste items, such as food scraps and fruit and vegetable peels, are compatible with septic systems.

This buying guide highlights the different types of disposals available, including continuous feed and batch feed models and motor sizes.

Batch Feed Disposals

Batch feed models operate only when the disposal lid is engaged and the unit is activated

  • Offer reassurance of a covered operation.
  • Requires the use of a stopper prior to activation and thus are well suited for households with children.
  • Slightly more expensive than continuous feed models, but requires a little more set up time.
  • Feature advanced grinding and quieter operation.

Continuous Feed Disposals

Continuous feed models operate with the flick of a switch and run until switched off

  • Sink baffle, the rubber shield placed inside the sink opening, catches food debris within the disposal and funnels them to the disposal blades.
  • Some models offer auto-reverse functions, advanced grinding features and special circuitry to help eliminate jams.

Motor Sizes

Basic models offer 1/3 horsepower while advanced models offer up to 1 HP

  • Small households with infrequent meal preparation only need a basic model.
  • Households with 2 or more people should consider disposals with ½, ¾ or 1 HP.
  • Higher horsepower is recommended for those who want a model to handle difficult to grind food waste, such as fibrous materials or bones.
  • Higher horsepower models offer better sound insulation and usually run quieter than basic models.

Operational Tips

Always disconnect the power before reaching into the disposal to avoid injury

  • Never stick your hand into an operating disposal.
