Food Waste Disposer Repair or Replacement

It is easy to think of a food waste disposer as a convenience or luxury item in the modern kitchen, it is actually much more. It helps keep you kitchen clean, hygienic and is environmentally responsible.

Each year in the United States, nearly 34 million tons of food waste is trucked to landfills. Once there, it quickly decomposes and produces methane, an environmentally harmful greenhouse gas at least 21 times more potent than CO2.
While composting provides one approach to tackling America’s food waste management challenge, it isn’t always practical for today’s busy lifestyle.

Food waste disposers provide a convenient and environmentally friendly alternative to transporting leftovers to landfills. Plus, in areas that have capable wastewater treatment plants, some can even recycle food waste into energy and fertilizer.

Common Disposer Problems

Water does not go down or comes back up in the other compartment
This usually indicated that there is a stoppage in the sink drain. Sometimes this can be cleared by removing the p-trap and emptying its contents.

Disposer doesn’t turn on
If the disposal makes no noise when you turn it on, this is frequently an indication that the disposal was jammed and the current overload was tripped.

  • Locate and press the reset button (located on the bottom of most units), then check for a jam before turning on.
  • If still no noise, check breaker in electrical panel, reset, then check for a jam before turning on.

Disposer makes unusual noise
If it makes a buzzing or humming noise but doesn’t operate, turn the unit off. There may be a foreign object jamming the disposer that needs to be removed.

Caution: Before putting your hand or tools into the disposal, unplug it or turn off the breaker in the electrical panel.

Odor from Disposer
Over time, food particles, oils and grease may accumulate in the grind chamber and baffle. An odor from the disposer is usually a sign of these may have turned rancid. Use a disposer cleaner, degreaser, or deodorizer as necessary to relieve these objectionable odors. Sometimes grinding citrus may freshen up the drain smells.
