Safe first steps

  • Turn off the disposal switch and unplug the unit or flip the breaker.
  • Never put a hand in the chamber. Use tongs or pliers.
  • Use the hex key slot at the bottom to turn the flywheel back and forth.
  • Push the small red reset button underneath the motor housing.
  • Run cold water and test only after clearing the jam.
  • Call if the unit leaks, smells burnt or trips the breaker again.

What not to put down a disposal

A disposal grinds soft food scraps. It does not make every item safe for the pipe. Grease, coffee grounds in large amounts, fibrous peels and starchy foods can clog the line.

  • Fats, oils and grease, which cool and harden in the drain.
  • Stringy produce like celery stalks and corn husks.
  • Pasta, rice and other starches that swell.
  • Bones, fruit pits and shells.
  • Non-food items such as utensils, paper and plastic.

If the kitchen line keeps backing up, the problem may be past the disposal. See drain cleaning.

Repair or replace

A jam or a tripped reset is a simple fix. A leak from the housing means replacement. If the unit is more than a decade old, replacement is often the sensible choice, since the parts cost nearly the same as a new one.

When you choose a new disposal, horsepower and noise level matter. Larger motors grind better and last longer. Ask for a unit with a sound-reducing housing if the kitchen is open to a living area.

How a replacement goes

  1. DisconnectPower is off, the drain and dishwasher lines are detached and the old unit is removed.
  2. Prep the flangeThe sink flange is cleaned and sealed with plumber's putty or a gasket.
  3. Mount the unitThe new disposal locks into the mounting ring.
  4. ReconnectDrain, dishwasher knockout and power are connected.
  5. TestRun water and check for leaks.

Installing a disposal where none exists means adding power and a switch. Ask whether an electrician is needed. Related sink work is on the faucet and sink repair page.

What changes the price

Pricing depends on the unit and whether electrical work is needed. Ask the dispatcher for a clear quote before work starts.
