Emergency Garbage Disposal Repair and Installation

A disposal that hums and will not turn, leaks into the cabinet or sends dishwasher water back up. Most jams clear with a hex key, and most leaks come from a seal or a connection. If the unit drips into the cabinet or pushes gray water into the dishwasher, switch it off at the wall and ring the dispatcher.

Switch the disposal off at the wall, never put a hand inside, and call if it leaks.

What the sound or the leak tells you

  • Humming but not spinningA jam. Turn it off and free the plate from underneath.
  • Dead, no soundA tripped reset button or breaker, or a failed motor.
  • Water in the cabinetA loose flange, a worn gasket or a cracked housing.

Clearing a jam

Turn the disposal off at the switch and unplug it or flip the breaker. Insert a hex key into the socket under the unit and work it back and forth to free the flywheel. Press the red reset button on the bottom.

Use tongs to remove anything stuck in the chamber. Never reach in by hand, even when the unit is off.

Leaks and where they come from

Leaks show up at three places. The flange at the sink seals with putty or a gasket, the discharge pipe connects with a rubber gasket and the dishwasher inlet has a hose clamp. A leak from the body itself means the housing has failed and the unit needs replacing.

Dry the cabinet and run water to see where the drip begins. A flashlight and a paper towel help.

Cost

What sets the bill for a disposal

Freeing a jam is quick and a swap takes little longer. These points change the total.

  • 1Horsepower and brand. Larger units cost more.
  • 2Wiring or cord. Hard-wired units need electrical care.
  • 3Dishwasher connection. A new inlet or air gap adds parts.
  • 4Drain condition. A downstream clog is a separate service.

Ask what warranty comes with the unit and with the labor.

In Westminster

Kitchens and the shared drain

A disposal that backs up often connects to a drain line that is partly clogged farther down. If water backs into the second sink or the dishwasher, the kitchen branch line needs cleaning.

Mineral scale from moderately hard water can build inside the grinding chamber and on the drain. A periodic flush with warm water helps.

Installing a new disposal

A replacement uses the same mounting ring on most sinks. The plumber disconnects the old unit, mounts the new one, connects the drain and the dishwasher line and wires or plugs it in.

Electrical work on a hard-wired unit should be done by a qualified person. Ask about a cord kit if the sink has an outlet under it.

Care that extends life

Run cold water while the unit runs, and for a short time afterward, to flush the line. Avoid grease, coffee grounds in bulk, fibrous vegetables and large bones.

The city asks residents to keep fats, oils and grease out of the sewer. A disposal does not change that, and grease that goes through it still hardens down the line.

Safe use

Habits that save the disposal

Small changes make it last longer.

  • 1Run cold water. It keeps grease firm and moving.
  • 2Feed in small amounts. Do not stuff the chamber.
  • 3Skip fibrous scraps. Celery, corn husks and potato peel can wrap around the blades.
  • 4Avoid grease. Pour it into a container and put it in the trash.
  • 5Clean with ice and citrus. It freshens the chamber without chemicals.

Common questions

Answers about disposal

The flywheel is jammed. Turn off power, use a hex key under the unit to free it and press the reset button.

A leak at the flange, gasket or hose can usually be repaired. A cracked housing needs a new unit.

The kitchen branch line is partly blocked. Disposals add food waste that can build up and clog.

No. Chemical cleaners can damage the seals and are unsafe to handle.

Cut power to it, clear the cabinet and call. Drips from the mounting flange, the gaskets or the drain hookup can usually be repaired, while a split casing means a new unit.

Disposal leaking or dead?

Turn it off at the switch and call. Say what it is doing and where it leaks.
