Repair or Replace a Garbage Disposal? A Vacaville Guide

Many disposals that seem dead are fine once the real problem is found. These are usually repairs, not replacements:

1. 1It hums but doesn't turn. Something is jammed between the turntable and the grinding ring. With the power off at the switch, it can often be freed with the hex key that fits the socket on the bottom of the unit.
2. 2It is completely silent. The overload reset button on the bottom has tripped, or the breaker or wall switch has failed.
3. 3The sink drains slowly even though the disposal runs. The clog is usually in the trap or drain line below the disposal, not in the unit.
4. 4It leaks at the top, where it meets the sink. The sink flange seal or mounting ring has loosened. This can be reset and resealed.
5. 5It leaks at the side connection. The dishwasher hose or the drain elbow gasket is loose or worn, which is a parts fix.

Our guide on what to check when a garbage disposal is not working walks through the safe checks you can do yourself first.

Some failures are inside the sealed housing, and there is no practical repair:

1. 1Water leaks from the bottom of the unit. Internal seals have failed or the housing has cracked. Once water reaches the motor, replacement is the fix.
2. 2The motor is burnt out. It stays silent after a reset with power confirmed, or it smells of hot wiring.
3. 3Loud metallic grinding that continues after any jam is cleared, which often means broken internal parts.
4. 4It needs resetting or unjamming over and over, even with careful use. That is usually a motor on its way out.
5. 5It is too small for how you cook. A light-duty unit in a busy kitchen jams and clogs far more than a heavier one.

If more than one of these applies, a new unit is usually better value than repeated service calls.

We can't quote a price without seeing the setup, but the main things that change the total are:

1. 1Horsepower and build quality. A standard 1/3 or 1/2 horsepower unit for light use costs less than a heavy-duty 3/4 or 1 horsepower model built for frequent cooking and tougher scraps.
2. 2Like-for-like or not. Swapping a unit for one with the same mount is quicker than changing brands, which usually means a new mounting ring and sink flange.
3. 3The plumbing under the sink. Corroded traps, a worn drain line or an old dishwasher hose may need replacing at the same time.
4. 4The electrical connection. Most installs reuse the existing hardwired connection or outlet. If there is no safe power supply under the sink, that changes the job.

C&C Plumbing gives free estimates and upfront pricing, so you know the total for the unit and the labor before we start. Financing is also available.

Most garbage disposal installations take about an hour when the under-sink plumbing and electrical connections are in good condition. A typical visit:

1. 1Diagnose first, to confirm a repair isn't enough.
2. 2Disconnect the power and remove the old unit and its mount.
3. 3Install the new mounting ring and sink flange, sealed to the sink.
4. 4Hang the new disposal and reconnect the drain line and the dishwasher discharge hose.
5. 5Run water and test the unit, checking every connection for leaks and making sure it runs smoothly.

Same-day service is available for garbage disposal problems, because a broken kitchen sink disrupts the whole house.

A disposal handles soft food scraps. Most early failures come from what goes into it:

1. 1Keep cooking grease out. Fats, oils and grease harden in the pipes. The U.S. Environmental Protection Agency lists them among the materials that create sewer blockages, and they cause clogs in your own drain line long before they reach the city's sewer. Wipe greasy pans and put the grease in the trash.
2. 2Skip fibrous and starchy scraps in quantity: celery, onion skins, corn husks, potato peels, rice and pasta.
3. 3Never use it for bones, fruit pits or coffee grounds in bulk.
4. 4Run cold water while it runs and for a few seconds after.
5. 5Use it often. A disposal that sits unused for weeks is more likely to rust and seize.

If drains keep backing up even with a working disposal, the problem may be further down the line. Our drain cleaning services can clear and camera-inspect it.
