Stop a small problem becoming a sink backup
Garbage disposals fail in several common ways — some inside the unit, others from the sink drain, dishwasher connection, trap, or plumbing under the cabinet. A small disposal problem can quickly turn into a kitchen sink backup.
Some problems can be repaired; others are better solved with a new unit. We help you understand the difference before the work moves forward. Call (386) 353-9386.
Garbage disposal problems we fix
Some issues start inside the unit; others come from the drain, trap, or connections.
Won’t turn on
A tripped reset, power issue, failed switch, wiring concern, or failed motor. Don’t keep flipping the switch if it isn’t responding — call for help.
Hums but won’t grind
The motor has power but the grinding plate is stuck. Turn it off right away — running it while it hums can burn out the motor. Never reach inside.
Jammed
Food scraps, fibrous material, utensils, small objects, or buildup stop it spinning. We clear jams safely and check it still works afterward.
Leaks under the sink
From the body, sink flange, mounting, drain pipe, or dishwasher connection. A loose connection may be repairable; a cracked body usually means replacement.
Slow sink drain
The disposal and drain work together. Grease, food debris, soap, and starchy waste build up and slow the drain.
See Drain Cleaning →Bad odors
Food waste trapped in the disposal, splash guard, drain, or trap. If cleaning doesn’t help, the drain may have deeper buildup.
Loud grinding or rattling
A disposal shouldn’t sound like metal bouncing inside. A foreign object may be stuck or a part loose — turn it off and don’t reach in.
Keeps tripping or stopping
Working briefly then shutting off can mean overloaded, jammed, overheating, or failing internally. Repeated resets usually mean service or replacement.
Disposal repair vs replacement
The right choice depends on the problem, the unit’s age, the leak source, motor condition, and repair cost.
When repair makes sense
The unit is in good condition and the issue is isolated.
When replacement may be better
The disposal has a serious issue or keeps failing.
Garbage disposal installation
A new disposal needs proper setup to work correctly and avoid leaks.
New installation
If your kitchen has no disposal, installation may be possible depending on the sink, drain setup, cabinet space, and connection. It must connect properly to the sink drain.
Replacement
We remove the old unit and install a replacement when the setup fits — then check for leaks, drain flow, and proper operation.
Customer-provided unit
Already bought a disposal? We may be able to install it if it fits the sink and plumbing. Compatibility — space, drain, and connections — should be checked first.
Dishwasher connection
Many kitchens drain the dishwasher through the disposal. When the disposal is replaced, that connection must be handled correctly so both drain properly.
See Kitchen Plumbing →Safe steps before you call
A garbage disposal can be dangerous if handled the wrong way.
Turn the disposal off
Make sure the wall switch is off. If you’re checking under the sink, turn off power at the switch and breaker if needed.
Never reach inside
Never put your hand into a disposal, even with the switch off — sharp parts, trapped objects, and power risks.
Don’t run a humming unit
If it hums but doesn’t grind, turn it off. Keeping it on can burn out the motor.
Avoid chemical cleaners
They’re harsh and may sit in the disposal or drain if they don’t clear it, creating safety concerns for anyone working on the line later.
Stop using a backing-up sink
If water is backing up, stop running water — more water makes the backup worse.
