A Sugar Hill disposal that hums, won't start or leaks usually has a jam, a tripped reset, a failed seal or a worn motor. Some homes here aren't on municipal sewer, which changes how a disposal should be used. Call the number on this page to be connected with a local plumber in Sugar Hill.
Sugar Hill's setup
Sugar Hill is a fast-growing north Gwinnett city near Lake Lanier. It mails as Buford, but its water and sewer come from Gwinnett County Department of Water Resources, not the City of Buford; the city has no water or sewer department. The city's FAQ sends water and sewer emergencies to Gwinnett DWR at 678.376.7000, and notes that some properties are not on municipal sewer and use private onsite wastewater systems, which are the owner's responsibility. If your home is one of them, ground food adds solids to the tank, so use a disposal lightly. Permits go through Sugar Hill's Building Services at 5039 West Broad Street (770-945-6734); ask your plumber whether a disposal job needs one.
What to do right now
- Switch it off and unplug it. If it's hardwired, shut the breaker that feeds it.
- Don't reach inside. Fish out visible objects with pliers or tongs only.
- Free the plate from below. The wrench that came with the unit fits the center socket underneath; rock it back and forth.
- Reset the overload. Press the button on the underside, then test with cold water flowing.
- Skip the chemicals. Drain openers rarely clear a disposal clog and can damage its seals.
- Trace any leak. A paper towel wiped around the flange, hose and housing shows where water is getting out.
- Confirm your hookup. If your home is on a private onsite system rather than Gwinnett sewer, mention it.
- Stop if it hums again. Repeated humming can burn out the motor; leave it off and call.
Symptoms and likely causes
| Symptom | Likely cause |
|---|---|
| Dead switch, no hum | Overload tripped, loose plug or worn-out motor |
| Drip at the top | Loose mount or dried-out plumber's putty at the sink flange |
| Persistent odor | Food film under the splash guard or a drain holding water |
| Water from the bottom | Internal seal failure; the unit usually needs replacing |
| Sink drains slowly | Packed trap or a narrowed kitchen branch line |
| Hums, won't turn | Something wedged between the plate and the grinding ring |
What affects the cost
- What's wrong: a reset or freed jam takes less time than a replacement.
- The new unit: motor size, grinding stages and insulation set its price.
- Fittings: worn hoses, traps or mounting rings add parts.
- Power: hardwired units take longer than plug-in models.
- The drain: clearing a packed line is separate work.
