An Alpharetta disposal that hums, stays silent or drips usually has a jam, a tripped reset, a worn seal or a tired motor. A few safe checks can sort out the simple cases; for the rest, a plumber can repair or replace the unit. Call the number on this page to be connected with a local plumber in Alpharetta.

Alpharetta kitchens
Alpharetta is an established north Fulton suburb and tech hub whose housing is mostly 1980s through 2000s subdivisions. About 57% of homes were built between 1980 and 1999, with a median build year of 1996 according to Census survey figures, and under 8% predate 1980. Many kitchens are on their second or third disposal, and the units put in during the last remodel are now wearing out. The drains are usually modern, so the fix is more often the unit than the pipe. The city doesn't run water or sewer; Fulton County Public Works provides both, with a North Fulton sewer line at 404-612-3061 for problems in the public main. Trade permits go through the city's online permit portal, so ask your plumber whether your job needs one.
What to do right now
- Kill the power first. Flip the switch off and pull the plug under the sink before touching anything.
- Look, don't grab. A flashlight shows what's in the chamber; tongs remove it safely.
- 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.
- Pause the dishwasher. If it drains through the disposal, its water has nowhere to go.
- Look for water. Put a towel down and note where the moisture collects.
- Check who to call. Fulton County Public Works handles the public sewer; the house side is yours.
- Call if it won't recover. A unit that stays silent, keeps humming or leaks from the bottom needs a plumber.
Symptoms and likely causes
| Symptom | Likely cause |
|---|---|
| Drip at the top | Loose mount or dried-out plumber's putty at the sink flange |
| No sound at all | Tripped reset, breaker, switch or failed motor |
| Trips the breaker | Motor strain from a jam, or a failing motor |
| Dishwasher water in the sink | Clogged disposal inlet or trap, or a knockout plug left in |
| Hums, won't turn | Something wedged between the plate and the grinding ring |
| Water from the bottom | Internal seal failure; the unit usually needs replacing |
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.
