Humming, silent or leaking: what each one means
| Sign | Likely problem | Fix |
|---|---|---|
| Hums, will not spin | Jam in the grinding ring | Free the jam, reset the unit |
| Silent, no hum | Tripped reset or dead motor or switch | Reset, test power, then diagnose |
| Leak at the top flange | Failed sink seal | Reseat the flange with new putty |
| Leak from the side | Loose drain or dishwasher hose | Tighten or replace the hose |
| Leak from the bottom | Cracked housing or failed internal seal | Replace the unit |
A jam is common after something hard or fibrous lands in the chamber, such as a bone, fruit pit or too much stringy vegetable. The motor tries to turn and trips. There is a hex socket in the bottom of most units that lets us turn the plate by hand and release it, and a reset button on the base that restores power.
A leak at the bottom is different. Water in the housing corrodes the motor and shaft. That unit is done, and paying for a patch is not good value.
Clogged sink or slow drainage
A disposal that grinds but the sink drains slowly usually has a clog in the trap or the line beyond it. The unit only chops, it does not carry waste to the main. Grease and starch settle in the drain and build into a plug. If a sink backs up and the disposal is clean, the next step is drain cleaning.
What to do and not do
- Switch it off at the wall or breaker before checking anything.
- Run cold water while grinding and for 15 seconds after.
- Keep grease, coffee grounds, eggshells in bulk, pasta and rice out of the unit.
- Never use chemical drain cleaners in a sink with a disposal.
Replacing a disposal
A new unit makes sense when the housing leaks, the motor is dead, or the unit is old and noisy. Horsepower, feed type and sound insulation all affect price and performance. We can install a unit you bought, or supply one, connect the drain and dishwasher line, and wire it to the existing outlet. If new wiring or a new circuit is needed, that is electrical work, and we tell you plainly when an electrician is the right call.
What affects disposal repair cost
Repair or replace
A jam release is a short visit, a replacement includes the unit.
Unit size
Larger motors cost more.
Plumbing around it
A bad trap or dishwasher connection adds parts.
Electrical
Missing outlet or switch work is separate.
Access
A crowded sink base takes longer.
Insurance seldom covers worn appliances. For your real number, call (770) 214-4545.
Disposal jammed or leaking?
Call to book. Same-day visits are common when crews are available.
Tucker kitchens and disposals
Tucker's water comes from the DeKalb County system, which treats Chattahoochee River water at the Scott Candler plant. We do not quote a hardness figure because the county report does not give one for your tap, and a simple test kit will. Mineral buildup inside a disposal drain is something we look for when we replace the trap. We also repair the faucet above the sink, covered under faucet repair.
Standards and sources
Plumbing work in Georgia follows the state minimum plumbing code, which is built on the International Plumbing Code (IPC) with Georgia amendments. Ask the City of Tucker permit team which edition and which local rules apply to your address. Plumbers are licensed through the Secretary of State's Division of Master and Journeyman Plumbers, and you can ask for a license number. When you shop for toilets and faucets, the EPA WaterSense label marks models that meet its water efficiency criteria, and WaterSense toilets use 1.28 gallons per flush or less.

Questions we hear from homeowners
Humming means the motor is getting power but the grinding plate is stuck. A jam is the usual cause.
Often yes. Switch it off, wait a few minutes, then press the red reset button on the base. If it trips again, call us.
The source decides it. Leaks at the top or hoses are repairable. A leak from the bottom of the housing usually means replacement.
Yes. We connect the drain, the dishwasher line and the power to an existing outlet.
No. Chemicals can damage the unit and splash. A plumber can clear the line safely.
