Garbage Disposal Repair & Installation in Manassas, VA
A disposal that hums, jams or leaks is usually a quick fix, not a kitchen crisis. We clear jams, replace worn units, and wire and seal new ones so they do not leak into the cabinet.
When to call right away
- The disposal hums but will not spin
- Water leaking under the sink
- A persistent smell from the drain
- The unit is dead with no hum
Hum, jam, or dead tells you the fault
A garbage disposal gives away its problem by how it fails. A unit that hums but does not spin is jammed, with something wedged between the impeller and the housing. A unit that is completely dead, no hum at all, has usually tripped its internal reset or lost power. And one that spins freely but does not grind has a worn or broken impeller. Each is a different fix, and the humming jam in particular is one homeowners can sometimes clear, though forcing it is how a fixable jam becomes a burned-out motor.
Leaks are the other common call. A disposal can leak at the sink flange on top, at the dishwasher connection, or from the housing itself. The first two are seals that can be redone; a leak from the body of the unit means the housing has corroded through and the disposal is replaced. Water pooling in the cabinet from any of these tends to go unnoticed until it warps the cabinet floor.
Installing one that lasts
A clean disposal installation is mostly about the connections. A properly seated sink flange, a solid electrical connection, and the dishwarker drain tied in correctly are what keep a new unit from leaking or tripping. Matching the unit to how the kitchen is used matters too, since an underpowered disposal in a heavy-use kitchen jams constantly. The drain line it empties into needs to be clear as well, which is where a disposal problem and our drain cleaning sometimes overlap.
| Symptom | Cause | Fix |
|---|---|---|
| Hums, will not spin | Jam between impeller and housing | Clear the jam |
| Completely dead | Tripped reset or lost power | Reset, check the circuit |
| Leaking on top | Sink flange seal | Reseal the flange |
| Leaking from the body | Corroded housing | Replace the unit |
Because a disposal ties the kitchen sink to the drain, a chronic clog downstream can make even a healthy disposal seem to fail. Sorting out which one is the real problem is part of the visit, and a new faucet or sink often gets updated at the same time when a kitchen is being refreshed.

What a disposal can and cannot take
A lot of disposal failures are really habit problems, and a little knowledge prevents most of them. Fibrous scraps like celery and corn husks, starchy loads like potato peels and pasta, coffee grounds, and grease are the usual culprits, either wrapping the impeller or building up in the trap below. Running plenty of cold water while the unit works and for a few seconds after is the single best habit, because it carries waste through rather than letting it settle. None of this makes a disposal a trash can, and understanding its limits is what keeps a well-matched unit running for years rather than jamming every few weeks.
Questions
Garbage Disposal Repair & Installation: common questions
My disposal hums but will not turn. What now?
That is a jam, something wedged between the grinding plate and the housing. There is a hex socket on the bottom of most units that lets you free the impeller by hand, and a reset button that often needs pressing afterward. The important thing is not to keep running a jammed unit, because the humming is the motor straining, and forcing it burns the motor out. If it will not clear, we can free it without damage.
Why is my disposal leaking under the sink?
A disposal can leak from three places: the sink flange on top, the dishwasher hose connection, or the body of the unit itself. The top two are seals that can be redone. A leak coming from the housing itself means it has corroded through, and that unit needs replacing. Any of them can quietly pool water and warp the cabinet floor, so it is worth sorting promptly.
Can any disposal handle my kitchen?
Not equally. An underpowered unit in a heavy-use kitchen jams and struggles, while a well-matched one runs for years. Matching the horsepower and grind capacity to how the kitchen is actually used, plus a clear drain line for it to empty into, is what makes a disposal reliable rather than a recurring problem.
