Disposal leaking or jammed: first steps
Water under the sink, a burning smell or a disposal that will not stop humming is worth an urgent call, and our line answers 24/7. A few safe steps will limit the damage while you wait.
- Switch the disposal off at the wall switch and unplug it under the sink, or turn off its breaker.
- Never put a hand into the disposal, even when it is off. Use tongs or pliers to lift out anything visible.
- If water is leaking, close the two angle stops under the sink, clockwise, and put a bucket under the unit.
- Stop using the sink, and call (855) 575-2890 if the leak or the jam continues.
Garbage disposal repair in Los Gatos starts with a simple question, which is whether the problem is the motor, a jam, a leak or the drain behind it. A disposal grinds food into small pieces, but it relies on the sink trap and the two-inch drain line to carry them away. A disposal that sounds dead can turn out to be a clog downstream.
Disposal leaking into the cabinet or backing up the sink? Call (855) 575-2890 and switch the unit off at the wall first.
Call (855) 575-2890It hums but the blades do not turn
A steady hum with no spinning means the flywheel is jammed, usually by a bone, fruit pit or piece of silverware. Many units have a hex socket in the center of the bottom. A quarter-inch Allen key turned back and forth frees the flywheel.
After freeing it, press the red reset button on the bottom of the unit. If the motor trips again right away, the winding may be burned out and replacement is cheaper than repair.
Where is the water coming from?
Run water in the sink with a dry paper towel under the unit and watch which joint drips.
| Wet spot | Cause | Usual fix |
|---|---|---|
| Under the sink flange at the top | Dried plumber's putty or loose mounting ring | Reseat the flange with new putty |
| Side hose to the dishwasher | Loose clamp or cracked hose | New clamp or hose |
| Drain outlet to the trap | Worn gasket or loose elbow | New gasket, retighten |
| Seam or bottom of the unit | Rusted housing or failed seal | Replace the disposal |
| Only when the dishwasher runs | Clogged dishwasher drain port or air gap | Clear the port, clean the air gap |
A kitchen sink that backs up with the disposal running
A disposal pushes ground food into the drain, and grease in that food cools into a paste on the pipe wall. In many older kitchens the branch line is two inches wide and runs under the floor to the main. Coffee grounds, rice and pasta swell and settle in the trap.
If water rises in the other sink basin while the disposal runs, the clog is past the unit. A cable run through the trap or the cleanout clears it, and drain cleaning with a camera finds the cause when it keeps coming back. Repeat clogs can point to a belly in the line, which jetting cannot cure.
The dishwasher connection
Most disposals have a knockout plug on the side for the dishwasher drain hose. If it was never punched out during installation, the dishwasher will not drain. A kinked hose or a clogged air gap on the counter causes the opposite problem, with water spilling out of the air gap cap.
Both checks take a few minutes during a disposal visit, and a backed-up dishwasher is a common reason a sink smells.
Water, septic and the sewer district
West Valley Sanitation District, which serves Los Gatos, says to flush only toilet paper and human waste. The same sense applies at the sink. Grease, oil and stringy peels belong in the trash, and in the district's service area, restaurants must also use a grease control device, which shows how much the district cares about fats.
The Town of Los Gatos also has a permit checklist for abandoning septic tanks, so some properties may still have septic systems. If yours does, ask before adding a disposal, since extra solids load a tank faster. We also dispatch to the mountain communities above Los Gatos and the rest of the area.
Some Los Gatos properties, including hillside lots near Lexington Reservoir, may still be on septic rather than sewer, so say which you have when you call about a disposal. A septic tank changes what is safe to grind. This Santa Clara County dispatch covers ZIP codes 95030, 95031, 95032 and 95033.
Repair or replace the disposal?
A disposal is a modest machine, so age and the type of failure decide.
| Problem | Repair | Replace |
|---|---|---|
| Jam from an object | Free the flywheel, reset | No |
| Loose or leaking flange | Reseat with new putty | No |
| Leaking from the housing | No | Yes |
| Motor dead, resets do nothing | Rarely worth it | Yes |
| Rusted, loud and over a decade old | Short-term only | Yes, size to your use |
A larger horsepower motor grinds tougher scraps and runs quieter, but it needs the same sink opening.
Installing a new disposal
Replacement means disconnecting the dishwasher hose and drain elbow, releasing the mounting ring, and fitting the new unit to the sink flange. The electrical side is a plug or a hard-wire connection to a switched outlet. If the sink has no outlet, an electrician or a code-approved connection is needed, and permit rules vary, so check with the Town building division.
While the cabinet is open, we replace worn angle stops and braided lines, since those fail on the same schedule. A similar fix is covered under faucet repair.
What affects the price of a disposal repair
We explain what failed, then give a clear price before work starts.
Repair versus new unit
A reseated flange is quick. A new disposal adds the unit, installation and disposal of the old one.
Motor size
A heavier motor costs more and suits larger households.
Electrical access
A missing switched outlet adds work that may involve an electrician.
Downstream clog
A blocked branch line adds cable time.
Time of the call
Evening and weekend visits are priced differently from daytime appointments.
Insurance may cover a sudden flood from a failed hose, while wear and slow leaks under the sink often are not. Policies differ, so check yours.

Disposal questions from Los Gatos kitchens
Yes. Our dispatch line runs 24/7, and licensed plumbers go out for active leaks under the sink. We do not promise an arrival time, and the price is clear before work starts.
Yes, once it is switched off and unplugged. Use the Allen key socket and then the red reset button, and never reach in by hand.
The drain line past the unit is probably partly blocked, often with grease and settled food. A cable run clears it.
Yes. A loose hose clamp, a cracked dishwasher hose or a clogged drain port will do it.
It varies with use and with what goes down it. Rust at the seam or a dead motor means it is time for a replacement.
