A leak under the kitchen sink right now
A garbage disposal is a grinder bolted to the bottom of the sink drain, with a motor, a grind chamber, a mounting ring, and a drain outlet that connects to the trap. Leaks come from three places: the sink flange at the top, the body seams, or the drain outlet and dishwasher hose.
Water in the cabinet can swell the base panel within a day, so treat a steady leak as urgent.
- 1Switch the disposal off and unplug it under the sink, or flip its breaker if it is hardwired
- 2Close the two shutoffs under the sink if the faucet is involved, then stop using the sink
- 3Empty the cabinet and set a bowl under the drip, noting where it comes from
- 4Call (855) 575-2890 and say whether it drips from the top, the side or the pipe on the right
What to do before we arrive
- ✓Cut the power first. Switch the disposal off at the wall switch, then unplug it under the sink or turn off its breaker.
- ✓Keep hands out of the chamber. Never reach into a disposal. Use tongs or pliers for anything you can see, and only with the power off.
- ✓Stop running water into it. A leaking or jammed unit will overflow the sink or drip below. Set a bucket under the trap and empty the cabinet.
- ✓Note what you heard. Humming, silence or a grinding sound each point to a different fault, and the description speeds up the repair.
A humming or silent disposal, step by step
A jam is the most common fault, and usually the safest to clear. Power stays off the whole time.
- 01
Cut power
Turn off the wall switch, then unplug the unit or throw its breaker.
- 02
Rotate the flywheel
Insert a hex key in the bottom socket and work it back and forth until the plates move freely.
- 03
Remove the obstruction
Use tongs or pliers from above. Common culprits are olive pits, bottle caps, utensils and fruit stones.
- 04
Press reset
The red button on the bottom pops when the motor overheats. Wait a few minutes, then press it.
- 05
Test with water
Restore power, run cold water and flip the switch. If it only hums, stop and call.
If the unit does not respond after a reset, the motor or its wiring is likely worn, and repair at that point rarely makes economic sense.
Fix it or swap in a new one
A good rule: leaks from the unit body and dead motors lead to replacement, while jams and loose connections lead to repair.
Repairable
The unit itself is sound.
- Jammed flywheel
- Leaking sink flange (new putty and mounting ring)
- Loose drain outlet or dishwasher hose
- Tripped reset
Replace
Not worth sinking money into.
- Seam or body leak (casing corroded)
- Motor that hums but never turns after a clear jam
- Rusted grind chamber
- A unit that trips the breaker repeatedly
A replacement unit is usually a sized swap on the existing mount. The longer it has been in service, the more likely replacement is the honest answer.
What the symptom usually points to
| What you see | Likely cause | Safe first step |
|---|---|---|
| Humming, no grinding | Jammed flywheel | Power off, hex key from below, remove object |
| Total silence | Tripped reset, breaker or dead motor | Press reset, check breaker |
| Water at the top rim | Failed sink flange seal | Stop using sink, call |
| Water from the side | Cracked casing or loose seam | Replace the unit |
| Sink fills with gray water | Blocked trap or drain line | Stop running water, see below |
| Bad smell | Food buildup in the baffle and chamber | Ice and citrus peel, then a cleaning |
When the problem is the drain, not the disposal
A kitchen sink drains into a line that also carries grease, coffee grounds and starchy foods like rice and pasta. A disposal grinds them fine, but fine is not the same as gone, and they settle in the trap and the first stretch of drain pipe.
When both sink bowls fill together or the water rises while the dishwasher drains, the blockage is past the disposal. A professional drain cleaning clears it, and for a repeat clog a camera shows how far the build-up runs.
Removing and reinstalling a disposal
Customers often ask for a reinstall after a cabinet repair, a new sink or a countertop swap. The unit is unmounted by turning its ring, the drain is disconnected, and the dishwasher hose is freed.
On reinstall we replace the plumber's putty or gasket under the sink flange, knock out the dishwasher plug if a hose is being added, and reconnect to the trap. Wiring is either a plug or a hardwired connection, and electrical work belongs to a licensed electrician.
What changes the price of a disposal job
Repair or replacement
A flange reseal is a lighter job than a new unit.
Horsepower and build
Larger motors and stainless chambers cost more than basic models.
Mounting system
Some brands require a matching mount or a new bracket.
Electrical setup
A missing outlet or switch adds electrical work.
Trap and drain condition
Corroded pipes or an old trap often get replaced at the same time.
Insurance note. Homeowner insurance may cover water damage from a sudden leak but usually not the disposal itself, so check your policy. You see the price before work starts, with repair and replacement priced side by side where both make sense.
Kitchen waste and the Voorhees sewer
Voorhees collects sewage locally and conveys it to the Camden County Municipal Utilities Authority, according to the authority, so what goes down your kitchen drain reaches a shared public system. Grease and fibrous scraps harden in lines and are a common reason for blockages.
Homes in Gibbsboro and Somerdale face the same issue. Scrape plates, wipe pans with paper towels and run cold water for a few seconds before and after grinding.
Source type: Camden County Municipal Utilities AuthorityKeeping a disposal running
- ✓Run cold water while grinding and for 15 seconds after
- ✓Skip grease, bones, fibrous peels, coffee grounds and pasta
- ✓Grind ice and citrus peel occasionally to freshen the chamber
- ✓Check under the sink every few months for dampness or rust
- ✓Replace the unit before it starts leaking if it is old and noisy

Common questions
Yes. The 24/7 line is open for leaks and backups, and we offer same-day visits when schedules allow. Switch off the disposal and the sink supply while you wait.
Yes, with the power off. Use a hex key from below or tongs from above, never your hand, and press the red reset only when the motor is clear.
Food collects under the splash guard and on the chamber walls. Scrub the guard, run ice and citrus, and clear the trap. Persistent smell can mean a slow drain.
Yes. The disposal has a knockout plug on the dishwasher inlet that is removed on installation. If it is left in, the dishwasher cannot drain.
The trap or the line past it is probably partially blocked with grease and starch. That is a drain issue, not a motor issue.
Somewhat. At the utility-reported hardness of 88 mg/L, scale can form on the unit's inner parts and on faucet aerators. It rarely causes failure alone, but regular flushing helps.
