Disposal Jammed or Leaking
Turn off the wall switch and, if you can reach it, the breaker. Never put your hand or a tool into the disposal while it has power. A humming sound with no grinding means the blades are stuck, and you can often free them with the hex-key socket underneath, but only with the power off.
A leak from the base or the sink flange is a seal or housing failure. Place a bucket under it, wipe up water to protect the cabinet and call. A leaking disposal often needs replacement, since a cracked housing cannot be repaired.
Disposal Symptoms and Causes
| Symptom | Likely cause | What a plumber does |
|---|---|---|
| Hums but does not spin | Jammed flywheel | Frees the jam and checks the motor |
| Silent, no hum | Tripped reset or breaker, or a dead motor | Tests power and replaces the unit if needed |
| Leaks from the bottom | Cracked housing or failed seal | Replace the unit |
| Leaks from the top | Failed sink flange seal | Reseat the flange with new putty or gasket |
| Sink drains slowly or backs up | Clogged trap or drain line | Clear the line, see drain cleaning |
| Bad smell | Residue in the grinding chamber or trap | Clean the unit and the trap |
Why Disposals Fail
The most common causes are hard or stringy items, too much food at once, grease that coats the drain downstream and age. Fibrous scraps such as celery and corn husks tangle, and bones and pits can jam the flywheel. Grease cools in the pipe beyond the disposal and builds up until the drain clogs.
When the disposal is working but the sink backs up, the problem is usually in the drain line and not the machine. A cable or a jetter can clear that, and the plumber checks both parts before recommending a repair.
Disposal Not Working?
Call the 24/7 line. Same-day appointments are offered when available, and you hear the price first.
Repair or Replace
A jam and a tripped reset are repair-level problems. A leaking housing or a dead motor means replacement. If your unit is old and was working poorly even before it failed, replacement often makes more sense than a repair that buys a few more months.
Ask about horsepower and features when you replace it. A larger motor and sound insulation make a difference in a household that uses the disposal heavily, and the plumber can match the unit to your sink and mounting.
Installing a New Disposal
- 1
Remove the old unit
The plumber disconnects the drain, dishwasher hose and power, then removes the mounting assembly.
- 2
Mount the new unit
A new sink flange seal and mount hold the disposal securely.
- 3
Connect the plumbing
The drain and dishwasher connection are attached, with fresh gaskets.
- 4
Wire and test
Power is connected, the unit is run with water and the connections are checked for leaks.
Keeping a Disposal Healthy
- Run plenty of cold water while grinding and for several seconds afterward
- Feed scraps in gradually, not all at once
- Keep grease, coffee grounds in volume, bones, pits and fibrous peels out of it
- Do not use chemical drain cleaners in a sink with a disposal
- Never put a hand into the disposal, and use tongs for anything stuck
Kitchens in Rolling Meadows Homes
Kitchens in older Rolling Meadows houses often have a compact sink base cabinet, which limits the size of disposal that fits. The plumber measures the cabinet and the sink opening before recommending a model. If you are remodeling the kitchen, the disposal is best chosen along with the sink, and the faucet and sink repair page covers related fixtures.
What Affects the Price
Disposal work is priced by what is wrong and what you choose.
Insurance may cover water damage from a sudden leak but not the disposal itself. Want your real number? Call (847) 281-8626.
