A garbage disposal that hums and will not turn, or leaks onto the cabinet floor, is a problem that gets worse quickly, because the sink above it cannot be used. Lodi Pro Plumbing repairs and replaces disposals 24/7 in Lodi, NJ. Turn the switch off and the breaker if you can, and never put your hand into the disposal, even when it is off.
Garbage disposal repair covers a jammed grinder plate, a tripped overload, a leak at a seal or a flange, a dead motor and a drain line that clogs behind the unit. A jam is usually free to clear. A leak from the housing is not repairable and means replacement.
Disposal jammed, leaking or dead? Call (973) 488-5410 and stay clear of the opening.
Call (973) 488-5410Jams and humming
A humming disposal that does not spin has a jammed grinder plate. Safe steps, with the power off:
- Turn the disposal off at the switch and unplug it, or switch the breaker off.
- Look for a hex-shaped hole on the bottom of the unit and insert the wrench that came with it, then work it back and forth.
- Use tongs or pliers, not fingers, to remove anything you can see in the chamber.
- Press the red reset button on the bottom of the unit.
- Restore power and run cold water, then try the switch.
If the disposal does not turn or the reset button pops out again, the motor or the wiring is likely at fault. Call the plumber, and do not keep pressing reset.
Leaks and what they mean
Where the water appears tells you what failed:
| Leak location | Cause | Fix |
|---|---|---|
| Top flange at the sink | Worn plumber's putty or mounting ring | Reseat the flange |
| Side where the drain pipe attaches | Loose or failed gasket | Tighten or replace the gasket |
| Bottom or housing seam | Corroded or cracked housing | Replace the disposal |
| Dishwasher inlet | Loose hose clamp | Tighten the clamp |
| Under the trap | Loose slip nut or failed trap | Tighten or replace the trap |
A leak from the bottom or the seam is not something a seal can fix. The housing has failed, and the unit should be replaced.
What disposals should and should not grind
Most repair calls trace back to what went down the drain:
- Grind small food scraps with cold water running.
- Avoid grease and oil, which coat the drain line behind the disposal.
- Keep bones, fruit pits, corn husks, celery strings and coffee grounds out in large amounts.
- Do not put in potato peels in bulk, rice or pasta, which swell and form paste.
- Run cold water for fifteen seconds after grinding.
Grease is the main reason kitchen drains back up. A disposal does not remove it, and the line behind it cools and holds it. See drain cleaning and hydro jetting for what happens when a kitchen line coats over.
Disposals in shared buildings
In buildings where units share a drain stack, a grease clog from one kitchen can back up into the units below. Lodi has 10,414 housing units on 2.29 square miles, and a lot of residents live close to neighbors. If the sink in the lowest unit backs up while upstairs units run water, the cause may be the stack and not the disposal, and the plumber will check it before replacing anything.
Landlords and managers can call us for both the unit and the stack, and we give the diagnosis in a form you can pass to the building owner.
Replacing a disposal
Replacement is usually straightforward when the sink has a standard flange. The plumber disconnects the old unit, mounts the new one, reconnects the drain and the dishwasher inlet and tests it. Points to settle before the visit:
- Horsepower: a half horsepower unit handles light use, three quarters or one horsepower handles heavier use.
- Mounting type: some models use a quick-lock mount that fits older flanges.
- Electrical: a disposal needs a switch and an outlet or hardwired connection, and the plumber checks that yours is safe.
- Dishwasher knockout: if a dishwasher connects to the disposal, the plug must be removed.
What decides the cost of disposal repair
- Repair or replace
- A jam is the lowest cost. A new disposal adds the price of the unit and installation.
- Unit size
- Higher horsepower units cost more.
- Electrical
- A missing outlet or switch adds work.
- Drain line
- A clog behind the unit adds cleaning time.
The plumber states the price before work starts and says whether a repair is worth it.
Garbage disposal questions
Do you repair garbage disposals at night or on weekends in Lodi?
Yes. The line is open 24/7. A leaking or dead disposal that blocks the sink is a same-day call, and the plumber gives a clear price before work starts.
Is it safe to use a hex wrench to clear a jam?
Yes, with the power off. Never use your hand. If the unit does not turn freely after you work the wrench, call us.
How long does a garbage disposal last?
It varies with use and with what goes in it. A unit that leaks from the housing is done, regardless of age.
Can you install a disposal where there is none?
Yes. The plumber checks the sink, the drain and the electrical supply first. See plumbing installation.
The sink is backed up. Is it the disposal?
Maybe. If the disposal runs and the sink still drains slowly, the line behind it is blocked, and cleaning the drain is the fix.
