What disposal repair covers
A disposal grinds food with a spinning plate, and it fails when something jams the plate, a seal wears out or the motor gives up. A humming sound with no grinding means a jam, while a leak underneath means a seal or the flange has failed.
The plumber clears the jam with the hex key on the bottom of the unit, resets the overload button and replaces seals or the whole disposal when the motor is spent. Drain trouble beyond the disposal is a job for drain cleaning.
Disposal leaking or smoking: what to do first
Turn off the wall switch and, if you can reach it, unplug the unit or switch off its breaker before doing anything else. Never put a hand or a tool other than a wooden spoon handle into the chamber.
If water is leaking, shut off the supply valves under the sink and put a bucket under the unit. Smoke or a burning smell means leave the power off and call.
Signs your disposal needs help
Humming but no grinding
The plate is jammed, or the motor is stalled.
Water leaking beneath the unit
Seals have failed or the unit has cracked.
Water around the flange at the sink
The mounting ring is loose or the putty has failed.
The unit trips the breaker
The motor or wiring is shorted.
A bad smell that cleaning does not remove
Food is trapped in the chamber or the drain is partly blocked.
Water backs up into the second sink bowl
The drain line past the disposal is clogged.
What should and should not go down
| Safe in moderation | Avoid |
|---|---|
| Small soft food scraps with running cold water | Grease, oil and fat |
| Citrus peels in small amounts | Coffee grounds in quantity |
| Ice, only in small amounts | Bones, corn husks and fibrous stalks |
| Water running for 15 seconds after grinding | Pasta, rice and potato peels in large amounts |
Disposal won't run?
Call the 24/7 line. A plumber is dispatched with the earliest available slot.
Repair or replace
A jam is often a quick fix, and a worn seal can be replaced on some models. If the motor is burnt out or the housing has rusted through, a new disposal costs less than repeated service.
Installing a new unit means connecting the drain, the dishwasher inlet and the electrical supply. The plumber also checks the sink flange and trap, which pairs with faucet and sink repair.
What decides the price of a disposal repair
A jam is a short visit. A replacement is priced by the unit and the connections. You hear the price before work starts.
Run cold water before, during and for 15 seconds after grinding to move scraps through.
Grease, the city sewer and the kitchen drain
The City of Caldwell's pretreatment program asks residents and businesses to keep cooking oil and grease out of sinks, garbage disposals, toilets and floor drains. Grease that gets past the disposal cools in the drain and builds the coating that causes kitchen backups.
The same program warns against additives that claim to dissolve grease. Scraping pans into the trash is the habit that protects your disposal and the city sewer.
Homes in Middleton can book the same visits.
A new disposal ties into the drain, which makes it work under the UPC, the 2015 Uniform Plumbing Code that Idaho has adopted with state amendments.
