A garbage disposal takes a beating and eventually jams, leaks, or burns out its motor. Most jams are a simple fix; a leak from the base or a dead motor usually means replacement. We diagnose which one you have rather than automatically reaching for a new unit.
When replacement makes sense, we size the horsepower to how the kitchen actually gets used and make sure the new unit is mounted, sealed, and wired correctly so it does not leak or vibrate loose.
Jammed versus dead
A disposal that hums but will not spin is almost always jammed, and clearing it with the reset button and the hex-key wrench port is usually all it needs. A disposal that is silent even with power confirmed at the outlet has likely burned out its motor or tripped internally beyond a simple reset.
A leak from the bottom of the unit, rather than the plumbing connections, means the housing has failed internally and the disposal needs replacing rather than repairing.
Installing a new unit correctly
We check the sink flange seal, dishwasher connection, and electrical hookup, since a disposal installed with a rushed seal is a slow leak waiting to happen under your sink. Sizing the horsepower to your household's actual cooking habits avoids both an underpowered unit that jams constantly and paying for more disposal than you need.
If your kitchen is on well or septic on the county fringe near Peoria, we will also talk through how disposal use interacts with a septic system, since heavy disposal use is one of the more common things that overloads a tank.
We stock common mounting and connection hardware on the truck for most standard sink configurations, so a straightforward replacement rarely needs a second visit just to source a part.
Quick disposal troubleshooting
- Humming, not spinning: try the reset button, then the hex key from underneath
- Nothing at all: check the outlet and breaker before assuming it is dead
- Leaking from the bottom: shut it off, that is a replacement, not a repair
- Persistent jamming: often something rigid like a bone or fruit pit lodged inside
Disposal safety: what not to do
Never put your hand in a disposal, even one that appears off.
- Always disconnect power before clearing a jam by hand
- Use the hex key or a tool, never fingers, to free the impeller
- Keep bones, fibrous produce, and grease out of any disposal
- If it trips repeatedly, stop using it and call rather than keep resetting
Frequently asked questions
My disposal hums but does not spin. Is it dead?
Probably not. That is the classic sign of a jam, and the reset button plus the hex-key port under the unit clears most of them. A truly dead motor is silent even when power is confirmed.
Is it worth repairing an old disposal?
If it is jammed or the seal needs replacing, often yes. If the motor has burned out or it is leaking from the housing, replacement is more sensible and gives you a fresh warranty.
What size disposal do I need?
It depends on how the kitchen is actually used. A lighter household does fine with a standard unit; a kitchen that processes a lot of scraps benefits from more horsepower. We will size it to your habits, not oversell you.
Can a garbage disposal hurt my septic system?
It can overload a tank faster if it is used heavily, since it adds solid waste to what the system has to break down. If you are on septic near Peoria's fringe, we will talk through reasonable use with you.
