Your disposal hums but won't spin โ the impeller plate is jammed. It's completely silent when you flip the switch โ the thermal overload protector has tripped or the motor has failed. Water drips from the sink collar โ the sink mounting gasket has deteriorated. Each of these is a different diagnosis, and each has a different solution. Masters Plumbing Service's techs in Perkins, MO arrive with the jamming tools, reset wrench, and replacement units to resolve any disposal failure same visit.

We carry replacement units on the truck in common horsepower ratings so a same-day swap is possible when the motor has genuinely failed.
Hum but no spin: jammed impeller. No sound at all: tripped thermal overload or failed motor. Intermittent operation: loose wiring at the switch or disposal unit. Continuous drain from the sink collar: failed sink flange gasket. Leak from the side: dishwasher drain hose connection or internal body crack. We trace the symptom to the specific cause before recommending any solution.
InSinkErator models use a 1/4-inch Allen wrench at the center bottom; Waste King models use a broom-handle approach at the top. Knowing which you have before arriving saves time and prevents the wrong tool damaging the motor shaft.
We give you the actual cost comparison. If clearing the jam and pressing the reset button fixes it, that's what we do. If the motor has failed, we show you the replacement options and install same-day.
A disposal isn't an isolated appliance โ it connects to the sink drain, the dishwasher drain (if present), and the drain arm leading to the p-trap. We inspect the full connection set during any disposal call: drain arm slope, dishwasher drain knockout (if a dishwasher is being added), and p-trap connection integrity.
Most disposal calls complete in 30โ60 minutes โ same visit, flat-rate pricing.
If the jam-clearing wrench won't budge the impeller, the motor shaft may be seized rather than just stuck from debris โ we distinguish between the two before recommending replacement.
A disposal that makes no sound when switched on has either tripped its thermal overload protector (the red button on the bottom โ press it and try again) or has a wiring issue at the switch or disposal unit. We check the reset button, test for power at the disposal's wire connection, and test the wall switch for continuity.
Disposal leaks come from three locations: the sink flange (top of the unit where it mounts to the sink drain opening โ repaired by re-sealing the flange with plumber's putty and re-tightening the mounting ring), the side port (dishwasher drain hose connection โ usually a loose hose clamp or cracked fitting), or the bottom of the unit (internal body crack or failed internal seal โ indicates replacement needed).
If the turntable bearing has failed โ indicated by a loud rumbling throughout operation rather than specific impact sounds โ that's an internal motor wear failure that warrants replacement.
A disposal that grinds normally but drains slowly has a blockage in the drain arm or p-trap โ not an internal disposal problem. Food particles and grease accumulate in the short drain arm between the disposal outlet and the p-trap. We disconnect and clean the drain arm, clear any p-trap buildup, and reinstall with clean connections.
When the motor has failed, the unit body is cracked, or the existing unit is underpowered for the household's use pattern, we replace the disposal with a new unit matched to the sink drain configuration. We carry 1/2 HP, 3/4 HP, and 1 HP units from InSinkErator and other major brands on our trucks for same-day installation.
No guesswork โ we diagnose before we quote, and quote before we start.
If you know the disposal is over 10 years old, tell us โ that changes how we approach the repair-vs-replace conversation upfront.
For leaks, we dry the area completely and run a short test cycle to confirm exactly which connection is dripping.
You decide. We don't upsell replacement when repair is the right answer, and we don't push a cheap repair that won't hold on a unit that's genuinely at end of life.
After repair or replacement, we run the disposal through a full test: several cycles with water running, check under the sink for any drip at all connection points, and confirm the drain arm clears at a normal rate.

The disposal under our kitchen sink was 12 years old and started leaking from the bottom โ which the tech explained is always an internal seal failure, not a repairable condition. He had a replacement 3/4 HP InSinkErator on his truck, installed it in about 45 minutes, and the kitchen is back to normal. Old unit got pulled, new unit tested clean, no leaks at any connection.
Disposal making a loud rattling noise but still grinding. Tech took out a bottle cap that had gotten past the splash guard and was spinning around the grinding chamber. Cleaned out the chamber, confirmed the impeller wasn't damaged, tested for smooth operation. Twenty-minute visit, everything working perfectly.
Old disposal stopped working completely โ no hum, nothing. I assumed the motor failed. The tech checked the wiring first โ found a loose wire nut at the junction box under the sink that had vibrated loose over the years. Reconnected the wire, reset the overload button, disposal came right on. Would have been embarrassing if I'd bought a replacement unit. Masters Plumbing Service's thoroughness saved me a few hundred dollars.
