A garbage disposal that's been making grinding sounds for months before stopping entirely often has a seized bearing or cracked impeller โ signs the motor isn't worth repairing. Our techs in Clovis tell you honestly whether a repair or a same-day unit swap makes more financial sense.

Garbage disposal failures have specific, diagnosable causes. Our techs don't just swap units โ they identify what failed and whether repair or replacement is the right call for your situation.
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.
From a simple jam clear to a full replacement with drain reconnection, here's how we handle each garbage disposal scenario in Clovis, CA.
A disposal that hums with no rotation has a jammed impeller plate โ the spinning plate has been stopped by a bone fragment, a piece of silverware that fell in, or hard food buildup around the shredder ring. We use the jam-clearing wrench at the center motor socket to manually rotate the impeller free, remove any obstruction from the grinding chamber, and press the thermal overload reset button before testing.
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).
An unusually loud grinding, rattling, or metal-on-metal sound from a disposal almost always means either a hard object (bottle cap, small utensil, pit from stone fruit) is in the grinding chamber, or an impeller piece has broken and is contacting the shredder ring. We access the grinding chamber safely, remove any foreign objects, and inspect the impeller and shredder ring for damage.
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.
The tech identifies the failure type in minutes: jam test at the motor socket, reset button check, power confirmation at the wire connections, leak source tracing. We know what each symptom means and we go straight to confirming it.
You receive a flat-rate price for the repair option and, if relevant, the replacement option with unit cost included. For a simple jam clear, that's a single, low line item. For a failed motor, we show you the new unit cost and installation price together.
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.

Disposal hummed and wouldn't spin. I'd already tried the Allen wrench trick without success. Masters Plumbing Service's tech came out, worked the impeller free from underneath while removing a piece of broken ceramic that had fallen in โ it had wedged between the impeller and the grinding ring in a way I couldn't have cleared from the top. Cleared the jam, pressed the reset, tested. Five-minute fix. Honest about the call minimum charge, no attempt to upsell a replacement on a perfectly good motor.
After we added a dishwasher, it started backing up every cycle. Masters Plumbing Service found the problem immediately โ the previous installer had forgotten to knock out the dishwasher drain plug inside the disposal inlet. The plug was blocking the drain port. Two-minute fix. The tech also tightened the dishwasher drain hose clamp, which was loose. Never had another backup.
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.

Our trucks carry replacement disposal units in common horsepower ratings for same-day installation when the motor has failed.
