Garbage disposals are the one fixture where "it's cheaper to replace it" is usually true — and that creates a specific problem for you.
When the honest answer and the profitable answer point the same way, nobody has to work very hard to be believed. A contractor can say "not worth repairing" about almost any disposal fault, be right most of the time, and never be challenged.
Which is exactly why the exceptions matter, and why they're worth naming plainly.
A jam is not a failure. A tripped reset is not a failure. A leak from the mounting flange is not a failure — it's a seal and twenty minutes. A blocked drain beyond the unit isn't a disposal problem at all, and replacing the unit won't fix it.
Those four account for a large share of the calls in this category, and every one of them is a repair on a perfectly good machine.
Tap the call button and describe what's happening. If it's one of the four, we'll say so.
Trusted Plumbing Co. repairs, replaces, and installs garbage disposals across Abita Springs, LA for homes and businesses.
Check these before accepting any replacement recommendation.
A Jam
It hums but won't turn. Power is reaching the motor and something is wedged between the impellers and the grind ring.
Then free it from underneath. Most units have a hex socket in the base and come with a matching wrench. Work the plate back and forth until it turns freely. No wrench? A wooden spoon handle inserted from above, levered against an impeller, does the same.
Then press the reset button underneath and try again. Usually a bottle cap, a bone fragment, a fruit stone, cutlery, or a bread bag clip.
A Tripped Reset
Completely silent, no response at all. There's a button on the underside — usually red — that pops out when the motor overloads and cuts all power until pushed back in.
Most people don't know it exists, which is precisely why "the disposal is dead" is such a common and such a wrong conclusion.
Also check the breaker, and whether the unit is plugged in where it's a plug-in installation.
A Flange Leak
Water from the top, where the unit meets the sink. The mounting flange seal has failed.
A reseat with fresh sealant and correct tightening. A repair, not a replacement — and one that's frequently misdiagnosed as a dead unit because "it's leaking" gets treated as one condition when it's three.
A Blocked Drain Beyond the Unit
It grinds perfectly and the sink fills. The disposal is doing its job and the waste has nowhere to go — the trap or the line beyond is blocked, usually with grease or accumulated debris.
Replacing the disposal changes nothing here. It's drain work, and it should be billed as drain work.
Because sometimes it is, and pretending otherwise would be its own dishonesty.
Internal seals have failed and water has been inside the motor housing. These are sealed assemblies not designed to be opened. That unit is finished, and anything sold as a repair for it isn't one.
Usually after being run against a jam.
Producing grinding and vibration that isn't a chamber obstruction. A motor condition, not an adjustment.
Which older and cheaper units do.
From worn impellers and grind ring after years of use.
Which is common — most units aren't built to be rebuilt, and the honest economics rarely favour trying.
Disposal repair is genuinely limited compared with most plumbing. There's a handful of serviceable faults, and beyond those the cost of parts and labour approaches a new unit. What you're owed is a clear answer about which side of that line you're on — not a repair attempt billed at replacement money, and not a replacement sold for a jam.
Three positions, three completely different outcomes — and this is where a replacement recommendation should be challenged most closely.
The mounting flange seal. A reseat — a repair. Common, quick, and frequently misdiagnosed.
The discharge outlet or the dishwasher connection — a hose, a clamp, or a gasket. Also a repair.
Different entirely. Water from the body means internal seals have failed and water has been in the motor. That unit is finished.
So "it's leaking" is not a diagnosis. Two of the three positions are inexpensive fixes, and only one ends the unit. Ask where — and if someone can't tell you, they haven't looked properly.
Worth knowing, because most of these are self-inflicted and every one of them is avoidable.
Being run against a jam. Holding the switch while the motor strains is the fastest way to destroy one — and the single most common way a repairable jam becomes a genuine replacement.
Jam, tripped reset, flange leak, blocked drain. All repairs on a working machine, and all commonly sold as replacements.
Top, side, or bottom. Two are cheap repairs and one is terminal — and "it's leaking" isn't a diagnosis.
Reset button, jam wrench, breaker. If one of those is your answer, you keep your money and we don't take a booking we didn't need.
A leaking housing, a burnt-out motor, or failed bearings genuinely end a unit, and we'll say so plainly.
A disposal grinding perfectly while the sink fills is not a disposal fault and shouldn't be billed as one.
If yours has failed and you rarely used it, a plain waste and trap is cheaper and simpler.

The reset button on the underside. It pops out when the motor overloads and cuts all power until pushed back in, and most people don't know it's there. If it's already in, check the breaker and whether the unit is plugged in.
That's a jam, not a failure. Switch it off at the wall immediately — running against a jam is what actually burns these units out — then fit the hex wrench into the socket underneath and work the plate back and forth until it turns freely.
No. Use tongs or long-nosed pliers with the power off at the wall, or free it with the wrench from underneath. There's no version where reaching in is the right move.
Depends entirely where from. From the top where it meets the sink is the flange seal — a reseat. From the side is a discharge or dishwasher connection. From the bottom of the housing means water has been in the motor, and that one is genuinely finished. Two of three are cheap repairs.
Then it isn't the disposal. The unit is doing its job and the waste can't get away, which means the trap or the line beyond is blocked. Replacing the disposal wouldn't fix it, and it should be billed as drain work.
Frequently, yes — and that's exactly why the exceptions are worth naming. Most units aren't built to be rebuilt, so motors, bearings, and corroded housings are replacements. But jams, resets, flange seals, and drain blockages are not, and they're common.
Yes, despite what you may have heard. Grounds settle downstream as a dense sludge. Eggshell membranes wrap the impellers and the shell becomes a grit that accumulates. Both belong in the bin.
Cold, always, and running well after you've finished. Hot water melts fats so they travel further before setting, which moves your future blockage somewhere less accessible.
Several years with reasonable use, considerably longer if it's never run against a jam and never fed things it can't handle. Heavy use and hard items shorten it markedly.
Frequently the knockout plug in the disposal's dishwasher inlet, which has to be removed at installation and sometimes isn't. Otherwise a blocked connection hose. Both are straightforward repairs.
Not necessarily. If yours has failed and you rarely used it, a plain waste and trap is cheaper, simpler, and one less thing to go wrong. We'll say so rather than selling you a replacement by default.
"Cheaper to replace it" is usually true here, which is precisely what makes it easy to say when it isn't. A jam, a tripped reset, a flange seal, and a blocked drain beyond the unit are all repairs on a perfectly good machine — and all four get quoted as replacements by people who never asked which one it was.
Trusted Plumbing Co. names the exceptions upfront, gives you the free checks before booking, asks where a leak is before quoting anything, and is equally straight when replacement genuinely is the right call.
