About Twin City Pipeworks
Why Homeowners Trust Us for Garbage Disposal Service
A broken garbage disposal is one of those problems that seems minor until it isn't. If yours is humming, leaking, tripping its reset button, or just dead silent, you need a garbage disposal plumber who can diagnose the real issue and fix it in one scheduled visit. Twin City Pipeworks has been handling disposals throughout the east metro and St. Croix Valley for 20 years, and every repair comes backed by a 1-year warranty on all work. Book online to get on the schedule, or get an instant quote on a common repair with our online tool.
Garbage disposal repairs range from a simple reset or jam clearance to a full unit replacement, depending on what's actually wrong. Age matters a lot here. Most disposals last 8 to 12 years with normal use, and once a unit starts leaking from the body or the motor burns out, repair rarely makes sense over replacement. Labor and parts for a repair typically run less than a new install, but a new install on an older unit can save you from calling again in six months. What drives cost up is access under the sink, hardwired vs. cord-connected setups, and whether your drain configuration needs adjustment during the swap. Budget for a wide range depending on scope. Every job is different, and we give you upfront, per-task pricing before any work begins.
What a Garbage Disposal Plumber Diagnoses on a Service Call
Most disposal problems fall into a short list of categories, and an experienced plumber spots them fast. The unit hums but won't spin? That's almost always a jammed flywheel, not a dead motor. It trips the reset button repeatedly? The motor is overloading, which points to a wiring issue, a failing motor, or something caught in the grinding chamber. Leaks from the sink flange at the top mean the mounting ring has loosened or the seal has failed. Leaks from the side or bottom of the unit mean the internal seals are gone, and that's a replacement call. Knowing which problem you're dealing with before parts get ordered is the difference between a $150 fix and a wasted service call. We don't guess.
Garbage Disposal Not Working: How to Read the Symptom First
Four symptoms send most homeowners looking for help, and each one points somewhere specific. Here's how to read yours before you book.
Garbage disposal not working at all
No hum, no sound, nothing when you flip the switch. Start with power. Press the red reset button on the bottom center of the unit, because an overload trip is the single most common cause of a dead disposal. If that doesn't do it, check the wall switch and the breaker, then confirm the unit is still connected under the sink. If power is confirmed and it's still silent, the internal overload or the motor windings have failed, and a unit that old is usually a replacement rather than a repair. Book online and tell us what you're seeing so we arrive with the right part.
Garbage disposal humming but not turning on
A disposal that hums but won't spin is almost always a jammed flywheel, not a dead motor. Something hard got wedged between the grinding plate and the ring and locked the rotation. The motor is powered but can't turn, and if you leave it humming it will trip the overload or burn out. Cut the power at the switch, then use the hex key in the bottom center port to work the flywheel back and forth until it spins freely. Press reset, restore power, and test with cold water running. If it jams again within a few uses, something is still caught in the chamber or the grinding components are worn.
Garbage disposal leaking from the bottom
Where the water comes from tells you whether it's a repair or a replacement. A leak from the sink flange at the top means the mounting ring loosened or the putty seal failed, and that gets resealed. A drip at the side drain connection is a loose slip joint or a cracked fitting, also repairable. A leak from the bottom of the unit itself is different. That means the internal seals around the motor shaft have given out, and there is no fix for that. A disposal leaking from the bottom gets replaced, full stop. Don't let anyone charge you to seal it from the outside.
"We run the unit, trace the leak to its actual source, and tell you straight whether it's a flange reseal or a replacement before any work begins."
Garbage disposal that keeps tripping its reset
If the reset button pops within a minute or two of running, the motor is overloading. That points to a partial jam still caught in the chamber, a failing motor, or a wiring fault. Clear the chamber with the hex key first. If it keeps tripping after that, the unit needs a plumber, and on a disposal past the 10-year mark it's usually time to replace it. Not sure which bucket you're in? Get an instant quote on common repair tasks, or book online and we'll diagnose it on the visit.
Unjam, Reset, or Replace: How Disposal Calls Actually Go
Garbage disposals are not really a repairable appliance. When one stops working, the answer is almost always to unjam it, reset it, or replace it. A stuck flywheel gets freed with the hex key on the bottom of the unit. A motor that tripped gets reset with the button. If either of those fixes it, you're done. If the motor is dead, the body is leaking, or the grinding components are worn, the unit gets replaced. There's no meaningful middle ground where rebuilding a disposal makes financial sense. Most units run $100 to $250 for the fixture itself, and labor to swap it is straightforward. We'll tell you honestly which situation you're in when we get there. If it can be unjammed or reset, that's what we'll do. If it needs to come out, we carry common replacement units on the truck.
Why Twin City Pipeworks
Key Facts About Garbage Disposal Service
Here's what matters when you're deciding whether to call a plumber or handle it yourself.
Most jams clear without a replacement
A stuck flywheel can often be freed with the hex key port on the bottom of the unit. If it won't budge or keeps jamming, a plumber should check the grinding chamber.
Leaks from the bottom always mean replacement
Internal seals don't get repaired. Once the body leaks, the unit is done. Don't let a plumber charge you to 'fix' a bottom leak.
Twin City Pipeworks carries a 1-year warranty
Every replacement Twin City Pipeworks completes is backed by a 1-year warranty on labor and workmanship. No exceptions.
Catch a leak early and get it scheduled
A disposal leak under your sink can soak the cabinet and subfloor over time. Shut off the supply at the stop valve under the sink and book a repair visit so it gets addressed before the cabinet is damaged.
What Happens During a Disposal Service Call
When a Twin City Pipeworks plumber arrives, the first thing they do is diagnose before touching anything. That means running the unit, checking the drain line, inspecting the mounting assembly, and testing the reset. If the fix is a jam clearance or a reset adjustment, that's done on the spot. If the unit needs replacement, you'll get a straight answer on which disposal makes sense for your sink setup and usage, not whatever happens to be on the truck. Installs include checking the drain connection for leaks and confirming the dishwasher knockout is properly handled if your dishwasher drains into the disposal. The area under your sink gets left clean. The whole visit typically runs under an hour for a straightforward replacement.
When to Call a Plumber vs. Handling It Yourself
There are a few things you can reasonably do yourself before calling. Hit the reset button on the bottom of the unit. Use the hex key in the center port to manually turn the flywheel if the motor hums but won't spin. Run cold water and check whether the drain line from the disposal to the trap is clear. Those three steps handle a surprising number of disposal complaints. Call a plumber when the unit is leaking, when the reset keeps tripping within minutes, when there's a burning smell from the motor, or when the unit is more than 10 years old and acting up. Trying to rebuild or bypass a motor yourself without proper experience usually creates a bigger problem, and a poorly reinstalled mounting assembly can crack your sink flange. Some repairs save you money. Others don't.
Other Plumbing Services That Often Come Up Together
Disposal work frequently uncovers related issues. A corroded flange connection might be the right time to also look at your faucet and fixture setup while access is easy. A drip at a supply connection is worth a leak check while we're under there. If you're doing a kitchen remodel or a full sink swap, Twin City Pipeworks can coordinate the disposal install alongside other fixture work so you're not scheduling two separate visits. We've been doing this long enough to spot the problems you didn't call about before they turn into the reason you call back.

Frequently Asked Questions
How much does it cost for someone to fix your garbage disposal? +
Repair costs depend on what's actually wrong. Clearing a jam or adjusting a reset is on the low end of the scale. Replacing a failed mounting assembly or drain seal sits in the middle. A full unit replacement is the most involved and most expensive option, though disposal units themselves are relatively affordable. Costs vary based on unit size, installation complexity, and whether your setup is cord-connected or hardwired. We use upfront, per-task pricing, so you'll know the number before any work begins.
Can I fix my garbage disposal myself? +
For a jam or a tripped reset, yes. Use the hex key in the port on the bottom of the unit to free a stuck flywheel, then press the reset button. Those two steps clear a lot of disposal complaints. Beyond that, a leaking flange or drain connection and a motor that won't run need a plumber. Getting the mounting torque wrong cracks sink flanges, and a bad drain connection will leak into your cabinet every time the disposal runs.
What is the average lifespan of a garbage disposal? +
Most garbage disposals last 8 to 12 years under normal residential use. Units that grind hard materials regularly (bones, fruit pits, fibrous vegetables) wear faster. Once a disposal hits the 10-year mark and starts showing problems, replacement is almost always more cost-effective than repair. A new unit will grind better, run quieter, and come with a manufacturer warranty in addition to Twin City Pipeworks' 1-year labor warranty.
Does a plumber work on garbage disposals? +
Yes. A garbage disposal is a plumbing fixture. The drain connection, mounting assembly, and sink flange are all within a plumber's scope. A licensed plumber like Dave at Twin City Pipeworks can diagnose the unit, unjam or reset it if that solves the problem, replace it when it doesn't, check the drain line for related issues, and ensure the whole system is sealed and draining correctly.
Why does my garbage disposal hum but not spin? +
A humming disposal with a frozen plate is almost always a jammed flywheel. Something hard got caught between the grinding plate and the grinding ring and locked the motor. The motor is running but can't turn. Try the hex key in the port at the bottom center of the unit to manually free it, then hit the reset. If it jams again within a few uses, something is still caught in the chamber or the grinding components are worn and need replacement.
Why does my garbage disposal leak under the sink? +
Leaks under the sink come from three places: the sink flange at the top (loose mounting or failed putty seal), the drain connection on the side (loose slip-joint or cracked pipe), or the body of the unit itself (failed internal seals). Flange leaks and drain connection leaks are repairable. A leak from the body of the disposal means the internal seals have failed and the unit needs to be replaced. Don't let anyone charge you to seal a body leak from the outside. That's a temporary fix at best.
My garbage disposal is not working, what should I check first? +
A dead disposal is almost always an overload trip. Press the red reset button on the bottom center of the unit, then flip the switch and listen. No change? Check the wall switch and the breaker, and confirm the unit is still connected under the sink. If power is confirmed and it stays silent, the internal overload or the motor itself has failed, and on an older unit that usually points to replacement rather than repair. Book online and tell us what you're seeing so we show up with the right part.
My garbage disposal is humming but not turning on, how do I fix it? +
A disposal that hums but won't turn on is a jammed flywheel, not a dead motor. Something hard locked the rotation, so the motor has power but can't spin. Cut the power at the switch, use the hex key in the bottom center port to work the flywheel back and forth until it moves freely, then press the reset button and test with cold water running. If it keeps humming without turning after that, something is still caught in the grinding chamber or the components are worn and need a plumber.
Why is my garbage disposal leaking from the bottom? +
A leak from the bottom of the unit itself means the internal seals around the motor shaft have failed, and there is no repair for that. The disposal needs to be replaced. This is different from a leak at the sink flange on top (loose mounting or failed putty seal) or at the side drain connection (loose slip joint), both of which are repairable. If the water is tracing from the body of the disposal, don't pay anyone to seal it from the outside. Shut off the supply at the stop valve and book a replacement before the cabinet and subfloor take damage.
How do I free a jammed garbage disposal with an allen wrench? +
Cut the power at the switch first, always. Most disposals use a 1/4-inch allen wrench (also called a hex key) that clips to the underside of the unit or is taped inside the cabinet. If yours is missing, any 1/4-inch allen wrench fits the port at the bottom center. Insert it and turn it back and forth to work the stuck flywheel loose until it spins freely by hand. Pull the wrench, press the reset button, restore power, and run cold water to test. If it jams again within a few uses, something is still lodged in the grinding chamber and it needs a plumber.
