A jammed, leaking, or dead garbage disposal can bring your kitchen to a standstill. PlumbSmart Plumbing & Drains provides honest diagnosis, clear options, and lasting repairs so your kitchen sink stays in service.
The garbage disposal is one of the most frequently used fixtures in any kitchen, yet it rarely gets attention until something goes wrong. When it hums without grinding, refuses to turn on, or starts draining slowly, the problem can range from a simple reset to a worn motor, a failed seal, or a clog deeper in the drain line. Getting the diagnosis right the first time saves you money and prevents a minor nuisance from becoming a flooded cabinet.
PlumbSmart Plumbing and Drains has been serving Asheville and surrounding Western North Carolina communities since July 2008. As a family-owned, licensed, and insured plumbing company, we approach every garbage disposal call the same way we approach any repair: with a clear explanation of what we found, multiple options for fixing it, and set pricing so you know the cost before any work begins.
Whether your disposal is leaking from the sink flange, the side discharge, or the bottom of the unit, or whether it has simply stopped responding entirely, our licensed plumbers can trace the source of the problem and walk you through your repair or replacement choices. We hold North Carolina plumbing license number 29593 and are members of the PHCC, the Plumbing-Heating-Cooling Contractors Association.
Symptom: You flip the switch and hear a low hum or buzz, but nothing spins and the water does not drain.
Solution: This almost always means the grinding plate is jammed. A plumber uses an Allen wrench in the center socket to manually free the plate, removes the obstruction, then resets the overload protector button. If the motor windings have burned out from the jam, unit replacement is recommended.
Symptom: Flipping the wall switch produces complete silence, no hum and no sound of any kind.
Solution: The plumber first checks the reset button on the bottom of the unit and tests the wall switch and outlet for power. If power is present but the unit still does not respond, the motor or control board has failed and the unit needs to be replaced.
Symptom: Water backs up in the sink basin and drains very slowly even when the disposal itself grinds normally.
Solution: Slow drainage usually points to a partial clog in the P-trap, the horizontal drain line, or further down in the drain stack. A plumber clears the obstruction, inspects the trap for grease buildup, and may recommend a video camera inspection if slow draining recurs, especially since PlumbSmart includes a free camera inspection with every drain clearing service.
Symptom: Water appears inside the cabinet directly below the sink opening where the disposal mounts to the drain.
Solution: The mounting flange uses a plumber's putty seal and a three-bolt mounting assembly. Over time the putty dries, the mounting bolts loosen, or the flange itself corrodes. A plumber reseals the flange with fresh putty and re-tightens or replaces the mounting hardware. In severe corrosion cases the flange itself is replaced.
Symptom: Water drips from the dishwasher inlet port, the drain outlet connection, or from the bottom of the disposal housing itself.
Solution: Side leaks are typically loose hose clamps or a cracked inlet gasket, both of which are quick fixes. A leak from the bottom of the housing means the internal seals have failed, which is not repairable and requires unit replacement. A plumber will identify which location is the source before recommending a course of action.
Symptom: The disposal runs but makes a loud metallic grinding, clanking, or rattling sound that was not present before.
Solution: Foreign objects such as small bones, fruit pits, glass fragments, or silverware are the most common cause. A plumber safely removes the object using retrieval tools, never by reaching into a live disposal. If the grinding ring or impellers are damaged, the unit is evaluated for repair versus replacement based on age and condition.
When a PlumbSmart plumber arrives for a garbage disposal call, the first step is a thorough inspection of the entire drain system, not just the disposal itself. Many disposal complaints are actually symptoms of a drain line or venting issue that would persist with a brand-new unit. Identifying the true source of the problem is the only way to make sure the repair actually solves it.
If the disposal can be repaired, we carry common replacement parts and complete the work in a single visit whenever possible. If the unit needs to be replaced, we present you with options at different price points and explain the differences in motor size, noise insulation, grinding stages, and warranty coverage so you can make an informed decision. We never recommend replacement when a repair will genuinely solve the problem.
Replacement involves removing the old mounting assembly, cleaning the sink flange area, applying new plumber's putty, installing the new mounting hardware and unit, reconnecting the dishwasher drain line if present, and testing both the disposal and the drain line for leaks and flow. The job is left clean and dry before we consider it done.
Homeowners can extend the life of their disposal by avoiding hard items like fruit pits, bones, and ice, by running cold water before, during, and after grinding, by cutting large food scraps into smaller pieces before feeding them in, and by never pouring grease or fibrous vegetables like celery into the unit. If a disposal is more than ten to twelve years old and experiencing repeated problems, replacement is often more cost-effective than continued repairs.
PlumbSmart uses set pricing, so you know exactly what the repair or replacement will cost before the work begins and there are no surprises on the invoice.
We present repair and replacement choices at different price points so you can decide what makes the most sense for your budget and the age of your plumbing.
Every service PlumbSmart performs is backed by a 100% satisfaction guarantee, giving you confidence that the job will be done right.

Asheville and surrounding Western North Carolina communities present some specific conditions that affect kitchen plumbing. Older homes in historic neighborhoods often have cast-iron or galvanized drain lines that narrow over decades of buildup, making a slow-draining disposal a more serious concern than in a home with newer PVC piping. Freezing winters can stress pipe joints and connections under kitchen sinks, especially in homes with exterior or crawl-space plumbing runs. Homes on private wells may have harder water that accelerates corrosion on metal mounting flanges and fittings. Whether you are in an older bungalow near downtown or a newer home on the outskirts of the region, PlumbSmart has been diagnosing and solving garbage disposal and kitchen drain problems throughout Asheville and Western North Carolina since 2008.
Age and the nature of the problem are the two biggest factors. A disposal that is less than eight years old and has a mechanical jam or a leaking flange is usually worth repairing. One that is over ten years old, has a failed motor, or leaks from the bottom of the housing has typically reached the end of its service life. A PlumbSmart plumber will inspect the unit and give you an honest assessment of both options along with pricing for each.
It is safe to use the hex wrench socket on the bottom of the unit to manually rotate the grinding plate, as long as the power switch is off and the unit is unplugged or the breaker is off first. You should never reach into the disposal opening with your hand under any circumstances. If the manual reset and the hex wrench method do not free the jam, call a plumber rather than forcing the unit.
A leak from the very bottom of the disposal housing is caused by failed internal seals between the motor compartment and the grinding chamber. This type of leak cannot be repaired by tightening connections or replacing gaskets because the seals are factory-installed inside the sealed housing. Replacement of the unit is the correct solution, and it is worth having a plumber confirm the leak source before you purchase anything.
Yes. The dishwasher drain hose typically connects to an inlet port on the side of the disposal. If the disposal is clogged, that clog can cause dishwasher water to back up into the bottom of the dishwasher tub. Clearing the disposal drain or replacing the unit usually resolves the dishwasher drainage problem at the same time.
When drain clearing is performed as part of the service, PlumbSmart includes a free video camera inspection with every drain clearing. This lets us confirm the line downstream of the disposal is clear and in good condition, not just the disposal itself.
Soft food scraps, cooked vegetables, and small amounts of citrus peels are generally fine. You should avoid hard items like fruit pits, bones, and seafood shells, fibrous materials like celery stalks and corn husks, starchy foods like pasta and potato peels in large quantities, and any grease or cooking oil. Running cold water for about fifteen seconds before and after grinding helps flush the line and keeps fats solidified so they pass through rather than coating the pipe walls.
Yes. PlumbSmart offers Piper Protection Plans at two levels: the Comprehensive plan at fourteen dollars per month and the Premium plan at thirty-five dollars per month. These plans are designed to help homeowners stay ahead of plumbing issues. Contact us or visit the website for details on what each plan covers.
