Garbage Disposal Repair and Installation in San Antonio, TX
A broken garbage disposal can quickly make everyday kitchen cleanup messy and inconvenient. If your disposal is jammed, leaking, making unusual noises, or no longer turning on, Lujan Plumbing can inspect the system and determine what is causing the problem.
We provide professional garbage disposal repair, replacement, and installation for homeowners throughout San Antonio and the surrounding area. We will explain whether the existing disposal can be repaired or whether replacement is the more practical long-term option.

Identification of leaks around the sink flange, dishwasher connection, drainpipe, mounting assembly, or disposal housing.

Removal of an old or damaged disposal and installation of a properly sized replacement for your household and kitchen sink.
New Disposal Installation

Signs Your Garbage Disposal Needs Attention
Some garbage disposal problems can be corrected with a straightforward repair, while others indicate that the unit is nearing the end of its useful life. Contact a plumber if you notice any of the following:
- The garbage disposal will not turn on
- The motor hums, but the grinding plate does not move
- The disposal repeatedly trips or shuts off
- Water leaks beneath the sink when the disposal runs
- The unit makes grinding, rattling, or scraping noises
- Food waste drains slowly or backs up into the sink
- Persistent odors remain after the unit is cleaned
- The disposal vibrates or moves while operating
- The sink flange or mounting assembly feels loose
- The disposal has frequent problems despite previous repairs
A malfunctioning disposal can affect more than kitchen convenience. Leaks beneath the sink may damage cabinets or flooring, while poor drainage can contribute to clogs and standing water. Prompt inspection can help prevent a smaller problem from becoming more disruptive.
Honest Recommendations
Should You Repair or Replace Your Garbage Disposal?
A garbage disposal does not always need to be replaced when it stops working. A jam, loose connection, blocked drain, tripped overload protector, or installation issue may be repairable.
Replacement may be more practical when the disposal has a cracked housing, severe corrosion, damaged internal components, repeated leaks, or ongoing motor problems. An older disposal that requires frequent service may also cost more to maintain than to replace.
Lujan Plumbing will inspect the disposal and surrounding plumbing, explain what caused the problem, and recommend the option that makes the most sense for your home.
Common Garbage Disposal Problems
Jammed Grinding Components
Bones, utensils, fibrous food, fruit pits, and other hard or stringy materials can prevent the disposal from rotating.
Loose or Worn Seals
A worn gasket, loose mounting ring, or failed connection can allow water to leak beneath the kitchen sink.
Clogged Drainpipes
Food waste, grease, and buildup can restrict the drain beyond the disposal and cause slow drainage or sink backups.
Electrical or Motor Problems
A tripped overload switch, failed motor, damaged wiring, or power-supply issue may prevent the unit from operating.
Damaged Disposal Housing
Corrosion or cracks in the disposal body can create leaks that generally cannot be corrected by tightening a connection.
Improper Installation
Incorrect mounting, drain alignment, or dishwasher connections can cause movement, leaks, noise, and poor drainage.
Choosing a Replacement Garbage Disposal
If replacement is necessary, the right disposal depends on how often your household uses it, the available space beneath the sink, the condition of the existing plumbing, and the type of food waste normally processed.
- Motor size: A larger household or frequently used kitchen may benefit from a more powerful motor.
- Physical dimensions: The unit must fit beneath the sink without interfering with drainpipes, storage, or other equipment.
- Noise level: Some models include additional insulation or design features that reduce operating noise.
- Existing connections: The replacement must work with the sink opening, drain layout, dishwasher connection, and available power setup.
- Durability and warranty: Construction quality and warranty coverage may differ significantly between models.
You may purchase your own disposal in advance, but it is helpful to confirm that the model is compatible with your sink and plumbing before ordering it.

Frequently Asked Questions About Garbage Disposals
Why is my garbage disposal humming but not spinning?
A humming disposal is often jammed, meaning the motor is receiving power but the grinding components cannot rotate. Continuing to run it may overheat or damage the motor, so turn it off and have the obstruction or mechanical problem inspected.
Why is my garbage disposal leaking?
A disposal may leak from the sink flange, mounting assembly, dishwasher connection, drainpipe, or the disposal housing itself. The leak location determines whether the unit can be resealed, reconnected, repaired, or needs replacement.
Can a jammed garbage disposal be repaired?
In many cases, yes. If the motor and internal components have not been damaged, removing the obstruction and restoring normal movement may solve the problem.
When should a garbage disposal be replaced?
Replacement may be appropriate when the housing is cracked or corroded, the motor has failed, repairs are no longer practical, or the disposal experiences repeated leaks and jams.
Can I provide my own replacement disposal?
In many cases, yes. Before purchasing one, verify that it fits the available space and is compatible with your sink, drain layout, dishwasher connection, and electrical setup.
Why does my kitchen sink drain slowly?
Slow drainage may be caused by food buildup inside the disposal, a clog in the downstream drainpipe, or an installation problem. The disposal and nearby drain should be inspected to identify the restriction.
Should I use chemical drain cleaner in a disposal?
Chemical drain cleaners may damage plumbing components and can create hazardous conditions for anyone who later services the drain. A persistent clog should be diagnosed and cleared using an appropriate plumbing method.
What should not be placed in a garbage disposal?
Avoid grease, cooking oil, bones, fruit pits, utensils, large amounts of fibrous vegetables, and other hard or stringy materials that may clog or jam the disposal.
