Garbage Disposal Repair in Keller TX: Three Things to Try Before Calling a Plumber

Before calling Polly Plumbing, try these three things. They resolve the majority of garbage disposal problems in under five minutes and cost nothing.

Step 1: Press the reset button. On the bottom of every garbage disposal there is a small red or black button — the thermal overload reset. When the disposal is overloaded or jams, this button trips and cuts power to the motor. The disposal appears completely dead: no hum, no noise, no response to the wall switch. Press the button firmly until it clicks in. Then try the switch again.

Step 2: Use the hex key. If the disposal hums when you flip the switch but does not grind — a low, strained sound without any motor movement — the grinding plate is jammed. Look at the center of the disposal’s bottom for a small hex port. Use the hex wrench that came with the unit (usually stored under the sink) or any 1/4-inch Allen key. Insert it into the port and work it back and forth to free the jammed plate. Then press the reset button, wait 10 minutes, and try the switch again.

Step 3: Check the outlet or circuit breaker. For disposals plugged into an outlet under the sink, confirm the outlet has power by plugging in another device. For disposals wired to a wall switch with no under-sink outlet, check the circuit breaker panel for a tripped breaker.

If all three steps fail to restore the disposal, call Polly Plumbing at (817) 286-3446). Live agents answer 24/7. License RMP-42199.

A Real Call That Ended in Two Minutes

Sandra called on a Tuesday evening. Her disposal had stopped working completely during dinner prep. No noise, no hum, nothing.

Ricky asked her to turn on the switch and listen carefully. Silence — not a hum, just silence.

He walked her through the reset button. She found it on the bottom of the unit, pressed it until it clicked, tried the switch. The disposal ran immediately.

The overload had tripped — she had been grinding a large amount of vegetable scraps and the thermal protection activated. The reset cleared it. Total time from her call to a working disposal: two and a half minutes.

Ricky told her the only thing to know going forward: if the reset button trips again within a few days of the first trip, or if it trips frequently, the motor may be weakening and beginning to fail under normal loads. That is the signal to call for an assessment rather than just resetting and hoping. A motor that trips repeatedly under normal use is a motor approaching end of life.

Sandra did not need a service call that evening. She may in the future — and she will call Polly Plumbing when she does, because Ricky did not try to sell her something she did not need.

When the Three-Step Fix Does Not Work

If the reset, hex key, and circuit breaker checks do not restore the disposal, the problem is one of five remaining issues. Each one has a different answer.

The Motor Hums But Won’t Spin After Freeing the Plate

What it means: The hex key freed the jam but the grinding plate still will not rotate. The impeller may be damaged, or the motor bearings are worn and the plate is binding.

What to do: Call Polly Plumbing. A disposal with a jammed impeller or worn motor bearings cannot be repaired economically — replacement is the correct call. Cost: $280 to $480 for a Polly-supplied replacement unit installed.

The Disposal Leaks From the Bottom

What it means: The internal seals inside the disposal body have failed. Water is draining through the motor housing rather than through the drain connection. This is not a repairable condition.

What to do: Replacement. Leaks from the bottom of the disposal body mean the seals are gone. Cost: $280 to $480 installed.

The Disposal Leaks From the Side

What it means: The drain connection where the disposal connects to the sink drain, or the dishwasher drain line connection, has a failed gasket or loose fitting.

What to do: This is a repair, not a replacement. Ricky tightens or replaces the drain connection. Cost: $150 to $280 for the connection repair at a service call.

The Disposal Leaks From the Top (at the Sink Flange)

What it means: The mounting flange — the ring that connects the disposal to the underside of the sink drain opening — has developed a failed putty seal. Water is coming from where the disposal meets the sink, not from the disposal body.

What to do: This is also a repair — not a disposal replacement. The flange is removed, the old plumber’s putty cleaned out, new putty applied, and the flange reinstalled. Cost: $150 to $280.

The Disposal Runs But Does Not Drain

What it means: A clog in the drain line from the disposal to the trap or the main drain. This is not a disposal problem — it is a drain problem. The disposal itself is functioning. The blockage is in the pipe.

What to do: See our drain cleaning guide for Keller TX. Most disposal drain clogs clear with a plunger or a short snake from the drain side. If the blockage is in the main drain line, it requires professional drain cleaning.

Repair vs Replace: The Honest Framework for Keller Disposals

Repair makes sense when: The unit is under 8 years old. The problem is a jam, a failed drain connection, or a flange leak — none of which involve the motor. The motor runs smoothly when the jam is cleared.

Replacement makes sense when: The unit is 10 or more years old. The motor hums but will not rotate even after jam clearing. The bottom leaks — internal seals are gone. The reset button trips repeatedly under normal use loads. The unit was inexpensive to begin with and the repair cost approaches or exceeds the replacement cost.

The cost comparison: Most Keller plumbers charge $100 to $250 for a service call to diagnose a disposal problem. A Polly Plumbing replacement with a quality Polly-supplied unit runs $280 to $480 all-in. On an older unit with a motor issue, the total cost difference between a repair attempt plus a likely replacement soon after and a direct replacement is often small enough that replacement is the better decision the first time.

Ricky gives you both options with pricing at the service call.

Garbage Disposal Replacement: What Polly Plumbing Installs in Keller Homes

Ricky carries InSinkErator units on the truck for same-day replacement on most Keller service calls. InSinkErator is the most widely available brand for parts and service in North Texas, with a reliable track record in the Keller market.

For most Keller households: A 1/2 HP to 3/4 HP continuous-feed unit handles normal family kitchen use. The 3/4 HP unit is the right choice for larger households or kitchens with high food waste volume — it jams less frequently under load and grinds more completely.

Septic systems: Keller homes on septic systems should use a disposal with a septic assist feature — enzyme injections or micro-drain technology that breaks down waste before it reaches the tank. Ricky notes this during the replacement consultation for any home not on municipal sewer.

What Garbage Disposal Repair and Replacement Costs in Keller TX

All pricing includes parts and labor. Written quote before any work begins. Same-day service available Monday through Friday 8am to 4pm and Saturday 8am to 2pm. No emergency surcharge.

What to Put Down the Disposal (and What Not to Put Down It)

The most common cause of disposal jams and premature failure in Keller kitchens is misuse. A few minutes of knowing what not to grind prevents most service calls.

Never put these down the disposal: Grease, cooking oil, or bacon fat — these solidify in the drain line and cause clogs well downstream of the disposal. Coffee grounds — they accumulate into a dense paste in the trap. Eggshells — the membrane wraps around the impellers. Pasta, rice, and bread — they absorb water and expand into a dense mass. Fibrous vegetables: celery, artichoke leaves, corn husks, asparagus, onion skins. These strings wrap around the grinding components. Fruit pits, bones, or hard seeds.

The disposal handles fine: Soft food scraps, cooked vegetables, small amounts of citrus peels (which also help deodorize), ice cubes (which sharpen the impellers), small fish bones, and most normal table scraps.

Run cold water, not hot. Cold water keeps grease solidified so it grinds and passes cleanly. Hot water melts grease during grinding, allowing it to re-solidify further down the drain.

Run the disposal before it is full. Feed scraps gradually with water running continuously. A disposal jammed with a large load all at once will trip the reset switch every time.

What Polly Plumbing Does on Every Keller Disposal Call

When you call Polly Plumbing for garbage disposal repair in Keller or any surrounding Tarrant County city, Ricky confirms over the phone whether the reset and hex key steps have been attempted. If they have not, he walks you through them before booking a service call — because a reset that takes two minutes over the phone does not need a truck roll.

If the three-step fix does not resolve the problem, he arrives with replacement units on the truck for same-day swap, assesses whether the leak is at the flange, drain connection, or body seal, and gives you the repair and replacement options with pricing before touching anything.

For kitchen drain problems that are separate from the disposal itself, see our drain cleaning guide for Keller TX. For toilet and other bathroom fixture repairs that often go alongside a kitchen call, see our toilet repair guide for Keller TX.

Frequently Asked Questions About Garbage Disposal Repair in Keller TX

My Keller TX garbage disposal is completely dead. What do I check first?

First: the reset button on the bottom of the disposal unit. Press it firmly until it clicks in, then try the wall switch. Second: the circuit breaker panel for a tripped breaker on the disposal circuit, or the outlet under the sink if the unit is plugged in. Third: the hex port on the bottom of the unit — use an Allen key to manually rotate the grinding plate, then press reset and wait 10 minutes before trying the switch again. If all three fail, call Polly Plumbing at (817) 286-3446.

How much does garbage disposal replacement cost in Keller TX?

Replacement with a Polly-supplied unit runs $280 to $480 including the unit and labor. Customer-supplied unit labor only runs $150 to $280. Drain connection or flange leak repair without replacement runs $150 to $280. The $89 dispatch fee is waived for PollyCare members. Written quote before any work begins. Same-day replacement available. Call Polly Plumbing at (817) 286-3446.

My garbage disposal hums but will not spin. What is wrong?

The grinding plate is jammed. Find the hex port in the center of the disposal’s bottom and insert a 1/4-inch Allen key or the hex wrench that came with the unit. Work it back and forth to free the plate. Then press the reset button on the bottom of the unit, wait 10 minutes, and try the switch. If the plate frees but the disposal still will not run, or if it jams again immediately, the impeller is damaged or the motor bearings are worn. Replacement is the correct call at that point. Call Polly Plumbing at (817) 286-3446.

My garbage disposal is leaking. Where is the leak coming from?

Three possible locations. A leak from the bottom of the unit means the internal seals have failed — replacement is required. A leak from the side where the drain pipe connects means the connection gasket has failed — this is a repair, not a replacement. A leak from the top where the disposal meets the sink flange means the plumber’s putty seal has failed — also a repair. Tell Ricky where the water is coming from when you call and he arrives with the right parts. Call (817) 286-3446.

How long does a garbage disposal last in Keller TX?

A quality 1/2 to 3/4 HP disposal lasts 8 to 15 years with proper use. Keller’s hard water has minimal effect on disposal lifespan since the unit is a motor device rather than a pipe. Misuse — grinding fibrous vegetables, eggshells, grease, or coffee grounds — shortens lifespan significantly more than water chemistry does. A disposal that jams repeatedly under normal food scraps is either being misused or is weakening with age. Call Polly Plumbing at (817) 286-3446 to assess.

Should I repair or replace my Keller TX garbage disposal?

Repair is the right call for units under 8 years old with a drain connection leak, flange leak, or a jam that clears cleanly. Replacement is the right call for units 10 or more years old with a motor problem, a bottom leak, or a pattern of repeated jamming under normal loads. Ricky carries replacement units on the truck and gives you both options with pricing before any work begins. Call (817) 286-3446.

Can I replace my Keller TX garbage disposal myself?

A disposal replacement is a manageable DIY project for a confident homeowner — the mounting system is standardized across most brands and the drain connections are straightforward. The main risks are ensuring the electrical connection is safe (especially for hardwired units) and confirming the drain connection does not leak after installation. Polly Plumbing replaces disposals at $280 to $480 all-in including a quality unit with a manufacturer warranty. Call (817) 286-3446 if you would prefer a professional installation with written documentation.
