The parts, from the sink down
The sink flange sits in the drain opening and is held by a mounting ring and snap ring. The disposal hangs from that assembly. Inside, a shredder plate and impellers grind food against a stationary ring, and the pieces wash out through the discharge pipe.
Discharge and trap
The discharge tube leaves the side of the unit and meets a P-trap. The trap holds a water seal that blocks sewer gas, so it must stay full and sloped properly toward the wall drain.
Dishwasher connection
The dishwasher drain hose ties into a small nipple on the disposal housing. A new disposal ships with a knockout plug that must be removed if a dishwasher is attached. Forgetting it makes the dishwasher back up and sit full of water.
Power and switch
Most units are hardwired or plugged into an outlet under the sink, controlled by a wall switch or an air switch. A reset button on the bottom trips when the motor overheats or jams.
What North Davis Sewer District asks you to keep out
The district that treats Clearfield's wastewater advises against sending large amounts of food waste through a disposal. Its guidance also says fats, oils, and grease cannot be stopped by disposal units or by hot water and detergent.
Grease cools inside the trap and the lines beyond it, where it forms a plug. A disposal does not remove that risk, so wipe pans into the trash first.
What the unit handles and what it does not
Soft scraps, small amounts of vegetable trimmings, and food residue from plates are what a disposal is built for. Run cold water before, during, and for several seconds after grinding so the waste travels past the trap and into the main line.
Keep out coffee grounds in quantity, eggshells in bulk, pasta and rice, potato peels, bones, fibrous stalks like celery, and anything that is not food. Starch swells and sets into paste, and fibers wrap around the impellers. Those habits cause most of the kitchen clogs that drain cleaning crews are called to clear.
Quick checks when the disposal acts up
Work through these before assuming the motor is dead.
- Humming but not turning: the unit is jammed, so cut power and free the impellers with an allen wrench in the bottom socket.
- Silent with no hum: press the reset button on the bottom, then check the breaker.
- Water standing in the sink: the trap or line beyond the disposal is blocked.
- Leak at the top: the flange seal or mounting needs resealing.
- Leak at the side: the discharge or dishwasher connection is loose.
- Leak at the bottom: a failed seal inside, and the unit is usually replaced.
Never reach into the unit with your hand, even with the switch off. Use tongs or pliers and cut power at the breaker first.
Safety checklist before you clear a jammed disposal
- Switch off the disposal at the wall and flip its breaker or unplug it. A disposal that restarts under your hand is the main injury risk.
- Never put fingers into the chamber. Use tongs or pliers to lift out a spoon, bone or bottle cap you can see.
- Turn the blades by hand from underneath with the hex socket if your model has one, then press the red reset button.
- Skip chemical drain products. They sit in the chamber and splash when the plumber opens the trap.
- If it still hums or trips the breaker, stop and call a plumber.

North Davis Sewer District serves Clearfield, along with Clinton, Layton, Roy, Sunset, Syracuse, and other nearby communities. The district says to avoid large amounts of food waste through the disposal and states that grease cannot be stopped by disposals or by hot water and detergents. Practical tie-back: a grease habit in one kitchen can plug your own line before it ever reaches the district's pipes.
That matters because the district treats wastewater from roughly 238,000 people across about 80 square miles. Its own guidance asks households to keep fats and food solids out of the system, so scrape plates and wipe pans before they reach the sink.
Clearfield's permit guidance says replacing plumbing fixtures needs no permit, while new or replacement plumbing lines do. Utah licensing law also separates minor fixture repair from first-time installation, so adding a disposal where none existed is plumber territory (our garbage disposal repair service covers swaps). Ask the Clearfield City building department when in doubt.

Installing or replacing a disposal
A swap of the same model is the easiest case. Shut off power at the breaker, disconnect the discharge and dishwasher hose, release the mounting ring, and lower the old unit. The new unit hangs from the same flange, and the plumber reconnects the trap and tests for leaks.
Adding a disposal where there was none changes the drain, adds electrical work, and usually needs a deeper sink flange and a trap re-fit. That is where hiring a licensed plumber makes sense. Installs in Syracuse and Clinton follow the same steps.
Repair, reset, or replace
Use this to judge what the symptom is telling you.
| Symptom | Likely cause | Usual fix |
|---|---|---|
| Hum, no spin | Jammed impellers | Cut power, free with a wrench |
| No sound at all | Tripped reset or breaker | Reset, then test the outlet |
| Slow drain | Clog in trap or branch line | Clear the trap, then the line |
| Leak at the bottom | Internal seal failure | Replace the unit |
| Leak at the flange | Dried putty or loose ring | Reseal and tighten |
| Dishwasher backs up | Knockout plug left in | Remove plug, clear the hose |
What changes the cost of disposal work
Disposal jobs range from a reset to a full replacement. These factors move the price.
- Repair or replace
- A jam or a loose connection is minor. A failed seal or burned motor means a new unit.
- Unit size and quality
- Horsepower and build vary, and a stronger motor handles a household better but costs more.
- Electrical set-up
- Hardwired units, missing outlets, and switch changes add scope.
- Plumbing condition
- A corroded trap or a drain with grease buildup adds work.
- Dishwasher and sink details
- Extra connections, double bowls, and an old flange all add time.
Insurance generally covers sudden and accidental water damage, not wear on the disposal itself, so check your policy before assuming a leak is covered.
Call (801) 207-7520 and the plumber will state the price before work starts.
Disposal questions we hear in Clearfield
Is it okay to put grease down the garbage disposal in Clearfield?
No. North Davis Sewer District states that fats, oils, and grease cannot be stopped by disposal units or by hot water and detergent. Grease sets in the trap and the pipe beyond it.
Wipe pans into the trash first.
Why does my sink fill with water when the dishwasher runs?
A plug in the disposal inlet may still be in place. A kinked hose or a clogged branch line can do the same. The dishwasher cannot drain until that path is clear.
Check the plug first.
Can I install a garbage disposal myself?
A same-model swap is a common DIY job. Adding a new disposal involves first-time fixture installation and electrical work, which Utah licensing law treats differently from minor repair.
Call a licensed plumber for new installs.
Does a disposal need a permit in Clearfield?
Clearfield's guidance says replacing plumbing fixtures needs no permit, while new or replacement lines do. A disposal swap is usually fixture work.
Permit rules vary, so ask the Clearfield City building department.
What should I do when the disposal hums but will not turn?
Cut power at the breaker. Insert an allen wrench into the bottom socket and work it back and forth to free the jam. Press the reset button once the unit moves.
Never use your hand.
When does a disposal problem become a drain problem?
If water stands in the sink after the unit runs, the blockage is likely in the trap or branch line. Running the disposal harder will not clear it.
A plumber can clear it with a cable.
