Garbage Disposal Repair and Replacement in Capitol Hill Seattle WA 98174
A broken garbage disposal can put a significant crimp in the functionality of your Capitol Hill kitchen. Whether your disposal is humming but not grinding, has stopped working entirely, is leaking beneath the sink, or is producing an alarming grinding or rattling sound, Capitol Hill Plumbing Seattle provides fast, expert garbage disposal service throughout Capitol Hill, First Hill, Madison Valley, and all surrounding Central Seattle neighborhoods. We carry a full selection of garbage disposal units on our service vehicles so that when a replacement is needed, we can often complete the installation in the same visit as the diagnostic call.
Garbage disposals are compact appliances that sit at the junction of your kitchen plumbing and your home's drain system. A disposal problem can be a simple fix or an indication of a larger kitchen drain issue. Our plumbers diagnose disposal problems accurately, distinguish between a repair and a replacement situation, and complete the work efficiently — getting your kitchen back to full functionality quickly.
Common Garbage Disposal Problems We Repair
Disposal Won't Turn On
If your Capitol Hill kitchen's garbage disposal doesn't respond when you press the switch, the most common causes are a tripped internal reset button (on the bottom of the unit) or a tripped circuit breaker in your electrical panel. Before calling a plumber, press the red reset button on the bottom of the disposal unit and try the switch again. If it still won't start, the problem may be a failed motor, a wiring issue, or a failed wall switch. Our plumbers can diagnose all electrical and mechanical causes of disposal failure and either repair or replace the unit as appropriate.
Humming But Not Grinding
A disposal that hums when turned on but doesn't grind is typically jammed — the grinding plate is unable to rotate due to a lodged hard object (a bottle cap, a small bone, silverware, or a large pit). Turn off the disposal immediately if this happens — running a jammed disposal will burn out the motor. Our plumbers can safely clear jammed disposals and, if the motor has been damaged, replace the unit.
Disposal Leaking
Disposal leaks most commonly originate from three locations: the sink flange seal at the top of the unit (where it connects to the sink drain), the dishwasher connection fitting on the side of the disposal, or the drain elbow at the bottom. Each of these leak types has a different repair approach. Flange seal leaks may require remounting the disposal with fresh plumber's putty. Fitting leaks often require tightening or replacement of the fitting clamp or gasket. Leaks from the body of the disposal itself indicate internal seal failure and require unit replacement.
Noisy Disposal — Grinding or Rattling
Abnormal grinding or rattling sounds during operation indicate that a hard object has entered the grinding chamber. Metal objects like silverware or bottle caps are the most common culprits. If you can safely identify and retrieve the object with the disposal powered off, do so. Our plumbers can safely clear the chamber and inspect the grinding components for damage.
Slow or Draining Poorly
If your Capitol Hill kitchen sink drains slowly even with the disposal running, the issue is likely a kitchen drain clog downstream of the disposal outlet, not a disposal problem itself. Our drain cleaning service addresses this — see our Drain Cleaning page for details.

Garbage Disposal Tips for Capitol Hill Homeowners
- Always run cold water for 15 seconds after using the disposal to flush food particles through the drain
- Never dispose of cooking grease, oils, or fats — they congeal in drain pipes
- Avoid fibrous foods like celery, artichoke leaves, and onion skins that can tangle around the grinding plate
- Never put large bones, fruit pits, or coffee grounds in your disposal
- A cup of ice cubes periodically will help sharpen the grinding components
- Keep a small jar of baking soda and vinegar handy — occasionally running it through the disposal with hot water helps neutralize odors
