How to Unclog a Double Kitchen Sink with a Garbage Disposal · Step 3 of 7
In this video
Access the underside of the sink to locate the garbage disposal unit. At the very bottom center of the unit, you will find a hexagonal socket. Insert a 1/4-inch Allen wrench (often called a jam-buster wrench) into this socket. Manually turn the wrench back and forth, both clockwise and counter-clockwise. This forces the internal flywheel to move, which will work to dislodge whatever object is causing the jam. Continue this motion until you can feel the flywheel rotate a full 360 degrees freely.
Goal: Free the jammed flywheel.
- It may require significant force to get the flywheel moving initially.
- The video uses a demonstration model to show the process clearly. The hole is in the center of the bottom plate.

FAQs
Why is disconnecting power to the garbage disposal the first step, and how do I do it safely?
Disconnecting power is crucial to prevent accidental activation and serious injury while working inside or near the disposal blades. Locate your home's main electrical panel and switch off the circuit breaker labeled for the kitchen or disposal. If the circuit isn't clearly marked, you can unplug the unit directly from the wall outlet if it's accessible under the sink.
What if the garbage disposal hums but doesn't spin, and what's the first thing I should check?
A humming disposal indicates power but a jam, likely from a hard object lodged between the impellers and the grinding plate. After ensuring the power is OFF, visually inspect the disposal chamber with a flashlight for foreign objects. Then, use an Allen wrench in the hexagonal hole at the bottom center of the disposal to manually turn the motor shaft and free the impellers.
Do I really need all the specialized tools listed, like the Channellock pliers or socket wrench set, for this project?
While a sturdy plunger is essential, tools like Channellock pliers are highly recommended for securely gripping and loosening slip nuts on the P-trap without damaging them. A socket wrench set can be useful for more stubborn connections, especially on metal P-traps, making the job much easier and preventing stripped parts. Having the right tools minimizes frustration and potential damage.
How do I effectively plunge a double kitchen sink when one side is clogged and the other is clear?
To effectively plunge a double sink, you must create a seal on the non-clogged basin to prevent water and pressure from escaping. Use a stopper, a wet rag, or even a helper to hold down a stopper firmly in the non-clogged side. This directs all the plunging pressure towards the blockage in the clogged basin.
