How to Make a Clogged Garbage Disposal Drain?

Published in Plumbing Repair 4 mins read

To make a clogged garbage disposal drain effectively, the key steps involve ensuring safety by cutting the power, physically removing accessible debris, and potentially using an Allen wrench or plunger to clear internal blockages.

Steps to Unclog Your Garbage Disposal

If your garbage disposal unit is not draining water properly, it's likely due to a clog. Here are the steps to address this issue and get it draining again, based on common methods:

  1. Prioritize Safety: Turn Off Power

    • Before doing anything else, always turn off the power to the garbage disposal. This is crucial for safety.
    • You can usually do this by flipping the corresponding breaker switch in your home's electrical panel. Verify the unit is off.
    • Disconnecting power is the first and most important step as outlined in the provided reference.
  2. Remove Visible Debris

    • Look inside the disposal drain opening using a flashlight.
    • Use tongs or pliers (never your hands!) to carefully remove any large or visible food scraps, silverware, or other objects contributing to the clog.
    • This step directly corresponds to the reference's instruction to use tools to remove visible debris.
  3. Free the Motor Shaft (If Needed)

    • Locate the hexagonal hole at the very bottom center of the garbage disposal unit.
    • Insert the appropriately sized Allen wrench into this hole. Most disposals come with the correct wrench, often attached to the unit itself or stored nearby.
    • Rotate the wrench back and forth in both directions. This action helps to manually turn the motor shaft and break up any stubborn clogs preventing the grinding plate from moving. This is a key technique mentioned in the reference.
  4. Test the Disposal

    • Reconnect the power to the unit by flipping the breaker back on.
    • Run cold water into the sink.
    • Briefly turn on the disposal to see if it operates and if the water drains.
  5. Address Remaining Clogs

    • If the disposal still doesn't drain or the motor hums without grinding, repeat the steps starting from turning off the power (Step 1).
    • Alternatively, if the water is standing, you can use a plunger specifically designed for sinks. Place the plunger cup firmly over the drain opening, creating a seal, and plunge vigorously a few times. This can help dislodge the clog. Using a plunger is suggested as a follow-up step in the reference if the initial steps don't work.

Tools You Might Need

Successfully unclogging a garbage disposal often requires just a few simple tools:

Tool Purpose
Flashlight To see inside the drain.
Tongs/Pliers For safely removing visible objects.
Allen Wrench To manually turn the motor shaft from below.
Plunger To dislodge clogs using water pressure.

Important Safety Notes

  • NEVER put your hand inside the garbage disposal. Always use tools like tongs or pliers.
  • ALWAYS ensure the power is completely off at the circuit breaker before attempting to remove debris or use an Allen wrench.
  • Even when using an Allen wrench from the bottom, keep fingers clear of the drain opening above.

Following these steps carefully should help you clear a clog and allow your garbage disposal to drain properly once again.
