How to Unclog an Outside Drain Hole

Purchase a hand auger with a minimum length of 3 feet. Because outdoor drains are typically larger than indoor drains, you'll need an auger capable of reaching deep into the drain to remove debris. A hand auger is scaled-down version of its larger counterpart used by plumbing professionals. It features a long, flexible cable with a corkscrew tip. The handle rotates, thus causing the corkscrew at the end of the cable to rotate. This circular movement allows the auger to grab hold of large and small debris.

Place latex gloves over your hands and insert the hand auger into the outdoor drain. Continue to push the auger deep into the drain until you feel resistance, which means you have reached the debris clogging the drain.

Rotate the handle at least five times to secure the debris on the corkscrew. Gently lift the auger out of the drain.

Remove the debris from the tip of the auger and discard into a trash bag. Insert the auger back into the drain until you reach the area of the clog, repeat the rotational movement of the handle to remove any remaining debris. Gently lift the auger out of the drain and discard the debris. Repeat until you feel the drain clog is removed.

Pour 1 gallon of water down the drain. Monitor the drain to determine if the water is sitting stagnant or if it is draining properly. If the water is draining, continue to use the hand auger until all debris is removed.
