How to Drain a Sink Outside

Outside sinks are much more susceptible to clogs than indoor sinks due to the collection of leaves, twigs, dirt and other outdoor debris that can accumulate in the sink basin. There are a few ways to help return normal water flow to the drain, by clearing any obstructions in pipes. The solutions depend on the severity and depth of the clog. A homemade clog-removal solution may do the trick for minor obstructions, while deeper clogs may require a hand auger.

Things You'll Need

• Clog-removal solution
• Baking soda
• Vinegar
• Plunger
• Hang auger (plumber's snake)

Instructions

1. Remove any debris that may have gathered in the sink (leaves, for example).

2. Allow sufficient time for any water in the sink to slowly drain.

3. Pour a commercial clog-removal solution directly down the drain. The amount will vary depending on the product; refer to the instructions. You will need at least one cup. Wait 15 minutes. Flush warm tap water down the drain. If you wish to avoid using chemical solutions, pour baking soda down the drain, follow by vinegar. Allow it to sit for 15 minutes and then flush with boiling water.

4. Place a plunger in the sink, encasing the drain. Turn on the faucet and allow enough water to cover the cup of the plunger. Plunge the sink drain 15 to 20 times by pushing up and down on the handle.

5. Locate the sink trap beneath the sink and remove the cap. Feed the cable of a hand auger into the drain by turning the crank. Turn the crank clockwise and then counterclockwise once the obstruction is met in order to dislodge it. After dislodging, remove the cable, attach the cap and test the water flow.
