Unclog Outside Drain -

If water still pools or drains slower than 1 gallon per minute, the blockage may be in the main sewer line or caused by collapsed pipes.

Pour 1 cup baking soda, then 1 cup vinegar down the drain. Cover the opening and wait 30 minutes. Follow with boiling water. This works best for grease or soap buildup.

Feed the snake into the drain until you feel resistance. Crank the handle to break up or hook the clog. Pull out debris, then flush with water.
