If the clog is in the downspout, you may only need to clean the gutter and downspout screens. However, if the clog is in the main storm drain, you may need to involve a professional plumber.

Tools needed:

  • Plunger
  • auger (also known as a drain snake)
  • Snaking equipment
  • Bucket
  • Water hose

1. Clear the immediate area around the downspout and storm drain of any debris.

2. Remove any visible obstructions from the downspout, such as leaves or branches.

3. Use a plunger to create suction on the clogged area, holding the plunger firmly in place for several seconds. Release slowly and repeat as needed.

  1. For more severe clogs, use the auger (drain snake) to break up the blockage. Feed the snake through the downspout or storm drain until you feel resistance.
  2. Once you locate the clog, use the rotation handle of the auger to break it up.

4. Repeat the plunging process after breaking up the clog to ensure it's fully clear.

5. Use a water hose to ensure water flows freely through the system.

Clearing a Clogged Main Storm Drain

If the clog is in the main storm drain and you've attempted to clear it yourself, it's best to consult a professional plumber for assistance. They can help determine the cause of the blockage and provide a more effective solution.
