ASK DANNY: How to flush out downspout debris
What if the downspout leads into the basement into a trap (not sure if that’s the word), and not outside? How can you flush it out with a garden hose?
Thank you. Please advise.
The garden hose should still allow you to flush out the debris. However, sometimes you may need to use a plumber’s snake to dislodge any of the impacted debris.
