Clog Conditions: Outlets Versus Troughs
Drainage trouble usually stems from two distinct debris patterns: an isolated outlet blockage or widespread accumulation across the horizontal channel. Illustrative drainage issues include:
- A single collection of twigs, leaves, or bird nesting material wedged directly over the downspout opening, causing rapid water buildup even if the remaining channel stays clear.
- Organic muck, silt, and decomposed matter settled evenly along the entire trough run, creating slow drainage, standing pools, and localized spillover.
