Debris and Drainage Conditions
Tree cover and structural layout influence how quickly troughs collect organic material. Accumulations of leaves, twigs, pine needles, or airborne silt restrict the flow of water toward the outlets.
- Troughs filled with decaying foliage or seed pods
- Downspout strainers obstructed by roof grit and twigs
- Standing water caused by weighted, sloping sections
- Organic compost building up in shaded drainage corners
