All Systems FLOW
2×3, 3×4 & 3×3 Downspouts
Unlike 4 in. pipe that can clog in low-flow conditions, our 3½-inch pipe is suitable for all residential downspout sizes – keeping the lines clean and clog free in both high-flow and low volume systems.
Sediment Control
Using 3½-inch pipe instead of 4-inch helps prevent sediment from collecting in low spots, or ‘bellies,’ which are common in DIY installations. The smaller diameter increases flow pressure, helping to keep the line clear and free of buildup.
Prevents Freeze-Ups
Our 3½-inch pipe holds less standing water and allows faster drainage into the subsoil after rain, helping to prevent freeze-ups and other common winter woes that occur in northern climates.
