This connection directs roof runoff straight into the new 4-inch PVC drain line, where it can flow toward the existing curb outlet instead of emptying on to the patio and flooding it and creating soggy areas in the yard.
We used a wye and 45-degree connection to introduce the water gradually in the direction of flow. This smoother transition creates less resistance than a sharp 90-degree tee and helps reduce the chance of backups during heavy rain.
Once all three downspouts are connected, the system will manage both roof runoff and surface water collected by the three 9” × 9” basins.
Small details underground make a big difference when the rain starts falling!
