During recent rainfall, we observed the system in action. It effectively diverted water into our collection barrel, reducing the amount of runoff around our foundation.

We noticed that when water flow was particularly heavy, the system allowed excess to continue down the original downspout path, preventing overflow issues.

The PVC construction feels sturdy and built to last. We expect it to withstand various weather conditions without deteriorating quickly.

While the white color may not blend seamlessly with all home exteriors, its functionality outweighs aesthetic concerns for most users.
