## Description

Discover the next generation of rainwater collection with the Rain Harvesting First Flush with Catch-All Tee! The Catch-All Tee prevents water skipping across the tee until the first flush of water is complete so you only capture the best quality water. The funnel design of the release valve helps water to drain at the rate it's supposed to, and reduces the risk of the diverter becoming clogged. The diverter has a slow-release valve that drains the chamber as it operates, meaning it will always be ready for the next rainfall without your intervention. Boasting an efficient design and forward-thinking customization capabilities, this first flush will prevent both organic and inorganic contaminants getting into your water tank, and ensure a high standard of quality in the final collection tank.
