## 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.

Awesome! It works well in my rain water catching system.

### ⭐⭐⭐⭐⭐ Very Necessary for Rain Harvesting
*by S***S on July 15, 2025*

Installed on a customer's rain harvesting system... works great!

### ⭐⭐⭐⭐ Solid system but missing parts
*by B***N on January 13, 2024*

I received this item very quickly however it is missing one somewhat vital part. When I unboxed the item and started accounting for all the parts I found that the flow control valves were not in the box and I was planning on installing this the next day. Fortunately this is a piece I think I can make in my garage.
