Capture the best quality water and get the most out of your rainwater collection system. The Rain Harvesting First Flush Max w/ Catch-All Tee is the first line of defense against contamination. Featuring a large-diameter chamber capable of containing the initial flush and a Catch-All Tee to ensure no water skips across the tee until the first flush of water is complete, you can be sure to capture the best quality water.

Unique Design

To prevent contamination, the design includes a jump which makes it harder for dirty water to skip through. Standard tees can allow water to skip through at less than 1L/second. The Catch-All Tee won't let this happen, ensuring you get clean water every rainfall event.

Space-Saving

Use with any length of pipe to suit your system and installation location. The inlet and outlet on the tee are 3" with an expanding 4-inch chamber, so you can capture 30% more water in the chamber.

The Max Chamber increases the volume of water you can catch in a smaller area. The unit features a large-diameter chamber to divert more water with less space. You'll love the flexibility of our unique design.

How does it work?

• The inlet and outlet on the tee are 3 inches. (Can be modified depending on which adaptors are used).
• The chamber can expand to 4 inches - so you can actually capture about 30% more water in the chamber per meter.

It means you can get the job done with a smaller length of pipe - which means less space on your wall to get the first flush volume you need.
