First Flush Max w/ Catch-All Tee

The Max Chamber increases the volume of water you can catch in a smaller area – thanks to its large diameter chamber. It means you can divert more water with less space, giving you the flexibility to fine tune your system easily.

We've also included the Catch-All Tee to ensure no water skips across the tee until the first flush of water is complete – which means you only capture the best quality water.

Benefits

More First Flush with less space

The Max Chamber increases the volume of water you can catch in a smaller area – thanks to its large diameter chamber. It means you can divert more water with less space, giving you the flexibility to fine tune your system easily.

How does it work?
- The inlet and outlet on the tee are 90mm (or 80mm, 3", or other depending on which adaptors are used).
- The chamber actually expands to 100mm / 4" - 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.

Benefits

Catch-All Tee improves clean water yield

The Catch-All Tee ensures no water skips across the tee until the first flush of water is complete – which means you only capture the best quality water. The unique design incorporates 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, which means you only get clean water in your tank.
