First Flush 90mm with Max Chamber 100mm and 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.
