First Flush w/ Catch-All Tee and Electronic Valve

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.

By setting the regularity of your first flush diversion, you can optimise how often your First Flush Diverter drains.

Do you want the best quality water possible? Set it to a regular reset interval of three days or less.

Do you need to maximise the volume of water your capture? Increase the reset interval to two weeks or more.

Want to start off with a great compromise of water quality and quantity? Try five days.

Easily customise the first flush diverter’s diversion chamber volume to suit your needs before installing it beneath your garden for maximum space efficiency. You can also customise the destination for drained water and connect the diverter to as many downpipes as necessary.

Traditional First Flush Diverter valves have a tendency to clog over time - they only have a tiny hole so it is inevitable. The release valve on the First Flush w/ Catch-All Tee includes a unique funnel design and a much larger draining hole, which means that water drains as it's supposed to and there is far less chance of the unit becoming clogged.
