Diverters

Protect your rainwater quality by diverting the most contaminated water that washes off your roof with the first few millimetres of rainfall.

First, Flush Diverters are installed using a T junction or high flow inlet to which the diversion chamber is fitted. As the chamber fills with the initial dirty water from your roof, a ball rises until it seals the inlet, allowing the rest of your rainwater, which is much cleaner, to flow directly to your tank. In addition, we have an underground option available for wet systems. The same “flushing” can be achieved with a sliding gate valve for wet systems.
