150mm First Flush Diverter

Description

The 150 mm First Flush Diverter helps deliver cleaner water to your tank by automatically diverting the initial, most contaminated flow of rainwater from your roof. This first flush typically contains dirt, dust, bird droppings, insect debris, and other pollutants.

By installing a first flush diverter, you’re protecting your tank water from contamination and extending the life of your water pump, household appliances, and filtration systems.

This diverter uses a ball and seat mechanism — no moving parts or manual operation required. As water flows through, the initial dirty runoff is captured in a sealed chamber. Once full, the floating ball seals the chamber, directing the cleaner water straight into the tank.

For maximum effectiveness, it’s recommended to install one diverter on each downpipe feeding your tank.
