Delta High Volume Chamber
Easily divert large volumes of first flush with the Delta High Volume Chamber. Using multiple 100mm pipes to create the diversion chamber, the Delta’s revolutionary design makes installation simple. The Delta chamber is customizable up to 2 metres. Every 1m of Delta chamber = 73 litres of diversion.
Integrated Ball and Seat
This unique design ensure that the first flush ball remains close to the seat, even in high flow events, ensuring the diverter seals as soon as the chamber is full. No more lost balls when cleaning your outlet either!

Why Use First Flush Diverters?
Using a first flush diverter improves water quality and reduce tank maintenance by preventing the first flush of water, which may contain roof contaminants (such as sediment, bird droppings, spiders, insects, mosquito eggs and debris), from entering the tank. They help ensure cleaner water is available for use, which protects rainwater pumps and internal appliances.
