First Flush Water Diverters improve water quality and reduce tank maintenance by preventing the first flush. The first flush of rainwater may contain roof contaminants from entering the tank. They help ensure cleaner water is available, protecting rainwater pumps and internal household appliances such as clothes washing machines, toilets, hot water systems, etc.

Benefits
Get cleaner water in your tank
The Maelstrom®’s ultra-fine secondary filter removes particles down to 180 microns – 5 times finer than standard rain heads and pre-tank filters. This gives you cleaner, better quality water and lowers the volume of sediment putting pressure on your tank pumps and post-tank filters.
Get more water, faster
The Maelstrom® eliminates the problem of water splashing off your tank inlet screen, especially at high flow rates. Its phenomenal water catchment efficiency (96% at 3,600 litres/hour in wet systems) gives you more water, faster, so you can take full advantage of every raindrop.
Get water effortlessly
The Maelstrom®'s initial 2mm filter diverts leaves and debris which are then flushed out during rainfall events. Because the revolutionary design is low-maintenance with no mechanical parts, it does this with minimal effort from you.
