First Flush Diverters - In ground or Wall Mount
Helps reduce pollution of rainwater collected in tanks, barrels or cisterns!
• Essential when using rainwater inside or outside
• Amount of water diverted is customized to specific requirements of each roof
• Diverts contaminated water to the garden
• Protects rainwater pumps and internal appliances
How does a First Flush Water Diverter work?
Fitting an appropriately sized water diverter, often called ‘roof washers’, is critical to achieve good quality water. Water diverters improve water quality and reduce tank maintenance by preventing the first flush of water, which may contain roof contaminants, from entering the tank or cistern. They help ensure cleaner water is available for use, which helps protect rainwater pumps and internal household appliances such as clothes washing machines, toilets, hot water systems, etc.
When it rains, water slowly builds up in the roof guttering system before it exits through the downpipe. The first flush of water from the roof can contain amounts of bacteria from decomposed insects, skinks, bird
and animal droppings and concentrated tannic acid. It may also contain sediment, water borne heavy metals and chemical residues, all of which are undesirable elements to have in a water storage system.
Instead of flowing to the rainwater tank or cistern, these pollutants
are diverted with the initial flow of water into the chamber of the water diverter. The water diverters from Rain Harvesting utilise a dependable ball and seat system - a simple automatic system that does not rely
on mechanical parts or manual intervention.
As the water level rises in the diverter chamber the ball floats, and once the chamber is full, the ball rests on a seat inside the diverter chamber preventing any further water entering the diverter. The subsequent flow of water is then automatically directed along the downspout pipe system to the tank.
A Slow Release Control Valve ensures the chamber empties itself after rain and resets automatically. The diverted water need not be wasted water because the drain pipe from the diverter chamber can be fitted to a standard drip irrigation system.
As a rule of thumb, the more water that is diverted the better the quality of water in the tank/cistern.
Multi pipe feed systems -
These water diverters can handle more than one pipe
Single or multiple pipes carrying water from the roof can be directed into an In-Ground Water Diverter.
