In—Ground First Flush Rain Water Diverter Kits

Want cleaner cistern water?

First Flush Water Diverters improve water quality, reduce tank maintenance and protect pumps by minimizing the first flush of water, which may contain contaminants from the roof, from enteringthe tank.

Instead of flowing to the water tank, pollutants are diverted with the initial flow of water into the chamber of the water diverter. The first flush water diverters utilize 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 if 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 to the collection tank.

Buried and out of site, an In-Ground Diverter is perfect for sloping allotments. On a site with a minimum 5 degree slope, an In-Ground Diverter allows a 'wet' system to be converted to a 'dry' system.

After rain event when an In-Ground Diverter is installed, not only will the diverter chamber empty, the water held in underground pipes will also drain out through the diverter, converting it to a 'dry' system.

The inlet and outlet on the end caps are 3 inch or 4 inch schedule 40 fittings.
