SafeRain is a first flush water diverter valve using flow-rate as the means of diversion as opposed to the container method that traps the first flush of water in a holding container at some point before the tank.

SafeRain units are attached to the pipe that feeds the collected rainwater to the water tank or cistern tank. At the "normal" setting SafeRain will divert approximately 100 litres and has a range of 0-2,000 litres (100mm pipes contain 8 litre/metre).

Below-ground feeder pipes
If your feeder pipes are below ground, stagnant water lying in underground pipes can putrefy due to condensation and light rain washing dust and other pollutants from the roof down into the lowest point in the system.

When rain starts the tainted water is the first to move followed by the sludge. As the rainfall increases water moves faster through the pipe(s) pushing the sludge through to your tank.

SafeRain Reverse-Flow first flush water diverter valve is designed to be installed at the riser feeding the water tank or cistern tank and will dump the initial water away from the tank until the present flow rate point is reached.

Above-ground feeder pipes
SafeRain Horizontal first flush water diverter valve is designed to be installed at the overhead pipes feeding a water tank or cistern tank.

SafeRain Vertical first flush water diverter valve is designed to be installed at the down-pipe where piping is "L" shaped feeding a water tank or cistern tank.
