PLATIN Filter package 3 House, Minimax-PRO filter internal,
Pump package Home Indirect

The Indirect-supply system is designed to support WC’s, washing machines, irrigation and outside cleaning purposes. Rainwater is collected from the roof of the property and is fed into the underground tank via the downpipes. On entry to the tank, the water passes through a filter, to prevent any debris going into the tank. With this system, there is a pressure sensitive pump located in the underground tank. When a valve or tap is opened, water will be pumped under pressure until the valve is closed, allowing for the system to repressurise turning power off to the pump. From the header tank, the water is gravity fed to the WC’s etc. It is all automatic, whenever there is a demand for water i.e. when the toilet is flushed the harvested rainwater will be gravity fed to the toilet from the header tank and then the header tank is topped up by the pump inside the underground tank. In periods without rainfall the water level inside the underground tank will drop. When the rainwater level is too low the pump will stop pumping harvested rainwater to the header tank. This in turn will result in the rainwater level in the header tank dropping. Inside the header tank there is a floating ball valve which controls the top-up of mains water in periods with no rain. This means that the system maximises the use of all available rainwater. If the system is to be used for garden irrigation, an outside tap should be installed on the pipework directly off the pump. A T-junction can be used to achieve this. This will mean that the garden tap is then being supplied by direct pump pressure. (NB: when the tank is low on rainwater there will be no mains water top up to the outside tap.)
