GRAF Platin In-Direct Complete Package Rainwater Harvesting System 1500L | G70185

The GRAF Platin In-Direct Complete Package – 1500L is a fully integrated rainwater harvesting system designed for residential properties seeking a gravity-fed water supply. With a 1500-litre underground tank, this system collects and stores rainwater for non-potable uses such as toilet flushing, laundry, and garden irrigation.

Unlike direct systems, the in-direct setup uses a header tank to distribute water via gravity, reducing pump wear and offering smoother pressure control. The system includes all essential components—Minimax-PRO filter, submersible pump, float sensor and header tank for a complete and efficient installation.
