Rain to Mains System DJ72
The Waterpro® RM4072 system offers the same ease of installation and cost-effective design – no cables, no float switches, no solenoid valves, and no electronic control boxes. With the RM4072, you benefit from a simple yet reliable solution that automatically stops mains water supply while rainwater is available for use.
This system is ideal for laundry and toilet supply and is well-suited for small homes or cabins with one bathroom. Important: The RM4072 is not suitable for suction lift applications. For underground tanks, choose the RM5000-2 submersible version instead.
