The REEFE RainPro RM4000-5 Rain Mains System with PRJ80 Pump includes the RM1500-2 valve with 25mm (1″) connections to provide a fully automatic rainwater-to-mains switching solution with no pressure loss on the mains supply. Designed for fast and simple installation, the Rain Mains valve uses no electronics, floats, solenoids, or cabling, ensuring dependable operation and long-term reliability. When rainwater is available, the system supplies pressurised tank water, and when the tank is empty or unavailable, mains water is automatically supplied while restricting flow to conserve usage.
Equipped with a PRJ80 jet pressure pump, automatic pressure controller, run-dry protection, and thermal overload safety, the RM4000-5 delivers consistent and efficient water supply for domestic toilets, laundry, small homes, cabins, and outbuildings. With potable-water certification, WaterMark approval, and a fully hydraulic design, the system provides a simple, robust, and highly efficient rain-to-mains solution.
