The REEFE RainPro RM4000-3 Rain Mains System with PRJ80 Pump includes the RMV3550 valveset to provide a fully automatic rainwater-to-mains switching solution for domestic toilet and laundry supply, as well as small homes, cabins, and outbuildings. Featuring a fully hydraulic Rain Mains valve with no electronics, floats, or solenoids, the system enables fast installation and dependable operation. When rainwater is available, the system supplies pressurised water from the tank, and when the tank is empty or unavailable, it automatically restricts mains flow to conserve water while maintaining supply.
Equipped with a durable PRJ80 jet pressure pump, automatic pressure control, run-dry protection, and thermal overload safety, the RM4000-3 provides consistent pressure delivery with minimal maintenance. With potable-water certification and an integrated dual check valve, this system is suitable for households requiring a simple, efficient, and WaterMark-certified rain-to-mains solution.
