The Maxijet RM-Kit Series offers a Rain/Mains Hydraulic Above Ground Pump System that prioritizes sustainable rainwater use in your home. Rainwater from your tank is pumped and used throughout the house before automatically switching to mains water when needed. This system features an automatic controller for seamless switching and easy installation, with all connections in one spot. By utilizing rainwater first, you can potentially reduce water bills. Remember to consider a separate rainwater tank, selecting the appropriate submersible pump model for your needs, and any local regulations before installing this system.
