Description
The RM1500-2 is an automatic, hydraulically operated changeover valve that switches between mains and rainwater. It’s ideal for rainwater harvesting – drawing from your tanks whenever tank water is being pumped, then automatically reverting to mains supply if there’s a power or pump failure. With its dual 1in outlets, this versatile valve suits both domestic and commercial installations. It must be paired with a pump fitted with an auto-restart pressure controller.
