The RM1500-2 is an automatic hydraulically operated mains to rainwater changeover valve. These changeover valves are ideal for rainwater harvesting - switches from mains to tank whenever tank water is being pumped and automatically defaults to mains in the event of a power or pump failure, and when the rainwater is depleted. This unique rain to mains changeover valve comes with dual 25mm outlets, giving the user flexibility in both domestic and commercial applications. 

IMPORTANT: This product must be used with pumps with an auto restart pressure controller.
