The RM1500-2 is an automatic hydraulically operated mains to rainwater changeover valve. It is ideal for rainwater harvesting – switches from mains to tanks whenever tank water is being pumped and automatically defaults to mains in the event of a power or pump failure. This unique valve comes with dual 1″ outlets, giving the user flexibilty in both domestic and commercial applications. This product must be used with pumps with an auto restart pressure controller.
