Product Info
The Watermarked Action Switch Box is a complete pre-assembled high value mains water diversion system for aboveground tanks that automatically controls the water supply for non-drinking applications (filling the pool, watering gardens, washing the car, washing machine cold water tap and flushing toilets).
The benefit of this system is a significant reduction in installation cost for the builder/plumber/contractor and reduced long-term maintenance costs for the end-user.
Depending on your project requirements, customers can select either the high-value packaged Action Water Switch Box system or the Trickle-Feed Top-Up Unit. All aboveground storage tanks 1000L+ can be configured into a rainwater-harvesting system.
