The AcquaSaver valve (also known as the MaxiSAVE valve or the WILO Water Widget) is a fully automatic mechanical rainwater/mains water changeover device designed for pressure pump supply systems for harvesting rainwater for your toilet, laundry and other household applications with automatic mains backup.
The AcquaSaver valve is designed to operate with a pump with an electronic pressure controller with auto restart not requiring a float switch.
The AcquaSaver valve can also operate with any pump with a pressure controller with a float switch.
The AcquaSaver valve comes with dual 1″ outlets, which give you the flexibility to use one or both outlets. This makes the AcquaSaver unique and ideal for domestic and commercial applications.
The AcquaSaver valve will always prioritise the use of rainwater over mains water when rainwater is available, and will automatically switch over to mains water in the event of the rainwater tank running low or electrical failure. When water has been replenished or power has been restored to the pump, the AcquaSaver valve will automatically prioritise back to rainwater.
The pump is only active when rainwater is being drawn from the water tank, it does not operate when the AcquaSaver valve has switched to mains position.
The operating mechanism of the AcquaSaver valve is a unique patent design, it works by hydraulic water pressure created by the pump to close the mains inlet fully so stored water from a water tank will be used without restriction of flow. This ensures an extremely reliable mechanism using few moving parts and no electronic components and no energy consumption.
The AcquaSaver Diversion Valve has proven to be the most reliable mains water diversion valve on the Australian market. Its full brass construction, hydraulically operated with full port flow and pressure when it switches to mains.
