APPLICATION

• The MHR20 Valve comes with 3/4″ outlet, which makes the system ideal for domestic applications. Certified to: WaterMark ATS 5200.477 WMK 60075 Complies with AS/NZS 3500.1 when installed by a licensed plumber
• The MHR20 Valve is designed to operate with an electronic pressure controller with auto restart not requiring a float switch. This design makes the MHR20 System very simple to install.
• The MHR20 Series is a fully Automatic Hydraulic Rain/ Mains water changeover device designed for pressure pump supply systems in harvesting rainwater for the toilet, laundry and household applications with automatic mains backup.

Note: Should the static mains supply be greater then 400 kPa above the supply pressure of the pump the device will not completely isolate mains water.
