The built-in dual check valves help\u003cbr\u003eprovide a practical solution to help prevent backflow into\u003cbr\u003ethe primary water source. The RPZ (Reduced Pressure\u003cbr\u003eZone) Dump Valve allows this assembly to dump to atmosphere\u003cbr\u003ewhen the check valves are fouled.\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003e\u003cstrong\u003eOPERATION:\u003c\/strong\u003e Water flows through the turbine section, \u003cbr\u003ecausing the rotor to turn proportionately to the quantity of\u003cbr\u003ewater flowing through the meter. A drive magnet transmits\u003cbr\u003ethe motion of the rotor to a driven magnet located within\u003cbr\u003ethe hermetically sealed register.
