Abstract
A water meter and backflow preventer for use in a water supply system having a meter box includes a housing having water infeed and outfeed openings which are connected to supply water from a main utility pipeline to a water customer domestic system through a pair of infeed and outfeed shut-off valves and a water meter mounted within the housing. A double check valve is installed in the water circuit in the housing to enable use of the double check method of backflow prevention. Test ports are provided through the housing to enable the housing unit to be testable for leaks through the valves. The water meter and backflow preventer combines backflow prevention integrated with an AWWA-approved water meter in one product having the same overall lay length as a current water meter to eliminate the need for re-fitting pipe or using adapters within the meter box.
