A resetter device is for described use in a water supply system having a meter box and, extending therewithin, a system outlet from a water supply system and a system inlet to a water consumer system aligned on a main water supply axis and spaced apart by a predetermined distance selected to receive a water flow meter in connection therebetween. The resetter has a body defining first and second conduits, and first and second horns. The first conduit has a inlet for connection to the system outlet and an outlet connected to the first horn. The first horn defines a flow path from first conduit to a horn outlet. The second conduit has an inlet at which there is connected, via a joint, the second horn which defines a flow path from horn inlet to the second conduit. The horn inlet and outlet are opposed to each other and disposed along a water meter axis spaced from and lying at an acute angle to the main water flow axis. The horn inlet and outlet receive a water flow meter in flow connection therebetween, with the meter disposed along the water meter axis. The second conduit has an outlet for flow connection to the system inlet. A backflow preventer is disposed between the outlet of the second conduit and the system inlet.
