ABSTRACT:
A water distribution system condition testing apparatus includes a pressure sensing body, a pressure measuring gauge and an one-way flow control actuating member. The pressure sensing body has an internal chamber and is connectable with the user's side of a meter setter which has an internal one-way flow control valve therein adapted to open in response to flow therethrough from an upstream source and to close in response to attempted flow therethrough from a downstream source. The pressure measuring gauge is mounted to the pressure sensing body in communication with the internal chamber thereof. The actuating member has a passageway therethrough to communicate with the internal chamber of the pressure sensing body. The actuating member is relocatable relative to the pressure sensing body between outer and inner displaced positions. At the outer position, the one-way flow control valve is forced open in response to attaching the pressure sensing body to the flow control valve so that testing of the user's water distribution system for a cross connection with a private water source can be performed. At the inner position, the one-way flow control valve remains closed in response to attaching the pressure sensing body to the flow control valve so that testing of the one-way flow control valve for backflow leakage can be performed.
