Abstract
Alignment and spacing apparatus for use in installing valves such as backflow preventer valves is provided. First and second couplers such as 90 degree elbow joints are each provided with alignment arms extending therefrom. The alignment arms have portions which permit the arms to be coupled to one another. The alignment arms provide for configuring the elbows in a predetermined relationship with one another, such as for providing for seating the alignment arms with respect to each other in a predetermined relationship. In one embodiment, each alignment arm has a flange portion which is seated against a shoulder portion of the other alignment arm in such a way that the elbow joints are connected such that the center line of the inlet and outlet of the elbow joints are substantially parallel and spaced apart a predetermined distance.
