A method and device for pressure testing a pipe line is provided wherein a fitting is inserted into the pipeline by inserting male ends of the pipeline into female ends of the fitting to define a flow path through the fitting extending along a longitudinal axis. The fitting has an internal recess cooperating with a test slide to block flow through the fitting. An externally accessible port allows insertion and removal of the test slide. The test slide has an internal recess in which a pressure release slide moves to open a hole to release pressure, and to close the hole to block flow through the fitting for pressure testing. After testing and the release of the fluid test pressure, the test slide is removed and a finish slide is inserted into the recess. The finish slide has an opening located and configured to coincide with the flow path through the male ends of the pipes, and to block the recess to provide a substantially uniform, cylindrical flow path through the fitting.

A method and device for pressure testing a pipe line is provided wherein a fitting is inserted into the pipeline by inserting male ends of the pipeline into female ends of the fitting to define a flow path through the fitting extending along a longitudinal axis. The fitting has an internal boss extending around a circumference of the flow path and extending radially inward toward the centerline a distance corresponding to the wall thickness of the mating male ends of the pipes so the pipes and boss define a periphery of the flow path through the fitting. A recess is formed in the boss to sequentially receive two slides. An externally accessible port allows a test slide to be inserted into the recess, with the test slide sealing against the walls defining the recess to form a fluid-tight seal for pressure testing the line. The test slide is removed and a finish slide is inserted into the recess. The finish slide has an opening located and configured to coincide with the flow path through the male ends of the pipes, and to block the recess to provide a substantially uniform, cylindrical flow path through the fitting.

Method and apparatus for pressure testing pipe lines

A stub-out bar has a first bar telescopically and slidably receiving a second bar. Holes and slots are formed on the first bar and the second bar, respectively. While attaching a fixture on the stub-out bar, one of the holes is aligned with one slot to allow a fastener to thread through. The first and the second bars each has a bendable tab extending from a front plate thereof. The bendable tabs are positioned at two opposite ends of the stub-out bar such that the stub-out bar can be mounted in different surfaces of joists by simply bending the bendable tabs. The stub-out bar has an open cross-section, in a box-shape. The first and second bars are made of a sufficiently heavy gauge of metal that heavy-duty applications such as bathroom tub and shower fixtures can be supported.
