Step 3 - Cut out a section of pipe
slightly larger than the cut out length of the ball valve
coupling. Determine the length of the cutout by measuring the length from socket to socket
inside the ball valve coupling. If the space for the coupling is cut too large it may prevent the
pipe and the coupling from forming a solid seal. (Unions may be used for easier retrofit
installations.)
Step 4 - Glue the ball valve coupling
into the line. The pipe should fit into both ends of
the ball valve coupling and seat against the ball valve coupling socket. Be sure that the blue
fitting is closer to the back flow preventer than the green fitting and that the flow direction of
the water matches the flow direction arrow on the side of the ball valve coupling.
Step 5 - Attach tubing
to the ball valve coupling. Press the black tube over the
blue fitting on the ball valve coupling. Press the clear tube over the green fitting on
the ball valve coupling. Put tubing clamps over the tubing below the barbed end of
the fitting and squeeze them until they are tightly secured.
