Next, cut four 1 ½-inch lengths from leftover PVC pipe to serve as connectors between the L and T joints. Slip one of the 1 ½-inch PVC lengths into an end of each L fitting, and fit it into the open end of each T (see photo). Aim it down toward the ground.
Tip: For a snug fit, use fine- to medium-grit sandpaper to sand ends of cut pipes; remove dust, then wiggle fittings over the ends.
