Step 1

 Smooth PVC pipe ends with utility knife

From lengths of 3/4" PVC pipe, cut two pieces 60" long, one piece 57" long, and four pieces 30" long. Use a file or utility knife to clean up the ends.

Step 2

 PVC fittings for sprinker

On a 60" pipe, use the printed markings and a straightedge to draw a pencil line down the length of the pipe. Starting and ending 2" from each end, drill 1/16" holes along the line about every inch. Repeat for the other 60" pipe. Check that the PVC fittings slip smoothly onto the pipe ends.

Step 3

Threading hose adapter onto pipe fitting

Cut one of the 30" pipes in half. Use PVC cement according to the manufacturer's instructions to join a 3/4" tee to the two pipes; let dry. Screw a hose adapter onto the threaded opening of the tee and tighten. Then measure and cut the assembly to 30" long.

Step 4

 Applying PVC cement to pipe

Rinse the cutting and drilling debris from all the pipes and let dry before putting the pieces together. Assemble the two V-shape ends using side outlet elbows and the 30" pipes. Then add elbows to the ends of the pipes. Attach the 57" pipe without sprinkler holes to the side outlet elbows using a male adapter at each end; attach the 60" pipes with holes to the elbows. Rotate the pipes so the water will spray inward as the sprinkler rests on the ground.

Step 5

Attach a garden hose to the adapter. Lay a toy water slide or plastic tarp beneath the sprinkler, turn on the water, and let the fun begin. You can also stand the sprinkler on end so kids can run through it.

Good to Know

Except for the tee with the hose adapter, you don't need PVC cement to hold this sprinkler together. If you want to use cement for all the connections, first test how the sprinkler works hooked up to a garden hose and fine-tune the assembly. Working on one joint at a time, dry the pipes and fittings, apply PVC cement, and press the parts together.
