Drip irrigation is very efficient. Water is put exactly where it's needed-at the root system of the plants. No water is wasted due to runoff or evaporation.
This is my entry for the Get in the Garden contest. I hope you like it!
Step 1: Dripper Materials
4 4" long pieces of 1/2" PVC
2 36" long pieces of 1/2" PVC
2 90 degree elbows for 1/2" PVC
1 four way connector for 1/2" PVC (a tee connector could be used here)
1 female hose connector for 1/2" PVC
1 male connector for 1/2" PVC (if a tee connector is used, this isn't needed)
2 end caps for 1/2" PVC
1 1/16" drill bit
Step 2: Mark and Drill Drip Holes
Once the hole locations are marked, drill 1/16" holes at each mark. Please note that the holes ONLY GO THROUGH ONE SIDE OF THE PIPE. DO NOT DRILL THROUGH BOTH SIDES OF THE PIPE!
Step 3: Glue on the Elbows
First, prime both the ends of the drip pipe and the inside of the elbows. The primer I'm using is purple. You can also get clear...
Once both pieces have been primed, apply glue on the end of the pipe, the put the elbow on.
Remember that the holes will be on the bottom of the dripper, so the elbows need to be put on to allow this...
Step 4: Connect the Drip Pipes
Then glue the two sides to the four way connector.
Step 5: Water In, Water Out
Glue the other 4" pieces onto the four way connector. Then add the male connector to the side between the drip pipes, and the female connector to the side that will be sticking out. The garden hose is connected to the female connector.
I realize that's kinda confusing...check the picture for clarification.
