Sprinkler System Installation Guide – Rain Bird: Sprinkler …

Okay, the planning's done, you've bought all the parts, now you're in the yard, shovel in hand, ready to start. In this helpful video, we'll show you the steps to a perfect sprinkler system installation, including trenching, connecting the water source, installing shut-off valves, working with PVC pipe, building a valve manifold, connecting wires, installing sprinklers and flushing your system.

Place a stake or flag at every sprinkler location as indicated on your layout. Use string to show where the pipe will run.

STOP! Make sure you know where all gas lines, power lines and cable TV lines are before you start to dig. Be sure to call your utility companies if you need help.

Dig trenches following the string. Mark the sprinkler locations with flags or the stakes. Typical trench depths range from 6 to 12 inches.

To run pipe under existing walkways you can "drill" using water pressure. Get a piece of PVC long enough to go under the walk, glue a slip-female thread adapter to one end and attach a hose. On the other end glue a slip-male thread adapter and connect a Jet Spray Nozzle (available at most home improvement and home & garden retailers).

Dig your trench up to the walk on both sides. Now turn on the water and work your way through. It may take a while, and it will get muddy so turn off the water once in a while to let the water soak in.

To make trenching easier ask your local tool rental supplier about a "power trencher." If you are using a Poly Pipe, ask about a pipe pulling machine, which will bury pipe without digging up your lawn. Be sure to put enough space between valves on the manifold so that they can be removed in case they ever need to be replaced.

Hook up your water supply. Did you check with your Rain Bird Dealer to find out which connections are right for our local codes and conditions?

Assemble your valve manifold. Connect the back-flow preventer if required.
