Rain sensor Installing the Sprinkler Heads and Finishing the Accessories and Main Control Panel - Before adding sprinkler heads, flush water through system to clean out any debris.
- Tap into the waterline.
- Attach fitting into the saddle (figure A -- two types of fittings, your choice) and one into the sprinkler head. Be sure to use a smaller, more flexible piping (figure B) to go from the main pipe up to the sprinkler head. This type of piping is more manageable and will curve easily.
- Fill in with some dirt.
- Level the sprinkler head with level of sod (figure C).
- Fill in rest of the dirt and sod.
Tip: To maintain a even water-application rate, it's critical to nozzle the heads accordingly. For example, if you have a 180-degree rotary head and a 90-degree head in the same zone, you'll need to be sure to put twice the nozzle on the 180-degree head as you do the 90-degree head. - If you're at the end of a pipe run and need to install a sprinkler head, here's what you can do: Take a 90-degree barbed elbow fitting and press it into the pipe, then take a riser fitting and screw it into the pipe and attach the sprinkler head to it (figure D).
Suggestion: If you would like to be able to have your water sprinklers turn off automatically if it's raining, you could install a wireless rain sensor (figure E), which has a stack of hydroscopic disks that expand when they get wet, tripping a switch, and shutting down your automatic sprinkler system when it rains! As the disks dry off, they contract and restore the irrigation sprinkler system. - Attach the wireless rain-sensor model to the gutter.
- To get power to the valves, connect wires to controller. One goes to the white or common wire and the other goes to a colored wire.
Note: The controller (figure F) -- installed in the garage for this particular project -- is the brains of the sprinkler system. Each wire connects to a valve, which controls its own timing operation. Be sure to follow the manufacturer's instructions when putting the controller together. - The final step is to check to see if system is working.
