How do I winterize my sprinkler system? |
STEP #1 |
Go to the basement and close the main shut off valve to the sprinkler. |
| STEP #2 |
Hang a bucket on the drain back valve and open part way (this will start draining water from the PVB). |
| STEP #3 |
Go to the PVB and open the 2 small ball valves on the side of the PVB with a screw drive to a 45 degree position (this will allow air into the piping and compete the draining process). |
| STEP #4 |
Turn the handles of the 2 large ball valves with blue handles to a 45 degree position to complete the winterization. |
| STEP #5 |
The drain back valve in the basement can remain open all winter. Should water continue to drip from this valve during the winter, the main shut off valve is leaking and should be replaced by a plumber to avoid freeze damage to your sprinkler system. |
| STEP #6 |
NOTE: If you have a manuel drain in the lowest part in your system it needs to be opened, and left open for the winter season. The manuel drain will then need to be closed up for spring. (This is for systems pre 2004.) |

How do I turn on my sprinkler system? |
STEP #1 |
Go to the Pressure Vacuum Breaker (PVB) located outside the house. |
STEP #2 |
Close the 2 small ball valves on the side of the PVB using a straight blade screw driver (the slots will be in an up and down position when closed.) |
STEP #3 |
Close the 2 large ball valve (blue handles) on the PVB (the handles will be crosswise to the valve when closed.) |
STEP #4 |
Go to the basement and close the drain back valve. |
STEP #5 |
Open the sprinkler shut off valve in the basement. |
STEP #6 |
Go to the PVB and open the inlet ball valve (this is the lowest valve on the PVB with a blue handle). You will hear a “pop” as the PVB seals shut (some water may come out of the top of the PVB at this point – this is normal). |
STEP #7 |
Open the discharge ball valve slowly to a half open position (this is the upper most ball valve with a blue handle on the PVB). This allows the sprinkler main line to fill slowly while keeping pressure in the PVB. After the main line has filled, the valve can be opened full (the handle will be parallel with the ground). You can now check the sprinkler system and be ready for watering this season! |

How do I adjust my Rain Bird sprinkler heads? |
STEP #1 |
Insert tool into pull-up slot, turn 90 degrees, and lift up stem. (A) |
STEP #2 |
Insert the desired nozzle into the nozzle socket, and turn the radius adjustment screw clockwise to secure the nozzle in place. (B) |
STEP #3 |
Insert the selected nozzle's identification plug into the opening on the top of the rotor. |
STEP #4 |
To remove the nozzle, first back out the radius adjustment screw. With a needle nose plier, grasp post under nozzle opening. Remove nozzle. |
|
Note: To lift up stem, insert the tool, or a bladed screwdriver into the slot on the side of the turret cap.

Setting the Arc |
The arc is adjustable from 40 -360 degrees (PC units only). The rotor is factory set to 180 degrees. |
|
| Align Fixed Left Edge: |
STEP #1 |
Pull up turret and turn to the left trip point (counterclockwise). CAUTION: If the rotor does not turn easily to the left, first turn it right (clockwise) to the right trip point. |
STEP #2 |
Next, turn the turret until the arrow points in the direction you want t set the left edge to. |
|
| To Increase the Arc: (C) |
STEP #1 |
While holding the nozzle turret at the fixed LEFT stop, insert tool or screwdriver into the adjustment socket. |
STEP #2 |
Turn the screwdriver clockwise, (+) to INCREASE arc. |
STEP #3 |
Each full clockwise turn of the screwdriver will add 90 degrees of arc. |
STEP #4 |
When the maximum arc of 360 degrees has been set, you will hear a ratcheting noise. Do not adjust the rotor beyond the maximum arc. |
|
| To Decrease the Arc: (D) |
STEP #1 |
While holding the nozzle turret at the fixed LEFT stop, insert tool or screwdriver into the adjustment socket. |
STEP #2 |
Turn the screwdriver counterclockwise, (-) to DECREASE arc. |
STEP #3 |
Each full counterclockwise turn of the screwdriver will remove 90 degrees of arc. |
STEP #4 |
When the minimum arc of 40 degrees has been set, you will hear a ratcheting noise. Do not adjust the rotor beyond the minimum arc. |
 |
STEP #1 |
Insert tool or screwdriver into the radius adjustment socket. (E) |
STEP #2 |
Turn the screwdriver clockwise to reduce radius, and counterclockwise to increase radius |
