Turning on the Water to your Sprinkler System

Spring Start-ups are completed in April and May each year. During the start-up service, water is turned on to the sprinkler system, the controller is reset if needed and sprinkler heads are adjusted to assure proper coverage. If we find any heads or sprinkler parts that need to be repaired or replaced, we’ll bring it to the homeowner’s attention and get approval prior to making any repairs. If the repairs are covered under any warranties, we can take care of that as well.

Tools needed: Flat Screwdriver

Step 1 – Go to backflow device outside. Turn screws (A) so they are perpendicular to the fitting (up and down).

Step 2 – Turn both blue (or green) handles (B &C) so they are perpendicular to the pipe. This means the handle (B) on the left will be up and down, and the other handle (C) will be straight across the pipe.

Step 3 – (not pictured) Go downstairs/outside to where you turn on the water. Close the drain and turn the water on.

Step 4 – Go back outside to the backflow device and turn the handle (C) parallel to the pipe (up and down).  Slowly open until water comes out of bell at the top then quickly open to pressurize valve. You might hear a popping sound.

Step 5 – Turn the other handle (the one on the left)(B) slowly so it is parallel with the pipe (straight across).

Step 6 – Turn on the clock and run the system.

Once you have turned the water on, it’s important to run a test cycle and make sure the sprinkler heads are adjusted for coverage so you’re not watering the sidewalk or hitting the side of your house. You’ll also want to make sure all of the heads are working correctly. Otherwise, you may not realize you have a problem until brown spots appear. Need help with the adjustments or repairs?
