After the long winter, your irrigation system requires more than “just turning on the valve.” Spring activation is a critical, multi-step process that safeguards your system from damage and ensures efficient operation throughout the year.
Our sprinkler start up service carefully reintroduces water, checks for leaks caused by freezing, adjusts components, and sets your controller for optimal watering.
Don’t wait till warmer weather when you are ready to use your irrigation system for the season to call for an appointment. It is best to call early to get on the schedule, even when the snow is falling. At the beginning of each spring, your irrigation system must be properly opened and set up for the coming season. A professional spring startup process should be performed to ensure the system is in top working order. It is NOT simply “just turning on the valve.”
At the spring turn-on service, we will re-install your backflow prevention device (if applicable), pressurize your system, check for leaks, check head operation, adjust heads if needed, program your controller for appropriate spring watering times, and advise you of any necessary repairs or modifications needed.

We recommend scheduling your sprinkler turn on services early—even when snow is still on the ground—to ensure you get your preferred date.
A professional sprinkler activation involves slowly pressurizing the system to prevent water hammer damage, checking all heads for performance flaws, adjusting zones for optimal coverage, and ensuring the backflow device is safely reinstalled and ready for testing. Simply turning on the valve can cause pipe damage if performed incorrectly.
Yes. Most jurisdictions, including Fairfax and Washington DC, require mandatory annual backflow testing. Scheduling this simultaneously with your sprinkler start up service is the most convenient way to ensure full compliance before the watering season begins.
