Irrigation system start-ups may seem easy to do but they're more complicated than you think. Contacting and hiring a trained professional could save you from costly repairs. 

Your irrigation system is complex, and must be pressurized correctly to avoid possible bursts, and breaks in your line. If done incorrectly the drastic change in water flow could create a problem called water hammer, causing damage throughout the system. Once pressured with water the back-flow preventer needs to be inspected to ensure there is no damage from the cold winter months. Each watering zone is then activated, and examined carefully to catch any problems early on. After examining the zones  the spray heads and rotors are adjusted to eliminate dry spots in your lawn. Once the survey of your system is complete the timer will be reset to ensure the zones are watering your lawn correctly leaving you stress free knowing that your sprinkler system is in good hands.
