Winterization We have completed a thorough winterization of your irrigation system. Please leave all irrigation shut-off valves closed to prevent re-introducing water into your system, which could cause freeze damage. If you notice any water dripping outside, or icicle formations on irrigation pipes, please call us to schedule having your shut-off valve replaced immediately. We look forward to starting up and inspecting your system in the Spring! Don’t forget to renew your annual membership, if you haven’t already! Any necessary repairs or upgrades were identified and recommendations provided. Zone valve closest to the right of the manifold in front of the poly on the backflow has no bleeder. None of the zones were turning on from the controller so I manually winterized the system from the solenoids. The controller is most likely broken. Return trip to fix the customers controller was sent to the customers email.
