Winterization Found Backflow internals cross threaded and had to be replaced under warranty and also the timer looks little bit bad and it could get worse. Emergency defrost charged because to get the system running took more than 30 minutes 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.
