Replaced broken and leaking backflow preventer internal bonnet and poppet. Retested good. Ran all zones temporarily to melt any ice that might be in system. 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. Recommended WiFi smart controller upgrade.
