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. No rain sensor. Old toro flo pro valves, zone left of driveway stuck open. No drain valve upstream of backflow preventer, causing trapped water. Timer in garage had a glitch, causing all odd # zones to change run times to 2 hrs 40 minutes each. Recommending WiFi smart controller. Recommending to replace backflow preventer.
