Winter prep and system check. System is in good working condition. With the winter prep we checked the system to make sure everything was working and no major issues. After the system check we shut the water off at the ball valve before the backflow device and opened the test ports to drain the backflow. We also ran each zone to flush the water out of each valve. In the spring we will do another overall system check to make sure it’s still in good working condition for the upcoming season.
