System not working.

System is no longer working. Developed a leak on the roof about 1 year ago.

Conducted inspection of the tank area components. Controller was still plugged in. On auto setting. Collector loop isolation valves were closed. (Isolated collector loop.) Opened valves and soon saw water coming from the roof. Investigated at roof and discovered that someone had cut the collector feed line at the roof and capped it off. Used a plastic cap that had cracked. This was the reason water was coming off the roof during the inspection.
