System not working.

Freeze valve failed about six months ago. Side of valve appears to have leaked – as well as through normal orifice. Client tried fixing freeze valve leak with JB Weld but this did not work. He isolated the system. Collector does not appear to have any leaks.
Valve leak caused stain and possible damage to roof area.
