Site 853
System type: Pumped - differential controller
Installed: 1996
Inspected: 2004
System is no longer operating.
The air vent developed a constant leak and the client drained and isolated the system.
Test of the controller and sensors was conducted. Tests indicated that the controller and sensors were still in operational condition. The pump was disconnected but appeared to operate when plugged into a receptacle.
The solar collector and glazing looked good. The rear mounting brackets at the collector only had one screw (which was rusted) rather than two.
The pipe insulation was coated with some type of paint material. The material degraded and in turn the insulation itself is also starting to degrade.
