Site 476
System type: ICS
Installed: 1997
Inspected: 2003
No problems.
Valves ok. Very small aqua colored spots on tube and end caps in area of end caps. Appears to be some type of residue from the brazing process? In any event, they do not appear to be getting larger and causing corrosive wear. Insulation is satisfactory. The usual – tape that holds the insulation is deteriorating somewhat.
Auxiliary tank is in elevated position and system valves are above the tank. Very hard to get to and have to use mirror to determine orientation of valves.
