Any corrosive exposure? I just looked at a building where hydrochloric acid vapors melted out a link.

I have also queried if any re-roofing had occurred on the very unlikely scenario the heat may have transferred below.

Or temperature spikes from some special cause (paint stripping with heat gun etc.)?

On inspection of the others following a drain down we found several others without the link in place. We can only assume that this happened once the pressure was removed. Has anyone experience of this happening and reasons why? We can rule out heat, pressure surges and works in the areas. The two heads that activated were in different areas of the system.
