Wether it’s a conspiracy or not remains to be seen – but after putting some leak sealer in the system, the leak stopped.

Then it started.  Slowly going down.

Then it reached a stage where it would hold all week, then drop 0.5 bar in pressure suddenly.

Bottom line is now it’s held pressure for 10 days.  That would indicate no leak?!?!?!

I’m not counting my chickens yet though…
