During the weekend 23-24th of October, the lab and ThomX suffered a power breakdown.
All the pumping systems had to restart.
as a consequence, the pressure on Monday 25th morning was 4.3e-9 and 4.6e-9 mbar in the left and right vessels.
this morning, the Tuesday 26th, the pressure is 1.4e-9 and 3e-9 mbar.
now, these pressures are compatible with the opening of the valves!
