We don't like how flat the pressure has been at the corner station since being combined with the arms following the post O2 in-chamber de-install/install activities.  As such, I confirmed that the Vent/Purge valves were fully closed.  Today, the NEG1, NEG2 and NEG3 pumps were individually valved-out for 25 minutes or so each.  The responses are attached.  Next, we would like to verify that the 1 1/2" AMV pump port valves located atop the 2500 L/s ion pumps are fully closed and maybe repeat today's exercise with the 2500 L/s ion pump isolation valves.
