Hi Mauri,

S2 is one of the better detectors "leakwise". Ambient pressure is in a 
major drop, so the differential pressure is high. There is a bubbler set 
to about 3inH20 that is protecting the sector. And of course since the 
pressure is high, no gas is flowing. See attachement. We will keep an 
eye on it.
