keyword=BB MWDC gas system pressures retuned
Ethane/Argon mix pressure was found to be set very low on the regulator up in the gas shed. No one is sure why/when that happened.
I closed the regulator on the BB stack, Jack opened the regulator on in the gas shed and pressurized the system to 12--15psi. After waiting 5 minutes I reopened the regulator on BB to ~1.8psi and adjusted the flowmeters on the chambers to the correct settings.
All chambers are bubbling though again at a good rate. We'll see if the system is now stable.
