Purification and warmup flow only averaged ~0.3g/s overnight so we did not warm up the entire line.
Flow was limited by flowing through a small valve at the ESR end and maybe also by contamination.

Cryo is working to make the flow path external to the transferline/DBX less restrictive. 
We will increase the flow when we can.
