Tasks details from 2019:
1) Gas room: 
	- rack S1J01 supplies detector dry air to cooling bundle flushing (10 lines) and to C6F14 and CO2 cooling cabinets (4), S1J02, S1K02, S1K03
	- racks S1J02, S1K02, S1K03 supply from membrane plant to bulkhead flushing (26)
   --> one rack could be freed up by placing 13 lines in the other two	
	(rack S1K06 supplies from membrane plant to Tracker cold volumes)	

2) in X0:
	- detector dry air from gas room to cooling cabinets runs through X0; 
   --> plan to increase flushing capacity by adding unused pipes in X0 -- although, flow can be increased elsewhere
	- flushing pixel/strips are supplied by 4 pipes from gas room to X0 racks; 
   --> pixel could be separated from strips by adding one unused pipe in X0 -- although, pixel can get dry after closing sufficiently fast

3) displace PV1 valve normally cutting off S1K06 from membrane plant to also cut off S1K07 -- suggested by Erik

4) GC: main issues are flagged as not being able to ship data to DB and have online measurement, and limited manpower -- no progress since last time

5) Sniffer rack integration into DT supervision system
