One topic of debate was what to do with the units between dives.
Previously I've always popped the exhale hose off and drained out the lung butter then left it sealed. The Inspo diver was getting regular cell warnings on No.2 despite proper storage of the unit, it was suggested that he leave the loop open (breathing hoses disconnected from T-pieces) to "dry it out" this seemed to help and the warnings went away.
Between dives the units got dried out properly but not disassembled.

Hello Ben, I have drain stems on the bottom of my CLs, very similar to the kind on a safety sausage. Inbetween dives I inflate the loop with my mouth, keeping pressure up to where the OPV is about to blow and I open the drains and out comes whatever water there is. Almost always there is more in the exhale CL and if there is a lot in the inhale CL, I know the loop is leaky. My scrubber bucket is transparent plastic so I can also see if there's an unusuall amount of water in the bottom, as well as being able to check the scrubber seals themselves. This all very helpful and time saving as I can easily tell if everything is normal without disassembly.
At the end of the day, I pull off the scrubber bucket and let the sensors and loop dry out some more, before sealing/bagging up the unused scrubber cartridge for the night and loosely fitting the bucket back on so as not to allow any critters inside the loop.
That's my routine and I don't have to disinfect, disassemble the unit or do neg/pos tests more than once a week, and I do all my diving in the tropics. No moisture related performance problems or illness yet in 9 years. -Andy
