I recommend that you vent the water and change the after pump drier filter every new start-up. Rotate them with another filter drier and vacuum bake them out under full vacuum and 250F in the interim.
I'm not a fan of "recoverous interruptus", both because of the lost butane and open containers exposure to atmosphere.
Yes, pumping oxygen containing atmosphere into your storage tank is unsafe. You might minimize that by warming the butane up enough to build pressure, and then burping away the atmosphere before attempting to recover it with the pump.
Burp your tank afterwards, to vent any you missed.
A 3 X 36" spool has an internal capacity of around 233 cubic inches, which holds about 5 lbs of butane.
