CO2 source must be disconnect when performing a seal check. Leak checks are required with all gas systems. It is advised you attach the CO2 source back to the Freedom One Hose then dip the end you 'inspected/changed the o-ring' in a cup of water. If bubbles show you may need a new o-ring.
If you have refiled your KegLand Branded Sodastream, it is avised you do a minor fill and dip in water to reveal any leaks. 

False positives: Sometimes the pin does not seat correctly after filling/use because of large amounts of ice formation. Clearing this blockage fixes most leak situations.
