Turn off Co2 while on vacation?

[JOHN51277]

I don't really see any need to, but should I do anything while I am on vacation with my kegging system? It is set at 12psi. Maybe my inlaws will pull a few pints off while watching the house.

If it's going to be used then no. If you do turn it off I'd make sure to disconnect the lines from the keg(s).
