Howdy all,
I recently bought and set up a CO2 system, and I've got a couple of
questions about it.

1. The directions say to clean the dispensing line 'often', how ever
'often' is a pretty relative term. Should it be cleaned once a week?
Once a month? When ever the keg is changed?

2. About how long should my 10lb tank last? (I realize there's a lot
of factors involved) My fridge is at 40 degrees, my low side pressure
is set to 7-8 PSI, and I only draw about 6-10 pints a week.

3. Do people typically leave the tank open and system pressurized? Or
do you close the tank/check valve when you won't be dispensing for a
couple of days.

I'm asking the second two questions because after about 3 weeks, my
tank is empty and it doesn't seem like I've used it that much. A
quick search through old posts leads me to believe that I need to re-
check all my connections and seals for leaks.

Thanks.
