Default Shut off Co2 when not in use?

I force carbonated my first ever keg at 30 psi for 2 days then purged and dropped down to 10 and serve. It taste's great, but just wondering if I only have a couple glasses of beer a day should I be using the shutoff valve on the regulator to cut off the CO2 from the keg so it doesn't over carbonate?

No, just leave it set to desired psi and leave it open. As you draw beer, you'll create a little more head space that needs to be filled. That's how it is designed to work.

If you shut it off, your psi will drop as you take beer. You want it to stay the same.

you can't over carbonate if you leave it on, as long as you abide by the table here

if your regulator is set to the volumes you want, based on the chart, the beer will reach equilibrium.

Not to turn this into a force carbonation discussion, but the only time i've ever overcarbed my beer is when I set it real high at 30 for a few days. Now all I do is set at serving pressure and leave over night, then shake it around the next day at the same psi. Perfect every time and no matter how much you shake that thing it won't go over serving pressure.

Leave it on at your desired serving psi - mine's usually around 8-10 psi.

It's more of a peace of mind thing to help prevent losing CO2 due to leaks. As long as you abide by the table mentioned above you will be fine leaving it on (provided there's no leaks in your system).

I turn it off just because I don't like losing CO2 to slow leaks. I recharge my kegs once or twice daily.

Leave it on, if you have leaks fix them. It's really that simple.
