Draft System Maintenance - Close valves?

[TGTimm]

When you shut down on Sat night, reduce the keg reg to your eq. pressure for your cooler temp, and then release the pressure in the keg. There's a check-valve in the coupler that prevents CO2 (an beer) from flowing back to the reg, so just turning that down won't prevent over-carbing. If your push pressure is more than about 2 psi higher than the eq, think about using mixed gas.

What is the carbonation level of your beer? What CO2 pressure are you using?

With the beer sitting for three days without use, and probably longer before the keg is empty, any CO2 pressure above the equilibrium pressure for you carb level and temperature will result in the beer eventually being over-carbonated. You can reduce the partial pressure of CO2 by using a nitro-mix.

Our first few batches had somewhat wonky carb levels as we learned the system. So we're having to mess with the individual line pressures for decent pours right now. We've pretty much got a handle on carb levels now and will try to keep everything at 2.7 volumes going forward and will set the pressure in the keg cooler to maintain equilibrium.

Our tap room just opened and we are currently running a Wed. - Sat. schedule (closed Sun, Mon, Tue).
I'm wondering if we should be closing valves on our tap system when we're closed for several days (or even overnight from one day to the next?)

Our system is a single 50# co2 bottle feeding a 4-channel manifold (each channel has a shut-off valve).
Each manifold channels feeds two taplines - each with it's own regulator and shut-off valve.

So I have a number of places where I could close things up if need-be.

Any recommendations on best practices for times the taproom is closed?
