leaving liquid line attached, but disconnecting gas between serving?

[Unicorn_Platypus]

I've got a few beers that I want to remain carbonated at different levels. I only have a single regulator, so can't serve at multiple pressures.

for example, these are beers that were previously carbonated at below levels (using set & forget method)

1) Belgian Saison @ 16 PSI
2) Pilsner @ 12 PSI
3) Imperial Stout @ 8 PSI

Assuming these are already carbonated, can I simply disconnect the gas lines while keeping the liquid line attached between servings?

I'm currently using Accuflex Bev-Seal ultra on the liquid side (which is barrier protected). I'm also using Intertap flow control faucets.

Do you not know if these brews are carbonated?

You can disconnect the gas lines, set the regulator to the desired pressure, and serve. Lather, rinse, repeat for different kegs. You will also have a handy way to discover any slow leaks in your kegs.

I would still disconnect the liquid lines if they're going to sit still for a longer time. Besides the risk of them developing a leak there's still oxygen ingress even from the best barrier material and there's also the possibility of developing and infection that might migrate to the keg and spoil it.
Besides that nothing bad is obviously going to happen just because you disconnected the CO2 supply.

I do this all the time.
I "bump" them to pressure with CO2 and disconnect gas.
You do have to know whether your kegs will hold pressure, per @grampamark , with the full understanding that if the beer is not carbed yet and you disconnect CO2, beer might still absorb CO2 and thus reduce keg pressure accordingly.

The reason why I want to keep the liquid line attached is that I want to avoid the line running dry and remove the need to flush the lines between serving.

I've got 5 faucets and would prefer to keep a line dedicated to each beer.

Are you saying to disconnect the line and just leave the fluid in there until the next time I serve?

If the line has no leaks there should be no way it could run dry. Of course it would be best to flush and rinse every time but that's up to you.

been leaving beer in bev tubing lines 3 years with no issues.
