Beer in lines going flat

[elpenoso]

Im not sure why but the beer in my lines go flat after a few days. There must be a leak righhhht?

If the beer in the keg is carbonated and the beer in the lines is flat, then you have a tap leak.

Seems to me if there was an outright leak of some kind you'd either have a puddle of beer or an empty CO2 tank.

So, what kind of beer lines are being used? Straight vinyl, or barrier-lined? I'm not certain that straight vinyl is permeable, but I use barrier-lined and don't ever recall the first couple of ounces of beer being flat...

Cheers!

Ball lock connectors have a spring and valve within which can retain pressure when the tap leaks. Try over pressuring a keg and turn the gas pressure down and you will see this in action on the gas side.

Huh, still don't understand what you mean.

I have vinyl beverage lines with cobra pick nick taps.
