Beer going flat in OUT line

I am using a 5x10mm vinyl tube for the put line and after a day the beer in the tube loses all co2 but does not taste bad. There is no beer leaking out so I.assume the co2 is getting out through the tube fabric.

After first pour and the beer from the line is purged the beer is fully carbed from the keg.

Anyone have this problem and any suggestions?

 

That depends on where the line is. If it is outside of the refrigerated space the warmer beer will not diffuse as much CO2 and it will leave solution in the line. Either find a way to cool the lines or just blow off the first couple ounces before pouring a glass.

 

I really like my ultra barrier silver beer tubing.

 

yup, proper beer line works wonders
