Hey HBT,

I have replaced my gas lines (2x) over the 2 years I have been kegging. Never noticed any beer back flow, as I never connect the gas to a pressurized keg or change the pressure other then higher on the regulator side while connected to a keg.

I have noticed on all my beer lines I get these white residue marks. Is this from the C02 gas leaving marks on the tubing? Anyone else see anything similar with their setup? Never noticed issues or infections with my beers once they are in the keg serving.
