Beer engine problem....or not

[redmire fc]

Hello beerdos.. afraid I haven't had the time to be more sociable, but beer brewing is such an exciting art I just want to know the answers and get on with it... anyway...When U buy beer in polypins they say drink in 3 to 4 weeks....I want to hook my knew beer engine up to one.. would submerging the poly in water prevent o2 permeability.....or not? Always with the weird questions.....

No. I'm no chemist but I'm sure there's free O2 molecules in water. SUrely you can manage a polypin in a few weeks.

Yeah...probably just get a 10 ltr poly and leave the rest in demi's....25 ltrs a month and my girlfriend will think i cant leave it alone......"you drink too much...", what! MOI?!
