Water Cooler Bottles...?

[Dillbag]

I'm sure this has been adressed before... But, I didn't find anything.

Has anyone used or does anyone know if it's ok to use water cooler bottles as a primary/secondary fermenter...?

The ones I have seen are all #7's and at 5 gallons seem like a great size! I looked up Better Bottles and they are PET (#1's)...

1's 2's and some would say 3's are even ok. 7's are not good.

Well crap. I use nothing but water bottles for fermenting and secondaries. I just went out and checked and they all have a "3" on the bottom. Guess I'm gonna die.
