Anybody ever had any problems with using second hand IBC's?. I bought my first one new because I worried about what might have been in one previously might affect the purity of the stored water.
I need a second one now, and if I can manage with a used one it will save me quite a bit, but I need to be sure because I'll be connecting the two up in tandem so could contiminate the first one.
Cheers,
Ian
