That is not a jug manufacturer type issue. You either had foam or over filled the jug, and your temp was too hot. Don't fill at over 190 and don't fill all the way to the top of the neck, filling at 184-188 is best. A full measure is just at the bottom of where the cap threads start. If you fill above that you leave no space for a vacuum to occupy and then the sides of the jug are sucked in. If you have a truly accurate scales, weigh the jug as filled and subtract the weight of an empty jug. Should be 11 lbs. If you don't have that accurate of a scale this will not work and if density is off too much it won't either.
Dave Klish, I recently ordered a 2x6 wood fired evaporator from A&A Sheet Metal which I will be converting to oil fired
Now have solar, 2x6 finish pan, 5 bank 7x7 filter press, large water jacketed bottler, and tankless water heater.
Recently bought another Gingerich RO, this one was a 125, but a second membrane was added thus is a 250, like I had.
After running a 2x3, a 2x6, 3x8 tapping from 79 taps up to 1320 all woodfired, now I'm going to a 2x6 oil fired and a 200-425 taps.
