Any recycled plastics are never food grade because there is no way of knowing what they may have contained or come in contact with. Use only buckets or jugs that had food in them. You have 9 months to get a supply. Check at bakeries, (even the bakery dept in a Walmart or such) for buckets. In my first year I went to a Chinese Restaurant and got all of their empty 5 gal cooking oil jugs for about 4-5 weeks. I then put a hole in the cap to run the tubing in. They took 3-4 times to clean them well, then 4 good rinses, but they worked well. And they were free.
Dave Klish, I recently bought 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.
