I'll check with Ray, thanks. I'm likely going to continue to use my 250 Deer Run until I get old enough that I decide to quit, since I've cut back from 1320 taps. I did finally buy a new set of MES membranes because I detected some funky growth in my permeate tank about 2-3 mos. after the season in a tank with 4-500 gal held for other uses. That told me that even though I got a zero sugar reading in my permeate water even when concentrated to 1/10 original volume it was passing some sugar, since the permeate tank is a fully enclosed 1000 gal SS tank.
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.
