    Default RO storage

    I ran preservative through my ro. Should I drain it or just let it be like it is.

    Don't drain it, you don't want to let the membrane dry out.

    What kind of preservative are you using for storing in the machine? Thanks.

    I don't know what KReinisch uses but I use Leader's membrane preservative. I just close the needle valves to hold it in the membranes, and I rinse out the wash tank. Then keep the RO from freezing.
    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.

    It's generally a 1 weight % solution of sodium metabisulfite in water.

    I use a solution that calls for 1 cup of solutions for 5 gallons of water. So I mixed up 10 gallons and let it circulate through the ro for a bit.
