To get the acid wash in the membranes just recirculate. Then shut the pump off and immediately close both needle valves. Then drain and rinse the tank, do not leave the acid in the tank. Do you have an owner's manual from me? If yes and it tells you not to leave the acid in the wash tank, follow it, if you have an older version send an email to: dave@cnymaple.com and ask for a manual. I made some corrections in the last 4-6 weeks to help clarify some issues. Anyone who has a Deer Run RO (Ray Gingerich), send for my manual, it will help.

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.
