I've been told that in NY you didn't need to grade it under the old system, but if you did (I never saw much ungraded) it had to be correct. Using the new system I don't know if that is an option, but in NY we can not use the old grades after 1/1/15. I have no idea what Pa. regs are.
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.
