    Thanks

    The only one I'm familiar with is 30P, I have no idea what 20P or 25P might be. I've also only noticed the 30P on Leader tubing.
    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.

    If you type in difference between 20p and 30p maple tubing into google search you will find a heading that will refer you back to mapletrader and explain the differences.
