Just realize that 3/16 is great in year 1, but it requires more work in the following years. I have quit a bit of 3/16. After the first season it seems to help if you clean the tubing 2x, once shortly after the season and again mid to late fall. I like using 5/16 drops into the 3/16 laterals best. I also change every fitting before every season, after the second cleaning. That way there is very little debris left in the lines to flake off and create a blockage in the tees or connectors.
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.
