I've tried Leader 30P and Flex, LaPierre, and D&G (flex?). In use I like the flexability of the softer tubings but I have gone to all 30P for my drops, all of which are 5/16. For my lateral line I've been using and like D&G 3/16, but I still use 30P for my 5/16 laterals and my sap ladders using the spider method.
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.
