I only use potable water hose, I never want to introduce any of the things that are in those other hoses into my equipment. Non potable water hoses can be made of any recycled materials that can contain lead or even poisons from in recycled materials.
I rarely kink a hose, you just need to develop a system when moving them to prevent kinking and take a little time to check as you pull the hose around. Also, I do not use the potable water hoses from Walmart, they are too flimsy. Find a better quality one, costlier, but from an RV dealer. The hose will be higher quality.
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.
