If using plastic taps of any design, just use new taps, don't bother sanitizing them. For the drill bit, use an official tapping bit. Then I boil them in potable water after the tapping is done, let them dry completely then seal them in a zip lock bag. Save them for next year. At 50 taps, you should be good to use that bit at that rate for several years, normally a tapping bit will be good for 2000-2500 holes. Don't use it for any other use, use a regular hardware store bit for other uses.
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.
