Ok, I'm Chilled. I'm Chilled. Relax....56K Warning!

You can't be serious. Have you never seen the inside of hot water heater? I don't have anything to prove. The statements I have made are accepted as fact by the scientific community at large and have been proven time and time again to be correct. Troll me if you must, but you are the one with the radical idea that tap water is acceptable.
You also can't presume to know the water quality of everyone, even in the state in which you live, much less the entire planet. You seem to be not understanding the consequences for others if they attempt to use tap water and don't go to your house to get it. Your personal experience is limited to the water that comes from your tap alone! If you can't accept the fact that your being callus and irresponsible by telling everyone that tap water is OK for their cooling loops even though you have no idea what is in the water that flows from their tap, then this discussion is finished. You may continue to ramble on and try to play childish games with me but I will not respond. I don't argue with children.

Like I said before, more than once, use whatever swill you wish, but certainly don't recommend that it is safe for others to do so. In the end it is your investment and your hard work.

But my only one real point is: I don't recommend that people use tap water in their blocks---I simply state that I use tap water in my blocks. Even on that 1 simple point you can't get it right.

Except in the post I originally quoted where you did actually suggest that antiacid use tap water for auto leveling without taking into consideration that not everyone's water is the same as yours.

I'll quote it again considering that is what the issue is all about.

The amount of water evaporated is going to be effected by many different things like: water temp v. ambient temp, relative humidity and so on. If you put your pump as low as possible in the res it will offer more headway against evaporation. Hooking up to the plumbing for a sink, shower, toilet, washer, etc is not difficult to do. One small hole through a wall can be all that's really needed to run a line of 1/4" ID ice maker tubing to a float valve. Odds are you have incoming water in the next room....there's the source. Holes through drywall are easily fixed.

There are ways to setup a 2-liter bottle, gallon jug, 5gal bucket for short-term auto-refill.....
