What's in Dublin's water.

Dublin water runs 5.7 to 7.3 grains per gallon, which the industry calls moderately hard. You see it as white scale on faucets and shower glass, a film on dishes, and shorter life for water heaters and dishwashers. Soap works harder too. A softener takes the hardness to near zero.

Columbus disinfects with chlorine, not chloramine. That is what you taste and smell at the tap. A carbon tank removes it from every faucet; the RO system handles the drinking water at the kitchen sink.
