How Hard Is Dallas Water? A Complete Guide
Hardness levels, sources, and what they mean for Dallas-Fort Worth homeowners.
Dallas tap water is moderately to very hard, typically measuring 7 to 11 grains per gallon depending on the neighborhood and time of year. Hardness comes from naturally dissolved calcium and magnesium in the lakes and reservoirs that supply North Texas.
What hard water actually does
Hard water leaves the visible stuff first: white spots on glass, soap scum, crusty buildup on faucets and shower heads. Behind the scenes it shortens the life of water heaters, dishwashers, washing machines, and tankless units, and it cuts the efficiency of your soaps and detergents.
What you can do about it
A properly sized whole-home water softener removes the calcium and magnesium that cause hardness. Paired with a whole-home carbon filter for chlorine, and a reverse osmosis system at the kitchen sink for drinking water, most Dallas homes can solve every common water complaint at once.
