How hard is the water in Dallas?

We install and service water softeners, whole house filtration and drinking water systems for Dallas homes. Dallas water runs hard at about 8 to 9 grains, which is what scales a water heater and spots glassware. We measure at your tap first, then quote one price for the whole job.

How hard is Dallas water?

Most do. Dallas water runs about 8 to 9 grains per gallon, which is hard enough to scale a water heater and leave spots on glassware. Whether it earns its place depends on your household size and how much water you use, so we take a reading at your tap before recommending a capacity.

The published data

Dallas’s water, measure by measure.

Most of the metroplex is on chloramine, which ordinary carbon struggles with. Dallas isn’t. The city runs free chlorine, so a standard whole house carbon filter handles the taste and smell here without the catalytic media its neighbors need. Hardness is the other half. At 8 to 9 grains you’re over the line where scale starts costing you, so a softener earns its keep, just at a smaller capacity than a Collin County home.

From the data to your tap

What this means for your house in Dallas.

A Consumer Confidence Report describes water leaving a plant or averaged across a distribution system, not water arriving at your address. The free test closes that gap in about twenty minutes.

Do Dallas homes need a water softener?

Most do. Dallas water runs about 8 to 9 grains per gallon, which is hard enough to scale a water heater and leave spots on glassware. Whether it earns its place depends on your household size and how much water you use, so we take a reading at your tap before recommending a capacity.

What water treatment do most Dallas homes start with?

A softener for the scale, then carbon filtration if the chlorine taste bothers you. Dallas uses free chlorine rather than chloramine, which ordinary carbon handles well. Most homes here start with one system and add drinking water treatment at the kitchen tap later if they want it.

Do I need a whole house filter as well as a softener?

Not always. A softener removes the calcium and magnesium behind scale but leaves chlorine taste and smell untouched. If the shower smells like a pool or the tap tastes flat, whole house filtration is the part that fixes it. Both can go in on the same visit.

Can you treat the water in an older Dallas home?

Yes, and older plumbing is one of the more common reasons homeowners here call. Scale builds up in pipe and at the water heater over years. We check the incoming line and the space available before quoting, and a bypass goes in as standard so future service never means shutting off the whole house.

How long does installation take in Dallas?

Most whole house installs here are about half a day, with the water off for two to three hours. Older Dallas homes take a little longer to survey, because we check the condition of the incoming line and the water heater connection before cutting anything.

Do you charge for a quote in Dallas?

No. The quote is free and carries no obligation. You get one price covering equipment and installation together. Dallas water is hard enough that most homes benefit, but if your reading does not justify a system we will say so.

Where can I read Dallas’s own water report?

The source we work from is published at dallascityhall.com. That is the source for the figures on this page.
