Dallas water tests between 7.5 and 8.6 grains per gallon of mineral hardness. This mineral content precipitates as solid calcium scale inside the tank, shortening typical tank lifespan to 8–10 years. We recommend annual flushes and anode rod checks to preserve tank longevity.

Full replacement of a 40 or 50-gallon tank—including new safety pan, thermal expansion tank, brass shutoff, Dallas city permit, and haul-away—generally ranges from $1,400 to $2,300 depending on whether it is located in a closet, garage, or attic.

Yes! Moving a water heater out of a hallway closet and installing an exterior wall-mounted tankless unit is one of the most effective home upgrades in East Dallas. It eliminates interior leak risks and frees up valuable closet storage.

Dallas Water Utilities has been installing new water meters equipped with internal check valves. This creates a closed plumbing system. When water in your water heater heats up, it expands. Without a thermal expansion tank, that pressure has nowhere to go and forces open your temperature and pressure relief valve. We install calibrated expansion tanks to solve this permanently.
