How hard is the water in North Texas?

If you are on a private well in the Fort Worth metro, Parker County, Wise County, or anywhere drawing from the Trinity or Paluxy aquifers, your water hardness likely falls between 15 and 30+ grains per gallon (GPG). For context, anything above 10 GPG is considered very hard. Most North Texas wells blow past that number.

What does hard water actually do to your home?

Hard water is loaded with dissolved calcium and magnesium. When that water heats up or evaporates, those minerals come out of solution and form scale — the white, chalky buildup you see on faucets, showerheads, glass doors, and inside your water heater. Over time, scale:

• Clogs pipes and reduces water flow
• Coats heating elements in your water heater, forcing it to work harder and burn more energy
• Shortens the lifespan of dishwashers, washing machines, and any water-using appliance
• Leaves spots on dishes, film on shower doors, and dull, stiff laundry
• Dries out skin and hair

Hard water does not just cost you in appliance replacements — it raises your energy bills every single month because scale-coated heating elements are dramatically less efficient.

The proven solution for hard water is a water softener — an ion-exchange system that swaps calcium and magnesium ions for sodium ions as water passes through a resin bed. Legacy Water Well installs commercial-grade softeners built to handle the extreme hardness levels found in North Texas wells.

We do not install the lightweight residential units you find at big-box stores. At 15-30+ GPG, those units cannot keep up with the demand and burn through salt at an unsustainable rate. Our systems feature:

• High-capacity resin beds sized to your household water usage and hardness level
• Metered regeneration — the system only regenerates when needed, saving salt and water
• Bypass valves for easy maintenance access without shutting off water to the house
• Digital control heads with diagnostics and adjustable settings

Need a comprehensive approach that handles hardness plus iron, sediment, or bacteria? See our whole-house filtration systems for a multi-stage solution.

Some signs are obvious. Others sneak up on you over years:

• White crusty deposits around faucet aerators, showerheads, and on pot rims after boiling water
• Soap that will not lather — you use more shampoo, dish soap, and laundry detergent than you should
• Stiff, scratchy laundry even with fabric softener
• Spotty dishes and glassware straight out of the dishwasher
• Water heater rumbling or popping — scale buildup on the heating elements causes noise and inefficiency
• Dry, itchy skin and flat hair after showering

The only way to know your exact hardness level is a professional water test. We test for hardness alongside iron, pH, bacteria, and other parameters so we can recommend the right combination of treatment.

A water softener installation on a well system typically takes half a day. We install the unit after your pressure tank and any iron or sediment pre-filters — softener resin needs to be protected from iron and sediment to perform correctly and last.

After installation:

• You will notice softer water within hours — soap lathers better, skin feels smoother, laundry comes out softer
• Existing scale will gradually dissolve from pipes and fixtures over weeks
• Your water heater will run more efficiently as scale stops accumulating
• You will use significantly less soap, shampoo, and cleaning products

Ongoing maintenance is simple: keep the brine tank filled with salt (we will tell you which type and how often based on your usage) and schedule an annual inspection to check resin condition and system performance.
