What’s actually in Grand Prairie water
Grand Prairie homes are on Grand Prairie Water Utilities, which draws from Tarrant Regional Water District / Dallas supply. Like nearly all of North Texas, that water arrives hard — enough calcium and magnesium dissolved in it to leave deposits on everything it touches.
You see it as spots on glassware, a white crust around faucet aerators, film on the shower door, soap that won’t lather properly, and skin that feels tight after a shower. What you don’t see is the same mineral coating the inside of your water heater, where it insulates the element and makes the heater burn more energy for less hot water.

The only way to know your number
City-wide averages tell you very little about your particular house — the age of your plumbing, your water heater and where you sit on the distribution network all matter. We test at your kitchen sink, free, and show you the result while we’re standing there.

Questions
Grand Prairie water questions
Call us if yours isn’t here — a real person answers.
Where does Grand Prairie's water come from?
Grand Prairie is supplied by Grand Prairie Water Utilities, drawing from Tarrant Regional Water District / Dallas supply. That source is what determines how hard the water is and what else is in it — which is why we test at your sink rather than guessing from the city average.
Do I need a water softener in Grand Prairie?
Most Grand Prairie homes benefit from one, but "most" isn't "all" and we won't pretend otherwise. The honest answer comes from testing your water. If it comes back soft enough that a system wouldn't pay for itself, we'll tell you that.
How much does a water softener cost in Grand Prairie?
It depends on your water hardness, the size of your home and where the equipment can go. Our Complete Home System Package has a published original price of $4,599 and we run discounts against it. Installation is free and the system carries a lifetime warranty.
How long does installation take in Grand Prairie?
A whole-home system is usually a half day. An under-sink reverse osmosis system is around two hours. We send our own installers, not subcontractors, and we clean up before we leave.
