What’s actually in Prosper water

Prosper homes are on Town of Prosper, which draws from North Texas Municipal Water District and Upper Trinity 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

Prosper water questions

Call us if yours isn’t here — a real person answers.

Where does Prosper's water come from?

Prosper is supplied by Town of Prosper, drawing from North Texas Municipal Water District and Upper Trinity 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 Prosper?

Most Prosper 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 Prosper?

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 Prosper?

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.
