Water softeners & filtration in Nashville

Nashville is softer than Rutherford County but treated with chloramine, which is the reason so many Nashville homes taste chlorine long after the pitcher has been sitting out.

Nashville is supplied by Metro Water Services, drawing from Cumberland River — Omohundro and K.R. Harrington treatment plants.

What’s actually in Nashville water

Nashville homes are on Metro Water Services, which draws from Cumberland River — Omohundro and K.R. Harrington treatment plants. Like nearly all of Middle Tennessee, 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

Nashville water questions

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

Where does Nashville's water come from?

Nashville is supplied by Metro Water Services, drawing from Cumberland River — Omohundro and K.R. Harrington treatment plants. 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 Nashville?

Most Nashville 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 Nashville?

It depends on your water hardness, the size of your home and where the equipment can go — so we do not publish one figure we would then have to walk back. What we will say is that we sell the same class of equipment the national brands do for roughly half what they charge, and the free in-home test turns that into an exact number for your house before you decide anything.

How long does installation take in Nashville?

A whole-home system is usually a half day. An under-sink reverse osmosis system is around two hours. We clean up before we leave, and the price you agreed is the price at the end.
