Our solutions address contaminants like chlorine, hardness minerals, bacteria, and total dissolved solids (TDS), ensuring your water is clean and safe throughout your home.
WHY NASHVILLE HOMES NEED WATER FILTRATION
You use your water every day—for drinking, cooking, bathing, and more. But is it really as clean as it looks? The truth is, most homes across Middle Tennessee have water that contains contaminants that could be affecting your health and accelerating failure in plumbing, fixtures, and appliances like hot water heater, dishwasher, and more.
Here are just a few of the common contaminants found in city and well water:
Chlorine (Cl₂)
1.5 mg/L
| Chlorine is used to disinfect water but can leave behind byproducts that may affect your health over time.
Lead (Pb)
0.015 mg/L (EPA Action Level)
| Lead can seep into drinking water from corroding pipes, posing serious health risks, especially for children and pregnant women.
Bacteria and Viruses
Potential Presence
| Microorganisms can be present in untreated well water, leading to potential illnesses.
Nitrates (NO₃)
10 mg/L (EPA Maximum Contaminant Level)
| High levels of nitrates from agricultural runoff can cause serious health problems, particularly in infants.
Iron (Fe)
0.3 mg/L
| While not harmful in small quantities, iron can cause staining on plumbing fixtures and affect the taste of your water.
Arsenic (As)
0.01 mg/L (EPA Maximum Contaminant Level)
| May be found in trace levels due to natural deposits or agricultural runoff. Monitoring levels over time is important for maintaining water quality.
THE REAL IMPACT OF HARD WATER IN NASHVILLE HOMES
Hard water isn’t just a minor nuisance — it’s a silent destroyer of plumbing, appliances, and even your skin. In Nashville, most homes have moderately to extremely hard water, which leads to buildup, breakdowns, and unexpected repair costs.
Limescale Buildup in Pipes
Mineral-heavy water leaves behind thick, crusty limescale deposits that restrict flow and kill efficiency. Over time, this buildup can corrode plumbing and shorten your water heater’s lifespan — costing you hundreds in repairs or replacements.
Dry, Itchy Skin & Hair Irritation
Hard water and chlorine strip away natural oils, leaving your skin irritated and your hair dull and brittle. If you suffer from eczema or psoriasis, untreated tap water can make flare-ups more frequent and severe.
Appliance Damage from Mineral Deposits
Hard minerals clog and coat the inside of dishwashers, washing machines, coffee makers, and more. This silent damage reduces performance and leads to premature breakdowns — all thanks to the water running through them.
Chlorine Taste, Smell & Exposure
If your water smells like a swimming pool, that’s chlorine — and it’s doing more than affecting taste. Chlorine can dry out your skin, damage plumbing over time, and produce chemical byproducts that raise health concerns with long-term exposure.

HOW WE TEST YOUR WATER
| Our Process
You might think your water’s “filtered” just because it runs through the fridge — but the tests say otherwise.
During our free in-home water analysis, we run a series of simple chemical checks right in front of you. This includes testing for:
• Hardness minerals like calcium and magnesium
• Chlorine levels from municipal treatment
• TDS (Total Dissolved Solids) and contaminants that affect taste, health, and plumbing
As you’ll see in the photos, even water from a built-in fridge filter can fail the test. That’s because most fridge and pitcher filters only reduce taste and odor — they don’t remove the actual contaminants doing the damage.
It takes about 15 minutes, no pressure, and zero obligation — just real data about what’s in your water.

—while protecting your health & saving you on plumbing & appliances in the process.
What we always tell customers is simple:
You’ll save more by switching from hard water to soft than what the system ever costs you.
Hard water quietly drains your wallet with early appliance breakdowns, higher energy bills, ruined water heaters, and sky-high soap and detergent use. Our American-made Westinghouse system flips that equation — giving you better water, better protection, and a better return on day one.

Just because your water looks clear doesn’t mean it’s clean. Nashville’s tap water meets legal requirements, but that bar is low—and doesn’t always reflect what’s truly healthy.
According to the Environmental Working Group (EWG), Nashville’s public water supply contains 7 different contaminants that exceed their health-based guidelines, with a total 0f 11 contaminants found combined.
A few that stand out:
Bromodichloromethane – 27x higher than recommended
Haloacetic acids (HAA9) – 565x higher than the safe guideline
Total trihalomethanes (TTHMs) – 182x the suggested limit
Chloroform – 11x over the health guideline
Nitrate– 2.9x the advised threshold
These aren’t things you can filter out with a fridge dispenser or pitcher. And boiling won’t help either. The only way to know what’s in your home’s water—and how to fix it—is with a direct in-home water test.
We offer free professional water testing in Smyrna so you can see what your family is actually drinking, washing, and bathing in—and what can be done to improve it.
Most homeowners don’t realize there’s a problem—not because the water is clean, but because they’ve never taken a closer look.
Just because it’s clear and doesn’t smell doesn’t mean it’s safe or healthy. Hard water, chlorine, and other contaminants are common in Middle Tennessee, and they often go unchecked for years.
Some people do notice the signs: dry skin, cloudy glassware, limescale, or appliances that keep breaking down. But even if you’re not seeing those things, your water could still be quietly damaging your plumbing, shortening your water heater’s life, or drying out your skin every day.
A water softener removes hardness minerals to protect plumbing and appliances, while a whole-home filtration system targets contaminants like chlorine, iron, and sediment. Our Westinghouse system combines both — softening and filtering your entire water supply from a single unit.
Yes — and often more than you’d think. Hard water causes appliance breakdowns, clogs your water heater, and wastes soap, detergent, and energy. Most of our customers save more in repairs and efficiency than what their system costs to install.
Our Westinghouse-certified systems are American-made and built to last up to 20 years. Each component is backed by a lifetime warranty, and with minimal upkeep, they quietly protect your home day in and day out.
Every customer tends to notice the change immediately — cleaner tasting water, softer skin and hair, less soap needed, and spotless dishes. Your shower, laundry, and coffee all level up.
Our systems are designed to be low-maintenance, but like anything that protects your home 24/7, a little upkeep goes a long way.
Here’s what typical water softener maintenance looks like:
• Refilling the brine tank – This means adding a bag of salt about every 4–6 weeks, depending on your home’s water usage and system size. You can buy water softener salt at Lowe’s or Home Depot for around $8 a bag.
And to clear up a common myth — the salt doesn’t end up in your water. It’s used in the regeneration process to clean the internal resin that removes hard minerals from your water.
Also worth noting: systems marketed as “salt-free softeners” don’t actually soften the water. They condition it — meaning they try to alter mineral behavior — but they don’t remove hardness minerals. For true soft water, salt-based ion exchange systems like ours are the real deal.
Our Westinghouse systems are American-made and built to last, and every single component is backed by a lifetime warranty.
Yes! We serve homeowners across Rutherford County and the greater Middle Tennessee region. If you’re within 60 miles of Nashville, we can likely get to you. Just reach out to confirm your location.
There’s no one-size-fits-all price, because every home and water source is different. We start with a free in-home water test to see exactly what your water needs — then build a system around that.
What we can tell you is this: for most homeowners in Middle Tennessee, the cost of doing nothing ends up being higher.
For those who finance a whole-home system, which we provide for you, you’re looking at a monthly payment—but here’s the catch: most customers end up saving that same amount (often saving more) on everyday household expenses. Think: soaps, detergents, shampoos, appliance repairs, water heater energy use, and even bottled water and fridge filters.
So instead of adding a new bill, you’re replacing hidden costs with a system that actually solves the problem.
You’re not spending more—you’re spending smarter.
Plus, our systems are:
• American-made
• Backed by a lifetime warranty on every component
• Built to last longer than anything else on the market
We also offer incentives to help offset the investment and make clean, soft water a no-brainer.
