Answers to the most common questions about water quality, treatment systems, maintenance, and our services.
Is Tennessee Municipal Water Safe to Drink?
Safe drinking water can still have issues inside your home.
Tennessee municipal water is treated to meet drinking water standards, but that does not always mean it tastes, feels, or performs the way homeowners want it to. Many homes still deal with chlorine, chloramine, hardness minerals, sediment, and dissolved solids that can affect water taste, appliance performance, plumbing longevity, and everyday comfort. A free water test helps show what is actually in your home's water so Pure H2O Water Systems can recommend the right solution with confidence.
Taste & Odor
Chlorine and chloramine can affect how your water smells and tastes.
Appliance Protection
Hardness minerals and scale can impact water heaters, dishwashers, and fixtures.
Plumbing Longevity
Sediment and buildup can create unnecessary wear on your home's plumbing.
Everyday Comfort
Water quality can affect skin, hair, laundry, cleaning, and daily use.
No guesswork. Just real answers about your home's water.
What Does Hard Water Look and Feel Like?
From the moment water enters your home, its quality affects everything it touches: your family's health, your appliances, and even your monthly bills.
One system. Whole-home protection.
The right water treatment solution addresses all of these areas.
Every Drop Counts
The average family of four uses over 300 gallons of water every day. That water flows through your pipes, your appliances, and into your body. When your water carries dissolved minerals, chlorine, or other contaminants, those issues multiply across every use.
Treating your water is not just about better taste. It is about protecting the thousands of dollars you have invested in your home's plumbing, appliances, and fixtures.
Drinking & Cooking
Chlorine, sediment, and dissolved solids affect taste and safety of everything you consume.
Bathing & Showering
Hard water minerals and chlorine strip natural oils, causing dry skin and brittle hair.
Laundry & Cleaning
Hard water fades colors, stiffens fabrics, and requires more detergent to get clothes clean.
Appliances & Plumbing
Scale buildup silently damages water heaters, dishwashers, washing machines, and pipes.
Does Hard Water Affect My Home's Efficiency?
Hard water silently damages your water heater from the inside. See how soft water protects your appliance and your wallet.
Annual Impact of Hard Water
The Soft Water Advantage
Scale is a major cause of inefficiency.
Just 1/8 inch of scale buildup can reduce efficiency by up to 12%.
Hard Water
Mineral buildup reduces performance
Scale Buildup
Minerals like calcium and magnesium build up inside the tank and on the heating elements.
Reduced Efficiency
Scale acts as an insulator, making your water heater work harder and use more energy to heat water.
Higher Energy Costs
More energy used equals higher utility bills every month.
Shorter Lifespan
Scale buildup causes extra wear and tear, leading to more repairs and a shorter water heater life.
Soft Water
Improves efficiency and extends life
No Scale Buildup
Soft water prevents minerals from sticking to the inside of your tank and heating elements.
Maximum Efficiency
Your water heater heats water faster and uses less energy to do the job.
Lower Energy Bills
Uses less energy, saving you money every month on utility costs.
Longer Lifespan
No scale means less strain on your system and a longer-lasting water heater.

Everything you need to know about water treatment, from what is in your tap to how the right system saves you money.
Water Quality
Tennessee's municipal water systems provide safe drinking water, but many homeowners experience issues related to chlorine, chloramine, hardness minerals, sediment, and dissolved solids. These conditions can affect water taste, appliance performance, plumbing longevity, and overall comfort.
Common causes include chlorine, chloramine, sulfur compounds, organic matter, and high mineral content. Chlorine and chloramine are used by utilities for disinfection and can leave a noticeable chemical taste or smell. If your water has a metallic taste, it may contain iron or manganese.
White spots are usually caused by hard water minerals, specifically calcium and magnesium. When water evaporates, these minerals are left behind as residue. A water softener removes these minerals, eliminating spots and making dishes sparkle without hand-drying.
Dry skin after showering is often caused by chlorine and hard water. Chlorine strips natural oils from skin and hair, while hard water minerals prevent soap from fully lathering and rinsing clean. Many homeowners notice softer skin within days of installing a water softener or filtration system.
Water Softeners
A water softener removes calcium and magnesium through a process called ion exchange. Benefits include softer water, reduced scale buildup, longer appliance life, and better soap performance. You'll use less soap, shampoo, and detergent while getting better results.
For most Tennessee homeowners: yes. Much of Tennessee has moderately hard to very hard water. Common signs you need a softener include scale buildup on fixtures, water heater inefficiency, spotting on dishes, reduced appliance life, and increased soap consumption. Most municipal water in Knoxville and the surrounding areas of East Tennessee falls into the moderately hard to hard range.
For a family of four with a Puronics system, a reasonable expectation is approximately 80-160 lbs of salt per year, or 2-4 forty-pound bags annually. The iGen controller helps optimize regeneration cycles, which can reduce salt consumption compared to older timer-based systems. Usage depends on family size, water hardness, and water usage.
Typical water softeners last 15-20 years. Premium systems like Puronics can last 20+ years with proper maintenance. Using quality salt, keeping the brine tank clean, and having the system professionally serviced are key to maximizing lifespan.
Filtration & Reverse Osmosis
A water softener removes hardness minerals using ion exchange. A water filter removes chlorine, chloramine, sediment, taste, and odor using various filtration media. Most homeowners need both: a softener for whole-house hardness removal plus targeted filtration for drinking water quality.
Reverse osmosis is recommended for drinking water and cooking water. It removes a broader range of contaminants than standard filtration, including dissolved solids, heavy metals, and certain chemicals. RO is not typically necessary for whole-house use. It is best for point-of-use drinking water.
Yes. A properly designed carbon filtration system can reduce chlorine, chloramine, taste, and odor throughout your entire home. This means better-smelling water from every tap, reduced chlorine exposure during showers, and better-tasting drinking water.
Certain advanced carbon and reverse osmosis systems can reduce PFAS, also called Forever Chemicals. These are persistent environmental contaminants from industrial activity, manufacturing, and firefighting foam. If PFAS is a concern for your area, we can recommend a system specifically designed to address them.
Cost & Value
Many homeowners save money through lower soap usage, reduced plumbing repairs, longer appliance life, and better energy efficiency. Protecting your water heater, dishwasher, washing machine, and plumbing from hard water damage can save thousands in replacement and repair costs over time.
Indirectly, yes. Benefits include protected plumbing, protected appliances, and being an attractive feature for buyers. A whole-house water treatment system signals to potential buyers that the home has been well-maintained and that they won't face hard water issues.
Installation
Most installations take 3-6 hours and are usually completed in one day. Our team arrives on time, protects your floors, completes the installation cleanly, tests the system, and cleans up before leaving.
Typically, there is only 30-60 minutes of water interruption during installation. We plan the work to minimize inconvenience and will let you know exactly when the water will be shut off.
Common locations include the garage, basement, mechanical room, or crawlspace entry. We evaluate your home's plumbing layout and recommend the optimal location that provides easy access for maintenance while staying out of the way.
