FAQs
What contaminants can a whole-house filtration system remove from Maryville’s water supply?
A properly sized whole-house system can capture sediment, rust, sand, and silt that enter through older distribution lines; reduce chlorine, chloramines, and disinfection by-products that the City of Maryville Water & Sewer Department adds for sanitation; and lower levels of common heavy metals such as lead and mercury. When paired with optional catalytic carbon or KDF media, the unit can also mitigate agricultural pesticides and volatile organic compounds (VOCs) often detected in East Tennessee ground water.
Where is the system installed, and will it reduce my home’s water pressure?
The filtration housing is plumbed into the main water line just after the municipal shut-off valve—usually in a basement, crawl space, or utility room—so every tap, shower, and appliance receives treated water. A licensed plumber sizes the filter and piping to match your service line (¾″ or 1″ for most Maryville homes). When installed correctly with a low-restriction bypass valve, the impact on pressure is minimal—typically a 2–5 psi drop that most users never notice.
How often do the filters or media need to be replaced?
Sediment cartridges generally last 6–12 months, while carbon or KDF media tanks can last 3–5 years depending on local water usage (average Maryville household: 3–4 people, ~75 gallons per person daily) and chlorine levels. Our plumbers test incoming water at installation and during annual service visits to determine the optimal replacement schedule, preventing unnecessary costs and ensuring peak performance.
Will the system soften my hard water, or do I need a separate softener?
Maryville’s water hardness averages 4–5 grains per gallon—classified as moderately hard. Standard whole-house filters do not remove calcium and magnesium ions that cause scale. If you are concerned about spotting on fixtures or reduced appliance efficiency, we recommend adding a salt-based softener or a salt-free scale inhibitor downstream of the filtration unit. The filter protects the softener’s resin bed from sediment and chlorine, extending its life.
How is a whole-house filter different from an under-sink or pitcher filter?
Point-of-use devices treat water at a single faucet, so showers, laundry, and dishwashers still receive unfiltered water. Whole-house filtration treats every water line in real time, protecting plumbing, improving indoor air quality by reducing chlorine vapors in hot showers, and providing consistent taste and odor improvement throughout the home. It is a set-and-forget solution requiring fewer cartridge changes than multiple point-of-use filters scattered around the house.
What is the typical cost and return on investment for a whole-house system in Maryville?
Installed prices range from $1,200 to $3,000 depending on flow rate, media type, and whether you add UV disinfection or softening. Ongoing maintenance averages $100–$200 per year. Homeowners often recoup the investment via longer appliance life (water heaters, washing machines, and coffee makers last 20–30% longer in filtered water), reduced soap and detergent use, and fewer plumbing repairs caused by sediment buildup. Families who currently buy bottled water can save an additional $300–$600 annually.
