FAQs
What does a whole-house carbon filtration system do, and how is it different from a point-of-use filter?
A whole-house carbon system is installed on the main water line where it enters your Knoxville home. Every gallon of water—whether going to the kitchen sink, shower, laundry, or outdoor spigots—passes through a bed of activated carbon. The carbon’s microscopic pores adsorb chlorine, chloramines, volatile organic compounds (VOCs), pesticides, and unpleasant tastes or odors. A point-of-use filter (e.g., pitcher or faucet cartridge) treats only the water at one fixture and typically has a small carbon element that clogs quickly. A whole-house unit delivers high flow rates (10–15 gpm) and long media life (3–5 years) while protecting every tap and extending the life of appliances.
Why are carbon systems especially beneficial for Knoxville’s municipal water?
Knoxville’s drinking water meets federal safety standards, but it is disinfected with chlorine and may contain chloramine byproducts, trace pharmaceuticals, and agricultural runoff from the Tennessee River watershed. These compounds can create an off-taste and odor and may aggravate sensitive skin. Activated carbon excels at removing chlorine/chloramine and adsorbing many synthetic chemicals, giving you better-tasting water, reducing skin and eye irritation, and lowering your exposure to potential contaminants that regulations do not yet address.
How is a whole-house carbon system installed, and will I lose water pressure?
Our licensed Knoxville plumbers place the filtration tank on the home’s main incoming line—usually in the basement, crawl space, or garage—just after the shut-off valve. The tank is sized to match your home’s flow demand; most 1–3-bathroom houses use a 1.5-cu-ft carbon unit with a 1-inch port, ensuring minimal friction loss (only 2–3 psi at 10 gpm). After a brief plumbing tie-in and a 10-minute carbon rinse, we restore service. You should not notice any drop in water pressure or change in hot-water recovery time.
What routine maintenance does the system require?
Unlike cartridge filters that need monthly changes, a whole-house carbon bed is backwashed automatically by a digital control valve. The valve flushes the media 1–2 times per week, lifting and redistributing the granules to prevent channeling. This backwash cycle uses about 40–50 gallons of water—roughly the amount of one load of laundry—and discharges to a nearby floor drain. Aside from checking the valve battery and verifying the date/time after power outages, the only maintenance is replacing the carbon media every 3–5 years, depending on usage and chlorine levels.
How long does the carbon media last, and what signs tell me it’s time to replace it?
For an average Knoxville family of four (about 300 gallons of water per day at 1 ppm chlorine), a 1.5-cu-ft GAC bed lasts 750,000–1,000,000 gallons—or roughly 3–4 years. If your household is larger or your incoming chlorine is higher, life expectancy shortens. Indicators that the media is exhausted include the return of chlorine smell or taste, increased turbidity, or verified chlorine breakthrough on a test strip. We recommend annual water testing; when free chlorine is detected after the filter, schedule a media changeout.
What is the typical cost of a whole-house carbon system in Knoxville, and are there rebates or warranties?
Installed pricing ranges from $1,350 to $2,100, depending on tank size, control valve features (metered vs. timed backwash), and site conditions (crawl space vs. basement). The price includes the first fill of high-grade NSF-certified granular activated carbon, plumbing labor, and a bypass valve for easy service. Our systems come with a 10-year tank warranty and 5-year valve warranty. Knoxville Utilities Board (KUB) does not currently offer rebates for whole-house filtration, but many homeowners insurance companies give modest discounts for water-quality improvements. We also provide 12-month same-as-cash financing to spread out the upfront cost.
