FAQs
What contaminants can a whole-house filter remove from Johnson City’s municipal or well water?
Properly configured point-of-entry systems can trap sediment, sand, rust, and silt common in the Watauga River supply; cut chlorine, chloramine, and their taste/odor byproducts; reduce lead that may leach from older service lines; lower levels of volatile organic compounds (VOCs) and pesticides sometimes detected in private wells; and remove up to 99.95 % of cysts such as Giardia. If hardness is a concern (Johnson City water averages 4–6 grains per gallon), you can pair the filter with a softening or scale-control module.
Do I need a licensed plumber to install a whole-house filtration system?
Yes. A whole-house unit must be tied into the main water line at the point of entry, downstream of the shut-off and pressure-reducing valve. In Tennessee, state code requires a licensed plumber for work that alters the potable water distribution system. A pro will size the bypass loop, verify local pressure (usually 55–70 psi in Johnson City), and obtain any needed city permits so your warranty and homeowner’s insurance remain valid.
How often will I have to change the filter media or cartridges?
Sediment pre-filters typically last 3–6 months, carbon block cartridges 9–12 months, and catalytic carbon or mixed-media tanks 5–10 years before a rebed is needed. Actual life depends on usage (average Johnson City household uses ~3,000 gallons/month) and incoming water quality. Your installer will perform a baseline water test and set a replacement schedule; modern systems include differential-pressure gauges or Wi-Fi monitors that alert you when flow is restricted.
Will a whole-house filter also soften my water or eliminate scale?
Standard filtration removes particulate and chemical contaminants but does not significantly lower hardness. If you want to prevent scale on fixtures and appliances, ask for a combo system: either a traditional ion-exchange softener installed after the filter or a salt-free template-assisted crystallization (TAC) unit. Your plumber can test hardness and recommend whether a softener is warranted based on your fixture type and personal preference.
How much does a complete installation cost and what savings can I expect?
Most Johnson City homeowners spend $1,200–$3,000 for a professionally installed cartridge-based system and $2,500–$5,000 for a high-flow tank-style or filter-plus-softener package. Operating costs run $80–$150 per year for replacement cartridges and under $25 for electricity (if any). Savings come from longer appliance life, fewer plumbing repairs, reduced bottled-water purchases, and less spending on soaps and detergents—often offsetting the investment within 3–5 years.
Will installing a whole-house filter reduce my water pressure or flow?
Correctly sized systems are rated for 12–15 gallons per minute, enough for multiple simultaneous showers. Your plumber will match filter port size (usually 1″) to your main line, account for your home ’s peak demand, and add a bypass valve for maintenance. Any minor pressure drop (2–5 psi) is typically unnoticeable; if your home already has low pressure, a booster pump or larger media tank can be specified to keep flow strong.
