FAQs
What is a reverse-osmosis (RO) water purification system and how does it work?
A residential RO unit pushes household water through a semi-permeable membrane that has pores small enough (≈0.0001 micron) to reject most dissolved salts, heavy metals, microorganisms, and organic chemicals. Before the membrane, the water passes through sediment and carbon pre-filters to remove rust, silt, chlorine, and chloramines that could damage the membrane. After the membrane, a final carbon “polishing” filter improves taste and odor. Purified water is stored in a small pressure tank (2–4 gal) and delivered to a dedicated drinking faucet, refrigerator, or ice maker. The process mimics natural osmosis in reverse, using household water pressure (40–80 psi) instead of energy-hungry pumps, making it both effective and economical for home use.
What specific water issues in Greeneville can an RO unit address?
Greeneville’s municipal supply is primarily surface water from the Nolichucky River and can contain hardness minerals, seasonal sediment, chlorine, chloramine, and trace agricultural runoff. Older private wells in the surrounding county sometimes show elevated iron, manganese, hydrogen sulfide, or nitrates. A properly sized RO system removes up to 98 % of dissolved solids, including lead and other metals leached from plumbing, 99 % of chlorine/chloramine by-products, and virtually all bacteria and cysts, giving Greeneville homeowners bottle-quality water straight from the tap regardless of source fluctuations.
How much water does an RO system produce and will it waste a lot of water?
Today’s 4-stage under-sink units typically carry a 50–75 gallon-per-day (GPD) membrane. In practical terms, that means about 2–3 gallons of purified water an hour, more than enough for cooking and drinking. Standard units send roughly 3 gallons of concentrate to the drain for every gallon of purified water produced (a 3∶1 ratio). High-efficiency, “zero-waste” or permeate-pump models we install in Greeneville can cut that ratio to 1∶1 or redirect concentrate to a garden or gray-water line, trimming water usage by up to 80 % compared with older systems.
How often do the filters and membrane need to be replaced and what does maintenance cost?
1) Sediment pre-filter: every 6–12 months, depending on incoming turbidity. 2) Carbon pre-filter(s): every 6–12 months; necessary to protect the membrane from chlorine/chloramine. 3) RO membrane: every 24–36 months for city water, possibly sooner for high-iron wells. A simple total-dissolved-solids (TDS) meter tells you when rejection rate drops below 80 %. 4) Post carbon/polishing filter: yearly. A complete Greeneville service call (all filters, sanitizing, TDS test, labor) averages $120–$180, much less if you perform the cartridge swaps yourself with our do-it-yourself kits.
Can you connect the RO unit to my refrigerator, ice maker, or coffee machine?
Yes. During installation we run ¼-inch food-grade tubing from the RO tank to your refrigerator’s cold-water feed or built-in coffee system. Because RO water has lower pressure, we often add a micro-booster pump for fridges with fast-fill dispensers. We also supply dual-outlet designer faucets so you can draw room-temperature purified water at the sink while automatically feeding the fridge and any remote beverage station. All tubing is NSF-certified, uses quick-connect fittings, and can be hidden behind cabinets or routed through the basement ceiling for a clean look.
What does an RO system cost in Greeneville and how does it compare with bottled water?
A high-quality 4- to 5-stage NSF-certified under-sink unit with a 3-year warranty costs $300–$600. Professional installation by our licensed Greeneville plumbers runs $150–$300, depending on cabinet modifications and fridge hookups. Replacement filters average $60–$90 per year. If a family of four currently buys two cases of bottled water a week at $5 each, they spend over $500 annually—enough to pay for the RO system in the first year. Beyond cost savings, RO water eliminates plastic waste and the hassle of hauling bottles, while providing a continuous, on-demand supply of cleaner, fresher water.
