FAQs
How does a reverse-osmosis (RO) system work, and what contaminants will it remove from Ooltewah’s municipal or well water?
An RO system pushes household water through a semi-permeable membrane that has pores roughly 0.0001 micron wide—small enough to screen out most dissolved salts, heavy metals, fluoride, nitrates, industrial chemicals, PFAS, and microbes. Ooltewah’s public water typically meets federal standards but still contains trace levels of chlorine, chloramine, hardness minerals, and occasional agricultural runoff. Our five-stage RO units first use sediment and carbon pre-filters to trap rust, dirt, and chlorine/chloramine that can damage the membrane. The membrane then removes 95–99 % of dissolved solids. A post-carbon “polishing” filter improves taste, and an optional remineralizer adds healthy calcium and magnesium. The result is bottled-water quality straight from your tap.
Where in my Ooltewah home can an RO unit be installed, and will it require major plumbing changes?
Most residential systems fit neatly under the kitchen sink and connect to the cold-water supply line with a simple angle-stop adapter. They discharge the small amount of reject water into the sink’s drainpipe using a saddle valve and include a dedicated drinking-water faucet drilled through the sink deck or countertop (usually a 7⁄16–½-inch hole). If space is limited, we can mount a compact manifold in a nearby cabinet or basement and run ¼-inch tubing to a remote faucet or refrigerator ice maker. Because we use push-fit quick-connect fittings, installation normally takes 2–3 hours and requires no structural changes, drywall removal, or electrical work—the system runs on household water pressure.
How often do the filters and membrane need service, and do you handle maintenance in Ooltewah?
Pre-filters (sediment and carbon) are replaced every 6–12 months, depending on water quality and usage. The RO membrane typically lasts 2–3 years, and the post-carbon filter is changed annually. We offer hassle-free service plans for Ooltewah residents that include automatic reminders, discounted filter packs, and optional in-home visits. During a maintenance visit we sanitize the storage tank, check TDS (total dissolved solids) to verify membrane health, inspect fittings for leaks, and reset filter-change indicators. Homeowners who prefer DIY can purchase OEM filters at our showroom on Apison Pike or order online for free local delivery.
Will an RO system increase my water bill, and how efficient are the units you install?
A typical 4:1 recovery ratio means that for every gallon of purified water produced, about four gallons flow to drain. With our high-efficiency membrane and permeate-pump upgrades, that ratio can be reduced to 1:1–2:1, saving roughly 700–900 gallons per year for an average family—less than $2 on the typical Ooltewah water bill. The system produces 50–75 gallons of drinking water per day, plenty for cooking, coffee, pets, and ice. Because only the reject water goes down the drain, normal household uses such as showers and laundry remain unaffected.
Are your RO units certified and safe, and do they improve taste without stripping beneficial minerals?
All models we install carry NSF/ANSI Standard 58 certification for contaminant reduction and material safety. The housings and tubing are BPA-free and rated for potable water. For customers concerned about low mineral content or slightly acidic pH, we offer an alkaline remineralization cartridge that reintroduces food-grade calcium and magnesium, raising the pH to a pleasant 7.5–8.5 and giving the water a crisp, natural taste. The remineralizer clicks into the final stage, adds less than 1 ¢ per gallon to operating cost, and can be replaced yearly like any other filter.
What are the upfront and ongoing costs of an RO installation in Ooltewah, and do you offer warranties or financing?
A standard under-sink RO package—including five-stage system, 3-gallon pressurized tank, dedicated faucet, and professional installation—starts at $525. Optional upgrades (alkaline filter, permeate pump, refrigerator line) add $50–$120 each. Annual filter sets average $70, and membrane replacement runs about $90 every 2–3 years. We back the units with a 1-year labor warranty plus a 3-year manufacturer warranty on tanks and manifolds; membranes and filters are consumables. Interest-free financing up to 12 months is available for purchases over $300, and multi-system discounts apply for new-build homes or light commercial applications in the greater Chattanooga/Ooltewah area.
