FAQs
How does a reverse-osmosis (RO) system improve water quality in Loudon?
Loudon’s municipal and well supplies can contain hardness minerals, chlorine or chloramines, nitrates, and trace metals such as lead. A reverse-osmosis system forces water through a semi-permeable membrane that screens out particles down to 0.0001 microns—much smaller than what a standard carbon or sediment filter can handle. The result is water that is up to 99 % free of dissolved salts, chemicals, and heavy metals, giving you safer, better-tasting drinking and cooking water right from a dedicated faucet.
What contaminants will your RO filtration remove that typical filters do not?
Our multi-stage RO units remove a broad range of impurities, including arsenic, chromium, fluoride, nitrates/nitrites, lead, mercury, PFAS ("forever chemicals"), sodium, and pharmaceutical residues. Standard pitcher or refrigerator filters mainly handle chlorine taste and odor; they do not significantly reduce dissolved solids or heavy metals. An RO system combines sediment pre-filtration, carbon adsorption, a high-rejection RO membrane, and a final polishing post-filter, giving you bottled-water quality straight from the tap.
Where is an RO system installed in my Loudon home and how much space does it need?
Most residential RO systems are compact and mount under the kitchen sink. A typical unit includes three to five vertical filter housings, an RO membrane, and a 3–4 gallon storage tank. You’ll need roughly 18" W × 16" D × 16" H of clear space. If cabinetry is tight, we can install the tank remotely—such as in a nearby basement ceiling or adjoining cabinet—and run ¼-inch tubing to the dispensing faucet.
How often do I need to replace filters and membranes, and can you service them?
Pre-filters (sediment and carbon) should be replaced every 6–12 months depending on your water’s sediment load and chlorine level. The RO membrane usually lasts 2–3 years in Loudon’s average water conditions, while the post-carbon “polishing” filter is swapped annually. We offer annual or semi-annual maintenance plans that include filter changes, sanitizing the system, checking water pressure, and testing total dissolved solids (TDS) to ensure your membrane is still performing.
Will an RO system waste a lot of water, and are there water-efficient options?
Traditional RO units discharge 3–4 gallons of concentrate (brine) for every gallon of purified water produced. Newer high-efficiency systems with permeate pumps or 1:1 recovery membranes cut waste by up to 75 %. For customers on metered city water or private wells, we recommend these advanced models or adding a permeate pump upgrade to reduce wastewater and speed tank refill times.
How much does professional RO installation cost in Loudon and what warranties do you offer?
A complete under-sink RO package, professionally installed by our Loudon plumbing team, starts around $575 for a 4-stage system and averages $725–$900 for high-efficiency 5- or 6-stage units. Pricing includes all parts, labor, a dedicated lead-free faucet, and drilling services if needed. We provide a 1-year workmanship warranty, 1-year coverage on filters, and 3–5 years on the RO membrane and tank, depending on the model. Extended service plans are available for long-term filter and membrane replacements at discounted rates.
