FAQs
What is a reverse-osmosis (RO) system and how does it purify my water?
A residential RO system pushes tap water through a semipermeable membrane that has microscopic pores (about 0.0001 micron). Under pressure, only water molecules pass, while dissolved salts, lead, pesticides, micro-organisms, and other impurities are flushed to the drain. The purified water is stored in a small tank and delivered to a dedicated faucet or refrigerator line when you open the tap.
Why is reverse-osmosis recommended for homes and businesses in Vonore?
Vonore’s municipal supply meets federal safety standards, but many residents notice hardness minerals, chlorine taste, and occasional agricultural runoff by-products. An RO system provides an extra barrier, removing up to 99% of total dissolved solids (TDS) and chlorine, delivering crisp, bottle-quality water without the cost and plastic waste of store-bought alternatives.
How often do I need to change the filters and membrane?
Most systems use three to five stages. In Vonore’s water conditions, pre-filters (sediment and carbon) should be replaced every 6–12 months, post-filters every 12 months, and the RO membrane approximately every 2–3 years or when TDS readings climb. Our service plans include annual inspections, on-site TDS testing, and reminder notifications so you never miss a change.
What contaminants will an RO system remove from Vonore’s water?
Reverse osmosis is highly effective against dissolved salts, lead, mercury, arsenic, nitrates/nitrites, fluoride, PFAS, micro-plastics, and up to 99% of chlorine/chloramine. It also filters bad tastes and odors, leaving you with pure, neutral-tasting water ideal for drinking, coffee, tea, and cooking.
How much does installation and operation cost?
A high-quality undersink RO unit with professional installation in Vonore typically ranges from $450–$750, including a three-year parts and labor warranty. Operating costs (replacement filters, membrane, and water waste) average $60–$90 per year, or roughly 1–2 cents per gallon—far less than bottled water.
What does the installation process involve and how long does it take?
Our licensed plumbers mount the RO unit in the cabinet, connect a feed line to the cold-water supply, install the drain saddle, and drill a 7⁄16" hole in your sink or countertop for the dedicated faucet (if one isn’t already present). The job usually takes 1.5–2 hours, after which we sanitize the system, run a full tank purge, and test the water to confirm proper TDS reduction. You can start enjoying purified water the same day.
