FAQs
How does a reverse-osmosis (RO) drinking water system work, and what contaminants does it remove?
An RO system pushes your tap water through a semi-permeable membrane that has microscopic pores (about 0.0001 micron). Dissolved salts, heavy metals (lead, arsenic, chromium), chlorine by-products, nitrates, fluoride, PFAS, and most bacteria, viruses, and cysts are rejected and flushed to drain. The treated water then passes through post-filters (usually carbon) to polish taste and odor, giving you clean, bottle-quality water right at the sink.
Why is reverse-osmosis especially beneficial for homes in Dandridge, TN?
Dandridge’s municipal and well sources are generally safe, but they often contain moderate hardness, chlorine/chloramine disinfectants, and traces of agricultural runoff. These can affect taste, leave spots on glassware, and, in the case of nitrates or lead from older plumbing, pose health concerns. An RO system removes these impurities, providing great-tasting water for coffee, tea, and baby formula while protecting vulnerable family members.
How much water does an RO system waste, and can it be reduced?
Traditional 4-stage RO units send 3–4 gallons to drain for every gallon of purified water. Newer high-efficiency and tankless models we install in Dandridge cut the ratio to 1:1 or better. We also offer optional permeate-pump upgrades that use the pressure of the reject water to boost efficiency without electricity, lowering waste and improving tank refill speed.
How often do I need to change the filters and membrane?
Pre-filters (sediment and carbon) protect the membrane and should be replaced every 6–12 months, depending on water quality and usage. The RO membrane typically lasts 2–4 years, and the post-carbon ‘polishing’ filter is changed annually. We provide a simple service calendar and can place you on an annual maintenance plan so you never have to remember part numbers or schedules.
Can the RO system supply my refrigerator, ice maker, or coffee machine?
Yes. During installation we can run a 1⁄4-inch food-grade line from the RO storage tank to most fridges, freezers with ice makers, or plumbed coffee/espresso machines. This gives you crystal-clear ice cubes and better-tasting beverages. If the appliance is more than 25 ft away, we may recommend a small booster pump to maintain flow.
What does installation cost, and how long does it take?
A standard 4-stage undersink RO system with faucet starts around $450 installed. High-efficiency or remineralizing models range from $650–$900. Add-on lines to a fridge or ice maker typically cost $50–$100. Installation is completed in one visit (2–3 hours) by our licensed Dandridge plumbers, and we handle all drilling, fittings, and cleanup. Every system includes a 1-year workmanship warranty and manufacturer warranties of 3–5 years on major components.
