FAQs

What advantages does a reverse-osmosis (RO) water purification system offer Karns homeowners over traditional filtration methods?

An RO unit forces water through a semipermeable membrane that removes up to 99% of dissolved salts, heavy metals, fluoride, nitrates, PFAS, and other contaminants that standard carbon filters often leave behind. This creates water that tastes cleaner, protects coffee makers and ice machines from scale, and provides an extra barrier of safety for families—especially important in areas like Karns where well-water minerals or aging municipal pipes can introduce additional impurities.

How is an RO system installed in my Karns residence, and will it require changes to existing plumbing?

Most residential RO units are installed under the kitchen sink. Our licensed Karns plumbing technicians tap into the cold-water supply line with a feed adapter, mount the pre-filters, membrane housing, and storage tank, and then run a dedicated purified-water line to a separate faucet on the sink deck. We also connect a small drain saddle to the sink’s waste line to dispose of the concentrate (rejected water). No major pipe rerouting is necessary, and the entire job typically takes 2–3 hours.

How much water does an RO unit waste, and can I minimize it?

A modern 4-stage system typically produces 3–4 gallons of reject water for every gallon of purified water. To reduce waste, we offer high-efficiency membranes rated at 1:1 or 2:1, permeate-pump upgrades that reuse hydraulic pressure, and optional drain-water collection for landscape use. During your on-site estimate in Karns, we’ll calculate the best configuration to balance water savings with purification performance.

What maintenance is required and how often should filters be replaced?

Three pre-filters (sediment, carbon block, and carbon polishing) normally need replacement every 6–12 months, depending on Karns’ incoming water quality and household usage. The RO membrane typically lasts 2–3 years, while the post-carbon filter can serve 12–24 months. We offer an annual service plan that includes filter changes, membrane TDS testing, sanitizing of the storage tank, and inspection of all fittings to ensure leak-free operation.

Is an RO system safe for people on low-mineral or restricted-sodium diets?

Yes. The RO process removes almost all dissolved minerals, sodium included, so it is ideal for individuals monitoring sodium intake. If you prefer some remineralization for taste or pH balance, we can add an alkaline filter stage that reintroduces healthy levels of calcium and magnesium without significant sodium content.

What warranties and certifications do your Karns RO systems carry?

We install NSF/ANSI 58-certified units, ensuring they meet strict standards for contaminant reduction and material safety. The manufacturer’s warranty generally covers the RO membrane for 3–5 years and components for 1 year. Our Karns plumbing company extends this with a full 2-year labor warranty, so if anything leaks or underperforms within that period, we handle repairs or replacements at no charge.
