Reverse-osmosis Systems
Reverse-osmosis Systems | Water Purification | Plumbing | Farragut
Imagine crystal-clear drinking water streaming straight from the kitchen tap—no plastic bottles, no after-tastes, just pure refreshment every time you turn the handle. HEP’s reverse-osmosis systems bring that experience home to Farragut by forcing ordinary tap water through a series of ultra-fine membranes that trap sediments, chlorine, heavy metals, and even microscopic contaminants. The result is a level of water purification normally reserved for laboratories, delivered by a local team that knows East Tennessee’s plumbing inside and out.
From compact under-sink units to whole-home installations, our licensed technicians size each system to your family’s needs, handle the complete installation, and show you how simple routine filter changes can be. Enjoy fresher coffee, spotless dishes, and peace of mind, all backed by HEP’s 24/7 support—because clean water shouldn’t have a waiting period. Let us turn your home into a personal oasis, one glass at a time.
FAQs
How does a reverse-osmosis system work and why is it beneficial for Farragut homes?
A reverse-osmosis (RO) system pushes tap water through a semi-permeable membrane and several pre- and post-filters. The membrane’s microscopic pores (≈0.0001 µm) allow water molecules to pass while rejecting dissolved salts, metals, and organic contaminants. Farragut’s municipal supply is generally high quality, but it still contains hardness minerals, chlorine/chloramine used for disinfection, and trace emerging contaminants. An RO unit strips out these substances, giving you bottled-water quality at the tap, improving taste, protecting coffee makers and ice machines from scale, and providing an extra line of defense for infants or immune-compromised family members.
What specific contaminants will an RO system remove from Farragut’s municipal or well water?
Independent testing shows that RO membranes remove 95-99 % of total dissolved solids (TDS). In our service area that typically includes: • Calcium and magnesium (hardness). • Sodium, nitrate, and sulfate picked up in limestone bedrock. • Lead, copper, and iron that can leach from plumbing. • Chlorine, chloramine, and the disinfection byproducts (THMs) that affect taste and odor. • Volatile organic compounds (VOCs), pesticides, and pharmaceuticals that enter surface water. • PFAS ‘forever chemicals’ down to non-detect levels when paired with a carbon post-filter. • Cysts, bacteria, and viruses too large to penetrate the membrane. The result is exceptionally pure water that meets or exceeds NSF/ANSI 58 performance standards.
How often do I need to change the filters and membrane in Farragut’s water conditions?
For a typical four-stage RO system: • Sediment pre-filter: every 6-12 months (sooner if your water is high in silt). • Carbon pre-filter: every 6-12 months to keep chlorine/chloramine from degrading the membrane. • RO membrane: every 2-4 years, depending on incoming TDS and how diligently pre-filters are changed. • Polishing carbon post-filter: once a year for best taste. Farragut’s average TDS (150-250 ppm) and moderate chloramine levels make annual filter swaps and a membrane every 3 years realistic. Our maintenance plans include reminders, discounted cartridges, and professional installation to keep performance and warranty intact.
Can an RO system be installed under any kitchen sink, and what plumbing modifications are required?
Most kitchens in Farragut have ample space for the 2- to 4-gallon storage tank and filter housing, but we always perform a free site check. Installation steps: 1) Tie into the cold-water feed with a T-fitting; 2) Mount the filter assembly on the cabinet wall; 3) Drill a ¾″ hole in the countertop or use an existing sprayer hole for the dedicated RO faucet; 4) Run a ¼″ drain saddle line to the sink’s tailpiece or garbage disposal. Homes with granite or quartz counters may need a diamond-bit drill, which we handle. If space is tight, we offer tankless and remote-tank options that can sit in an adjacent cabinet or basement.
How much water does an RO unit waste, and are there water-saving options?
Standard residential RO units produce 1 gallon of pure water for every 3-4 gallons sent to drain (25-30 % efficiency). Farragut does experience summer watering restrictions, so efficiency matters. Modern systems with permeate pumps or pressure-boosting delivery can cut the reject ratio to 1:1 or even 2:1. We also install zero-waste RO configurations that send the concentrate line to a hot-water recirculation loop or outdoor irrigation line. Your installer can size the system for your household’s daily consumption so you’re not constantly refilling and dumping excess water.
What ongoing maintenance and costs should I expect when serviced by your Farragut plumbing team?
Upfront installed cost ranges from $425 for a compact under-sink unit to $1,200 for a high-output, remineralizing system. After that, plan on: • Filter kits: $60–$90 per year. • Membrane: $80–$120 every 3 years. • Optional annual service visit: $95, which includes sanitizing the storage tank, replacing filters, pressure testing, and water-quality verification. Our membership customers receive 10 % off parts, priority scheduling, and real-time TDS monitoring through our smartphone app. Compared with buying bottled water, an RO system usually pays for itself within 18-24 months for a family of four.
