FAQs
What is reverse osmosis and how does it improve my drinking water in Chattanooga?
Reverse osmosis (RO) is a multi-stage filtration process that pushes municipal water through a semipermeable membrane. The membraneâs microscopic pores (â0.0001 micron) block dissolved salts, chlorine by-products, lead, PFAS, pesticides, and many other contaminants common in Tennessee River source water. The result is clean, great-tasting water delivered straight from a dedicated faucet or refrigerator line, without the plastic waste or cost of bottled water.
Why is an RO system a smart choice for Chattanooga homes specifically?
Chattanoogaâs treated water is safe but still contains hardness minerals, residual chlorine/chloramine, and trace industrial contaminants from our river basin. An RO system provides an extra barrier that homeowners control, reducing 95â99 % of total dissolved solids (TDS) and all but eliminating chlorine taste/odor. This can be especially important for families with infants, immune-compromised members, or anyone on sodium-restricted diets who want low-TDS drinking water.
How is a reverse-osmosis unit installed in my kitchen or throughout the house?
Most customers opt for a point-of-use RO unit installed under the kitchen sink. We tap into the cold-water line, mount prefilters, the RO membrane housing, a 2â4 gal storage tank, and a dedicated lead-free faucet on the sink deck. Tubing can also route RO water to your refrigerator or ice maker. Whole-house (point-of-entry) RO systems are possible but require larger equipment and a storage cistern; theyâre mainly used for well water or specialized applications. Our licensed plumbers handle permitting, drilling the countertop (if needed), leak-testing, and a full demonstration before we leave.
How much water and energy does an RO system use, and will it raise my utility bills?
Modern 4-stage units typically waste 2â3 gallons of rinse water for every gallon producedâsubstantially less than older 5â7:1 systems. At the average Chattanooga water rate (â$0.006/gal), that equates to only a few dollars per year for a family of four. The system relies on your homeâs line pressure, so it consumes virtually no electricity unless you add an optional booster pump for low-pressure wells or commercial setups.
Does RO remove healthy minerals, and is remineralization necessary?
Yes, reverse osmosis strips out most calcium, magnesium, and potassium along with contaminants. For many people, the lower mineral content is not an issue because we receive the bulk of our daily minerals from food, not water. If you prefer mineralized taste or want the alkalinity restored, we can add a post-filter calcite cartridge that raises pH and dissolves a small amount of calcium back into the water. Either optionâpure or remineralizedâis completely safe; it comes down to personal taste.
What maintenance does an RO system require and what will it cost?
1) Sediment & carbon prefilters: replace every 6â12 months ($25â$40 total) to protect the membrane and keep chlorine out. 2) RO membrane: change every 2â3 years ($60â$90) depending on feed-water quality and usage. 3) Post-carbon or remineralization filter: swap every 12 months ($20â$35) to maintain fresh taste. We offer annual service plans that include filters, sanitizing the system, pressure checks, and leak inspection. A well-maintained RO unit should provide 10â15 years of reliable service with minimal operating costsâusually less than 35 ¢ per day for a familyâs entire drinking and cooking supply.
