RiverCity Plumbing installs reverse osmosis drinking water systems in Jacksonville, FL, producing 99%+ pure drinking water directly at the kitchen sink by removing dissolved solids, nitrates, heavy metals, and chloramines that standard carbon filters cannot address — plus lead, fluoride, arsenic, and the hardness minerals behind Jacksonville's scale buildup and flat-tasting water. Under-sink 5-stage RO systems produce 50–75 gallons per day — enough for drinking, cooking, and ice production for the average Jacksonville family — with a dedicated faucet mounted on the sink deck and a 2–4 gallon storage tank in the cabinet below. Filters are replaced every 6–12 months and the RO membrane typically lasts 2–5 years. Traditional RO designs send 3–4 gallons to drain for every purified gallon; the high-efficiency models we recommend for Jacksonville homes cut that ratio to roughly 1:1 — important during summer dry periods.

Jacksonville’s Water Is Safe — But It Doesn’t Have to Taste Like It
JEA’s water meets all federal safety standards, but “safe” and “great” aren’t the same thing. Jacksonville’s water contains chloramines (used for disinfection), 15.3 GPG of dissolved calcium and magnesium, and trace levels of other compounds that create a flat, slightly chemical taste. Millions of Jacksonville residents spend hundreds per year on bottled water to avoid drinking from the tap.
A properly installed reverse osmosis system solves this permanently. RO pushes your tap water through a semi-permeable membrane that removes up to 99% of dissolved contaminants, producing water that’s cleaner than most bottled water brands — for pennies per gallon from your own kitchen faucet.
An under-sink 5-stage system produces 50–75 gallons per day — more than enough for drinking, cooking, and ice production for the average Jacksonville family. It lives quietly in the cabinet under your kitchen sink, and the only visible change is a slim dedicated faucet on the sink deck.
Why Jacksonville Tap Water Falls Short at the Glass
Chloramines From Disinfection
JEA disinfects Jacksonville’s municipal supply with chloramines. They keep water safe on its way to your home, but they also leave the faint chemical taste many people notice in a glass of tap water. An RO system’s carbon stages are designed to deal with chloramines before the water ever reaches the membrane.
15.3 GPG of Dissolved Minerals
Jacksonville draws its water from the Floridan Aquifer, and it arrives carrying 15.3 grains per gallon of dissolved calcium and magnesium. That mineral load is what makes tap water taste flat, leaves white residue in kettles and coffee makers, and turns ice cubes cloudy. The RO membrane removes the dissolved solids behind all three complaints.
What Pitcher and Fridge Filters Miss
Carbon pitcher and refrigerator filters improve taste, but they cannot address the dissolved solids, nitrates, and heavy metals that a semi-permeable membrane removes. That is the fundamental difference between filtering water and purifying it.
The Bottled Water Treadmill
Hauling cases of bottled water home every week solves the taste problem at a steep ongoing cost in money, storage space, and plastic waste. A reverse osmosis system produces water cleaner than most bottled water brands — on tap, in your own kitchen, every day.
RO System Services We Provide
Under-Sink RO Installation
Professional installation of 5-stage NSF-certified under-sink systems with dedicated faucet. Completed in 2–3 hours with immediate clean water delivery. The system connects to the cold water supply line and drain, and stores purified water in a small pressurized tank so it is ready the moment you open the tap.
Filter Replacement Service
Annual filter replacement to maintain peak performance. We change pre-filters, post-filters, and the RO membrane on a schedule that matches Jacksonville’s water quality demands. The pre-filters do the heavy lifting against sediment and chloramines, protecting the membrane at the heart of the system — a skipped filter change is the most common reason an RO system loses performance.
Whole-Home RO Systems
For homeowners who want RO-quality water at every faucet — ideal for luxury homes in Ponte Vedra with high-end fixtures requiring pure water protection. Whole-home RO is a bigger commitment than an under-sink unit, and we will tell you honestly whether your goals are better served by pairing whole-house filtration with point-of-use RO in the kitchen.
RO System Repair
Slow flow at the RO faucet, a drain line that never stops running, or a storage tank that empties after a single glass are all repairable problems. We diagnose and repair under-sink RO systems regardless of who installed them — replacing membranes, fittings, shut-off valves, and pressure tanks so you are not buying a whole new system when a part will do.
Pairing RO With a Water Softener
Jacksonville’s hardness makes the RO membrane work hard. Many local homeowners pair a kitchen RO unit with a whole-house water softener so the membrane sees softened water and drinking water gets the final polish. On a private well, start with well water treatment instead — Floridan Aquifer well water usually needs iron and sulfur addressed first.
Refrigerator & Ice Maker Connection
We can run a line from the RO system to your refrigerator so ice and chilled water come from the same purified supply. The result: clear ice and better-tasting coffee from the same small tank under your sink.
