Reverse Osmosis Installation in Lake Mary, FL
If you live in Lake Mary, FL — anywhere from the I-4 / 17-92 commercial corridor to the older neighborhoods south of Lake Mary Boulevard — this page is for you. In short, a reverse osmosis Lake Mary install solves the city’s hard-water profile and the residual chlorine that affects taste from the kitchen tap. As a result, this page covers what’s in your tap water, why most Lake Mary homes need a softener + RO combo, and what we charge installed.
Moreover, Lake Mary sits in southern Seminole County, between Heathrow (north) and Longwood (south), with its own incorporated city government and city water utility. Specifically, ZIP 32746 covers the Lake Mary Boulevard corridor, the Crystal Lake / Lake Emma neighborhoods, the Greenwood Lakes area, the Timacuan and Heathrow developments, and the older sections around Country Club Road. Median household income runs about $116,000 per 2024 ACS data — solidly upper-middle, with a healthy mix of pre-1990 ranch homes and post-2000 master-planned communities.
Furthermore, this page covers what’s actually in your Lake Mary water, why even brand-new construction benefits from an RO, and our 4-step install process.
What’s actually in Lake Mary water?
Lake Mary is served by the City of Lake Mary Utilities, separate from OUC. Specifically, the city draws from the Floridan Aquifer through wells inside city limits. As a result, the water profile is similar to OCU’s but the disinfection details are city-specific — for the most current testing data, see the City of Lake Mary Water & Sewer department.
Typical chemistry across the Lake Mary system:
- Hardness: 8 to 10 grains per gallon — moderately hard to hard. Anything above 7 gpg leaves visible scale on faucets and shortens appliance life.
- TDS: 290 to 340 ppm. A whole-house RO brings that under 20 ppm.
- Disinfection: Residual disinfectant per the City’s annual Consumer Confidence Report. The carbon pre-filter on a whole-house RO handles the residual before the membrane.
- pH: Slightly alkaline, typically 7.6 to 8.2.
- PFAS: The City of Lake Mary participates in EPA’s UCMR 5 monitoring. Specifically, EPA’s 2024 rule sets MCLs for six PFAS compounds. A whole-house RO rejects PFAS at 95%+ efficiency regardless of current levels.
- Lead: Non-detect at the City’s distribution sample points. However, older Country Club Road homes built before 1988 may have legacy service-line solder.
In short, the water is safe to drink by EPA standards. The case for an RO in Lake Mary is appliance protection, drinking water quality, and consistent water across all fixtures in the house.
Why a reverse osmosis Lake Mary install pays off
Several Lake Mary-specific reasons we hear most often:
- Premium appliances are the norm in Lake Mary. Specifically, KitchenAid, Bosch, Sub-Zero, Wolf, and Miele appear in most Timacuan, Heathrow, and Greenwood Lakes builds. Manufacturer specs typically call for water under 7 gpg hardness. However, Lake Mary water runs 8-10 gpg.
- Glass shower enclosures and stone countertops. Hard water etches glass and dulls travertine, marble, and quartzite. Specifically, $300+ frameless shower enclosures and $5,000+ stone bathrooms are standard in Lake Mary master baths.
- Coffee, tea, and ice taste. The chlorine residual is noticeable in cold water from the fridge dispenser. Furthermore, a whole-house RO removes the residual disinfectant and the dissolved minerals.
- National-chain prices vs ours. Specifically, Spring Water Fresh dominates the Lake Mary market and quotes higher. In contrast, our flat-rate $2,950 whole-house RO often comes in 30-40% under their quote for a comparable system.
The reverse osmosis Lake Mary system we recommend
Almost every Lake Mary home is a good candidate for one of two options:
Option 1 — Whole-house alkaline reverse osmosis alone. $2,950. Specifically, if your home was built 2010 or later with high-efficiency appliances, this is usually the right call. The RO removes TDS, residual chlorine, PFAS, and trace contaminants.
Option 2 — Softener + whole-house RO combo. $4,150. However, if hardness scale is already a visible problem (white film on shower glass, spots on glassware, scale on faucets), add the softener. As a result, it removes calcium/magnesium before the RO, extending membrane life 3 to 5x.
Pricing — all-in, no surprises
| System | Price installed |
|---|---|
| Under-sink RO (kitchen only) | $495 – $895 |
| Whole-house alkaline RO | $2,950 |
| Water softener add-on | $1,200 |
| RO + softener combo | $4,150 |
Additionally, we publish these prices because we prefer customers who know what they’re buying. You’ll get a written quote inside 2 business days of a phone call. Annual maintenance plan: $195/year (optional).

FAQ — reverse osmosis Lake Mary questions
Is Lake Mary water from OUC or its own utility?
Lake Mary has its own city utility — the City of Lake Mary Water & Sewer department. Specifically, it draws from the Floridan Aquifer through wells inside city limits, separate from OUC’s system that serves Orlando proper.
How hard is Lake Mary water?
Typical Lake Mary system data shows 8 to 10 grains per gallon — moderately hard to hard. As a result, you’ll see it as scale on faucets, white film on shower glass, and shortened appliance life.
What disinfectant does the City of Lake Mary use?
The City uses a residual disinfectant in its distribution system per its annual Consumer Confidence Report. Specifically, the carbon pre-filter stage on a whole-house RO removes residual disinfectant before it reaches the membrane.
How does your price compare to Spring Water Fresh in Lake Mary?
Our flat $2,950 whole-house alkaline RO often comes in 30-40% under a comparable Spring Water Fresh quote for the same equipment. Specifically, we don’t run commission-based sales, we don’t include long-term financing markup, and we don’t quote higher in Lake Mary than we do in adjacent neighborhoods.
Can you install in a Timacuan or Heathrow home?
Yes. Specifically, we coordinate gate access in advance for the gated communities. Furthermore, water treatment systems mount inside the garage or utility room — no exterior changes, no HOA architectural review needed in most cases.
How long does the install take?
4 to 6 hours for the standard softener + RO combo. Specifically, mounted in the garage or utility room with minor drywall cut for the brine line.
How often does the system need service?
Annually: pre-filter swap (10 minutes) and membrane flush. In addition, every 3 to 5 years: replace the RO membrane. We offer a $195/yr service plan that covers the annual.
