For homes on municipal water
City water, refined for your home
Your utility delivers safe water. A Seastone city-water system refines it — softening it, polishing the taste, and protecting the fixtures and appliances you've invested in.
What city-water households notice
The problems softening and filtration are built to solve
- Hardness & scaleSouthwest Florida's water travels through limestone, so municipal supply commonly arrives hard. Scale shows up on shower glass, fixtures, and inside water heaters.
- Chlorine taste & odorUtilities disinfect water to keep it safe in the distribution system. Many households simply prefer not to taste or smell it at home.
- Spotting & filmMineral spotting on dishes, glassware, and dark fixtures that comes back no matter how often you clean.
- Dry skin & dull hairHard water can leave a residue that makes skin feel tight after a shower and hair harder to manage.
- Appliance wearScale buildup makes water heaters and dishwashers work harder; softening is designed to reduce that buildup over time.
A two-minute education
Softening and carbon filtration do different jobs
Most city-water complaints trace back to two separate causes — which is why a complete system uses two kinds of media.
Softening (ion exchange)
Softening resin exchanges dissolved calcium and magnesium — the hardness minerals — for sodium ions. It's the part of the system designed to reduce scale, spotting, and the dry-skin feel. It does not address chlorine taste; that's not its job.
- Scale on glass and fixtures
- Spotting on dishes
- Soap that won't lather
- Water-heater buildup
Carbon filtration
Activated carbon adsorbs disinfectant byproducts and is designed to reduce chlorine taste and odor as water passes through. It's the part of the system aimed at how water tastes and smells — but it won't soften anything on its own.
- Chlorine taste at the tap
- “Pool water” smell in the shower
- Off flavors in coffee and cooking
- Protecting softening resin downstream
A complete city-water system layers both — one properly sized unit, two jobs done at once.
Inside the system
The Complete City Water System
A single-tank configuration that treats water once, at the point of entry, so every tap and appliance in the house benefits. Here's what the water passes through:
- 1Sediment polishing bedA gravel underbed and media layering capture fine particulates so downstream media stays effective.
- 2Catalytic activated carbonCarbon media designed to reduce chlorine taste and odor as water passes through the tank.
- 3High-capacity softening resinIon-exchange resin designed to reduce dissolved calcium and magnesium — the source of scale and spotting.
- 4Metered control valveA programmable valve measures actual water use and regenerates only when needed, conserving salt and water.
Sizing matters
Why we size to the home, not the brochure
An undersized system runs out of capacity mid-week and lets hard water slip through; an oversized one wastes money and salt. We size around the details of your household so the system is designed to keep up without waste.
Service line & flow
Pipe size and available flow set the ceiling for valve selection.
Bathrooms & fixtures
Peak demand — morning showers plus laundry — drives tank sizing.
Tested hardness
Actual grains-per-gallon from your analysis, not a county average.
Household habits
Occupants, irrigation, and usage patterns shape regeneration settings.
Pairs well with
Add reverse osmosis at the kitchen sink
Whole-home treatment handles comfort and protection; a compact RO system adds a dedicated tap of highly polished water for drinking, coffee, and ice — a popular combination for households ready to retire the bottled-water habit.
Living with it
Maintenance, honestly
- Keep salt in the brine tank — for most families that's a bag every month or two.
- The metered valve regenerates automatically based on actual use.
- Carbon media is inspected periodically and replaced when exhausted — we'll tell you the expected interval for your water at installation.
- You get a written, plain-English maintenance schedule before we leave.
City water FAQs
Common questions from municipal-water households
What is the difference between filtration and softening?
Softening uses ion-exchange resin to reduce dissolved calcium and magnesium — the minerals that cause scale and spotting. Filtration passes water through media such as activated carbon or sediment filters to reduce things like chlorine taste, odor, and particulates. Many whole-home systems combine both, because they solve different problems.
Do I need a water test before choosing a system?
For city water, a quick on-site test plus your utility's published water quality report usually gives us what we need. For private wells, testing isn't optional — iron, manganese, sulfur, pH, and hardness vary well to well, and the right equipment depends entirely on those numbers. That's why every Seastone recommendation starts with a water analysis.
Can one system treat both hardness and chlorine?
Yes. A common city-water configuration layers catalytic activated carbon and softening resin so a single, properly sized system is designed to reduce both hardness and chlorine taste and odor. Whether one tank or two makes more sense depends on your household size and water conditions.
Will a system reduce my water pressure?
Any device plumbed into a water line introduces some resistance, so honest sizing matters. We select valve and tank sizes around your home's service line, fixture count, and peak demand so the system is designed to maintain the flow your household actually uses. Undersized equipment is the usual cause of pressure complaints — and it's avoidable.
How much maintenance is required?
For most softening systems: keep salt in the brine tank and let the metered valve handle regeneration. Carbon and specialty media are inspected periodically and replaced when exhausted, and RO systems need filter changes roughly every 6–12 months depending on use. At installation we set out a plain-English maintenance schedule for your exact configuration.
Where is the equipment installed?
Whole-home equipment is installed at the main water line — in this area that's usually in the garage or at an exterior wall near where the line enters the home. RO drinking-water systems typically mount under the kitchen sink with their own dedicated faucet. We confirm placement during the in-home visit.
