Our licensed plumbers install and repair both, with a clear price before work starts. Same-day appointments are available when the schedule allows.
Start by testing your tap
We do not state a hardness number for Casselberry, because the city's 2025 water quality report does not give one. Guessing would send you to the wrong equipment. Test your tap with a lab kit or a local water test, and treat that result as your starting point.
Also ask the City of Casselberry Utilities Department for its annual water quality report, which is the primary source on what the city treats and tests. Hardness can vary between the wells, the pipes and your own plumbing, so your tap is the final word.
What the city's 2025 report does say
The report describes the supply, and it helps you decide which treatment fits.
Groundwater source
The water comes from wells in the Floridan Aquifer at three facilities: North Plant, South Plant and Howell Park.
Aeration for sulfur odor
Aeration reduces the rotten-egg smell at the plant. A smell that remains only at a hot tap may come from your water heater, not the supply.
Chlorine and orthophosphate
The city disinfects with chlorine and adds orthophosphate for corrosion control. A chlorine taste is a carbon filter job, not a softener job.
Carbon at the South Plant
The South Plant also uses granular activated carbon filtration, so ask the utility which plant serves your street.
Problem versus what actually treats it
| Problem | What treats it | What does not |
|---|---|---|
| White crust on fixtures, spotting on glass | Water softener, after a test confirms hardness | A carbon filter |
| Chlorine taste or smell | Activated carbon, whole-house or under-sink | A softener |
| Sulfur or rotten-egg smell | Depends on the source. Check the heater first | A softener alone |
| Sand or grit in aerators | Sediment filter ahead of fixtures | A softener |
| Taste at the drinking tap only | Under-sink carbon or reverse osmosis | Whole-house softening |
Whole-house or under-sink?
A whole-house system treats every tap, the water heater and the appliances. That helps with scale and chlorine across the home, and it protects the plumbing downstream. It also takes space, drain access and a bypass.
An under-sink filter treats one tap, often the kitchen, at far lower cost and with no drain work. If your only complaint is the taste of drinking water, start there. If spotting and scale show up all over the house, a whole-house system is worth a look.
Honest limits
A softener swaps hardness minerals for sodium or potassium. It does not remove chlorine, bacteria or most chemicals. Carbon filters handle taste and odor and need cartridge changes on schedule. We do not make medical claims, and we do not say any system makes water safe to drink.
If a lab test shows a contaminant, bring the report and talk with your utility or health provider before buying equipment. We can then size the plumbing work around the real result.
How an installation is planned
- We review your test results and your complaint, then agree on what to treat.
- We pick a spot near the main line with power, floor space and a drain for the backwash or discharge.
- We install bypass valves, so you can take the system out of service without shutting off the house.
- We set the unit's controls, flush the media and check every connection for leaks.
- We show you how to add salt or change cartridges, and where the bypass sits.
Water conditioner repair
If your softener or conditioner stopped working, the usual culprits are a salt bridge in the brine tank, a stuck valve, a clogged injector, a dead control board or a drain line that has kinked or clogged. Check that the unit has power, the bypass is not open and the salt is not caked.
If those look fine, call us and bring the model number. Related fixtures may also need attention, such as a dripping faucet where scale built up.
What shapes the cost of water treatment
You get a clear price before work starts. Here is what moves it.
Type of treatment
Softeners, carbon filters, sediment filters and reverse osmosis units cost very different amounts.
Whole-house or point-of-use
One kitchen tap is much simpler than a system on the main line.
Drain and power access
A unit far from a drain or outlet needs extra piping or wiring.
Capacity and flow
A larger household needs more flow, which means larger tanks and fittings.
Permit steps
Permit rules vary, so ask the Casselberry Building Division.
Homeowners insurance usually covers sudden and accidental damage but typically not water treatment equipment, wear or gradual leaks. Check your policy.
Related plumbing that treatment often touches
Treatment equipment can push a water heater to work harder or reveal scale in its tank, so our water heater repair page explains what scale does inside a tank. If you plan a new heater alongside the equipment, see the water heater installation page for sizing.
If you are in Fern Park or the surrounding area, our Fern Park service page shows what we cover. We also serve Casselberry and nearby towns from Semoran Boulevard.
Frequently asked questions
We do not state a figure. The city's 2025 report does not give a hardness value, so test your tap and ask the City of Casselberry Utilities Department for its annual water quality report.
No. A softener treats hardness minerals. Chlorine taste is handled by activated carbon, either at one tap or across the whole house.
According to the 2025 report, the city disinfects with chlorine and adds orthophosphate for corrosion control. Wells are aerated to reduce sulfur odor, and the South Plant also uses granular activated carbon.
If only drinking water bothers you, an under-sink filter is the simpler option. If spotting, scale or odor affects the whole home, a whole-house system fits better.
Look for power, an open bypass, a salt bridge in the brine tank and a kinked drain line. If all look fine, the valve, injector or control board may need service.
We do not make that claim. Filters improve taste and odor or catch particles. For health questions, check your utility report and talk with a health professional.

For what is in your water, read the City of Casselberry 2025 Consumer Confidence Report, available from the City of Casselberry Utilities Department. The report gives no hardness figure, so test your tap. Installation follows the maker's instructions and the Florida Building Code, Plumbing (8th Edition, 2023).
