Under-Sink Reverse Osmosis in Cutler Bay

An under-sink reverse osmosis (RO) system gives you filtered drinking and cooking water from a dedicated faucet, without treating the whole house. For a Cutler Bay home on WASD water, the carbon stages handle the chloramine taste and the RO membrane lowers dissolved minerals. Living Water installs a multi-stage alkaline RO that fits in a standard kitchen cabinet. Jorge tests your tap free and shows you what the system would change.

Why RO is popular on county water

WASD's water leaving the Orr plant has been lime-softened, filtered and disinfected with chloramine, and the main system's 2025 average was 2.5 ppm of chloramine. Most drinking-water complaints in Cutler Bay are about that disinfectant taste and about wanting water that tastes the same as bottled. RO addresses both at one tap, which is why it is often the first step for condos and townhomes, and the companion to a whole-home system in single-family houses.

How the stages work

Sediment prefilter catches particles.
Carbon stages reduce chlorine and chloramine taste and protect the membrane. On chloramine water, carbon designed for chloramine matters.
RO membrane lowers total dissolved solids.
Storage and post-filter polish the taste before the faucet.
Alkaline stage adds minerals back to raise pH, which many people prefer for taste.

For the trade-offs, see alkaline vs. standard RO.

Install details in a Cutler Bay kitchen

Cabinet space for the unit and tank.
A faucet hole in the sink or counter for the dedicated faucet.
A drain connection for the reject water.
Optional fridge or ice maker line if you want RO water there too.

Condo owners should check association rules on plumbing work; the install itself stays inside your unit.

What to know about certifications

RO systems are certified under NSF/ANSI 58. If you are buying RO for a specific contaminant, such as PFAS or fluoride, the exact model's listing must name that contaminant. Living Water does not claim its systems remove PFAS; see PFAS filters in Cutler Bay and fluoride filters.

Who it suits in Cutler Bay

RO is a good fit for households that buy bottled water every week, families who cook with a lot of water, and renters or condo owners who cannot change the main line. It is less useful if your only complaint is the smell in the shower; that is a job for a whole-home filter. If you are not sure which camp you are in, Jorge can show you a before-and-after TDS reading at your own sink during the free visit, so you decide on numbers instead of a sales pitch.

Living with it

Filters and the membrane are replaced on a schedule that depends on your water and use. Ask for the schedule in writing. For ongoing costs, read RO maintenance and operating costs and reverse osmosis cost in Cutler Bay. Jorge gives you an itemized quote after the free test. Call, text or WhatsApp (305) 793-5974.

Common questions

Does RO remove chloramine?

The carbon stages do the work on chloramine; check that the carbon is suitable for it. The membrane handles dissolved solids.

Will RO waste water?

All RO sends some water to the drain. Ask for the model's ratio and consider where your use is highest.

Can I connect my fridge?

Usually, with an extra line. Jorge checks the route during the visit.

Is alkaline RO healthier?

Living Water makes no health claim. The alkaline stage raises pH, which many people prefer for taste.

Does RO work in a condo?

Yes. It fits under the kitchen sink and stays within your unit.
