Under-Sink Reverse Osmosis in Royal Palm Beach

Under-sink reverse osmosis gives a Royal Palm Beach kitchen its own faucet for drinking and cooking water. Living Water's alkaline RO uses carbon stages for the chloramine that Palm Beach County Water Utilities adds, a membrane that reduces dissolved solids, and a stage that adds minerals back for taste. It is the most focused upgrade when your main concern is what you drink.

Why RO on county water

PBCWUD's water meets standards and its plants already use membranes for part of their treatment. An under-sink RO goes a step further for the few gallons a day you actually drink and cook with. It reduces dissolved solids, including the sodium the county reported at 18.2 to 49.7 ppm in 2023 sampling, and its carbon stages reduce chloramine taste.

It is also the most practical option for renters and condo owners, because it installs under one sink without changes to the main plumbing.

The stages

Sediment filter for particles from pipes, especially after hydrant flushing.
Carbon pre-filters for chloramine and chlorine, which also protect the membrane.
RO membrane to separate dissolved solids.
Alkaline stage to add minerals back and raise pH.
Polishing filter before the faucet.

See the compact alkaline RO.

Chloramine and the membrane

Many RO membranes are sensitive to disinfectants, which is one reason the carbon stages matter. Royal Palm Beach's county water carried chloramine at a 3.04 ppm highest annual average in 2025, with single samples up to 4.53 ppm. Pre-filters rated for chloramine and changed on time protect the membrane and keep the taste consistent, including during the county's twice-yearly switch to chlorine.

Fitting it in

Cabinet space for the unit and, on tank models, the storage tank.
A faucet hole in the sink or counter.
A drain connection.
An optional line to the refrigerator or ice maker.

Compare tankless vs. tank RO if space is tight.

Certification for specific concerns

RO systems are certified under NSF/ANSI 58 for specific contaminants. If you are buying for a particular concern such as PFAS or fluoride, make sure the exact model's listing names it. See PFAS filters and fluoride filters in Royal Palm Beach.

Alkaline or standard?

Standard RO water has very few minerals left and a slightly flat taste for some people. The alkaline stage adds minerals back. Compare in alkaline vs. standard RO.

Next step

Jorge tests TDS and chloramine at your kitchen tap so you can see what RO would change, then gives an itemized quote after the free test; see RO cost drivers. Living Water offers financing through its financing partners; you apply with a credit application, and a co-applicant can apply with you. Call, text or WhatsApp (305) 793-5974.

If you also dislike the chloramine smell in the shower, ask about pairing RO with a whole-home system.

Common questions

Does RO remove chloramine?

Its carbon stages reduce it before the membrane. Check the model's listing for chloramine.

Is RO a good fit for a rental?

Often, because it installs under one sink without changing the main plumbing. Ask your landlord first.

Can it feed my fridge?

Usually, with a line to the ice maker and dispenser.

How often are filters changed?

On a schedule set by the model and your water; the membrane lasts longer than the pre-filters.

Do I need a softener before RO on county water?

Usually not. The county reduces hardness at its plants. On a hard private well, the well should be treated first.

Is the TDS test free?

Yes.
