CORAL GABLES · REVERSE OSMOSIS

Under-Sink Reverse Osmosis in Coral Gables

An under-sink reverse osmosis (RO) system gives your Coral Gables kitchen its own drinking-water faucet, with water pushed through a fine membrane plus carbon stages. On WASD's chloramine-treated water, it is a popular way to get better-tasting water for drinking, coffee and cooking without treating the whole house. Jorge tests your water free at home and checks your cabinet before recommending a model.

Why Gables households choose RO

Coral Gables tap water comes from the Miami-Dade Water and Sewer Department (WASD) and is disinfected with chloramine. It meets standards, but many people do not like the taste. An RO system treats only the water you drink and cook with, which makes it a focused choice for homeowners and for renters or condo owners who cannot change the main line.

What Living Water's alkaline RO includes

  • Multi-stage filtration: pre-filters and carbon before the membrane, and polishing after it.
  • A reverse osmosis membrane that reduces a wide range of dissolved solids.
  • An alkaline stage that adds minerals back for taste.
  • A dedicated faucet at the sink.

For specific contaminants, check that the exact model is certified for that contaminant under the relevant NSF/ANSI standard (NSF/ANSI 58 covers RO systems). See the compact alkaline RO page.

Fitting RO into an older Gables kitchen

Many Coral Gables homes have remodeled kitchens in older shells. Before installing, Jorge checks:

  • Cabinet depth and space around the garbage disposal
  • The cold-water supply valve and its condition
  • Where the system's drain line can connect
  • Whether your countertop can take a new faucet hole, or if an existing one can be used

Stone countertops are common in renovated homes, so the faucet location gets planned with you.

Fluoride and RO

Some people ask about RO because of fluoride. WASD stopped adding fluoride as of June 6, 2025, and reports natural levels of about 0.1 to 0.3 ppm since then. RO is a common method for reducing fluoride; if that matters to you, look for a model certified for fluoride reduction. More on fluoride filters in Coral Gables.

Upkeep

RO filters and the membrane need replacing on a schedule that depends on your water and usage. Ask any installer for the replacement schedule in writing. Read RO maintenance and operating costs and reverse osmosis cost in Coral Gables.

Common questions

Does reverse osmosis remove chloramine?

RO systems rely on carbon stages to handle chlorine and chloramine before the membrane. Check the model's documentation for chloramine performance.

Can I install RO in a rental or condo in Coral Gables?

Often yes, since it sits under the sink. Check with your landlord or association first.

Does RO waste water?

RO sends some water to the drain as it filters. The amount depends on the model and your water pressure; ask for the figure on the model you are considering.

What does the alkaline stage do?

It adds minerals back after the membrane, mainly to change taste. It is a taste preference, not a health treatment.

Should I get RO or a whole-home filter?

RO is for drinking and cooking water at one sink. A whole-home filter treats every tap for chloramine. Many homes use both.
