Reverse osmosis: better drinking water at every tap.

An RO unit under your kitchen sink with its own dedicated faucet, for the water you drink and cook with. A remineralizing stage runs after the membrane so the water does not come through flat.

Think of it as a water-bottle vending machine built into your house, with a second faucet (color-matched to your existing one) just for the water you actually drink and cook with. Your regular faucet still handles the dishes; this one is for drinking, cooking, and washing produce.

Why it matters in Middle Tennessee

Nashville uses free chlorine as its disinfectant rather than chloramine, averaging 1.60 ppm in the 2025 Consumer Confidence Report, and Franklin serves a blend of Harpeth River and Cumberland River water. RO runs after the whole-home carbon and softening stages and treats the kitchen tap on its own.

What's behind the faceplate

  • A pre-carbon filter (like a large fridge filter).
  • The RO membrane, which is the stage that reduces total dissolved solids.
  • A post-carbon filter with built-in alkaline remineralization, so the water isn't stripped flat.
On TDS readings: the membrane stage lowers total dissolved solids, then the remineralizing filter adds mineral content back. A TDS meter reading taken after that last stage will read higher than one taken before it, which is expected and not a fault.

It fits under the sink and stays out of the way

The unit is about the size of a games console and takes up little under-sink space. It is usually installed at the same time as the whole-home system, since the plumbing is already open.
