Reverse osmosis: better-tasting drinking water at your tap.

A tankless RO unit under your kitchen sink with its own dedicated faucet. It reduces dissolved solids substantially, then adds back the good minerals so your water tastes clean, not flat.

Four Streams Water Solutions reverse osmosis system installed under a kitchen sink

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 the Dallas-Fort Worth Metro

Dallas-Fort Worth utilities use chloramine as a disinfectant residual, which is effective for large-scale distribution but leaves a treatment character in the water that carbon filtration alone doesn't fully address. Reverse osmosis pushes water through a semi-permeable membrane that removes dissolved solids and treatment byproducts, then a remineralization stage adds back the right amount of calcium and magnesium. The result is clean, great-tasting tap water without touching a water bottle.

What's behind the faceplate

  • A pre-carbon filter (like a large fridge filter).
  • The RO membrane, which substantially reduces dissolved solids (TDS) and treatment byproducts.
  • A post-carbon filter with built-in alkaline remineralization, so the water isn't stripped flat.
On TDS: RO reduces dissolved solids substantially, the bad stuff included. Then the alkaline filter adds back the good kind, calcium and magnesium your body actually wants. So a higher number after remineralization is a good thing, not a bad one.

Tankless, and it shows

The tankless unit is about the size of an Xbox, takes up almost no under-sink space, and looks clean. It's included in most flagship bundles, a near-automatic yes because it's inexpensive to add while we're already installing your whole-home system.
