Reverse Osmosis Systems in Centennial

Under-sink RO for kitchens across Centennial, Lone Tree and Highlands Ranch, installed in a morning.

What reverse osmosis does for Centennial drinking water

Reverse osmosis systems in Centennial push water through a membrane that rejects most dissolved solids, along with many contaminants that carbon alone cannot catch. The result is drinking and cooking water with very low TDS and no chlorine or chloramine taste.

RO is a kitchen-tap solution, not a whole-house one. It suits households that buy bottled water, families who want an extra barrier for drinking water, and anyone whose coffee tastes flat. We check your TDS and disinfectant first, choose the right pre-filters for your district, and fit the system under the sink with its own faucet. Most installs take about two hours.

A note on minerals: RO removes calcium and magnesium along with everything else, so the water tastes very clean, almost flat to some people. If you prefer a little mineral taste back, a remineralizing stage adds a small amount after the membrane. We bring a sample glass so you can decide before we install.

What the RO install covers

A complete drinking-water station, plumbed and tested. Nothing to finish yourself.

  • TDS and disinfectant check

    We measure TDS before and after, so you can see what the membrane is doing in your house.

  • Sediment and carbon pre-filters

    Pre-filters protect the membrane; catalytic carbon goes in where the district uses chloramine.

  • RO membrane

    A certified membrane sized to your daily drinking and cooking volume.

  • Storage tank or tankless unit

    Tank systems for steady output, tankless units where cabinet space is tight. We show you both.

  • Dedicated faucet

    Mounted in an existing sprayer hole or a clean new hole in the sink or counter.

  • Drain saddle and air gap

    Installed correctly so drain water can never back up into the system.

  • Optional fridge line

    We can run a line to the refrigerator so ice and dispenser water come from the RO.

  • Sanitize and flush

    The housings are sanitized and the first tanks flushed, so the first glass you drink is a good one.

How an RO install goes

  1. Check the water and the cabinet

    We test TDS and disinfectant, look at the sink, the drain and the space, and give you a written price for the right unit.

  2. Fit the system

    We mount the filters, drill or use the faucet hole, connect the drain saddle and supply valve and leak-test every fitting. Plan on about two hours.

  3. Show you the numbers

    After flushing we measure TDS at the new faucet so you can compare it with the tap. You get a filter-change calendar on the cabinet door.

Why us for reverse osmosis

  • Pre-filters matched to your district

    Chloramine shortens membrane life if the carbon is wrong. We set it up for your water.

  • Honest about waste water

    Every RO sends some water to drain. We size and choose systems that keep that ratio sensible.

  • Easy filter changes

    We install systems with standard cartridges you can source, and we can change them for you.

  • Written flat price
  • Two-hour arrival windows
  • NSF/ANSI-certified parts
  • Brand-neutral service

Stop hauling bottled water home

One system under the sink and the jugs can go. Call and we will tell you what RO would do with your water.
