Reverse Osmosis Systems in Las Vegas

Under-Sink RO vs. Whole-House Treatment

Most residential RO systems are point-of-use units. They sit under the kitchen sink with a set of prefilters, the membrane, a carbon post-filter, a small storage tank and a dedicated drinking water faucet. Because RO makes water slowly, the tank keeps treated water ready when you fill a glass or a pot. In many homes the same system can also feed the refrigerator’s water and ice line.

Whole-house (point-of-entry) RO is rarely the right fit for a typical Las Vegas home. RO sends some water down the drain as it works. The EPA’s WaterSense program says a typical point-of-use RO system produces five or more gallons of reject water for each gallon of treated water, while WaterSense-labeled models must use 2.3 gallons or less. Scaling that up to every shower, toilet and sprinkler doesn’t make sense for most households.

The setup we usually recommend is simple: treat the whole house at the point of entry with a softener or a whole-house water filter, then add RO at the kitchen sink for drinking and cooking. If you only want better-tasting water and don’t need TDS reduction, a simpler point-of-use inline filter may be all you need.

Our Process and RO Maintenance Basics

1. Free water analysis. We test your water at home and walk you through the results, including hardness and TDS.
2. Honest recommendation. We size the system to your household, check whether a softener or whole-house filter should come first, and pick the best spot for the faucet and tank.
3. Professional installation. Our local team installs and tests the system. Same-day service is available, and 100% financing is offered to qualified customers.
4. Filter and membrane maintenance. We help you stay on schedule with prefilter, post-filter and membrane changes so the system keeps performing.

After installation, an RO system is only as good as its filters. LVVWD cautions that home treatment systems must be maintained, or they can actually lower water quality. Intervals depend on your water, your usage and the specific unit, so always follow the manufacturer’s schedule. As a general guide:

• Sediment and carbon prefilters are changed most often, typically every several months up to about a year. They protect the membrane from particles and chlorine.
• The carbon post-filter is commonly replaced about once a year.
• The RO membrane lasts longer. The manual referenced above suggests every 12 to 24 months, and EPA WaterSense criteria require labeled membranes to last at least one year.

Signs it’s time for service include slower flow from the RO faucet, a change in taste, or a rising TDS reading. Very hard feed water and heavy use can shorten these intervals, which is one more reason to soften first.

Why Pay For Water Twice?

You already pay for the water coming into your home. Then many Las Vegas families pay again for cases of bottled water, haul them home, store them in the garage and recycle the empties. An RO system gives you filtered drinking water straight from your own tap, on demand, for drinking, coffee, cooking and ice. No more lugging cases through the summer heat.
