Reverse Osmosis Filtration & Alkaline Systems by RT Olson Plumbing

Reverse Osmosis (RO) Provides Safe, Great-Tasting Water At Your Tap For Less!

Enjoy clean, safe, great-tasting, water right from your faucet.

Enjoy the benefits of ultra-filtered reverse osmosis drinking water that has added essential minerals for balanced pH.

  • Safe, clean, delicious water for drinking and cooking
  • Better tasting coffee, tea, & soups
  • Clean water for cooking
  • Save $$$ on bottled water
  • Great water for low-sodium diets

Stop wasting $$$ on bottled water!

Prices for bottled water are marked up 300 to 500 percent!

A good quality Reverse Osmosis system removes up to 99% of all water contaminants.

No other water filtration system is more effective.

The Reverse Osmosis filtration system is installed under your kitchen sink and will usually supply all of your daily cooking and drinking needs.

Different size RO systems can produce up to 2 gallons per day.

This is far more cost-efficient way of providing safe, clean drinking water than buying bottled water forever.

RO usually saves enough money in expensive and wasteful plastic water bottles to pay for itself in months.

Reverse Osmosis saves our landfills from plastic bottles too!

RO is better than bottled water!

The water you get from our reverse osmosis systems with essential minerals stage will be the best-tasting water you’ve ever had (unless you’ve drank from the mountain springs of Switzerland or New Zealand).

RO water is filtered and purified better than all of the over-priced bottled waters sold in stores.

Don’t forget your pets!

The cost/gallon of R.O. filtered water is so low in comparison to buying bottled water that you can happily give your pets the benefit of clean, filtered drinking water.

How reverse osmosis filtration systems work

The Reverse Osmosis (RO) process removes a wide spectrum of impurities from your drinking and cooking water.

The water is pushed through a membrane with microscopic holes in it that filters out 99.99% of everything in the water. These impurities are automatically rinsed down the drain.

RO water is acidic however, usually around 4.0, and lacks the basic healthy minerals found in Spring or rain water.

The final stage of good RO system like ours, is an Essential Minerals Filter, which runs the water through healthy minerals to raise the pH back to a balanced pH of around 7.0 to make the water taste great and be healthier.

Municipal tap water systems strive for a balanced 7.0 pH.
