Get Cleaner, Safer, Tastier Water

Forget the insanity of filling up jugs of water at the store and the expense of bottled water. There is a better, more affordable and convenient way to have crystal clear, great tasting water in your Phoenix home — reverse osmosis! Reverse Osmosis water has that same bottled water taste, but right from the convenience of your kitchen. Water treated by filtration and reverse osmosis is great for improving the taste of drinking water, coffee, tea, soups, sauces and improving the clarity of ice cubes; your bourbon will thank you. Using filtered water instead of tap water can help with other things as well, such as your humidifiers, iron, and other appliances. There are two main reverse osmosis options — 3-Stage and 5-Stage.

How 3-Stage Reverse Osmosis Works

Reverse osmosis is a simple and straightforward filtration process. It is accomplished by water pressure pushing tap water through a semipermeable membrane to remove impurities from water. This is a process in which dissolved inorganic solids (such as salts) are removed from a solution (such as water).

Step 1 – Sediment Filter (filters down to 30 Microns*)

First, the water goes into a sediment filter or pre-filter. This filter removes large particles, like silt, rust and scale, and dirt. This extends the life of the system and allows the next phase of the system to focus on smaller particles in the water.

Step 2 – Carbon Filtration (½ of a Micron)

Once the water has gone through the first filter it passes through an activated carbon filter, which is responsible for removing chlorine, odd tastes, and odors from your water.

Step 3 – Membrane

The next phase of a 3-stage reverse osmosis is the membrane, and that’s where the real magic happens. The membrane is responsible for removing the small particles that couldn’t be caught by the filter. Another fun fact — the more you use the membrane the more water it can process in its lifetime.

How 5-Stage Reverse Osmosis Works

A 5-stage system works the same as the 3-stage system, however it utilizes a second carbon filter for better chlorine removal, which is helpful in larger municipalities that tend to have a higher chlorine content in their water. The 5-stage system also has a post-filter that is installed inline to the spout that is also referred to as a polishing filter. This filter offers that last chance to remove any remaining taste and/or odor and ensures the cleanest, most delicious water possible. For the price difference, Robins Plumbing always recommends the 5-stage system over a basic 3-stage system.

Production Rates & Storage Tanks

After the water has made its way through the system, the pressure will have dropped dramatically, and it would take several minutes to fill a glass. For this reason, the system requires a storage tank. The typical storage tank will hold roughly 2-4 gallons of water total and will have a bladder (pressured to 5-7 psi) that pushes back and allows for 1-2 gallons to be used before the pressure drops back down. The tank will automatically start pressurizing as water is used, restoring usable capacity. The average reverse osmosis system can produce up to 50 gallons of water in a day, but if by chance you need more than that, you can get systems that can handle upwards of 100 gallons a day. These options are great for small businesses.

Average Cost to Own for 10 Years

Professionally installed and maintained annually:
$2,646.50 total ($0.72 per day)

Professionally installed and DIY maintained:
$1,110 total ($0.30 per day)

With a basic capacity of 2500 gallons per year/set of filters, you’ll get 6.849 gallons per day. That’s enough for 51+ standard bottles of water (16.9 oz or 500ml) at a cost of less than 2 pennies per bottle (professionally maintained) or less than 1 penny per bottle (DIY maintained).
