Install a Reverse Osmosis System to Improve the Taste of Your Water

Isley’s Home Service sells, maintains, installs and replaces reverse osmosis systems in homes and businesses in the Gilbert, AZ, and greater Phoenix area. It’s typically a point-of-use system, rather than a whole house water purification. Read on to learn more, or call us at 480-422-5949.

Sometimes referred to as RO, reverse osmosis is primarily a point-of-use water purification system that improves both the quality and taste of drinking water in homes and businesses. Most consumers choose an under-sink installation with connection to a bar faucet, making it simple to use RO water only for consumption. You may also connect your reverse osmosis system to your refrigerator’s water and ice dispensers.

Reverse osmosis removes a wide variety of particles from your water, including arsenic, aluminum, chloride, iron, lead, and mercury. It may also remove pesticide residue.

Common questions about reverse osmosis

A basic RO system first moves water through a carbon pre-filter, which removes a variety of organic contaminants such as sediment and chloride. From there, the water enters the reverse osmosis membrane. This tight, sheet-like substance filters out other solids, such as arsenic and lead. The water passing through the RO membrane enters the unit’s storage tank while the minerals and contaminants get flushed away. Once you open the faucet, the water then moves through a second carbon filter, which removes any remaining contaminants before dispensing the water.

The Ultima 7 RO system used by Isley’s is a five-stage system. Water first passes through a sediment filter and then two carbon filters before reaching the RO membrane and the storage tank. When you turn on the faucet, it goes through one final in-line filter.

Where RO uses filters and the membrane to remove contaminants, a distiller boils the water. The boiling chamber captures most of the contaminants, while the distiller captures the steam and condenses it into drinking water. Most distillers also use a carbon filter, but not all of them. Without a carbon filter, the distiller does not capture certain contaminates with a low boiling point, such as chloride.

An RO system does use a small amount of water to clean itself when replenishing the storage tank. The daily amount of water used for cleaning the system is roughly the equivalent of flushing the toilet two or three times.

Yes, in most cases. When ordering your RO system, let us know that you’d also like to connect it to your refrigerator/freezer.

No, water pressure powers a reverse osmosis system. However, if you choose a unit with an ultraviolet lamp or pressure-boost pump, you do need electricity. Most RO systems have neither of these things, nor do they need them.

Most people with RO systems are amazed by the taste of their water, stating that it tastes even better than most bottled water. They not only drink more water, they even use their RO water for coffee, tea, and cooking.

If you properly maintain your system, it lasts practically forever. Replace your filters and the membrane as needed, as well as any parts that wear out, and your system keeps running.

Installation generally takes about an hour. If you also require lines to your refrigerator, this takes slightly longer.

The installation price for Isley’s Home Service’s RO systems ranges between $500 and $600. We carry the Ultima 7, manufactured by Gilbert’s own B&R Industries. Thanks to local access, obtaining replacement parts and filters is a breeze. Call 480-736-1805 to learn more.

Yes, it will. In fact, a water softener likely extends the life of your RO membrane, since it removes calcium and magnesium from the water, which are two of the more challenging minerals for the membrane to remove.

Isley’s recommends the Ultima water softeners, which range in price from around $1,100 to around $1,500. If you’re interested in installing both systems, talk to one of our experts to discover which water softener will best meet your needs.

A reverse osmosis system removes many contaminants from your drinking water. Many harmful ions and metals are removed, as well as particles and pesticides. Some of the contaminants removed are arsenic, chloride, and lead. The particles removed are Asbestos, Protozoan cysts, and Cryptosporidium. Reverse Osmosis will also remove pesticides if present in your water like Endrin, Heptachlor, Lindane, and Pentachlorophenol. The table below shows a more comprehensive list of all of the contaminants removed by a reverse osmosis system.
