Reverse Osmosis Installation in Goodyear, AZ

A water softener removes calcium and magnesium from water through ion exchange, replacing them with sodium. This addresses hardness — the specific minerals that cause scale, reduce soap effectiveness, and shorten appliance life. A reverse osmosis system pushes water through a semi-permeable membrane under pressure, removing a broad spectrum of dissolved substances including minerals, chlorine, chloramines, nitrates, arsenic, and many other compounds. The softener treats all the water entering your home. The RO system treats water at a single point, typically the kitchen sink, for drinking and cooking. The two systems complement each other: a softener extends RO membrane life; the RO produces drinking water quality the softener cannot.

A standard under-sink RO system has three to five filtration stages. Water from the cold supply passes first through a sediment filter that captures particles. A pre-carbon filter then removes chlorine and chloramines that would damage the membrane. The water then passes under pressure through the RO membrane, which allows water molecules through but blocks dissolved minerals, heavy metals, and other substances. A post-carbon filter polishes the water before it reaches the dedicated faucet. The filtered water is stored in a small pressurized tank under the sink so it is available on demand. Rejected concentrate water exits through the drain line.

In Goodyear without a water softener: the sediment pre-filter every 6 months, the carbon pre-filter every 6 months, and the RO membrane every 12 to 18 months. With a whole-home softener upstream of the RO system, pre-filter life extends to 12 months and membrane life to 2 to 4 years. The post-carbon polishing filter is replaced at the same time as the membrane. We service all major RO brands including Aquasana, iSpring, Express Water, and others, and we can set up a maintenance schedule so filter replacement is not missed.

Yes. Most under-sink RO systems can supply a refrigerator's water and ice dispenser with a dedicated small-diameter line run from the RO storage tank to the refrigerator connection. The water quality improvement for ice is noticeable — ice from RO water is clearer and cleaner tasting than ice from untreated tap water. The refrigerator connection does reduce the RO storage tank pressure somewhat, and homes with high refrigerator usage may benefit from a larger-capacity tank or a tankless RO system with higher flow rates. We assess the capacity requirement during the installation estimate.

RO filtration does remove minerals from water, including calcium and magnesium along with the dissolved minerals that contribute to water's taste. The health concern about mineral removal from drinking water is addressed in the literature: the mineral contribution of drinking water to daily dietary intake is small relative to food sources. Remineralization filters, which add back controlled amounts of calcium and magnesium, are available as a final stage option for homeowners who prefer mineral content in their drinking water. We discuss filter stage options during the installation consultation and can include remineralization if desired.
