The Truth About Reverse Osmosis Systems: Pros, Cons, and Myths

Homeowners often hear about reverse osmosis systems when considering ways to improve drinking water. Trident Plumbing & Drain provides clarity on what these systems actually do, what they cannot do, and how they compare to other options. For those weighing upgrades to water filtration in Peoria, AZ, understanding the real advantages and limitations can help make the decision easier.

What Are Reverse Osmosis Systems?

Reverse osmosis systems force water through a semi-permeable membrane under pressure, removing contaminants as small as 0.0001 microns. This process eliminates bacteria, viruses, heavy metals, chlorine, and dissolved solids that other filtration methods might miss. The system typically includes pre-filters, the RO membrane, and a storage tank that holds purified water.

Benefits of Reverse Osmosis Systems

A reverse osmosis system provides several advantages for homeowners concerned about water quality. The technology removes up to 99% of dissolved minerals, chemicals, and contaminants, including lead, arsenic, fluoride, and nitrates. This level of purification surpasses most standard water filtration system options available today.

The taste improvement is immediate and noticeable. Filtered water can taste cleaner and fresher, without the chlorine odor common in municipal water supplies. For families with health concerns or compromised immune systems, RO systems provide an extra layer of protection against waterborne contaminants.

Drawbacks and Limitations

Reverse osmosis systems require regular maintenance to function properly. Filters need replacement every 6-12 months, and the RO membrane typically lasts 2-3 years. Professional water treatment services help maintain optimal performance, but homeowners must budget for ongoing maintenance costs.

Water waste is a significant concern. Traditional RO systems produce 3-4 gallons of wastewater for every gallon of purified water. Modern high-efficiency models reduce this ratio, but waste remains higher than in other filtration methods. This inefficiency can impact water bills and environmental consciousness.

It is also important to note that while RO systems remove many harmful contaminants, they also strip away beneficial minerals like calcium and magnesium, which some people prefer to keep in their water. Additionally, the slow filtration rate means filling large containers takes considerable time.

Debunking Common Myths

Myth 1: An RO system makes water too acidic.

Fact: The slight change in pH is not enough to pose a health risk. The human body is designed to regulate its pH, and the change is minimal.

Myth 2: My existing water softener is enough; I do not need an RO system.

Fact: A water softener removes hardness minerals like calcium and magnesium, but does not purify the water or remove contaminants such as lead or chlorine. A water softener and a reverse osmosis system perform different functions.

Myth 3: An RO system removes all bacteria and viruses.

Fact: While the RO membrane is effective at blocking many microorganisms, it is not a complete solution for microbiological contaminants. For high levels of bacteria or viruses, a UV light treatment or another method may be required.

When to Consider RO Installation

Homeowners should consider reverse osmosis systems when dealing with specific water quality issues. High levels of dissolved solids, heavy metals, or chemical contamination make RO an excellent choice. Areas with poor municipal water quality or well water problems often benefit from comprehensive filtration.

Families with health concerns, infants, or elderly members may find peace of mind with RO systems. The technology provides consistent water quality regardless of seasonal changes or municipal treatment variations that can affect taste and safety.

Whole home water filtration represents another option, though it typically costs more and requires professional installation throughout the house plumbing system.
