What Is a Reverse Osmosis System and Should I Install One?

If you have ever noticed an odd taste or smell in your tap water, you are not alone. Many homeowners in Minnesota deal with water quality issues every day. A reverse osmosis system is one of the most effective ways to improve your drinking water at home. But before you decide, it helps to understand exactly what it does and whether it makes sense for your situation.

Key Takeaways

• A reverse osmosis system filters water by pushing it through a semipermeable membrane.
• It removes contaminants like lead, chlorine, nitrates, and dissolved solids.
• Most systems are installed under the kitchen sink and connect to a dedicated faucet.
• RO systems work well in Minnesota where hard water and dissolved minerals are common.
• Brass Tacks Plumbing installs reverse osmosis systems for homeowners across the West Metro Twin Cities.
• Regular filter maintenance keeps the system working properly over time.

How a Reverse Osmosis System Works

A reverse osmosis system, often called an RO system, uses pressure to push water through a very fine membrane. That membrane has pores small enough to block most contaminants. The clean water passes through and collects in a storage tank. The contaminants get flushed away as wastewater.

Most home RO systems include multiple filter stages. Each stage targets different types of impurities. Together, they remove a wide range of unwanted substances from your water before it reaches your glass.

What Does a Reverse Osmosis System Remove?

RO systems are very thorough. They can remove up to 99% of many common contaminants. This includes lead, chlorine, fluoride, nitrates, arsenic, sediment, and dissolved solids. Some systems also reduce certain bacteria and viruses, depending on the filter configuration.

In Minnesota, dissolved minerals are a real concern. Hard water leaves scale inside your pipes, fixtures, and appliances. While a water softener handles hardness minerals like calcium and magnesium, an RO system goes further by removing additional impurities that affect taste and safety. Many homeowners use both systems together for complete water quality coverage.

Where Is a Reverse Osmosis System Installed?

Most residential RO systems are installed under the kitchen sink. The system connects to your cold water line and runs to a small dedicated faucet on your counter or sink. A storage tank sits underneath the sink and holds filtered water so it is ready when you need it.

The reverse osmosis system installation process involves connecting supply lines, mounting the faucet, and securing the storage tank. It typically requires some basic plumbing work. A licensed plumber can complete the job cleanly and make sure everything is connected correctly the first time.

Can It Connect to My Refrigerator or Ice Maker?

Yes. Many homeowners connect their RO system to their refrigerator’s water line and ice maker. This gives you filtered water and ice throughout the kitchen. The connection requires a simple line from the RO system to the fridge. A plumber can route that line during installation so everything stays tidy inside your cabinets.

Brass Tacks Plumbing handles these installations for homeowners in Plymouth, Wayzata, Minnetonka, Maple Grove, and surrounding West Metro communities. If you want filtered water from every source in your kitchen, this setup is worth considering.

Is a Reverse Osmosis System Right for Your Home?

An RO system is a good fit for most homes. It is especially useful if your water has a noticeable taste or odor, if you have older plumbing that may leach lead, or if your local water report shows elevated levels of nitrates or other contaminants. It is also a smart choice if you currently buy bottled water regularly.

Switching to an RO system can save money over time compared to buying bottled water. You also reduce plastic waste. The water quality you get from a properly maintained RO system is often better than what you get from store-bought bottles.

What Are the Limitations?

RO systems do have a few trade-offs. They produce some wastewater during the filtration process. Older systems could use three to five gallons of water for every one gallon filtered, though newer models are much more efficient. The system also removes some beneficial minerals like calcium and magnesium along with the harmful ones.

Filters need to be replaced on a regular schedule, usually every six to twelve months depending on use and water quality. Skipping filter changes reduces performance and can allow contaminants to pass through. Staying on schedule is simple and keeps your water consistently clean.

Frequently Asked Questions

How long does a reverse osmosis system last?

A well-maintained RO system can last ten to fifteen years or more. The membrane itself usually needs replacement every two to three years. Pre-filters and post-filters require more frequent changes, typically every six to twelve months. Keeping up with maintenance extends the life of the entire system.

Does a reverse osmosis system need a lot of water pressure to work?

RO systems work best with water pressure between 40 and 80 PSI. If your home has low water pressure, the system may produce water more slowly or less efficiently. A plumber can check your home’s pressure and recommend a booster pump if needed.

Will a reverse osmosis system work with a water softener?

Yes, and many homeowners use both together. The water softener handles hardness minerals throughout the whole house. The RO system then provides an extra level of filtration for drinking and cooking water at the kitchen sink. The two systems complement each other well.

Is the water from an RO system safe to drink every day?

Yes. Reverse osmosis water is safe for daily drinking. Some people add a remineralization filter to put beneficial minerals back into the water after filtration. This is optional, but it can improve the taste and add back calcium and magnesium that were removed during the process.

How do I know if my water needs an RO system?

You can start by requesting a copy of your local water quality report, also called a Consumer Confidence Report. Your water utility is required to provide this annually. If the report shows elevated contaminants, or if your water tastes or smells off, an RO system is worth looking into. A plumber can also help you assess your specific situation.
