Why Bismarck Homeowners Are Choosing Reverse Osmosis

If you’ve ever wondered whether the water coming out of your kitchen faucet is as clean as it could be, you’re not alone. Many homeowners across Bismarck, Mandan, Lincoln, Wilton, and surrounding communities in Burleigh and Morton Counties want better-tasting, higher-quality drinking water without relying on bottled water. A reverse osmosis system gives you that, right from your tap.

We handle RO system installation, RO maintenance, and RO filter replacement for residential properties throughout central North Dakota. Whether you want an under-sink reverse osmosis unit for your kitchen or a whole house RO system that treats every faucet in your home, we’ll help you choose the right clean drinking water system for your household and install it properly.

According to the EPA, point-of-use reverse osmosis systems can remove contaminants such as lead, arsenic, PFAS, volatile organic compounds, bacteria, and viruses from drinking water. RO works by forcing water through a semi-permeable membrane that blocks dissolved solids and impurities while allowing clean water to pass through. It’s one of the most effective drinking water filtration technologies available to homeowners.

Signs You Could Benefit From an RO System

Water Tastes or Smells Like Chlorine

Municipal water in the Bismarck-Mandan area is treated with chlorine for safety, but that treatment leaves a taste and smell many homeowners find unpleasant. An RO system removes chlorine and its byproducts, giving you water that tastes clean and neutral.

You're Buying Bottled Water Regularly

If you’re spending money on bottled water or filling jugs from a store dispenser, a reverse osmosis system pays for itself over time. You get the same quality (often better) directly from your kitchen faucet without the plastic waste or recurring cost.

Concerns About Lead, PFAS, or Other Contaminants

Older plumbing, aging municipal infrastructure, and well water sources can introduce contaminants into your drinking water. RO systems are one of the most effective household methods for reducing lead, PFAS (forever chemicals), arsenic, nitrates, and other dissolved impurities.

Hard Water Residue on Dishes and Fixtures

While a water softener handles whole-house hardness, adding a reverse osmosis system at the kitchen sink gives you mineral-free drinking and cooking water. White spots on dishes, cloudy ice cubes, and chalky residue on pots are signs your water has high mineral content.

You Have Well Water

Homes on private wells in Baldwin, Wilton, and rural areas of Burleigh and Morton Counties don’t receive treated municipal water. A reverse osmosis system provides an additional layer of filtration to catch dissolved minerals, bacteria, and naturally occurring contaminants that well water often carries.

Your Current Filter Isn't Cutting It

Pitcher filters and basic faucet attachments improve taste, but they don’t remove dissolved solids, heavy metals, or chemical contaminants the way a reverse osmosis membrane does. If you want what is the best water filtration system for your home, RO is the answer for drinking water quality.

RO System Services We Provide

The most popular option for homeowners who want clean drinking water at one location. An under-sink reverse osmosis system installs below your kitchen sink and connects to a dedicated faucet. It filters water through multiple stages including sediment removal, carbon filtration, and the RO membrane. We handle the full installation including a dedicated tap, storage tank, and drain connection.

For homeowners who want filtered water at every tap, a whole house RO system treats all the water entering your home. This is a larger installation that requires proper sizing based on your household’s daily water usage. We assess your home, recommend the right system, and handle the complete installation.

Like any filtration system, an RO unit needs regular RO maintenance to perform at its best. We inspect the system, check for leaks, test water quality before and after the membrane, and ensure all stages are functioning. Annual maintenance keeps your system running efficiently and your water clean.

RO systems have multiple filter stages that need periodic replacement. Sediment and carbon pre-filters typically need replacing every 6 to 12 months. The RO membrane lasts 2 to 3 years depending on usage and water quality. We handle RO filter replacement for all major brands and make sure every stage is working properly.

If your current system is outdated, underperforming, or you want to upgrade from a basic unit to a higher-capacity model, we remove the old system and install the new one. We also upgrade single-stage filters to full multi-stage RO systems for homeowners ready to make the switch.

Reverse Osmosis vs Whole Home Filter: Which Do You Need?

One of the most common questions we get is: reverse osmosis vs whole home filter, which one is right for me? The answer depends on what problem you’re trying to solve.

Under-Sink Reverse Osmosis:

Best for drinking and cooking water quality
Removes dissolved solids, heavy metals, PFAS, chlorine, and more
Installed at one faucet (usually the kitchen)
Produces water through a dedicated tap
Requires filter and membrane changes on a regular schedule

Whole Home Water Filter / Softener:

Best for protecting plumbing, appliances, and fixtures
Removes sediment, chlorine taste, and mineral hardness
Treats all water entering the home
Does not remove dissolved contaminants like lead, PFAS, or nitrates
Requires periodic media or salt replacement

For most Bismarck-area homeowners, the best setup is both: a whole-house water softener or carbon filter to protect your plumbing and appliances, paired with an under-sink reverse osmosis system for the water your family actually drinks and cooks with. We install both systems and can design a clean drinking water system that covers your whole home. Is RO system worth it? For the quality of water it delivers, absolutely.

Our Awesome Reviews

Alicia Wehri

If you’re looking for someone super professional, does the job right, and very timely, I’d highly recommend Premium Plumbing & Rooter. I had Joe out for the first time on a sewer-related emergency, resulting in the need to replace 10 feet of sewer line this past week, and I was highly impressed. The guy really does it all, and does it very well. Keep it up!

While a plumbing emergency is never fun, Premium Plumbing got here quick and did a great job dealing with the crisis. It was a pleasure to watch people that know their trade and I’ll definitely use them again if I have another plumbing issue. Reasonably priced too.

If I could give higher than five stars I would! Joe and his team were absolutely wonderful to work with. They were able to fix decades worth of corrosion to the plumbing in our home. Their work was done with a level of artistry I’ve never experienced with a plumber before. Joe was able to give us more space in our laundry room by simplifying and correcting existing plumbing. Once the project was completed they thoroughly explained all that was done as well as how the work will aid future projects.  An added bonus, they cleaned up after themselves, were respectful of the property and were extremely conscientious of the pets.

Reverse Osmosis Questions

What is the best water filtration system for my home?

For drinking water quality, a reverse osmosis system is the most effective option available to homeowners. It removes dissolved solids, heavy metals, and chemical contaminants that basic carbon filters and pitcher filters can’t touch. For whole-house protection against hardness and sediment, pair it with a softener or whole-home filter.

How much does an RO system cost?

How much does RO system cost depends on whether you choose an under-sink unit or a whole house RO system, the number of filtration stages, and any additional plumbing work needed. We provide up-front pricing after assessing your home. Call (701) 805-9911 for a free estimate.

Is an RO system worth it?

Is RO system worth it? Yes, especially if you’re concerned about water quality, tired of buying bottled water, or on well water. RO systems deliver cleaner, better-tasting water at a fraction of the long-term cost of bottled alternatives. Most homeowners see a return on their investment within the first year.

How often do RO filters need to be replaced?

Pre-filters (sediment and carbon) should be replaced every 6 to 12 months. The RO membrane typically lasts 2 to 3 years. Post-filters are replaced annually. We offer RO maintenance and RO filter replacement service to keep your system performing at its best.

Can you install an RO system if I already have a water softener?

Yes. In fact, pairing a softener with an RO system is the ideal setup. The softener handles hardness and protects your plumbing, while the RO system delivers the cleanest possible drinking water at your kitchen tap. We install both and connect them to work together.
