Reverse Osmosis Systems
The water from your tap might look clean, but appearances can be deceiving. Chlorine, lead, PFAS, and other contaminants can be present without changing how your water looks. A reverse osmosis system provides the highest level of drinking water purification available for homes in Venice Florida.
Legend Plumbing specializes in professional reverse osmosis system installation. We help Venice Florida homeowners enjoy pure, great-tasting water straight from their kitchen tap—without the expense and waste of bottled water. As part of our comprehensive Water Quality Services, we ensure your drinking water is as pure as possible.
What Is Reverse Osmosis?
Reverse osmosis is a water purification process that removes contaminants by pushing water through a semi-permeable membrane. Think of it as a microscopic filter that catches particles too small to see.
Here’s what makes reverse osmosis different from other filtration:
Particle Size Matters
A standard water filter catches sediment and chlorine. But many contaminants are much smaller. Reverse osmosis membranes have pores around 0.0001 microns. That’s smaller than a virus. Smaller than bacteria. Small enough to catch contaminants that other filters miss.
The Process
Water pressure forces water through the membrane. Contaminants are trapped on one side and flushed away. Pure water passes through to a storage tank, ready for drinking. The result is water that’s as pure as what you’d get from a commercial bottling plant.
What RO Removes
Reverse osmosis systems remove:
-
Chlorine and chloramines – For better taste and odor
-
Lead and heavy metals – Protecting your family’s health
-
PFAS (forever chemicals) – [VERIFY PFAS REMOVAL CLAIMS]
-
Nitrates and nitrites – Common in some water supplies
-
Arsenic – A concern in some areas
-
Bacteria and viruses – [VERIFY IF RO REMOVES BACTERIA]
-
Dissolved solids – Improving taste and clarity
-
Pharmaceutical residues – Trace amounts found in water supplies
What RO Doesn’t Remove
Reverse osmosis removes a lot, but not everything:
-
Some volatile organic compounds (VOCs) – May need additional carbon filtration
-
Chlorine – RO membranes can be damaged by chlorine, so systems include carbon pre-filters
-
Some pesticides and herbicides – Carbon filters typically handle these
Most RO systems include multiple stages of filtration, including carbon filters, to handle these limitations.
Why Venice Florida Homeowners Choose Reverse Osmosis
Better Taste
Chlorine, minerals, and other contaminants affect how water tastes. RO removes them, delivering clean, crisp water that tastes like it should. You’ll notice the difference in drinking water, coffee, tea, and even ice cubes.
Healthier Water
RO removes many contaminants that can affect health over time. Lead, PFAS, arsenic, and other substances have been linked to health concerns. RO provides peace of mind for families concerned about their water quality.
Cost Savings
The average family spends hundreds of dollars annually on bottled water. An RO system provides unlimited purified water for a fraction of the cost. The system pays for itself over time while eliminating plastic waste.
Convenience
No more carrying heavy water bottles from the store. No more recycling piles of plastic. Great-tasting water is always available right from your tap.
Environmental Impact
Plastic water bottles are a major environmental problem. RO systems significantly reduce plastic waste by replacing bottled water with purified tap water.
How Reverse Osmosis Compares to Other Options
| Filtration Type | What It Removes | Best For |
|---|---|---|
| Reverse Osmosis | Heavy metals, PFAS, dissolved solids, chlorine | Highest purity drinking water |
| Carbon Filter | Chlorine, sediment, some chemicals | General taste and odor improvement |
| Water Softener | Calcium, magnesium | Hard water problems |
| Whole-Home Filter | Chlorine, sediment, some contaminants | Overall household water quality |
| Distillation | Most contaminants | Very high purity, but slow and energy-intensive |
Reverse osmosis provides the highest level of purity for drinking water. Many homeowners combine RO with a water softener or whole-home filter for complete water quality. Explore our Water Softener Installation and Whole Home Water Filtration pages for additional solutions.
The RO System Components
A typical reverse osmosis system has several key parts:
Pre-Filters
Water passes through carbon and sediment pre-filters before reaching the membrane. These remove chlorine (which can damage the membrane) and larger particles.
The Membrane
This is the heart of the system. The semi-permeable membrane catches contaminants while allowing water to pass through.
Post-Filter
After the membrane, water passes through a final carbon filter that improves taste before reaching your tap.
Storage Tank
RO systems produce water slowly. The storage tank holds purified water so it’s available when you need it.
Faucet
RO systems typically include a dedicated faucet installed on your kitchen sink. The faucet delivers purified water separate from your regular tap.
Drain Line
Contaminants removed by the membrane are flushed away through a drain line.

Maintenance and Filter Changes
Filter Replacement
Pre-filters and post-filters typically need replacement every 6-12 months. The RO membrane lasts 2-5 years depending on water quality and usage.
Sanitization
Systems should be sanitized periodically to prevent bacterial growth. [VERIFY SANITIZATION RECOMMENDATIONS]
Tank Maintenance
The storage tank may need air pressure adjustments over time to maintain proper flow.

Common Questions About Reverse Osmosis
Is reverse osmosis water safe to drink?
Yes. RO water is safe and healthy. The process removes contaminants while leaving water that is pure and refreshing. RO water is similar to distilled water in purity.
Does reverse osmosis remove beneficial minerals?
RO removes minerals, both good and bad. However, the minerals removed are not essential for health. You get plenty of minerals from food. Many people prefer the pure taste of RO water.
Is RO water acidic?
RO water can be slightly acidic because it lacks buffering minerals. This is normal and not a health concern. Some systems include a remineralization filter to add minerals back if desired.
How much water does RO waste?
Older RO systems waste 3-4 gallons for every gallon of purified water. Modern systems are much more efficient. [VERIFY WASTE RATIO] The waste water is used to flush contaminants away.
How much does an RO system cost?
Costs vary based on the system and installation complexity. Contact us for a customized quote. Most homeowners find RO systems pay for themselves compared to bottled water costs.
How long does installation take?
Most RO installations take a few hours. We provide a specific timeline during your consultation.
Will RO work with my existing plumbing?
RO systems can be installed under most kitchen sinks. We evaluate your space during the consultation to ensure compatibility.
