Key Largo Water Treatment Systems
Partnered with Penguin Water to Bring Better Water to Customers Throughout South Florida, Including the Upper Keys, Homestead, and Miami
Seaway Plumbing has partnered with Penguin Water to bring the Florida Keys' most advanced water treatment solutions directly to your home or business. This exclusive partnership combines our two decades of local plumbing expertise with Penguin Water's cutting-edge filtration technology, creating customized water treatment systems that address the unique challenges of South Florida's water supply.
Seaway Plumbing and Penguin Water can protect your water supply from:
- Hard water. Calcium and magnesium minerals cause scale buildup on fixtures, reduce soap efficiency, and lead to premature appliance failure throughout your home.
- Iron contamination. High iron levels create metallic tastes, rust-colored stains on fixtures and laundry, and unsightly discoloration in your water supply.
- Sulfur odors. Hydrogen sulfide gas produces an unpleasant "rotten egg" smell that affects the taste of water and creates an uncomfortable living environment.
- Sediment and particles. Sand, dirt, and debris particles can clog fixtures, damage appliances, and create cloudy or gritty water throughout your property.
- Acidic water. Low pH levels corrode pipes and plumbing fixtures while creating unpleasant metallic tastes and potential health concerns.
- Chlorine and chloramines. Municipal water treatment chemicals can affect taste and odor while potentially causing skin and eye irritation during bathing.
- Microorganisms. Bacteria, viruses, and other harmful pathogens present serious health risks and can cause waterborne illnesses in your family.
- PFAS and PFOS. These emerging "forever chemicals" are linked to serious health concerns and require specialized advanced filtration systems for effective removal.
Whether you're dealing with one specific issue or multiple water quality challenges common in coastal areas, our treatment solutions deliver clean, great-tasting water that protects your plumbing fixtures and enhances your daily life.

Reverse Osmosis Systems for Every Application
Penguin Water’s reverse osmosis systems represent the gold standard in water purification, utilizing advanced membrane technology to remove up to 99% of contaminants while delivering crystal-clear, great-tasting water throughout your property. Whole-home reverse osmosis systems provide comprehensive water treatment for every faucet, shower, and appliance, protecting your entire plumbing system from mineral buildup while giving you the confidence that comes with knowing your family has access to premium water quality throughout your home. These systems are particularly beneficial in the Florida Keys, where mineral-rich water can cause accelerated wear on fixtures and appliances.
For targeted water improvement, our under-counter reverse osmosis systems deliver exceptional water quality directly at your kitchen sink, providing convenient access to purified water for drinking, cooking, and food preparation without the ongoing cost of bottled water. We also offer commercial reverse osmosis systems that are designed to meet the demanding needs of restaurants, hotels, and businesses throughout Key Largo and the Florida Keys, providing consistent water quality that protects equipment, improves food and beverage taste, and helps maintain customer satisfaction while reducing operational costs.




Water Systems for Every Preference
Beyond reverse osmosis, Seaway Plumbing and Penguin Water offer a complete range of water treatment technologies designed to address specific water quality challenges common in South Florida's coastal environment. Each system is carefully selected and professionally installed for optimal performance and long-term reliability.
Our advanced water systems include:
- UV disinfection systems. Ultraviolet light technology can eliminate bacteria, viruses, and other microorganisms without adding chemicals to your water supply, providing safe, clean water that maintains its natural taste.
- Water softeners. Ion exchange technology can remove calcium and magnesium minerals that cause hard water problems, protecting your plumbing fixtures and appliances while improving soap efficiency and reducing mineral spotting.
- Water conditioners. Our advanced conditioning systems can alter mineral structure to reduce scale buildup and corrosion without removing beneficial minerals, providing gentler water treatment for sensitive applications.
- Salt-free systems. We offer environmentally friendly alternatives to traditional softeners that prevent scale formation without adding sodium to your water supply, which is ideal for customers with dietary restrictions or environmental concerns.
- Combination systems. Our multi-stage treatment solutions integrate multiple technologies to address complex water quality issues, providing comprehensive treatment in a single, space-efficient unit.
Our team works closely with each customer to identify the most effective treatment approach based on detailed water analysis, usage patterns, and specific quality goals.
