Services
Residential Water Softeners
Our residential water softeners eliminate hardness minerals that cause scale buildup and soap scum. High-efficiency models minimize salt consumption while extending appliance lifespan. Systems include Windsor Series Hi-Cap and Hi-Efficiency options designed for different water hardness levels. These solutions improve water quality for household tasks while reducing maintenance costs associated with hard water damage.
Commercial Water Systems
Commercial water conditioning systems address hardness challenges in business environments. The Windsor Series 125-200 and 3900 Series provide scalable solutions for institutional applications. These systems reduce maintenance costs by preventing scale buildup in plumbing and equipment. Designed for durability, they ensure consistent water quality in commercial operations while maintaining regulatory compliance.
Iron Filtration
Iron filtration systems remove nuisance iron through oxidation and filtration processes. The Eliminator III system addresses iron-related staining and taste issues. Catalytic filters target hydrogen sulfide to eliminate rotten egg odors. These solutions provide clean water for both residential and commercial applications while protecting plumbing infrastructure from corrosion.
Reverse Osmosis
Reverse osmosis systems deliver purified drinking water through multi-stage filtration. The Microline system uses semipermeable membranes to reduce dissolved solids and impurities. TFC435 and TFC300 models offer four- and three-stage filtration with optional water quality monitoring. These systems provide clean, great-tasting water while minimizing waste through efficient operation.
Carbon Filtration
Carbon filtration systems reduce chlorine taste and odor in municipal water supplies. Windsor Series Carbon Filters use activated carbon media to produce clean, fresh water. These systems address common aesthetic water quality issues while maintaining flow efficiency. Ideal for households and businesses seeking improved water taste without compromising pressure.
