Choosing the right water treatment service begins with knowing your home's water quality, which is why we offer free in-home water testing throughout the Charlotte area. For more than 20 years, we have helped protect families from hard water, contaminants, and impurities with professional water filtration solutions and straightforward advice. Our services range from whole-house filtration and comprehensive water treatment to water softeners, UV water purification, and iron filtration systems. Whole-home filtration provides cleaner water from every tap, while water softeners address hard-water buildup and scale. UV purification provides advanced protection against microorganisms, and iron filtration addresses staining and taste issues. We also help homeowners consider concerns related to Charlotte water contaminants, PFAS, Lake Norman-area well water containing iron and bacteria, and chlorine taste and odor from municipal treatment.Our owner and lead technician, Frank Helms, has more than two decades of experience and began his career as a school plumber in Mecklenburg. As a Charlotte native, he has developed a detailed understanding of local water conditions and the challenges homeowners face. We are independently operated rather than part of a franchise, and we do not rely on hidden fees or pressure sales. Instead, we provide honest, upfront recommendations focused on clean, safe water for your family's health and wellness. Our service area covers the Greater Charlotte region, including Gastonia, Lake Norman, Concord, and Matthews. We are licensed in North Carolina and coordinate South Carolina installations with local licensed plumbers. Our free testing carries no obligation, and our services are backed by a satisfaction guarantee.

Knowing what is actually in your water can make decisions about water treatment more informed. We offer residential testing at no cost and use the results to identify concerns such as hardness, contamination, bacteria, or other water-quality issues. The on-site process generally takes 30 to 45 minutes. We discuss the findings and answer your questions before you consider a solution. 
When homeowners want to improve the taste or quality of their drinking water, we offer reverse osmosis as a focused solution. The process forces water through a specialized membrane created to reduce numerous unwanted contaminants. Installed at the kitchen sink, the system provides consistent treatment for water used throughout daily routines, including drinking, cooking, coffee, ice, and food preparation. 
We install water softeners to help reduce the minerals that create common hard-water inconveniences. Customers may experience cleaner fixtures, better soap performance, improved showers, and less troublesome laundry after addressing the mineral content. The service also supports the long-term condition of plumbing, appliances, and water heaters by reducing buildup and unnecessary strain caused by hard water. 
We provide whole-house water filtration to improve water quality throughout your home rather than at a single faucet or appliance. Our process begins with a free in-home water test to identify what is in your water. We then recommend an appropriate system, provide upfront pricing, and complete professional installation with minimal disruption. 
Ultraviolet light water purification gives homeowners an additional approach to protecting their water supply. By using UV light to disrupt microorganisms, the system focuses on biological contaminants that standard filters may not address. We consider this service particularly meaningful when bacteria are a concern, including with well water or changing water conditions. UV purification can also serve a distinct role within a broader treatment plan.

Frank Helms
Owner
At Frank Water Systems, we believe better water can make a real difference in the way you live at home. Water affects more than what comes out of the tap. It affects taste, comfort, daily routines, and the overall feel of your home. That is why we built this company around a simple idea: give people honest answers, quality work, and water solutions that genuinely improve everyday life.
