Aqua Pure Plumbing warns hard water is cutting water heater life in DFW

Aqua Pure Plumbing says mineral-heavy water from Lewisville Lake is accelerating sediment buildup, corrosion and scale in water heaters across The Colony, Frisco, Plano and nearby suburbs. The company is urging annual flushing and routine maintenance as homeowners face earlier failures in both tank and tankless units.

Why it matters: - Hard water is shortening the life of water heaters across northern Dallas suburbs, raising repair and replacement costs for homeowners. - The problem affects both traditional tank units and tankless systems, which can fail early without routine maintenance. - Aqua Pure Plumbing says the issue is especially relevant in communities served by Lewisville Lake and the Upper Trinity Regional Water District.

What happened: - Aqua Pure Plumbing identified hard water as a leading cause of early water heater failure in The Colony, Frisco, Plano, Carrollton and surrounding DFW suburbs. - The company says Lewisville Lake water carries mineral content that accelerates sediment buildup, corrodes anode rods and damages heating components. - Water hardness in the affected DFW suburbs ranges from about 10 to 21 grains per gallon, depending on municipality and season. - The U.S. Geological Survey classifies anything above 10.5 grains per gallon as very hard.

The details: - Calcium and magnesium in hard water coat heating elements, settle as sediment in tank water heaters and scale heat exchangers in tankless units. - Devan Adair, owner and master plumber at Aqua Pure Plumbing, said many removed water heaters from Colony and Carrollton homes are only six to eight years old and contain two to three inches of sediment. - Adair said anode rods are often fully depleted by that point, allowing tank corrosion to begin and leading to rust-colored water or leaks. - Anode rods are designed to sacrifice themselves so the steel tank does not corrode. - In softer water, an anode rod can protect a tank for three to five years. - Industry data indicates a well-maintained water heater typically lasts eight to 12 years under normal conditions. - Plumbing trade sources say hard water can reduce that lifespan by about two years. - Aqua Pure Plumbing recommends flushing tank water heaters at least once a year and inspecting anode rods every two to three years in DFW, faster than the interval common in softer-water regions. - Tankless water heaters need annual descaling because scale buildup can restrict flow, trigger error codes and void the manufacturer’s warranty. - Aqua Pure Plumbing says many tankless units serviced in Allen, Frisco and McKinney are only three or four years into a 10-year warranty but already show severe scale buildup because annual maintenance was skipped. - Every water heater installation by the company includes a code-compliant thermal expansion tank, a drain pan on elevated or closet installs, correct temperature and pressure relief discharge routing and dielectric unions on supply connections. - The company holds active plumbing licenses across multiple DFW municipalities and says it has a BuildZoom score of 97, placing it in the top 18% of more than 222,000 Texas licensed contractors. - Aqua Pure Plumbing serves homeowners in 14 DFW cities: The Colony, Frisco, Plano, McKinney, Allen, Carrollton, Lewisville, Flower Mound, Highland Village, Lake Dallas, Coppell, Farmers Branch, Richardson and Addison.

Between the lines: - The warning points to a maintenance gap, not just a water-quality issue. - Homeowners in hard-water areas may see premature failure even when water heaters are otherwise standard residential models. - The company is positioning annual flushing and anode-rod checks as low-cost steps that may prevent much larger replacement expenses.

What's next: - Aqua Pure Plumbing is likely to keep pushing routine maintenance for tank and tankless systems across the northern Dallas metro. - Homeowners in the affected suburbs may need to shorten service intervals if they want to preserve manufacturer coverage and extend equipment life. - The company says it offers same-day and after-hours service across its service area.

The bottom line: - In DFW suburbs fed by Lewisville Lake water, hard water is not just an inconvenience. It is a major factor in water heater wear, corrosion and early failure.
