Homeowners in San Antonio and surrounding areas are facing a hidden but costly problem: extremely hard water. In the September 14, 2026 episode of The Building Texas Show, titled “The Hidden Damage Hard Water Is Doing to Your Home Right Now,” host Justin McKenzie speaks with Jason Stevenson of Kinetico about the science and economics of hard water in South Texas. The conversation, recorded at the San Antonio Home and Garden Show at the Alamodome, highlights why this issue matters for the tens of thousands of new Texas homeowners, many from California, Colorado, and northern states, who are discovering that local water is punishing their skin, hair, appliances, and bank accounts.
Stevenson explains that San Antonio water tests between 10 and 32 grains hard, while parts of Helotes run 50 to 150 grains. He notes that the San Antonio Water System adds fluoride and chlorine to control pipe buildup, which affects what comes out of the tap. The fine print on tankless water heaters often voids warranties above 10 grains of hardness, a critical detail for homeowners considering such systems. Without a water softener, Stevenson says, “your dishwasher lifespan is reduced by close to 70%,” because the heating element captures calcified minerals from the aquifer’s limestone. He advises new buyers to check glass shower doors and stovetops within two to three weeks of moving in: “If you see that white residue either on the glass door or around that pot and pan, then you know you have some very hard water over there.” In the hardest zones, shower fixtures can wear out twice a year.
The episode also delves into Kinetico’s engineering and Texas footprint. Stevenson describes the company’s dual resin tank plus carbon tank design, which uses soft water to regenerate and can last more than 20 years, with warranties that transfer to new homeowners by serial number—a rarity in the industry. On sustainability, Kinetico regenerates on roughly 11 gallons of water versus 62 to 92 gallons for competing systems, a point Stevenson ties directly to Texas water scarcity and the surge of data center demand. Commercial customers, including hotels, schools, churches, and San Antonio fire stations, have reduced detergent use by more than half after installation.
Pricing for Kinetico systems ranges from $3,200 to $7,500, with 12 months interest-free financing and military and first responder discounts. The discussion provides practical guidance for homeowners navigating the challenges of hard water, from protecting appliances to understanding warranty implications.
