Is now a good time for you to invest in a home water softening system?
SoftPro Water Systems has issued guidance for San Antonio households to address local water hardness levels that measure 15.2 grains per gallon. Residents are advised to consider salt-based ion exchange systems to effectively manage mineral deposits caused by the region's limestone bedrock.
Why it matters
Groundwater from the Edwards Aquifer picks up calcium and magnesium as it percolates through limestone, creating water hardness levels well above the 10 grains per gallon threshold. Managing this mineral content is essential for protecting home plumbing and appliance efficiency.
San Antonio tap water contains 15.2 grains per gallon of hardness and 0.7 mg/L of fluoride. Systems like the Elite HE are available in 32,000 to 80,000 grain capacities, backed by a 10-year warranty.
The players
SoftPro Water Systems
A water treatment manufacturer that specializes in residential ion exchange softening technology and high-efficiency filtration hardware.
San Antonio Water System
The local municipal utility responsible for managing water delivery and water quality standards for the San Antonio area.
The details
The Elite HE system uses ion exchange technology to swap calcium and magnesium ions for sodium ions, preventing mineral buildup in pipes and fixtures. Its demand-initiated regeneration microprocessor tracks household usage—based on 75 gallons per person daily—to trigger cleaning only when the resin is depleted. The unit also utilizes NSF/ANSI Standard 44 certified resin to ensure material safety standards.

The Home Front
Residential water treatment has increasingly focused on high-efficiency, demand-initiated systems to reduce salt and water waste. This development follows established NSF/ANSI Standard 44 guidelines for material safety in household ion exchange equipment.
If you are planning an upgrade, calculate your system size by multiplying your household count by 75 gallons per day and the local hardness of 15.2 GPG. Because this process involves plumbing and water line integration, always hire a licensed professional for the installation.
The takeaway
Selecting the correct grain capacity for your water softener is vital to ensuring it cycles correctly and protects your home plumbing from mineral buildup. Consult a licensed professional to assess your home's water pressure and line configuration before finalizing your unit purchase.
