Local context: San Antonio's Edwards Aquifer water is exceptionally hard — 300–400 ppm, among the hardest municipal water in the US. Water softeners are nearly universal. The limestone bedrock beneath the city can be encountered as little as 12 inches below the surface, making trench work very expensive.
Pipe repair in San Antonio ranges from a simple $150 pinhole leak fix to a full-home repipe costing $3,000–$15,000+. The right solution depends on pipe material, age, and how widespread the problem is.

Repair vs. Repipe: Which Do You Need?
- • Single, isolated leak in a newer pipe system
- • Damage from impact or accident (not corrosion)
- • Repair cost is under $600–$800
- • Rest of the system is in good condition
- • Multiple leaks in different areas
- • Galvanized pipes 40+ years old
- • Chronic low water pressure
- • Discolored or metallic-tasting water
San Antonio's very hard water accelerates scale buildup and corrosion inside pipes, shortening the effective service life. If you're doing a repipe, consider adding a whole-home water softener to protect the new pipes.
