Plumbing in San Antonio: what to know
San Antonio has long, hot summers, mild winters and occasional hailstorms in spring. Slab-on-grade homes over clay soil are common, and the water is hard.
- Heavy rain can overload sewer lines and cause backups; a backwater valve can help.
- Shifting clay soil can crack slab plumbing and sewer lines, so unexplained high water bills deserve a leak check.
- Hard water leaves scale in faucets, shower valves and pipes, which lowers water pressure over time.
How much does plumbing cost?
- Plumber (per hour): $70 – $150
- Burst pipe repair: $190 – $970
- Main sewer line unclog: $340 – $630
