Local context: Austin is built on limestone (the Edwards Plateau). Trenchless sewer methods are nearly always required because excavation hits rock within 12–18 inches. Austin Water's Lake Travis source runs moderately hard (150–200 ppm), and the exploding population has stretched sewer capacity.
A running toilet wastes up to 200 gallons of water per day — meaning a $125 repair can save $30–$60/month on your Austin water bill. Most toilet problems are inexpensive to fix. The key is catching them early and not ignoring the sound of a constantly running tank.

Repair vs Replace: Decision Guide
- • Toilet is less than 15–20 years old
- • Repair cost is under $300–$400
- • No cracks in the porcelain bowl or tank
- • Only one or two components need replacing
- • Toilet is 20+ years old (pre-1994 uses 3.5–7 gpf)
- • Cracks in bowl or tank (irreparable)
- • Needs 3+ simultaneous repairs
- • Frequent clogs from design issues
Austin's hard water accelerates mineral buildup inside fill valves and flush valves, causing them to fail faster than the national average. If components fail every 2–3 years, a whole-home water softener can extend the life of all plumbing fixtures and appliances.
