Local context: Montgomery sits atop heavy red clay soils that shift seasonally, stressing sewer lines. Many homes built in the 1960s–1980s still have original cast-iron drains showing advanced corrosion.
A running toilet wastes up to 200 gallons of water per day — meaning a $100 repair can save $30–$60/month on your Montgomery 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.
