Local context: Charleston uses West Virginia American Water from Elk River -- moderate hardness at 80-150 ppm. State capital and 2014 Freedom Industries chemical spill site (MCHM contamination). Kanawha River flood risk creates recurring basement water damage. Many 1930s-1960s government-era buildings with aging galvanized and cast-iron systems.
A running toilet wastes up to 200 gallons of water per day — meaning a $75 repair can save $30–$60/month on your Charleston 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.
