Local context: Anchorage gets ultra-soft glacier-fed water from Eklutna Lake (15-25 ppm) so soft it is mildly corrosive to copper. Extreme cold (-30F possible) requires pipe burial 6-8 ft below frost line and heat tape on all exposed runs. Labor costs run 55 percent above national average.
A running toilet wastes up to 200 gallons of water per day — meaning a $150 repair can save $30–$60/month on your Anchorage 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.
