Local context: Portland uses Portland Water District from Sebago Lake -- very soft at 20-40 ppm, among the purest public water supplies in the US. Dense 1850s-1900s Victorian and Federal-style housing with cast-iron and lead pipe systems in various stages of deterioration. Rocky Maine terrain makes underground work expensive. Winters reach -20F.
Pipe repair in Portland ranges from a simple $175 pinhole leak fix to a full-home repipe costing $3,300–$16,500+. The right solution depends on pipe material, age, and how widespread the problem is. Many older Portland homes still have original galvanized or cast-iron pipes that are well past their design lifespan.
