Mainstream repairs a main water line by first locating the leak with non-invasive detection equipment, then either spot-repairing the affected section, trenchless-replacing the full line (when possible), or excavating to replace the line with new copper or PEX-A. Most repairs are completed in 1–2 days including permit, repair, and yard restoration.

Main water line repair process

  • Leak location with thermal/acoustic detection
  • Permit pulled with local jurisdiction
  • Utilities located and marked
  • Spot repair, trenchless pipe replacement, or open trench
  • Pressure test and disinfection
  • Yard restoration
