Completed emergency water line repair for a residential customer in Brentwood today. Located and exposed a 3/4" copper supply line that had developed a pinhole leak approximately 18" below grade. Water was surfacing in the front yard and creating significant saturation. Excavated a 4'x4' area to access the damaged section, installed a 24" copper replacement section using compression couplings to ensure proper connection. Pressure tested the repair to 80 PSI with no signs of leakage. Backfilled the excavation with appropriate bedding material and compacted in 6" lifts to prevent future settling. Restored lawn area with existing sod and applied seed to disturbed areas. Customer's water service was restored after approximately 3 hours of downtime. Recommended full inspection of remaining copper piping as this type of failure often indicates systemic corrosion issues. Left site clean and organized with all debris removed.
