Water Main Repair & Replacement in Long Beach, CA

The water main (also called the water service line) is the supply line running from the city meter at the curb to your house. It's typically 1-inch or 1.25-inch copper or PEX in newer construction, or galvanized steel and (rarely) lead in pre-1970 homes. Failure modes are age-driven: galvanized service lines fail by internal corrosion narrowing the diameter and eventually rusting through; copper fails by pinhole pitting; old lead lines fail by fitting corrosion. Symptoms are persistent low pressure across all fixtures, audible running water at the meter when fixtures are off, a wet patch in the yard between meter and house, or an unexplained jump in the water bill. We trace the leak with electronic equipment, then either spot-repair (single failure on otherwise sound pipe) or trenchlessly replace the whole line (multiple failures, old galvanized, or any lead).

Water main failures in Long Beach concentrate in homes built during the original 1910–1940 and 1940–1965 construction, where 1910s–20s vitrified clay laterals, galvanized supply, and orangeburg laterals (1940s) were standard for service lines. Galvanized service lines from that era are the highest-priority replacement targets — internal rust restricts flow until the entire house has weak pressure, and the line typically fails by rust-through within a 6-12 month window once symptoms start. Copper lines from later eras can pinhole-fail anywhere along the run and usually warrant full trenchless replacement after the second leak. We replace service lines trenchlessly through two small access pits — typically one near the meter and one at the house entry — so the yard, driveway, and any hardscape between them stay completely intact.
