Where Pittsburg homes leak

Slab homes. Many Pittsburg neighborhoods built from the 1960s through the 1980s sit on concrete slabs with copper lines underneath. After decades, pinhole leaks can appear, often in hot lines first. Warm floors, cracked tile and a meter that never stops moving are common clues.

Expansive clay soil. Much of Pittsburg sits on clay that shrinks in summer and swells in the rainy season. That movement stresses under-slab pipes, yard service lines and connections where pipes enter the house. Leaks sometimes appear after the first big rains of the season or after a long dry spell.

Yard and irrigation lines. Large lots and landscaped yards in neighborhoods like San Marco, Vista del Mar and Oak Hills mean long irrigation runs and service lines. A soggy area in a dry summer lawn, or a sunken patch of soil, can point to a buried leak. Irrigation leaks are among the most common causes of a sudden bill spike.

Old Town. Older homes may have galvanized pipe in a crawl space, leaking at threaded joints out of sight.

A quick check

Turn off all water use, including irrigation controllers. Watch the meter's low-flow indicator. If it moves, close the main at the house. If it still moves, the leak is between the meter and the house, or on an irrigation line fed before the house valve.

How leaks are located

Contractors isolate and pressure test sections, then use acoustic listening, thermal imaging and line tracing to pinpoint leaks before opening anything. For leaks at the meter or in the street, contact the City of Pittsburg's water team. Related: Pittsburg plumbing guide, water heater repair in Pittsburg and the statewide leak detection guide.

Signs of a hidden leak

• A water bill that rises without a change in use
• The water meter's low-flow indicator moving while every fixture is off
• A warm or damp spot on a slab floor, or cracked and lifting tile
• The sound of running water inside a wall or under the floor
• Mold, musty odors, or stains on drywall and baseboards
• Low water pressure on one line
• A soggy patch in the yard between the meter and the house

Why California homes leak where they do

California's housing boom after World War II produced hundreds of thousands of slab-on-grade tract homes across Los Angeles County, Orange County, the Inland Empire and the Bay Area. In many of them, copper water lines run beneath the concrete. After decades of service, copper can develop pinhole leaks from internal wear, water chemistry or abrasion against the slab. Hot water lines often fail first, which is why a warm patch on the floor is a classic clue.
