A slab leak in Imperial Beach is a pressurized water line leaking beneath or inside a home's concrete floor. California American Water delivers the water, while the customer-side plumbing, including pipes under the slab, is the owner's responsibility.

Imperial Beach homes and water
Imperial Beach is a highly residential beach city. In its slab-built houses and small multi-family buildings, supply lines run through or under the concrete floor. Salt air near the ocean is hard on exterior fixtures and exposed pipe, but a slab leak starts underneath, usually where copper rubs on gravel or a fitting gives way.
California American Water serves Imperial Beach through its Coronado system, which buys treated water from the City of San Diego and chloraminates it. Hardness at the source plants runs about 8.5 to 16.4 grains per gallon. That causes scale in heaters and fixtures, but Cal Am's report doesn't connect it to slab leaks. Cal Am distinguishes its distribution system from the customer-owned service line and reports no lead service lines in any of its systems, including customer-owned lines. If water is coming up on the public side, Cal Am lists 1-888-237-1333 for emergencies.
Choosing a repair
| Option | Best for | Consider |
|---|---|---|
| Open the slab and splice | One leak, accurately located, in otherwise sound pipe | Flooring and concrete are cut and restored; matching tile can be tricky |
| Reroute through walls or attic | Leaks under cabinets or hard flooring, or a line that has leaked before | Drywall openings to patch; old pipe stays buried but unused |
| Repipe | Multiple leaks or a system near the end of its life | Bigger job, but no buried supply lines remain |
What to watch for
- A meter that keeps moving with nothing running
- Warmth in one area of the floor
- Damp carpet or a musty odor along an interior wall
- The water heater running more than it should
- A bill that jumps with no change in use
Timing
Water under a slab keeps spreading, softening the soil and working into flooring, so a confirmed leak should be fixed within days. In a duplex or small apartment building, one leak can affect more than one unit, so tell the owner or manager right away. On permits, Imperial Beach requires them to install or alter plumbing systems; applications go through the city's Citizen Self-Service portal, and the plumber can confirm what your repair needs.
