If your Hawthorne water bill has climbed without a clear reason, a quick meter test is a good first step. Turn off every fixture and water-using appliance, then check the meter near the street. If the dial or small leak indicator keeps turning, water is escaping somewhere. Your bill shows your water provider, which can also help explain your usage.
In older Hawthorne homes, hidden leaks often come from aging supply pipe inside walls, under raised floors or beneath slabs. Clues include a damp or warm spot on the floor, stains on drywall or ceilings, a musty smell, peeling paint near a wall, or the sound of running water when everything is off. In apartments, a stain may come from a unit above, so tell the manager before anyone opens a wall.
Detection methods include acoustic listening, pressure testing and thermal imaging, all aimed at finding the source before opening walls or floors. Ask the contractor which methods they will use, what the detection fee covers and whether repair is quoted separately. See our California leak detection page for more.

- 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

- 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.
