Why slab leaks happen in Brea
Much of Brea's housing from the 1950s through the 1970s was built slab-on-grade, with copper water lines run under or through the concrete. Over decades those lines can wear where they rub against concrete or gravel, where they bend, or where water chemistry slowly thins the pipe wall.
A slab leak is usually not a gushing emergency. It tends to be a quiet, continuous loss that shows up as a higher water bill, a damp patch in carpet or a section of floor that feels warm. If it is on the hot side it can also make the water heater run constantly.
Common signs
- A warm or hot spot on a tile or wood floor.
- The sound of running water when every fixture is off.
- A water bill that jumps without any change in use.
- Damp carpet, swelling baseboards or cracked tile with no obvious source.
- The water heater running more than usual.
- Low water pressure throughout the house.
Test it with your water meter
- Turn everything off.Make sure no faucet, toilet, irrigation, ice maker or appliance is using water.
- Read the meter.Open the meter box at the curb and note the reading, or look at the small leak indicator dial.
- Wait.Leave everything off for 30 minutes to an hour.
- Read it again.If the reading moved or the leak indicator is spinning, water is going somewhere.
- Narrow it down.Close the house main. If the meter stops, the leak is inside the house. If it keeps moving, the leak may be between the meter and the house.
Spot repair or reroute
Once a licensed plumber confirms and locates the leak with leak-detection equipment, these are the two broad paths.
Spot repair through the slab
- Opens the floor and concrete at the leak only.
- Fixes the single failure point.
- Means removing and restoring flooring in that area.
- May be followed by another leak elsewhere on aging pipe.
Reroute above the slab
- Abandons the leaking line and runs a new one through walls or the attic.
- Avoids breaking concrete in most cases.
- Means opening and patching drywall instead.
- Often considered when lines are old or leaks repeat.
What shapes the cost
- How precisely the leak can be located.
- Whether the repair goes through the slab or above it.
- Flooring type over the leak, such as tile, wood or carpet.
- Length of any reroute and the drywall to patch afterward.
- Whether the plumber recommends repiping instead of repeated repairs.
Questions to ask
- How did you locate the leak, and how confident are you of the spot?
- Is it hot or cold side?
- Would you recommend a spot repair or a reroute for this house, and why?
- Does this work need a permit from the City of Brea?
- What is your CSLB license number?
Common questions
- Will my homeowners insurance cover a slab leak?
- Coverage varies by policy, especially for the pipe itself versus the resulting water damage. Ask your insurer.
- Can a slab leak damage the foundation?
- A long-running leak can soak the soil under a slab. That is one reason to act once a leak is confirmed.
- Do I need to stay out of the house?
- Usually not. Close the main when you are not using water and schedule leak detection.
