A San Clemente slab leak is fixed either by opening the floor at the leak or by running a new line around the concrete, and a plumber locates the leak first so the choice is informed. Pipe replacement may need a permit from the City's Community Development Building Division. Call the number on this page to be connected with a local plumber in San Clemente.
Why are slab leaks turning up in San Clemente homes?
Age and construction. The median San Clemente home was built in 1982, and about 69% of housing units are single-family houses, many of them slab-on-grade. Original copper lines in or under that concrete have now been through four decades of hot and cold cycles, settling and friction against the slab. Leaks tend to start at bends, at joints and where pipe touches concrete or gravel.
City water is hard, with the City's report listing 293 mg/L (17 grains per gallon) for water from the Baker plant and 236 mg/L (14 grains per gallon) for Metropolitan treated water. That scale is mostly a problem for water heaters and fixtures, but it's one more reason to have a plumber look at the whole system when a slab line fails.
Should I fix the spot or reroute the line?
It depends on the pipe and the floor. If the leak is a single failure and the rest of the line tests sound, a direct repair through the slab can be the most contained job. If the line has leaked before, runs a long distance under the house or sits beneath tile or hardwood you want to keep, rerouting through walls or the attic often makes more sense. When several lines are failing, a repipe ends the cycle. Replacing or adding pipe may require a permit from the City of San Clemente Community Development Building Division.
Who do I call if the leak is near the street?
That depends on your water provider. The City Water Utility serves most of San Clemente, Santa Margarita Water District serves Talega, and South Coast Water District serves a small portion of north San Clemente. Check your bill. City customers can report water leaks on the City utilities hotline at 949-366-1553. A leak beneath the house itself is a private repair, so that's a call for a plumber.
Local note
In coastal neighborhoods, salt air and the marine layer corrode exterior piping and hose bibs, so a plumber working on a slab leak may also flag outside valves near the end of their life. Fixing them during the same visit can save a second trip.
