MAP Plumbing and Rooter first confirms whether the symptoms point to a slab-related plumbing leak before recommending a repair path for a Los Angeles property.

From Slab Leak Diagnosis to a Repair Plan
Diagnosis comes before access or repair. We first confirm that water is escaping from plumbing associated with the slab and narrow down the source as closely as site conditions allow. The repair path depends on the pipe route, material, condition, accessibility, and extent of damage.
Possible paths may include accessing the affected area, repairing a confirmed section, or rerouting or replacing a section when direct repair is impractical. We do not assume that every slab leak requires the same amount of concrete or flooring access. For a suspected hidden leak that may be elsewhere, start with general leak detection.
Diagnosis Comes Before Access or Repair
Choosing the Right Slab Leak Repair Path
No repair method or level of disruption can be chosen responsibly until the leak source and pipe route are confirmed. We explain the findings, practical access considerations, and available repair paths before work begins so you can make an informed decision.
