Video Pipe Inspection for Sewer Leaks in San Clemente, CA
Sewer line issues under a slab can also look like slab leak symptoms. We use high-resolution video cameras to inspect the interior of your drain lines, identifying cracks, blockages or separations. This is vital if the issue isn't a pressurized water line, helping us determine if a sewer line repair is needed instead for your San Clemente home.

Water and Sewer Line Slab Leaks in San Clemente, CA
Slab leaks can affect both freshwater supply lines and sewer drain pipes. Our detection services are set up to identify both types of leaks, which present different challenges. Sewer line leaks often involve foul odors and slow drainage, while water line leaks can show up as wet spots or high water bills in your San Clemente, CA home. We have specific methods for each.
Post-Tension Slab Leak Detection in San Clemente
Many newer homes are built on post-tension slabs that use steel cables under high tension. Cutting into one without care is dangerous and can damage the foundation. We locate the cables with scanning equipment before any repair access is opened. This lets us repair the leak safely or recommend a reroute that avoids the slab entirely.
Slab Leak Reroutes in San Clemente
Rerouting abandons the leaking line under the slab and runs new pipe through the walls or attic. It avoids breaking concrete and often costs less than direct access under finished floors. We typically use PEX for reroutes because it handles heat and resists hard-water corrosion. This option is a good fit when the slab is covered in tile or hardwood.
Cold Water Slab Leak Detection in San Clemente, CA
Cold water slab leaks do not create warm spots, so they are more difficult to see. They often show up as a running water meter, damp carpet, a musty smell or water seeping at baseboards. We isolate the cold side and use acoustic equipment to listen for the leak through the slab. Line tracers map the pipe route so we know where to listen.
Leak Detection for Older Southern California Homes in San Clemente, CA
Many older homes in San Clemente, CA have copper or galvanized steel pipes that are more susceptible to corrosion and leaks over time. Our technicians are highly experienced in detecting leaks in these older systems, understanding their common failure points. We provide careful analysis for the challenges presented by vintage plumbing under concrete slabs.
Electronic Acoustic Leak Detection in San Clemente
Our team uses electronic listening devices to pinpoint the exact location of a slab leak. These highly sensitive microphones can detect the faint sound of water escaping from a pressurized pipe under your foundation. This non-invasive method helps us avoid unnecessary concrete breaking, saving you time and money on repairs. It's especially effective for copper and PEX lines commonly found in San Clemente homes.

Common signs of a slab leak include unusually high water bills, warm spots on your floor, the sound of running water when no fixtures are in use, visible cracks in the foundation, damp or wet spots on carpets or flooring and a sudden drop in water pressure. Musty odors can also point to moisture buildup.
We stand by the accuracy of our slab leak detection services. While detection itself is a diagnostic service, we make sure our findings are precise. Any subsequent repairs performed by FKM Plumbing come with our standard labor and parts warranties, which will be clearly outlined for you.
Common pipe materials prone to slab leaks include older copper pipes susceptible to corrosion from hard water or soil acidity, and sometimes PEX or CPVC if they were improperly installed or exposed to extreme temperatures. Galvanized steel pipes, though less common under slabs today, can also corrode and leak.
Reroutes and repipes often require a plumbing permit, while small direct repairs may not. Requirements vary by city and county. We take care of permits and inspections when needed.
