Water and Sewer Line Slab Leaks in San Ramon, CA
Slab leaks can affect both freshwater supply lines and sewer drain pipes. Our detection services are equipped 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 appear as wet spots or high water bills in your San Ramon, CA home. We have specific methods for each.

Hot Water Slab Leak Detection in San Ramon
Hot water lines leak under slabs more often than cold lines because heat speeds up corrosion and causes expansion and contraction. Signs include warm spots on the floor, a water heater that runs nonstop and higher gas or electric bills. Thermal imaging shows the heat pattern spreading through tile or concrete. We confirm with a pressure test and acoustic listening before flagging the spot.
Slab Leak Reroutes in San Ramon
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 popular when the slab is covered in tile or hardwood.
Emergency Slab Leak Detection in San Ramon
A sudden drop in water pressure, visible dampness or the sound of running water can indicate an emergency slab leak. FBL Plumbing offers emergency detection services in San Ramon to address urgent situations quickly. We focus on rapid response to limit water damage and prevent further structural compromise to your property.

Our goal is to promptly find the leak, provide a clear explanation and offer effective repair solutions to protect your home and peace of mind.
Slab Leak Repair Through Direct Access in San Ramon, CA
When a single leak is found on otherwise healthy pipe, direct access can be the most economical repair. We cut a small opening in the floor at the marked spot, repair the pipe and pressure test it. Then we patch the concrete and leave the area ready for flooring. Accurate detection keeps that opening as small as possible.
Cold Water Slab Leak Detection in San Ramon, 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.

Many older homes in San Ramon, CA have copper or galvanized steel pipes that are more susceptible to corrosion and leaks over time.

Common signs of a slab leak include surprisingly 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.
