Pool and Spa Leak Detection in Sunnyvale
Summer heat and wind can evaporate a lot of pool water, so it can be hard to tell normal loss from a leak. A bucket test compares evaporation to actual water loss. We then pressure test plumbing lines and use dye testing around lights, skimmers and fittings. Finding the leak protects the pool shell and the soil around it.

Slab Leak Detection in Sunnyvale
Slab leaks are a common concern for homes with concrete foundations, especially where soils shift. Our technicians use dedicated acoustic equipment and thermal cameras to pinpoint leaks under your home's foundation without destructive digging. Early detection of a slab leak prevents serious structural damage and mold issues, saving you real repair costs down the line. We can locate leaks in both hot and cold water lines under the slab.
Sewer Line Leak Detection in Sunnyvale, CA
Sewer line leaks can cause foul odors, slow drains and potential health hazards. Our team uses camera inspections to visually identify breaks, cracks or blockages within your sewer lines. This method allows for precise location of the leak without guesswork, leading to more efficient and targeted repairs. We address sewer leaks in all types of piping materials common in Sunnyvale homes, from PVC to cast iron.
Preventative Leak Detection Inspections in Sunnyvale, CA
Beyond emergency services, FBL Plumbing also offers preventative leak detection inspections. Regular inspections can identify small leaks before they become major problems, especially in older homes or properties with known plumbing issues. This proactive approach helps extend the life of your plumbing system and can save thousands in potential repair costs, especially for homes with aging infrastructure.
Irrigation and Yard Leak Detection in Sunnyvale, CA
Drip and sprinkler systems are a common source of hidden water loss in many yards. A cracked lateral or a stuck valve can waste thousands of gallons before anyone notices. We test the irrigation system separately from the house and trace leaks along buried lines. Many water providers recommend checking irrigation first when bills spike in summer.
Leak Detection Cost Comparison in Sunnyvale, CA
Professional leak detection usually costs $150 to $450 for a standard home, depending on the system size and how many areas need testing. Pool leak detection usually runs $250 to $500. Repair costs vary a lot, from $150 for a fixture fix to several thousand dollars for a slab reroute. Accurate detection keeps the repair cost as low as it can be.
Main Water Line Leak Detection in Sunnyvale
The service line between your meter and house can leak underground for months, especially in older galvanized or copper lines. Wet spots in the yard, unusually green grass or a sinking area near the front of the house are clues. We use line tracers to map the pipe and ground microphones to hear the leak. That keeps excavation to a small, focused hole.

PEX and Copper Pipe Leak Detection in Sunnyvale, CA

We are experienced in detecting leaks in all common piping materials found in Northern California homes. Our tools are designed to work effectively with both metallic and non-metallic pipes, so no matter your plumbing system, we can accurately locate any leak. We handle everything from pinhole leaks to joint failures.
