How Detection Really Works
Professionals don’t guess—they detect. Some of the tools and processes include:
- Initial visual inspection
Checking for stains, cracks, moisture, foundation issues. Premier Plumber Pasadena - Acoustic listening devices
Sensitive tools that detect water escaping under pressure through concrete. Premier Plumber Pasadena - Thermal imaging cameras
Detect hot water lines leaking by heat signature differences in floors/walls. Premier Plumber Pasadena - Pressure testing
Isolate sections of plumbing and monitor pressure drop; detects exactly which line is compromised. Premier Plumber Pasadena - Video inspection (for sewer lines)
Small flexible cameras inserted into drains to identify cracks or damage inside pipes. Premier Plumber Pasadena - Tracer gas detection
For leaks that are hard to locate—gas escapes through tiny holes, detected above the surface. Premier Plumber Pasadena
Repair Options Once Leak Is Found
Depending on what detection reveals, here are common repair approaches:
- Spot repair
If the leak is localized, break through slab just where needed to fix the pipe. Premier Plumber Pasadena - Pipe rerouting (bypass)
Avoid the damaged section by installing new lines outside the slab. Useful when access under slab is too destructive. Premier Plumber Pasadena - Pipe relining / Epoxy coating
For drain lines or small leaks, trenchless methods like relining or coating can seal things up. Premier Plumber Pasadena - Tunneling
For complex leaks or multiple problem areas—dig from outside beneath foundation to reach pipes without opening interior slabs. Premier Plumber Pasadena
Preventing Slab Leaks: What You Can Do Now
While detection and repair are key, prevention helps reduce risk:
- Monitor water pressure
Keep water pressure below damaging levels. If consistently high (> ~80 psi), install a pressure regulator. Premier Plumber Pasadena - Ensure proper drainage around the foundation
Gutters, proper grading, directing runoff away from home. Soil saturation and shifting is a big culprit. Premier Plumber Pasadena - Mind landscaping
Large trees or shrubs with deep roots can interfere with pipes. Plant them a safe distance from slab. Premier Plumber Pasadena - Regular plumbing inspections
Even if everything seems fine—scheduled checks can catch corrosion, wear, early leaks. Premier Plumber Pasadena
