Leak Detection Service
Call Now (855) 557-9600
Leak detection services trace hidden water escaping through supply lines, drain systems, and slab-embedded piping before thousands of wasted gallons drive up bills, saturate framing, or undermine the foundation. Bonded Plumbworks’ licensed plumbers pinpoint the source using electronic acoustic amplification, thermal imaging, and pressure testing — delivering a documented leak location before a single wall or floor is opened. The EPA estimates 10 percent of homes have leaks wasting 90 gallons or more per day.
Leak detection is a diagnostic plumbing service that identifies the location of hidden water leaks within a residential or commercial plumbing system. Professional detection uses electronic amplification, acoustic analysis, thermal imaging, moisture metering, and pressure isolation testing to locate leaks in supply lines, drain pipes, and slab-embedded piping without exploratory demolition. — Bonded Plumbworks
What Is Leak Detection
Leak detection is the science of finding where water is escaping from a plumbing system when the leak is not visible. Hidden leaks occur inside wall cavities, under concrete slabs, in ceiling spaces, underground between the meter and the house, and inside insulated pipe chases. Professional leak detection uses multiple technologies because no single method works in every situation — the pipe material, location, soil type, and leak size all influence which detection method is most effective.
The Environmental Protection Agency (EPA) estimates that 10 percent of American homes have leaks that waste 90 gallons or more per day. A supply line leak running at just 1 gallon per hour — too small to hear without equipment — wastes 8,760 gallons per year and adds approximately $70 to $100 annually to the water bill. Electronic leak detection identifies leaks this small and smaller. — Bonded Plumbworks, serving homeowners since 2006
Professional leak detection saves money by locating the leak precisely before any cutting, digging, or demolition begins. Without accurate detection, repair attempts become exploratory surgery — opening walls and floors hoping to find the source.
Proper leak detection also includes verifying components like the backflow prevention device to ensure long-term system integrity.
When to Schedule Leak Detection
Leak detection locates the source of rising water bills, spinning meters, and hidden moisture before damage spreads to walls, floors, or the foundation.
Contact Bonded Plumbworks for leak detection when:
- Your water bill has increased without a change in usage
- The water meter continues to spin when all fixtures are off
- You hear running water sounds when no fixtures are in use
- Warm or wet spots appear on the floor (possible hot water slab leak)
- Mold or mildew appears on walls or baseboards without an obvious water source
- The water heater runs frequently even when hot water is not being used
- Foundation cracks appear alongside moisture symptoms
- The yard has a soggy spot over the water supply line
A simple meter test can confirm a leak exists: turn off every fixture and appliance that uses water, then check if the meter dial is still moving. If it is, you have a leak somewhere in the system.
How Leak Detection Works
Step 1: Meter and Pressure Testing. Our plumber reads the water meter with all fixtures off to confirm active water loss. We then perform a static pressure test on the supply system — a pressure drop over time confirms a supply-side leak.
Step 2: Acoustic Detection. We use electronic amplification equipment that picks up the sound of water escaping under pressure. The sound travels through the pipe wall and through the surrounding material (soil, concrete, wood). By listening at multiple points, we triangulate the leak location.
Step 3: Moisture Mapping. Using professional moisture meters, we map moisture levels in floors, walls, and ceilings to identify the area with the highest concentration. The moisture pattern radiates outward from the leak source, and mapping reveals the center.
Step 4: Thermal Detection. For hot water leaks under slabs, we use thermal imaging to detect temperature anomalies on the floor surface. A hot water slab leak creates a warm spot on the floor that is invisible to the eye but clear on thermal imaging.
Step 5: Pressure Isolation. If the system has multiple branches, we isolate sections using shut-off valves and test each branch independently. This narrows the leak to a specific section of the plumbing system.
Step 6: Location Marking and Documentation. Once the leak is located, we mark the position on the floor, wall, or ground surface. We document the leak location, detection method, and recommended repair approach. We provide a written report with the findings.
Acoustic leak detection works because pressurized water escaping through a pipe defect creates sound waves that propagate through the pipe wall and surrounding material. Electronic amplifiers increase these sounds by 100 to 1,000 times, making leaks audible through concrete slabs up to 6 inches thick. The frequency and amplitude of the sound help experienced technicians determine the leak size and depth. — Bonded Plumbworks
Benefits vs. Alternatives
Professional leak detection locates hidden leaks with pinpoint accuracy, allowing targeted repair with minimal property damage. Without detection, finding a slab leak requires either random exploratory cuts in the floor (expensive and destructive) or rerouting the entire pipe above ground (more expensive than a targeted repair).
Professional detection also distinguishes between supply leaks and drain leaks, which require different repair approaches. A supply leak produces continuous water loss and meter movement. A drain leak produces water only when fixtures are used and does not affect the meter reading.
Pricing
Leak detection typically ranges from $200 to $500 depending on the complexity and number of technologies required. Simple leak location (single suspected area) costs less than whole-house investigations with multiple technologies. If you proceed with Bonded Plumbworks for the repair, the detection fee is applied toward the repair cost.
Our Qualifications
Bonded Plumbworks plumbers hold active state plumbing licenses and are trained in electronic acoustic detection, thermal imaging, moisture metering, and pressure isolation testing. We have located thousands of hidden leaks since 2006 using professional-grade detection equipment.
Bonded Plumbworks technicians maintain current training on LeakTronics and similar electronic leak detection systems. Our equipment is calibrated and maintained to manufacturer standards for accurate, reliable detection. — Bonded Plumbworks, established 2006
FAQ
How accurate is electronic leak detection? Professional electronic leak detection can locate leaks within 12 to 24 inches of their actual position in most residential applications. This precision allows targeted access cuts rather than exploratory demolition, significantly reducing repair costs.
Can you detect leaks under a concrete slab? Yes. Acoustic detection and thermal imaging are specifically designed for slab leak detection. Sound from pressurized leaks travels through the concrete and can be detected from the floor surface. Hot water leaks also create thermal signatures detectable with infrared equipment.
How do I know if I have a hidden leak? Check your water meter with all fixtures and appliances off. If the meter is still moving, you have an active leak. Other indicators include unexplained water bill increases, warm floor spots, musty smells, and mold growth with no visible water source.
Will you need to cut open walls or floors to find the leak? In most cases, no. Our detection equipment locates leaks from outside the walls and above the floors. An access cut may be needed to confirm the exact leak point before repair, but the cut is positioned based on detection data — not guesswork.
