Leak Detection for PEX and Copper Pipes in Fresno
Whether your plumbing system uses modern PEX tubing or traditional copper pipes, FBL Plumbing has the expertise to detect leaks in both materials. PEX, while flexible, can be vulnerable to damage from rodents or improper installation, while copper can corrode over time, especially with hard water. Our tools are effective across various pipe materials, ensuring accurate detection regardless of your home's plumbing type.

Pool Water Leak Detection in Fresno, CA
Pools lose a lot of water to evaporation in summer heat, so a leak can hide behind normal loss. We use a bucket test to compare evaporation with actual water loss. Then we pressure test pool plumbing and dye test fittings, lights and skimmers. Finding the leak protects the pool and the soil around it.
Smart Leak Detection Device Installation in Fresno
Smart shutoff valves like Moen Flo and Phyn monitor water flow and can shut off water automatically when they detect a leak. Small sensors placed near water heaters, sinks and washers send alerts to your phone. We install and set up these systems so you get warnings before small leaks become big ones. Some insurers offer discounts for these devices.
Pinhole Leak Detection in Fresno, CA
Pinhole leaks, often found in copper or PEX piping, are small but can cause serious damage over time, especially behind walls or under floors. We use non-invasive moisture meters to detect elevated humidity levels and thermal cameras to identify cold spots that indicate water. Our plumbers are adept at tracing these elusive leaks without tearing apart your entire home. Swift action on pinhole leaks prevents extensive drywall damage, mold growth and compromised structural integrity. Wet winters and long dry summers define the plumbing calendar in Northern California, with drainage problems in the rainy season and irrigation leaks in summer.
Irrigation Leak Detection in Fresno
Drip and sprinkler systems run underground across yards and often account for hidden water loss. Cracked tubing, broken emitters and stuck valves can waste huge amounts of water. We isolate the irrigation system, test each zone and trace leaking lines. Repairs restore proper watering for your landscape.
Emergency Water Leak Detection in Fresno, CA
Some leaks require urgent attention, particularly those causing significant water damage or posing a threat to your property's stability. FBL Plumbing provides emergency water leak detection services throughout Fresno, CA, offering fast response to urgent situations. Our goal is to quickly find and contain the leak to prevent further damage and begin the necessary repairs as soon as possible, day or night.
Main Service Line Leak Detection in Fresno, CA
The line from the meter to your house carries full pressure and can leak underground for a long time. Wet soil, soft spots or oddly green patches of yard may be the only clues. We trace the line, listen for the leak and mark it for a targeted repair. Replacing old galvanized or polybutylene service lines is often recommended.

Underground Water Line Leak Detection in Fresno
Leaks in underground water lines, from your meter to your home, can go unnoticed for long periods, wasting water and causing yard erosion. Signs include oddly green patches in your lawn, persistent wet spots or a constantly running water meter. FBL Plumbing employs ground-penetrating radar and tracer gas detection methods to accurately map out and pinpoint leaks in buried pipes, allowing for targeted excavation and repair rather than digging up your entire yard.

Frequently Asked Questions About Water Leak Detection in Fresno
The cost of water leak detection in Fresno, CA typically ranges from $250 to $750, depending on the complexity and location of the leak. Factors like whether it's a slab leak, a wall leak or an outdoor pipe leak can affect the final price. This initial cost covers the specialized equipment and expertise needed to accurately pinpoint the problem before any repairs begin.
We use professional equipment including acoustic listening devices, thermal imaging cameras, moisture meters, video pipe inspection cameras and sometimes tracer gas detection. These tools allow us to locate leaks non-invasively and with high precision.
Yes, a persistent water leak under your home can cause significant foundation damage. Expansive clay soils are common across Northern California, and seasonal swelling and shrinking can crack slabs and buried sewer laterals. Water saturates the soil, leading to expansion and contraction that can shift or crack your foundation, so slab leaks make prompt detection crucial.
Common signs of a hidden water leak include unexplained high water bills, damp spots on walls or floors, the sound of running water when no fixtures are in use, a musty odor or visible mold growth. Also, a sudden drop in water pressure or changes in your water meter reading when no water is being used can indicate a problem.
Yes, hard water can contribute to plumbing issues over time. Mineral buildup can speed up corrosion in pipes, especially older copper or galvanized lines, increasing the likelihood of leaks. Regular maintenance can help limit this.
If you suspect a slab leak, the first step is to call a professional like FBL Plumbing right away. Avoid trying to dig or open up the slab yourself, as this can cause more damage. Turn off your main water supply if the leak is severe, and clear the area for our technicians.
Irrigation and pool top-offs naturally increase summer use. But a big jump compared to last summer often points to a leak, especially in irrigation. We can test to find out.
While leak detection itself usually doesn't require a permit, extensive repairs involving opening walls, altering structural elements or replacing major sections of plumbing often do. FBL Plumbing will handle all necessary permit applications for any repair work we perform in Fresno.
