Hidden plumbing leaks can be difficult to pinpoint, even when the warning signs are clear. At PureFlo, we use a systematic leak detection process throughout Jacksonville and Northeast Florida to identify the source before recommending the right repair.
Before we start testing, we want to hear about signs you have been noticing. The details you provide can help us determine where to start and which parts of the plumbing system deserve closer attention.
We may ask:
A homeowner’s observations can be just as useful as the first test we perform. If you tell us that the floor became warm before your water bill increased, for example, that gives us a different starting point than a leak that appeared after an irrigation repair.
Before reaching for specialized equipment, we walk through the property and look at what we can see. This gives us an opportunity to identify obvious sources of water loss and understand how the plumbing system is laid out.
Our inspection may include accessible fixtures, toilets, the water heater, hose bibbs, shutoff valves, cabinets, ceilings, and other areas where leaks commonly develop. Depending on the home, we may also inspect accessible crawlspaces or attic areas and look at exterior conditions such as grading and wet areas in the yard.
We are looking for evidence that can help connect the symptoms to a potential source:
Water stains. Damp materials. Corrosion. Active dripping. Unusual moisture. Changes around fixtures. Wet areas outside.
Sometimes the visual inspection identifies the problem immediately. Other times, everything visible looks normal. That does not rule out a hidden leak. It simply tells us that we need to look beyond what we can see.
If there is no obvious source of water use, the next question is whether water is moving through the system when it should not be.
We make sure intended water use is stopped, then observe the home’s JEA water meter and leak indicator. We document whether the meter continues to register movement and determine whether there is continuous flow.
A moving meter can confirm that water is being used somewhere on the property. It does not tell us where the water is going.
That distinction is important. The water could be moving through a concealed pipe, an underground water line, a fixture that is leaking silently, or another part of the system.
The meter helps us confirm that there is a problem to investigate before we move into more targeted testing.
Once continuous water loss has been established, pressure testing can tell us more about how the plumbing system is behaving.
We isolate portions of the system and monitor whether pressure holds or begins to drop. Depending on the situation, testing may involve the domestic water system, individual sections of plumbing, the slab plumbing, or the irrigation system.
Pressure decay can help us determine whether a particular section of plumbing is losing water. It can also help separate one part of the system from another.
Pressure testing narrows the search. It does not pinpoint the exact leak location by itself.
If a specific section shows pressure loss, we have a smaller area to investigate. That information can then guide the use of acoustic equipment, thermal imaging, pipe tracing, or another diagnostic method.
Pressurized water escaping from a damaged pipe can create a sound that travels through surrounding materials. When that pipe is beneath a slab or underground, that sound can provide an important clue.
PureFlo uses electronic acoustic listening equipment and ground microphones to detect sounds associated with pressurized leaks.
The technician does not simply listen in one spot and assume the answer is there. We check multiple points around the suspected area and compare the sounds and signal characteristics.
As we move across the suspected area, we compare the sound signatures being detected. Stronger or more consistent signals can help us progressively narrow where the leak is most likely located.
Other environmental sounds can also affect what the equipment picks up, so interpretation matters.
The goal is to distinguish the sound of escaping water from everything else happening around the property.
Thermal imaging can be especially useful when there is a temperature difference associated with a leak. This can include hot-water leaks beneath slabs, areas where moisture is affecting building materials, or other temperature anomalies that may provide another clue.
An infrared camera allows us to see temperature patterns that are not always visible to the naked eye.
But thermal imaging is not a magic leak detector.
Not every plumbing leak creates a temperature difference that an infrared camera can detect. That is why PureFlo uses thermal imaging when the conditions make it useful, rather than relying on it as the only diagnostic method.
Water does not always stay directly around the point where it enters a building material. It can travel through drywall, flooring, cabinets, insulation, and other materials before becoming visible.
That is why PureFlo looks at more than just the wet spot.
Moisture meters help us measure moisture levels in affected materials.
Wall scanning can help identify areas that may contain elevated moisture behind or within finished surfaces.
Flooring checks can help determine whether moisture has affected surrounding flooring materials.
Drywall comparisons allow us to compare readings from an affected area with nearby areas that appear normal.
We document these findings so there is a clearer picture of where moisture is present before repairs begin.
The wettest area is not always the source of the leak. It may simply be where the water ended up.
Moisture mapping becomes much more useful when those findings are compared with pressure testing, meter testing, acoustic results, thermal images, and the known plumbing layout.
Before opening a wall or breaking into concrete, it helps to know what is actually underneath or behind the surface.
Concealed water lines can take unexpected routes through a home. Pipe tracing and utility location equipment can help PureFlo understand where those lines run and verify the path of the plumbing.
This can be especially important when investigating underground service lines or suspected leaks beneath slabs.
Understand the plumbing route
Identify where a concealed water line travels.
Verify pipe paths
Confirm whether the suspected leak area corresponds with the actual plumbing layout.
Locate service lines
Help identify underground water-line routes across the property.
Plan access more carefully
Provide additional information before a repair requires opening a wall, floor, or concrete.
The better we understand the plumbing layout, the less we have to rely on assumptions.
By this point, we are no longer looking at each symptom or test result on its own. We are comparing everything we have learned throughout the investigation.
When We Put Everything Together, That’s When the Picture Becomes Clearer.
Once PureFlo has confirmed the likely source, we explain what we found and what it means for your plumbing system.
Depending on the condition of the plumbing and the location of the leak, repair options could include:
We explain the available options along with the advantages, limitations, and considerations of each.
The goal is education, not pressure.
You should understand what failed, why it failed, and why a particular repair is being recommended before deciding how you want to move forward.
Jacksonville homes vary considerably in age, construction, plumbing materials, and foundation type. A home in Mandarin or Southside may have concealed slab plumbing that requires a different diagnostic approach than a home in Riverside, Avondale, or San Marco, where plumbing may run through walls, ceilings, crawlspaces, or other areas of an established home.
Properties in Arlington, Ortega, Springfield, and Murray Hill can also have decades-old plumbing materials that require a closer look when leaks begin recurring. The material itself does not determine whether replacement is necessary, but it can provide important context when combined with the home’s repair history and current symptoms.
That is why PureFlo does not use a one-size-fits-all approach to leak detection. We look at the home, the plumbing, the symptoms, and the evidence together.
There is no single timeframe that applies to every leak. The process depends on the symptoms, the plumbing layout, and what the initial tests reveal. PureFlo begins with the homeowner interview and visual inspection, then uses meter testing, pressure testing, and more targeted diagnostic methods as needed to progressively narrow down the source.
No. Finding a suspected slab leak does not mean concrete should immediately be opened. PureFlo first uses diagnostic methods such as pressure testing, acoustic leak detection, thermal imaging, and pipe tracing to narrow down the affected area. The goal is to gather enough evidence before recommending invasive access or repair.
No. Thermal imaging is especially useful for identifying temperature anomalies associated with hot-water slab leaks and certain moisture patterns, but it cannot detect every plumbing leak. Cold-water leaks may produce little or no useful temperature difference, which is why infrared imaging is used alongside other diagnostic methods.
Insurance coverage varies by policy and by the circumstances surrounding the leak. PureFlo’s role is to identify the source, document the findings, and explain the plumbing issue. For questions about whether leak detection, plumbing repairs, or resulting water damage are covered, homeowners should confirm the details directly with their insurance provider.
Yes. Underground water-line investigations can involve meter testing, pressure testing, acoustic listening equipment, and pipe-tracing or location equipment. These methods help confirm water loss, understand where the service line runs, and progressively narrow down the area where the leak may be located before repair work begins.
Once PureFlo identifies the leak, we explain where it is, what caused it, and what the findings mean for your plumbing system. We then recommend the most appropriate repair, whether that means a localized pipe repair, reroute, water line replacement, slab repair, or repipe. You’ll understand your options before any repair is recommended, so you can make an informed decision without the guesswork.
PureFlo uses professional testing and specialized equipment to diagnose hidden plumbing leaks throughout Jacksonville and Northeast Florida, helping identify the source before recommending the right repair.
