A water leak can show up in a lot of ways — a spike in your water bill, a damp spot on the floor, the sound of running water when everything is turned off. Whatever sent you searching for help, calling a plumber for a leak detection service call is the right move. Still, a lot of people aren’t sure what to expect once they pick up the phone. This walkthrough covers the process from start to finish, so there are no surprises.
How the Service Call Starts
When you call to schedule, a good plumber will ask you a few questions upfront. They want to understand what you’re experiencing before anyone drives out. Is there visible water? Where in the house did you notice it? Has anything changed recently — a new appliance, higher water bill, recent storm? These questions help the plumber arrive prepared with the right tools and a general sense of where to start looking.
For homeowners in the Tampa Bay area, slab foundations are extremely common, and that changes how leak detection is approached compared to homes with crawl spaces or basements. Knowing what type of foundation your home sits on matters from the first phone call.
The Initial Walk-Through and Assessment
Once the plumber arrives, the first thing they’ll do is walk the property with you. This isn’t just small talk — it’s part of the plumber inspection process. They’re looking at your water meter, checking visible pipes, inspecting under sinks, and listening for anything unusual. If you’ve noticed specific symptoms, point them out. The more context you can offer, the more efficient the diagnosis will be.
The plumber will also want to know your water source. In parts of Hillsborough County and the surrounding Tampa Bay area, properties run on well systems rather than municipal water. That affects both the diagnostic approach and what kinds of leaks are most common. Hard water and mineral buildup — very familiar issues in Central Florida — can also factor into what the plumber is looking for.
Checking the Water Meter First
Before using any special equipment, most plumbers start with a simple meter check. You turn off all water in the home, then watch the meter. If the dial or digital display is still moving, water is leaving the system somewhere it shouldn’t be. This basic test confirms whether there’s an active leak before the deeper work begins.
Leak Detection Tools and Methods
Modern professional leak detection doesn’t always mean tearing up floors or cutting into walls. Licensed plumbers use a range of non-invasive tools to locate leaks with accuracy before any repair work starts.
Electronic Listening Equipment
Ground microphones and acoustic listening devices can pick up the sound of water moving through pressurized pipes underground or behind walls. This is especially useful for suspected slab leak detection, where the leak is beneath a concrete foundation. The plumber places the sensor at various points and listens for the frequency that running water produces. It takes experience to read correctly, but it narrows down the location significantly.
Drain Camera Inspection
For leaks that may be coming from inside a drain line or sewer lateral, a camera can be inserted directly into the pipe. Drain camera inspection lets the plumber see the interior of the pipe in real time — cracks, root intrusion, separations, and corrosion all show up clearly on screen. It removes the guesswork from drain-related water leak diagnosis.
Pressure Testing
If the leak is suspected in the supply lines, a plumber may isolate sections of the pipe and test them under pressure. A drop in pressure indicates a breach somewhere in that section. This method helps narrow a large system down to a manageable area for further investigation.
Thermal Imaging
Some plumbers use infrared cameras to detect temperature differences behind walls or under floors. Moisture changes the thermal signature of a surface, and a trained plumber can use that data to identify where water may be collecting. It’s a useful tool when other methods haven’t pinpointed the exact location.
What Happens After the Leak Is Located
Once the source is identified, a professional will walk you through what they found before recommending any next steps. This is where the communication matters just as much as the diagnosis. A trustworthy plumber explains the issue clearly — what type of leak it is, where it is, and what the repair involves. They present options and let you make the decision. There’s no pressure, no manufactured urgency.
At Conyers Plumbing, this is a core value: upfront pricing and no soliciting work that wasn’t asked for. That’s been the standard for over 30 years, and it’s how a family-owned plumbing company earns long-term trust in the communities it serves.
Depending on what’s found, the plumber may recommend a targeted pipe repair, whole-home repiping if the system shows widespread deterioration, or additional investigation if the leak has affected other parts of the system. In some cases, what looks like a single leak turns out to be a symptom of a larger issue — aging galvanized pipes, corrosion from hard water, or root intrusion in older drain lines. You deserve to know the full picture.
What You Can Do Before the Plumber Arrives
You don’t need to diagnose the leak yourself, but a few things can help the process move faster. Know where your main water shut-off valve is. Take note of any unusual smells, stains, sounds, or soft spots in flooring. If your water bill jumped recently, have that information handy. And if you have any records from previous plumbing work, those can be helpful too.
If you’re dealing with visible water damage or water actively spreading, shut off the main valve first and then call. That one step can limit the damage while you wait for a plumber to arrive.
After the Service Call
A good leak detection service call ends with clarity. You should walk away knowing what was found, what caused it, and what your repair options look like. A written summary or work order helps document the findings — especially useful for insurance claims or future reference if the issue recurs.
For commercial property owners in the Tampa Bay area, thorough documentation also matters for code compliance and maintenance records. Whether it’s a multi-unit building, a small retail space, or a restaurant, the same principle applies: a plumber should leave you better informed than when they arrived.

Frequently Asked Questions
How long does a leak detection service call typically take?
Most residential leak detection visits take one to three hours, depending on the size of the property and how accessible the suspected area is. Slab leak investigations or larger commercial properties may take longer. The plumber will give you a clearer time estimate once they’ve done an initial walk-through and understand the scope of the job.
Do I need to do anything to prepare before the plumber arrives?
It helps to clear access to areas like under-sink cabinets, utility closets, and your water heater. Know where your main water shut-off valve is located. If you’ve noticed any specific symptoms — stains, sounds, soft spots in flooring — make a mental note or take a photo. That information helps the plumber start in the right place and saves time.
What are the most common signs that I might need professional leak detection?
Common signs include an unexplained increase in your water bill, the sound of running water when all fixtures are off, warm or damp spots on your floor, low water pressure without an obvious cause, and visible mold or mildew in areas that shouldn’t have moisture. Any one of these is worth a call to a licensed plumber for a proper assessment.
Is slab leak detection different from a standard leak inspection?
Yes. Slab leak detection focuses specifically on pipes running beneath a concrete foundation, which is the standard construction in much of the Tampa Bay area. It typically requires acoustic listening equipment or pressure testing to locate the leak without breaking through the slab unnecessarily. It’s a more targeted process than a general whole-home inspection.
Will the plumber start repairs during the same visit?
That depends on what’s found and what repair it requires. Some minor issues can be addressed the same day. Others — like a slab repair or a repiping job — require planning, materials, and scheduling. A reputable plumber will explain what’s needed and give you time to make a decision. There should never be pressure to approve repair work on the spot.
Can leak detection help with commercial properties, not just homes?
Absolutely. Commercial properties often have more complex plumbing systems, larger pipe runs, and greater consequences when a leak goes undetected. The same professional leak detection methods apply — acoustic equipment, camera inspection, pressure testing — but the scope and documentation requirements may be larger. It’s worth working with a plumber experienced in both residential and commercial systems.
