What causes the problems electronic leak detection finds?

Acoustic detection is used when a leak is suspected but nothing is visible. Most of the leaks it finds under Pflugerville slabs come from a few common causes.

• Copper lines wearing thin where they rub against concrete or rebar
• Joints loosened by slab movement in clay soil
• Pinholes from years of hard, mineral-rich water
• Nail or screw damage from past remodeling work

Which warning signs matter most?

What should you expect?

Acoustic detection works best when the house is quiet. Providers may ask you to turn off fans, the fridge ice maker and irrigation during the test so background noise does not mask the leak.

How can you prevent it?

• Check your water meter with everything off every few months
• Keep house water pressure in a normal range; very high pressure strains pipes
• Note any new floor cracks after big weather swings
• Tell remodeling crews where supply lines run before they drill or nail

How does electronic leak detection find a leak you cannot see?

Water escaping a pressurized pipe makes noise. At a pinhole or cracked joint, the water rushes out and creates a hiss or vibration that travels through the pipe, the soil and the concrete. Acoustic detection uses ground microphones and amplifiers to pick up that sound through the floor.

The technician first isolates the lines, often by shutting off the water heater supply or specific valves, to learn whether the leak is on the hot side, the cold side or the main line. They then trace the likely pipe path across the slab and listen at points along it. The sound is loudest right above the leak, and the spot is marked on the floor.

Many providers pair acoustic listening with other tools. A line tracer can send a signal down the pipe so its path can be followed from above. A pressure gauge confirms the line is losing pressure. Thermal imaging can show a warm patch when a hot line is leaking. Using more than one tool narrows the search and makes the mark more reliable.

What tools might the technician use?

How should you prepare for the visit?

• Know where your main shut-off and water heater valves are
• Clear furniture and rugs from the area you suspect
• Turn off appliances that run water, such as the dishwasher, washer and ice maker
• Keep pets and children in another room; the work needs quiet
• Have recent water bills handy if usage has jumped
• Note any warm spots, damp baseboards or cracks you have seen

The quieter the house, the better. HVAC fans, pool pumps and even a busy street can add background noise, so the technician may ask to turn equipment off for a short time.

What limits electronic detection?

Acoustic detection works best on pressurized water lines. It is less useful for drain lines, which are not under pressure and are better checked with a camera. Very thick tile, deep pipe runs and noisy surroundings can also make leaks harder to hear.

No tool can see through concrete. The mark on the floor is an informed estimate, usually close enough to plan a small, targeted opening. Ask the provider how confident they are in the mark and what they will do if the pipe is not exactly where expected when it is opened.

What should the detection report include?

A good report lists which lines were tested, which held pressure and which did not, the methods used and where the leak was marked. It may include photos of the mark and notes on the pipe material. Keep this report. It is what a repair provider works from, and it can help with an insurance claim.

How long does electronic leak detection take?

Most homes take a few hours. Simple cases, where one line fails a pressure test and the leak is loud, can be marked quickly. Larger homes, quiet leaks and long pipe runs take longer, because the technician has to trace each line and listen at more points. If tracer gas is needed, add time to drain and fill the line. Ask for a rough time window when you book so you can plan to be home, and ask whether the price is fixed or depends on time spent.
