If your water bills rise unexpectedly without increased usage, it could indicate a hidden underground leak wasting water beneath your property.
causes of leakage
Tree Root Invasion
Tree roots naturally seek out moisture and can infiltrate joints or cracks in underground pipes, eventually expanding and causing breakage.
Poor Installation or Workmanship
Pipes that were poorly installed or not buried to the correct depth may shift, break, or collapse under pressure.
Ground Movement
Soil shifting from construction work, heavy rains, or temperature fluctuations can cause strain on buried pipes, resulting in cracks or disconnections.
Water Pressure Issues
Excessively high water pressure can weaken pipe joints and connections, leading to underground leaks.
Old or Corroded Pipes
Aging pipelines made from galvanized steel, iron, or other non-resistant materials are prone to corrosion and leakage over time.
External Damage
Renovation or excavation work may accidentally hit or dislodge buried pipes.
Advanced Leak Detection Tools We Use
Locating a hidden leak is not guesswork—it requires a combination of expertise, experience, and the right equipment. At All Plumbing.SG, we invest in modern detection tools that allow us to locate leaks without unnecessary hacking or damage.
🔹 Thermal Imaging Cameras
These infrared cameras detect temperature changes caused by evaporating water. Cool patches on walls, floors, or ceilings often indicate active leaks.
🔹 Acoustic Leak Detectors
Using ultra-sensitive microphones, we detect the sound of water escaping from pressurised pipes—even when buried deep within concrete or soil.
🔹 Pressure Testing
By isolating pipe sections and monitoring pressure loss, we can identify leaking points in water supply lines quickly and accurately.
🔹 Pipe Inspection Cameras (CCTV)
Flexible waterproof cameras allow us to explore the inside of pipes—especially floor traps, waste pipes, and vertical stacks—to locate cracks, joint failures, or foreign objects.
🔹 Tracer Dye Testing
For wet areas like toilets or balconies, coloured dye helps trace hidden water paths and confirms leak locations in tiled or concrete surfaces.
Moisture Meters and Wall Scanners
These electronic tools detect abnormal moisture levels in materials such as tiles, concrete, plaster, or drywall, helping us locate saturated areas caused by concealed leaks.
This technology-first approach ensures fast, precise results. It also reduces disruption and saves money on unnecessary hacking.
Types of Leaks We Specialise In
Our concealed and underground leak detection services include:
🔹 Wall pipe leaks (kitchen, bathroom, utility room)
🔹 Ceiling and upper-floor pipe leaks (HDB, condo stack pipes)
🔹 Toilet or bathroom concealed trap leaks
🔹 Balcony waterproofing or seepage issues
🔹 Leaking concealed shower or basin pipes
🔹 Underground garden pipe leaks (landed homes)
🔹 Slab or foundation leaks from aged or corroded piping
🔹 Floor trap and underground drainage pipe leaks
Whatever the source, we’ll locate it quickly, and fix it thoroughly—without guesswork or unnecessary hacking.
Full Leak Detection & Repair Process
When you contact AllPlumbing.SG for concealed or underground leak detection, we follow a systematic and professional process to ensure the problem is resolved completely.
1. Site Assessment
We conduct a visual inspection and ask key questions about water usage, history of leaks, or recent renovations to determine possible sources.
2. Leak Detection
Our plumbers deploy detection equipment to localise the leak source accurately without damaging walls or floors unnecessarily.
3. Damage Isolation
Once the leak is found, we isolate the affected section to prevent further water loss or structural impact.
4. Pipe Repair or Replacement
Depending on the leak type and severity, we may:
🔹 Repair cracked or burst pipes
🔹 Replace corroded fittings
🔹 Seal leaking joints
🔹 Reconnect pipe segments
We use high-quality materials like copper, uPVC, stainless steel, or PPR pipes to ensure durability.
5. Minimal Hacking with Restoration
Only the affected section is accessed—minimising surface damage. Once the repair is complete, we restore tiles, walls, or flooring to their original condition.
6. Post-Repair Testing
After the fix, we retest the system using pressure or thermal tools to confirm that the leak is 100% resolved.
Preventing Future concealed/Underground Pipe Leaks
While some underground leaks are unavoidable, you can minimize risks with proactive plumbing care:
🔹 Schedule regular pipe inspections
🔹 Use corrosion-resistant pipe materials
🔹 Ensure proper soil grading during landscaping
🔹 Install pressure regulators to manage high water pressure
🔹 Avoid planting trees near major pipe routes
Let our team help you maintain a leak-free plumbing system with regular checks and maintenance plans.
testimonials
You may notice signs such as unusually high water bills, damp or muddy spots in your yard, low water pressure, or the sound of running water when taps are off. A professional inspection can confirm the source of the leak.
Not always. Depending on the location and severity, non-invasive techniques like trenchless repair or pipe relining can fix the issue with minimal disruption to your property.
Minor repairs may take a few hours, while more complex cases could require one to two days. The timeline depends on the pipe’s depth, material, and accessibility.
Generally, leaks within your property boundaries are the homeowner’s responsibility, while those outside (on public land) fall under the utility company’s care.
