How To Find A Plumbing Leak

How To Find a Plumbing Leak: Essential Steps for Property Owners and Facilities Managers

Plumbing leaks can be a silent but costly problem for property owners, facilities managers, and businesses. Whether you manage a commercial building, residential block, or industrial facility, undetected leaks can lead to water damage, structural deterioration, and increased maintenance costs. For those responsible for building upkeep—especially in hard-to-reach areas—identifying a leak early is crucial. At Corded.uk, we understand the unique challenges of maintaining building exteriors, roofs, and high-level structures, and we know that finding a plumbing leak is often the first step toward effective repairs and long-term preservation.

Below, we outline a practical guide to finding plumbing leaks, with a focus on scenarios where leaks may occur in elevated or difficult-to-access locations.

1. Recognise the Signs of a Plumbing Leak

Leaks aren’t always obvious, especially in large or multi-story buildings. Be alert for the following indicators:

– Unexplained water stains on ceilings, walls, or exterior façades
– Peeling paint or wallpaper, often caused by moisture behind surfaces
– Dripping sounds or running water when fixtures are off
– Mould or mildew growth in unexpected places
– Unusually high water bills without increased usage
– Damp patches on floors, especially near walls or columns
– Efflorescence (white, powdery deposits) on brickwork or masonry

2. Check Accessible Plumbing Fixtures

Begin your search at the source: inspect taps, toilets, sinks, and visible pipework. Look for:

– Leaks or drips under basins and behind toilets
– Pooling water around appliances such as washing machines or dishwashers
– Loose fittings or corroded joints

For multi-storey buildings, check communal areas and plant rooms, as leaks in these locations can affect multiple units.

3. Inspect High-Level and Hard-to-Reach Areas

In many cases, leaks originate in places that are difficult to access—such as rooftops, gutters, service risers, or external walls. These are often the areas where Corded.uk’s rope access services provide a significant advantage over traditional methods.

– Rooftop plumbing: Flat roofs, parapets, and roof-mounted plant rooms are prone to leaks, especially where pipes penetrate roofing membranes.
– Gutters and downpipes: Blocked or damaged gutters can cause water to overflow and penetrate the building envelope.
– External pipework: Look for signs of staining, corrosion, or moss growth on walls, which may indicate a persistent leak.

Using rope access, technicians can safely and efficiently examine these areas without the need for scaffolding or cherry pickers—minimising disruption to building occupants and surrounding areas.

4. Use Water Meter Testing

A simple but effective way to check for hidden leaks is to use your building’s water meter:

1. Turn off all water-using appliances and fixtures.
2. Note the water meter reading.
3. Wait at least one hour (ensure no water is used during this time).
4. Check the meter again. If the reading has changed, there is likely a leak somewhere in the system.

This test is particularly useful in large or complex buildings where a leak may not be visible.

5. Employ Moisture Detection Tools

For more precise leak detection, consider using:

– Moisture meters to identify damp within walls or floors
– Infrared cameras to spot temperature differences caused by water
– Acoustic listening devices to detect the sound of water escaping from pipes

Professional maintenance teams—like those at Corded.uk—often use these tools when surveying high-level façades, roofs, or inaccessible service ducts.

6. Call in the Experts for At-Height Leak Investigation

If you suspect a leak in a hard-to-reach or dangerous location, do not attempt to access it yourself. Rope access specialists are trained to work at height safely, following strict safety protocols and using advanced equipment. Corded.uk’s technicians can:

– Conduct thorough inspections of external walls, roofs, gutters, and risers
– Identify the source of leaks even in complex environments
– Carry out repairs, sealing, or maintenance with minimal disruption

This approach is not only safer but often more cost-effective and efficient than erecting scaffolding or using heavy machinery.

7. Prevent Future Leaks with Regular Maintenance

Once a leak is found and repaired, regular inspections are key to preventing recurrence. Schedule periodic checks of:

– Roofs and gutters, especially after severe weather
– External plumbing and drainage systems
– Building façades and windows

Rope access teams can provide ongoing maintenance, cleaning, and minor repairs, ensuring your property remains watertight and structurally sound.

Conclusion

Finding a plumbing leak can be challenging, particularly in large or high-rise buildings. By understanding the signs of a leak, checking accessible fixtures, and enlisting the help of rope access professionals for difficult areas, property owners and facilities managers can protect their assets and avoid costly damage. Corded.uk offers a safe, efficient, and cost-effective solution for leak detection and repair in even the most inaccessible locations—helping you maintain your property with confidence.
