Frequently Asked Questions About Water Leak Detection
What is water leak detection?
Water leak detection is the process of identifying the source and location of water escaping from plumbing systems within a property or underground. This is often done using non-invasive techniques to avoid unnecessary damage.
How do you detect a water leak?
At Speedy Jet Plumbing, we use a range of advanced techniques including acoustic listening equipment, thermal imaging cameras, tracer gases, and moisture meters to accurately pinpoint the location of hidden leaks with minimal disruption.
What are the common signs of a water leak?
Look out for unexplained high water bills, drops in water pressure, damp or discoloured patches on walls or ceilings, musty odours, the sound of running water when appliances are off, or lush/soggy patches in the garden.
Water pressure dropped. Do I need water leak detection?
A sudden or significant drop in water pressure can be a key indicator of a water leak, as water is escaping the system before it reaches your taps. While other issues can cause low pressure, a leak is a common culprit that requires investigation, making leak detection a necessary step.
Can a water leak cause lower water pressure?
Yes, absolutely. When water leaks from a pipe, it reduces the volume and pressure of water flowing through the rest of the system. A noticeable drop in pressure, especially across multiple fixtures, is a strong sign that a leak may be present.
Why is water leak detection necessary?
Water leak detection is necessary to prevent significant property damage (structural issues, mould), avoid wasting water, reduce inflated water bills, and maintain adequate water pressure. Early detection saves you money and prevents long-term problems.
Why have I lost water pressure?
Loss of water pressure can be caused by several factors, including issues with your water provider’s supply, blockages in your pipes, faulty fixtures, or importantly, a hidden water leak. Professional leak detection can help determine if a leak is the reason for your low pressure.
How complex is a water leak detection service?
The complexity varies depending on the location and nature of the leak. Simple leaks might be quickly found, while those hidden underground or within complex building structures require advanced equipment and expertise to accurately locate without causing damage. Our service is designed to handle varying levels of complexity efficiently.
Is it difficult to perform a water leak detection?
For a homeowner without the right tools and expertise, finding a hidden leak can be very difficult, often leading to unnecessary damage. Professional water leak detection requires specialist equipment (like acoustic sensors and thermal cameras) and trained technicians who understand how to interpret the data. It’s a job best left to experts like Speedy Jet Plumbing.
How much does water leak detection cost?
The cost can vary depending on the complexity and location of the leak, and the methods used for detection. We recommend contacting us for a specific quote, but investing in professional detection is often far less expensive than repairing damage caused by an undetected leak.
Will detecting a water leak cause damage to my property?
Our advanced leak detection methods are designed to be as non-invasive as possible. We aim to locate the leak precisely using technology like thermal imaging and acoustic sensors, minimising the need for disruptive digging or breaking through walls.
How quickly can you attend to a suspected water leak?
We understand that a suspected leak is often an urgent issue. Speedy Jet Plumbing is committed to providing a rapid response across London. Please call us directly to discuss your situation and our availability.
Are your leak detection services available across London?
Yes, Speedy Jet Plumbing provides comprehensive leak detection services throughout London, covering a wide range of areas and postcodes.

Undetected leaks, whether a dripping tap or a hidden pipe burst, can cause a surprising amount of damage over time. From structural issues and mould growth to increased water consumption and lower water pressure, the consequences can be far-reaching. That’s where professional plumbing leak detection becomes invaluable.
Recognising the Signs of a Hidden Water Leak
Many leaks start small and out of sight, making them difficult to spot. However, there are several signs that could indicate a hidden water leak on your property:
- Unexplained Increase in Water Bills: If your water usage habits haven’t changed but your bills are rising, a hidden leak could be the culprit.
- Falling Water Pressure: A sudden drop in water pressure from your taps or shower can indicate water escaping somewhere in your system.
- Damp Patches or Staining: Discoloured or damp areas on walls, ceilings, or floors, or peeling paint or wallpaper, are strong indicators of moisture accumulation from a leak.
- Musty or Mouldy Odours: Persistent musty or earthy smells, particularly in enclosed spaces like cupboards, can signal hidden dampness and potential mould growth due to a leak.
- Sounds of Running Water: Hearing the sound of running or dripping water when no taps or appliances are in use is a significant sign of a leak within your pipework.
- Lush or Soggy Patches in the Garden: For external leaks, an unusually green or waterlogged area in your garden, even during dry periods, could indicate an underground pipe leak.
- Cracks in Walls or Floors: In severe cases, long-term leaks can affect the foundation of your property, leading to cracks.
Ignoring these signs can lead to more extensive damage and costly repairs down the line.

Our Advanced Leak Detection Process
Speedy Jet Plumbing utilises a range of non-invasive and advanced techniques to pinpoint the exact location of leaks, even those hidden beneath floors or behind walls:
- Acoustic Leak Detection: Using highly sensitive listening equipment, our engineers can detect the sound of water escaping from pipes, even underground.
- Thermal Imaging: Infrared cameras can identify subtle temperature differences caused by water leaks, helping to locate hidden moisture.
- Tracer Gas Detection: A safe, non-toxic gas is introduced into the pipework. This gas escapes at the leak point and can be detected by specialist equipment.
- Moisture Meters: These tools measure the moisture levels in building materials, helping to identify damp areas caused by leaks.
- Pressure Testing: By isolating sections of your plumbing system and monitoring pressure changes, we can determine if a leak is present and narrow down its location.
This multi-faceted approach ensures we can efficiently and accurately locate leaks in various plumbing systems, from simple dripping taps to complex underground pipe issues.
