Published Sussex Evidence
This East Sussex investigation shows why the room first suspected should not be treated as the confirmed source. Testing ruled out that bathroom and identified the daily-used ensuite shower room as the supported source area.

Brighton, East Sussex · Bathroom Leak Detection
Water reaching the flat below was traced to an ensuite shower room after the bathroom initially suspected by the client was ruled out.
Scope Of The Finding
The ensuite shower room was identified as the relevant source area, but the exact failed component was not recorded. A report was supplied for the insurer; no repair or insurer decision was documented.
Sussex Enquiries
Location is one part of the booking decision. The team also needs to understand the property, symptoms and investigation requirements before confirming an appointment.
Provide the postcode and property type so the team can review the route and current scheduling.
Explain what you have noticed, the affected system and any checks or previous work already completed.
The team reviews whether the enquiry fits the service scope and which investigation route may be appropriate.
If the location, requirements and schedule align, an appointment can be agreed with the relevant preparation details.
Investigation Methods
No single method answers every investigation question. Engineers select and combine suitable methods according to the symptoms, pipe system, property construction and evidence gathered on site.
Equipment output requires professional interpretation and does not independently guarantee a leak location.
View All Methods And Limitations
Infrared camera surveys help identify temperature patterns linked to hidden moisture and heating faults.
Explore method
Tracer gas testing helps locate concealed pipe leaks beneath floors, behind walls and underground routes.
Explore method
Acoustic equipment can help trace pressurised water leaks using sound from escaping water.
Explore method
Moisture readings help track water movement and support evidence-led investigation findings.
Explore methodSymptom Guidance
These symptoms can have several causes. Use the relevant guide to understand the checks and investigation route rather than treating the symptom as proof of a leak.
Repeated pressure loss can indicate a concealed central heating or underfloor heating leak.
Read guidance 02A sudden increase in usage can point to a hidden mains or supply pipe leak.
Read guidance 03New or spreading damp patches should be investigated before unnecessary access work begins.
Read guidance 04Ceiling stains can be linked to bathroom leaks, pipework faults or escape of water above.
Read guidanceWhy Pro Leak Detection
The investigation route should reflect the property, affected system and evidence—not a fixed equipment checklist.
Reported symptoms, accessible checks and property evidence guide the investigation rather than assumptions about the source.
Methods are selected for the system and conditions, with findings and limitations documented where reporting is required.
An investigation can rule out the area first suspected and identify a different supported source area without inventing an exact failed component.
Sussex FAQs
The directory on this page links to every published Sussex locality page across East and West Sussex. If a location is not shown, provide the postcode so the team can confirm coverage, investigation suitability and scheduling.
Send the property postcode and a short description of the symptoms. Availability depends on the location, investigation requirements and current scheduling.
Enquiries can include concealed plumbing leaks, mains supply pipes, central heating, underfloor heating, bathrooms, waste systems, damp, commercial properties and insurance-related investigation. The appropriate route depends on the property and evidence.
Methods may include thermal imaging, tracer gas, acoustic detection and moisture mapping where suitable. No single method is appropriate for every property or suspected leak.
Not by itself. Water can travel before it becomes visible, so the apparent position may not identify the responsible room or component. The Brighton investigation, for example, ruled out the bathroom first suspected and identified an ensuite shower room as the supported source area.
