Real hidden-leak investigations
Real ADI investigations of concealed pipework, including acoustic listening alongside pressure tests and other methods. Each one is written from the engineer’s job record and shows their own photos. Customer names and addresses are left out.
Covers central heating, internal water pipe, cold water, hot water, water supply pipe leaks.
Wall damage in two rooms traced to one hidden pipe
Damp kitchen and bedroom walls led to a failed pressure test. ADI traced the hidden pipework through boxing, opened the kitchen wall and repaired a leaking copper pipe.

A kitchen wall leak found near the ceiling
Water damage in the kitchen accompanied a separate basin leak after bathroom renovation. Moisture readings and an endoscope helped locate a copper pipe fault within the kitchen wall.

Damp at the WC doorway led back to the hallway
Thermal, tracer gas and acoustic checks did not identify this leak. Following moisture through the screed led to a split copper bend beneath the hallway floor.

Three leaks beneath the utility-room floor
A meter kept recording water use with all outlets off. Isolation and pressure tests narrowed the loss to the hot supply; moisture readings and tracer gas led to three buried leaks.

A bathroom-floor leak reached by removing the toilet
Heating pressure dropped within ten minutes. Moisture mapping and tracer gas pointed to the bathroom corner, where opening the floor exposed a leaking 22mm heating pipe.

A hidden connection beneath the kitchen extension
High bills had no visible leak to explain them. Pressure testing confirmed a loss, and tracer gas followed by acoustic checks located a buried connection beneath the kitchen floor.

A second hidden leak found after the first repair area was opened
A constant meter flow led to two faults beneath the kitchen screed. Thermal, moisture, acoustic and tracer gas checks guided access; step testing then revealed a second leak further along the pipe.
