Petrol garage: 15 litres a minute lost underground
The meter kept moving with every outlet shut. Tracer gas led to a flooded chamber where several mains leaks were repaired.
Three published ADI investigations: a petrol garage losing water underground, a leaking school supply and continuous consumption at hospitality premises.
The meter kept moving with every outlet shut. Tracer gas led to a flooded chamber where several mains leaks were repaired.
A hissing classroom and saturated ground led to a leaking desk-tap supply. The school chose to cap the branch rather than excavate.
The meter showed continuous consumption. Testing found a faulty urinal flush control and dripping fixtures, with no concealed pipe leak indicated.
Photographs and investigation details come from ADI Leak Detection’s published case studies. Each write-up records what was found and whether repairs were completed.
