Underground Water Leak Located at a Factory in Penang
The bulk meter kept moving with all sub-meter stopcocks closed. A marked leak location was later confirmed by contractor excavation.
01
The problem
During a night inspection at PAC on 3 October 2026, the factory’s bulk water meter continued registering flow after water use had stopped and all sub-meter stopcocks were closed. The main supply remained open.
Approximately 250 litres passed through the meter in four minutes, averaging 62.5 litres per minute. This is the observed inspection flow, not a verified post-repair saving.
02
Our inspection
The scope covered the known domestic supply routes from the bulk meter to all individual meter stands, including connecting branches upstream of the individual sub-meter stopcocks. Pipework downstream of the individual meters was outside the scope.
After a site briefing with the main contractor, a Listening Stick was used to screen accessible branches, followed by a Mikron 3 Pro ground microphone to narrow down the suspected leak location.
Some sections were obstructed by heavy stored materials and could not be inspected. These limitations were recorded in the report.
03
Marking the suspected location
One suspected leak location was marked on the pavement outside the Sheet Metal Department, giving the main contractor a specific area to excavate and verify.
04
What excavation confirmed
On 12 October 2026, the main contractor reported finding a leaking pipe after excavating at the marked location. The follow-up image above shows water escaping from an exposed pipe connection.
Excavation and repair were carried out by the contractor. LeakPinpoint’s work was the investigation and surface marking.
05
Result and follow-up
The marked leak location was confirmed by excavation. Repairs were subsequently reported as completed.
A post-repair bulk-meter check is recommended, with no site water use and all sub-meter stopcocks closed, to establish whether unexplained flow remains. No post-repair meter record was supplied, so this case does not claim that the entire network was confirmed leak-free.
