Private Residential Property

Residential Water Pipe Leak Investigation in Jitra, Kedah

After moving into a renovated house, the owner received a first monthly water bill of more than RM600. The water meter continued moving even when normal water use had been stopped. The original plumber could not locate the problem, and the situation continued for about a year before another plumber recommended LeakPinpoint.

Section 01

A high water bill after moving in

The property had been renovated before the owner moved in. The first monthly water bill exceeded RM600, and the water meter continued moving when normal water use was stopped.

The original plumber could not locate the problem. After the issue continued for approximately one year, the homeowner considered replacing the entire pipe. Another plumber then recommended LeakPinpoint.

Section 02

Preparing the property for investigation

LeakPinpoint travelled from Penang to Jitra, with an approximate journey time of two hours.

Before the investigation began, normal water use inside the property was stopped. This allowed the water meter and accessible pipeline route to be reviewed under more controlled conditions.

Section 03

Checking the 1-inch HDPE route

We compared sounds along the accessible 1-inch HDPE pipe route and marked a suspected area.

Progressive acoustic checks and ground listening were carried out at several suitable points. The readings were compared along the accessible route rather than relying on one observation.

Section 04

Narrowing and marking the suspected area

After comparing the available listening points, attention was narrowed to a smaller suspected area. A surface mark was placed to guide the customer-appointed plumber during controlled excavation.

The mark was intended to provide a practical excavation starting point and did not represent a guaranteed exact defect position.

Section 05

Excavation exposes the pipe

The customer-appointed plumber opened the investigated area. Water was observed during excavation, and the relevant HDPE pipeline was exposed near the marked location.

An underground pipe defect was exposed and repaired at the investigated location. The exact defect type was not documented.

Section 06

Repair carried out by the customer’s plumber

LeakPinpoint’s role was limited to the underground leak investigation and suspected-location marking.

The customer-appointed plumber carried out the excavation, pipe repair and reinstatement work.

Section 07

Customer feedback after repair.

After the repair was completed, the owner reported that the water meter had returned to normal behaviour.

The post-repair result was reported by the customer.

What This Case Shows

The exact leak rate, complete pipe-route length, exact defect type and exact mark-to-defect distance were not independently documented and are therefore not stated.

The actual pipe condition and repair requirement were confirmed only after excavation.
