Leak Detection

Evan and Dan from Plumbdog Plumbing return to a property after previously pinpointing a hidden water leak beneath a long driveway.

After completing leak detection a few days earlier, the team identified the exact location of the underground pipe that had split — buried beneath pavers and surrounded by several other underground services.

Accessing the pipe required carefully lifting the driveway pavers and excavating deep into the trench to expose the damaged section without disturbing the nearby services.

•Leak detection and pinpointing the burst pipe location
•Lifting driveway pavers to access the underground water line
•Excavating nearly 1 metre deep around multiple services
•Repairing the damaged section of water pipe
•Reinstalling pavers and restoring the driveway

Working carefully around several services running through the same trench, the team successfully exposed the pipe, completed the repair, and reinstated the driveway.

The Result

Burst underground pipe located and repaired

Water supply restored to the property

Driveway pavers lifted and carefully reinstated

Area cleaned and returned to original condition

Leak fully resolved

If you notice unexplained water loss, wet patches, or rising water bills, a hidden underground leak could be the cause.

Evan from Plumbdog Plumbing returns to a property in Perth after earlier leak detection traced a hidden water leak to underneath the client’s garage floor slab.

To access the damaged pipe, the team carefully cuts the concrete slab, excavates the area below the floor, and exposes the underground pipework causing the problem.

In This Video

•Leak detection pinpointing a hidden leak under the garage
•Cutting the concrete slab to access the pipework
•Excavating beneath the floor to expose the damaged line
•Finding a snapped polybutylene pipe causing the leak
•Installing a repair section and offsetting the pipe with elbows to reduce future stress
•Re-concreting the slab and restoring the area

Older polybutylene pipes can become brittle over time, particularly when they’re under constant pressure or stress within a concrete slab. By adding an offset during the repair, the new section reduces strain on the pipe and helps prevent future failures.

The Result

Hidden leak under the garage successfully located

Damaged polybutylene pipe removed and repaired

Pipework offset to reduce stress and future cracking

Concrete slab reinstated and area restored

Water supply running leak-free again

If you notice unexplained water usage, damp areas, or pressure loss, a hidden leak under your slab could be the cause.

Dan from Plumbdog heads out to Caversham to repair a leaking reticulation main supply line feeding the irrigation solenoids.

After a previous inspection found a leak in the main supply, the solution was to replace the damaged supply pipe and install a new duo valve with backflow protection. This keeps the irrigation system running properly while also protecting the home’s potable water supply.

Working in 35°C Perth heat, Dan digs a trench, removes the old pipework, and installs a much cleaner and safer setup.

•Tracking down a leaking reticulation main supply
•Digging a 300 mm trench to access the irrigation line
•Installing a new duo valve with proper backflow protection
•Reconnecting the existing irrigation solenoids
•Backfilling and tidying the entire irrigation setup

“Fixing the supply properly and installing the right backflow protection keeps the irrigation system working — without risking contamination of the main water supply.”

The Result

•Main irrigation supply leak repaired
•New duo valve installed for safe operation
•Backflow protection added for compliance
•Irrigation solenoids reconnected and functioning
•Site backfilled and restored neatly

The result is a neat, compliant, and leak-free irrigation system ready to keep the garden watered without wasting water.
