Evan from Plumbdog Plumbing heads out to Baldivis after leak detection revealed a hidden leak inside a concrete wall on the home’s main water supply line.

Instead of opening up the wall and causing major damage, the team chose a smarter solution — bypassing the damaged pipe and installing a brand-new water feed to restore the supply safely.

In This Video

•Leak detection identifies a hidden water leak inside the wall
•Isolating and cutting off the damaged section of pipe
•Running a new copper water line up the exterior wall
•Connecting the new pipe through the roof space
•Reconnecting the supply to the hot water service
•Restoring water to the home with no more hidden leaks

By rerouting the main water line externally and through the roof space, the team avoided unnecessary wall demolition while delivering a long-term and reliable plumbing solution.

•The Result

Hidden leak inside the wall successfully isolated

New copper water supply line installed

Water reconnected to the hot water system

No wall demolition required

Home’s water supply restored and leak-free

If you suspect a hidden leak in your walls or main water line, early detection can prevent major damage and costly repairs.

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.

In This Video

•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.
