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.
