The Problem
Staff at a school in Leederville contacted Swan’s Professional Plumbing because they could smell gas in two different areas. On a commercial site with multiple buildings and long buried gas runs, “there’s a smell somewhere” is a genuine detective job.

Our Solution
This is methodical work. Our licensed gas fitters tested the science block: held pressure, no leak. Then we tested at the meter near home economics: pressure drop, leak confirmed.
We then:
- Isolated sections of the line to narrow it down
- Dug up and exposed the connection into the building
- Located the leak at an 80mm adaptor on the buried line
- Cut out the leaking section and replaced it with new copper and fittings
Follow-up testing then showed the old line was still losing pressure elsewhere. Rather than sell the school an endless series of digs, we recommended and quoted a full re-run of the line from the meter to the building.

The Result
The leak found and repaired, and a clear plan for the rest of the line. The total cost of the job was $5,925.70 including GST.
On ageing buried gas lines, that’s the honest answer: fix what’s found, test again, and when the line itself is the problem, say so. You can see more examples in our gas fitting cost guide.
