Leak Detection in Perth
Hidden leaks in Perth properties often go undetected until water bills spike or structural damage emerges. Perth's soft-water supply and combined sewerage system create unique diagnostic challenges—acidic water gradually corrodes copper joints and lead fittings, while shared foul/surface pipes can mask the source of leaks. In PH2 and PH3 postcodes, Victorian properties frequently develop pin-hole corrosion in copper runs beneath walls.
Leak detection in Perth uses acoustic sensors to pinpoint hidden water loss in pipes without excavation. Scottish Water-supplied properties in PH1–PH4 often develop corrosion-driven leaks due to soft-water chemistry. Professional detection saves Perth homeowners hundreds in wasted water annually.
Drainage in Perth — what local engineers know
Perth and Kinross Council oversees drainage standards across the city, while Scottish Water manages water supply and sewage infrastructure. Perth's 10,000 residents rely on combined sewers in older residential zones—a factor that complicates leak diagnosis, as surface-water ingress into foul pipes can mimic internal leaks. The slightly acidic pH of Scottish Water's supply accelerates pinhole corrosion in copper and dezincification in brass fittings, making Perth homes more susceptible to slow leaks than areas served by soft-water suppliers.
- Soft water supply reduces limescale, but slightly acidic pH can accelerate corrosion of copper fittings and lead joints in older Perth properties
- Combined sewerage infrastructure — common in older parts of Perth — means foul and surface water share the same pipe, increasing surcharge risk during heavy rainfall
- Moderate flood risk in parts of Perth — drainage systems near low-lying areas can surcharge after prolonged rain, and sump pump maintenance is advisable
- With a significant share of properties built before 1920, salt-glazed clay drainage and lead-solder copper pipework are common — pipe collapse, root ingress and joint failure are recurring call-out drivers.

Who's responsible for drains in Perth?
In Perth, responsibility for a blocked or damaged drain depends on where the fault sits. As a homeowner you are responsible for the drains within your property boundary that serve only your home. Since the 2011 private sewer transfer, Scottish Water is responsible for shared sewers and lateral drains beyond your boundary — even where they run under private land. Road gullies and highway drainage are maintained by Perth and Kinross.
This matters because it determines who pays. If our engineer's CCTV inspection shows the fault is in a shared sewer, we'll tell you — and you can report it to Scottish Water rather than paying for the repair yourself. The combined sewer layout that dominates Perth affects where these boundaries typically fall, and our local engineers know the PH1, PH2, PH3 networks well enough to identify ownership quickly.
Leak Detection prices in Perth
Every Perth job is quoted as a fixed price before work starts — what we quote is what you pay, with no call-out fee for providing the quote. However, the final price depends on access (an external inspection chamber is quicker than internal-only access), the pipe material and condition , and how established the blockage or fault is. Request your free quote and we'll confirm the price and your engineer's ETA in the callback.
In summary, Leak Detection in Perth is backed by a 12-month workmanship guarantee. Furthermore, every job includes a written completion report. Consequently, you have full documentation if the same fault recurs.
