Leak Detection in Oban

Oban's naturally soft water from Scottish Water corrodes copper and lead fittings over decades, causing pinhole leaks that go unnoticed for months. Many Oban properties lose £1,000+ annually to silent leaks in walls and under floor slabs before detection. Acoustic and thermal imaging pinpoints these hidden water losses in PA34, PA35, PA36, and PA37 postcodes, preventing structural damage and bill shock.

Leak detection in Oban uses thermal imaging and acoustic sensors to find hidden water losses in walls and under concrete slabs. Oban's soft water supply from Scottish Water causes pinhole corrosion in copper and lead pipes, leading to £500–£2,000 annual loss if undetected. Thermal surveys in Oban PA34–PA37 cost £150–£300 and prevent structural damage and bill shock.

Drainage in Oban — what local engineers know

Scottish Water's supply to Oban is naturally soft, which reduces limescale but carries a slightly acidic pH that attacks copper joints and lead pipework. Victorian and Edwardian properties in Oban, especially those with original lead supply pipes, develop pinhole leaks as corrosion accelerates. Argyll and Bute's humid coastal climate exacerbates the problem: water condenses in cold pipes, accelerating internal corrosion. Oban's older properties often have pipes embedded in concrete slab floors, making leaks invisible until structural damage occurs. Thermal imaging and acoustic detection are the only non-invasive methods to locate leaks in Oban's dense Victorian stock without excavation.

  • Soft water supply reduces limescale, but slightly acidic pH can accelerate corrosion of copper fittings and lead joints in older Oban properties
  • Combined sewerage infrastructure — common in older parts of Oban — means foul and surface water share the same pipe, increasing surcharge risk during heavy rainfall
  • Moderate flood risk in parts of Oban — drainage systems near low-lying areas can surcharge after prolonged rain, and sump pump maintenance is advisable
  • With 28% 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.

Illustrative example of typical work

PA35 Victorian Terrace: Detected £800/year Silent Corrosion Leak

Area:
Oban
Service:
Leak Detection

An Oban PA35 homeowner noticed a slow increase in water bills over 18 months but no visible leaks. Thermal imaging detected a pinhole rupture in a copper elbow joint behind the kitchen wall, leaking approximately 2 litres per day. Scottish Water records confirmed acidic soft-water corrosion was the cause. Repair cost £400; the Oban property saved £800+ annually once the leak was capped.

Leak Detection in Oban — FAQs

Why do Oban homes leak from soft water?
Oban's water from Scottish Water is soft and slightly acidic, attacking the internal walls of copper pipes. Over 20–30 years, pinhole corrosion develops in Oban properties, especially where water sits longest (elbows, tees, storage tanks). Lead pipes in Oban built before 1970 also corrode internally, creating slow weeps.
How is a hidden leak found in an Oban property?
Thermal imaging detects temperature differences where water leaks into walls and floors. Acoustic sensors listen for the sound of water escaping under pressure. Both methods pinpoint Oban leaks without excavation or wall removal. Costs typically range £150–£300 for a full-house scan in Oban PA34–PA37 postcodes.
Can Oban's soft water cause other plumbing problems?
Oban's soft water doesn't cause limescale (which is beneficial), but the slight acidity corrodes metalwork faster. After 30 years, Oban homes typically need copper-to-plastic pipe upgrades and lead-removal programmes. Scottish Water publishes soft-water guidance for Oban homeowners.
How do you find a leak without digging?
A combination of acoustic listening sticks, thermal cameras, moisture mapping and inert tracer-gas injection lets us triangulate a leak to within a few centimetres before any opening-up is needed.
Will my insurance cover the cost?
Most UK home-insurance policies include 'trace and access' cover for leak detection. We bill the insurer directly on approved claims.
What leaks can you find?
Mains supply leaks, central heating leaks, hot and cold pipework, underfloor heating, shower-tray leaks, and concealed waste-pipe leaks.
How long does a leak-detection visit take?
Typically 1-3 hours on site, followed by a written report within 48 hours suitable for insurance submission.
