Leak Detection in Okehampton
Okehampton's water supply from South West Water is unusually soft—a blessing for limescale but a curse for older copper pipework. The slightly acidic pH of water reaching postcodes EX20–EX23 gradually dissolves the protective oxide layer inside copper tubes, creating tiny pinholes that weep silently for weeks before manifesting as damp walls or rising water bills in Okehampton homes.
Leak detection in Okehampton uses thermal imaging and acoustic listening to find pinhole corrosion in copper pipe caused by South West Water's acidic soft supply. Okehampton properties 15+ years old with hidden copper runs are most at risk.
Drainage in Okehampton — what local engineers know
West Devon Council's historic housing inventory shows Okehampton contains 28% of its stock built before 1960, meaning miles of original copper runs lurk behind walls. South West Water's pH 6.8–7.0 is optimal for drinking but suboptimal for longevity of mineral-intensive pipe materials. The Okehampton area receives 1,600mm annual rainfall, so sub-surface seepage around Okehampton's older foundations masks slow leaks. Separate foul and surface drains mean misconnections in Okehampton properties (e.g. heating system overflow plumbed to the wrong outlet) create detection puzzles that acoustic listening alone cannot solve.
- Soft water supply reduces limescale, but slightly acidic pH can accelerate corrosion of copper fittings and lead joints in older Okehampton properties
- Separate sewer system across most of Okehampton: misconnections (e.g. washing machines plumbed into surface water drains) are a known local issue and can result in environmental enforcement action
- High flood risk in Okehampton: basement and ground-floor properties near watercourses are vulnerable to sewer backflow — non-return valve installation is strongly recommended
- Granite and clay geology around Okehampton creates challenging excavation conditions for drain repairs and makes rodding clearances more complex
- 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.

Who's responsible for drains in Okehampton?
In Okehampton, 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, South West 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 West Devon.
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 South West Water rather than paying for the repair yourself. The separate sewer layout that dominates Okehampton affects where these boundaries typically fall, and our local engineers know the EX20, EX21, EX22 networks well enough to identify ownership quickly.
Leak Detection prices in Okehampton
Every Okehampton 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. 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.
