Leak Detection in Bath
Bath's separate sewer system and older drainage infrastructure mean leak detection here is different from standard urban areas. With 45% of Bath properties built before 1940 — many with salt-glazed clay pipes and lead-solder copper joints — corrosion-driven pinholes are the most common hidden leak we find. Using acoustic loggers and thermal imaging across BA1–BA4, we locate leaks without excavation.
Leak detection in Bath uses non-invasive acoustic loggers, thermal imaging, and tracer gas to find hidden water leaks without excavation. Ideal for Victorian properties where copper corrosion is common due to South West Water's soft water supply. Insurance covers trace-and-access once the source is identified.
Drainage in Bath — what local engineers know
South West Water supplies Bath and North East Somerset with soft water, which sounds beneficial but the slightly acidic pH actually accelerates corrosion in the copper and lead-solder fittings common in Victorian and Edwardian properties across BA2 and BA3. High flood risk zones in Bath mean basement properties are especially vulnerable to sewer backflow; leak detection becomes critical before water damage spreads. Granite and clay geology here complicates excavation, so non-invasive thermal and acoustic testing saves both cost and disruption during diagnosis.
- Soft water supply reduces limescale, but slightly acidic pH can accelerate corrosion of copper fittings and lead joints in older Bath properties
- Separate sewer system across most of Bath: 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 Bath: basement and ground-floor properties near watercourses are vulnerable to sewer backflow — non-return valve installation is strongly recommended
- Granite and clay geology around Bath 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 Bath?
In Bath, 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 Bath and North East Somerset.
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 Bath affects where these boundaries typically fall, and our local engineers know the BA1, BA2, BA3 networks well enough to identify ownership quickly.
Leak Detection prices in Bath
Every Bath 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.
