Leak Detection in Larne
Water leaks in Larne properties are often caused by corrosion of copper and lead pipework—a particular risk where Northern Ireland Water's soft supply is slightly acidic. Early detection prevents costly water damage and environmental enforcement in Larne's separate sewer system. We locate leaks in Larne using advanced acoustic and thermal imaging before they become emergencies.
Leak detection in Larne uses acoustic and thermal imaging to locate hidden water leaks in copper pipework, especially in Victorian properties affected by the town's slightly acidic soft water supply. Early detection prevents corrosion damage and enforcement issues in Larne's separate sewer system.
Drainage in Larne — what local engineers know
Larne's soft water supply (managed by Northern Ireland Water) has a low pH that gradually corrodes older copper fittings and lead joints, especially in the 14% of Larne's Victorian housing stock. The separate sewer system across Larne (overseen by Mid and East Antrim Council) means misplaced discharge can trigger enforcement action—making early leak detection critical. Victorian and Edwardian properties in BT40 postcodes are at highest risk of pin-hole leaks in copper, often invisible until water damage appears.
- Soft water supply reduces limescale, but slightly acidic pH can accelerate corrosion of copper fittings and lead joints in older Larne properties
- Separate sewer system across most of Larne: misconnections (e.g. washing machines plumbed into surface water drains) are a known local issue and can result in environmental enforcement action
- Ageing infrastructure in parts of Larne means drain blockages from grease, wipes and root ingress remain the most common call-out reasons

Who's responsible for drains in Larne?
In Larne, 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, Northern Ireland 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 Mid and East Antrim.
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 Northern Ireland Water rather than paying for the repair yourself. The separate sewer layout that dominates Larne affects where these boundaries typically fall, and our local engineers know the BT40, BT41, BT42 networks well enough to identify ownership quickly.
Leak Detection prices in Larne
Every Larne 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.
