Leak Detection in Antrim
Soft water with slightly acidic pH is standard across Antrim, accelerating corrosion in copper pipework and lead joints—most problematic in Victorian (14%) and older properties across BT41–44. With 60% of homes built after 1945 and separate sewers standard across town, pinpoint leak detection matters: insurers cover the cost of acoustic and thermal testing once Northern Ireland Water rules out mains faults. Our non-invasive methods avoid unnecessary excavation on ageing infrastructure.
Leak detection in Antrim uses acoustic loggers and thermal imaging to find hidden water leaks in supply pipes and rising mains without excavation. Soft water and acidic pH make copper corrosion common; most leaks qualify for insurer trace-and-access cover.
Drainage in Antrim — what local engineers know
Northern Ireland Water serves Antrim and Newtownabbey with soft water that reduces limescale but creates an acidic environment favouring copper corrosion. Across BT41–44, pin-hole leaks in pre-1960s copper pipework and lead joints are the norm rather than exception, especially in Victorian and Edwardian properties. Leak detection via acoustic loggers and thermal imaging locates these hidden failures without excavation—a significant advantage when ground conditions are poor or property access is restricted. Insurance policies typically cover detection and trace-and-access repair costs once the water company rules out mains faults.
- Soft water supply reduces limescale, but slightly acidic pH can accelerate corrosion of copper fittings and lead joints in older Antrim properties
- Separate sewer system across most of Antrim: 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 Antrim means drain blockages from grease, wipes and root ingress remain the most common call-out reasons

Who's responsible for drains in Antrim?
In Antrim, 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 Antrim and Newtownabbey.
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 Antrim affects where these boundaries typically fall, and our local engineers know the BT41, BT42, BT43 networks well enough to identify ownership quickly.
Leak Detection prices in Antrim
Every Antrim 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.
