Leak Detection in Fishguard
Fishguard properties—especially Victorian and Edwardian homes built on soft-water systems supplied by Welsh Water—are prone to pinhole corrosion in copper fittings and lead joints. The slightly acidic pH of Fishguard's soft water accelerates deterioration of older metalwork. Early leak detection prevents costly water damage and structural issues across SA65, SA66, SA67, and SA68 postcodes.
Leak detection in Fishguard identifies pinhole corrosion in copper pipes caused by Welsh Water's soft, slightly acidic supply (pH ~6.8). Acoustic and dye-tracing methods pinpoint leaks in Victorian properties across SA65–SA68, preventing water damage and combined-sewer saturation.
Drainage in Fishguard — what local engineers know
Fishguard, served by Welsh Water, sits in Pembrokeshire Council's jurisdiction. The town's soft-water supply is beneficial for limescale reduction but carries a hidden risk: acidic pH values attack copper and lead, causing pinhole leaks that develop silently behind walls. Fishguard's older housing stock—24% Victorian, 12% Edwardian—often contains original copper pipework installed when water chemistry was never a concern. Combined sewerage infrastructure in older Fishguard areas compounds the issue: leaking foul pipes soak into garden soil, risking subsidence.
- Soft water supply reduces limescale, but slightly acidic pH can accelerate corrosion of copper fittings and lead joints in older Fishguard properties
- Combined sewerage infrastructure — common in older parts of Fishguard — means foul and surface water share the same pipe, increasing surcharge risk during heavy rainfall
- Ageing infrastructure in parts of Fishguard means drain blockages from grease, wipes and root ingress remain the most common call-out reasons
- With 36% 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 Fishguard?
In Fishguard, 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, Welsh 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 Pembrokeshire.
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 Welsh Water rather than paying for the repair yourself. The combined sewer layout that dominates Fishguard affects where these boundaries typically fall, and our local engineers know the SA65, SA66, SA67 networks well enough to identify ownership quickly.
Leak Detection prices in Fishguard
Every Fishguard 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.
