Emergency Plumber in Caerphilly
Caerphilly has a significant number of older homes — many were built before 1920 with Victorian and Edwardian construction. These run on combined sewerage, which means foul and surface water share the same pipe. CF83 and CF84 areas especially see burst pipes and blockages because Welsh Water's soft supply corrodes the old copper and lead pipework faster. When one pipe fails during heavy rain, the whole system can back up.

Drainage in Caerphilly — what local engineers know
Welsh Water manages supply and sewerage for Caerphilly under Cardiff Council. The combined drain network in older postcodes like CF83 and CF84 means foul and surface water share the same pipe — heavy rain overloads it easily. Though Caerphilly's flood zone is Low overall, a significant share of homes predate 1920 with salt-glazed clay and lead-solder pipework that corrodes under soft water. Root ingress and grease blockages are the norm in these old systems.
- Soft water supply reduces limescale, but slightly acidic pH can accelerate corrosion of copper fittings and lead joints in older Caerphilly properties
- Combined sewerage infrastructure — common in older parts of Caerphilly — means foul and surface water share the same pipe, increasing surcharge risk during heavy rainfall
- Ageing infrastructure in parts of Caerphilly means drain blockages from grease, wipes and root ingress remain the most common call-out reasons
- With a significant share 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 Caerphilly?
In Caerphilly, 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 Cardiff.
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 Caerphilly affects where these boundaries typically fall, and our local engineers know the CF83, CF84, CF85 networks well enough to identify ownership quickly.
