Plumbing Repairs in Caerphilly
Over a third of Caerphilly's properties were built before 1920, meaning lead supply pipes, brass compression fittings and soldered copper joints are still in use. Combined sewerage runs through the area, which increases pressure on drain systems. We handle leaking pipes, failing valves and running toilets across CF83, CF84, CF85 and CF86 with fixed pricing and no guesswork.
Caerphilly's Victorian and Edwardian housing stock relies on aging copper fittings and lead solder joints vulnerable to Welsh Water's soft acidic supply. Leaking pipes, dripping taps and running toilets are common. We fix these with fixed pricing across CF83–CF86.
Drainage in Caerphilly — what local engineers know
Welsh Water supplies Caerphilly with soft water—good news for limescale, bad news for corrosion. The slightly acidic pH accelerates wear on older copper pipework and lead solder joints, particularly in Victorian and Edwardian terrace properties that dominate many roads. Cardiff Council oversees much of the drainage infrastructure here, which sits on combined sewers. This means foul and surface water share pipes, increasing blockage risk during heavy rainfall. Root ingress, grease buildup and wipe accumulation in older clay drains (common before 1950) are the most frequent problems.
- 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.
