Slow-draining sinks, foul smells from plugholes and water pooling around external drains usually indicate a blockage. Plumber Croydon clears waste traps, soil pipes and manholes using rods, cutters or jetting where appropriate. Recurring problems may need CCTV inspection to locate collapsed sections or root ingress before any excavation. Preventive drain care helps many Croydon properties avoid messy call-outs after heavy rain.
