Does a blocked drain really need replacing?
A single blockage might be paper or accumulated debris. A drain that blocks every few months deserves more questions. The important point is whether there is a restriction, damaged joint, poor fall or recurring root ingress — and what the evidence shows.
A drain camera can help with that investigation, but a recommendation to replace the pipe should still be justified by the recorded defect.
