Most repeat clogs come from residues — grease, hair, soap scum, and mineral scale — sticking to pipe walls and narrowing the passage. That slowdown traps more debris, creating a rinse-and-repeat clog drainage situation. Underlying issues like a partial sewer line clog, improper pipe slope, hard water scaling, root intrusion, or ageing metal that’s turning into a clogged pipe make it worse. Real relief comes from clearing the full run of pipe and fixing the root cause, not just the symptom at the fixture.
