Progressive Drainage Slowdown Across the House

GooseWashington   |   28 April, 2026

I’ve been dealing with a strange plumbing issue at home that started pretty small but has gradually gotten worse. At first, I just noticed that the kitchen sink was draining a bit slower than usual, so I didn’t think much of it. But over the past week, it has started affecting other drains as well, and now water movement seems inconsistent throughout the house. I’ve tried basic solutions like plunging and store-bought cleaners, but nothing provides lasting improvement. I’m starting to suspect the issue might be deeper in the system. How do you usually determine whether this is a simple clog or something more serious in the main line?
