How Do I Clear a Clogged Kitchen Sink?
Goal: clear the blockage you saw on camera, clean the pipe wall, and flush out residue so it doesn’t reform in days.
1.Reassemble (loosely) after inspection: If you removed the trap, reassemble with good washers. Hand-tighten first; you’ll snug it later.
2. Cable the line (mechanical first): Feed a ¼–⅜-in hand auger into the wall stub. Rotate while advancing; don’t ram elbows. When resistance softens, you’re chewing through grease or starch. Pull back, wipe the cable, then pass again to smooth the bore.
3. Hot, soapy flush: Fill the sink with very hot water and a small squeeze of regular dish soap. Pull the stopper to send a pressurized slug through the now-open line. The soap lubricates and carries fines downstream.
4. Camera verify: Look again. You want a round, clean opening with no dangling mats and no “shelf” of sludge. If you still see a greasy band, repeat a gentle cable pass and flush once more.
5. Disposal reset and best practices: Run cold water while operating the disposal (it keeps fats firm so the impellers grind them smaller), then finish with a long hot-water rinse to move everything out of the branch.
6. Maintenance (non-emergency): Enzyme/bio cleaners are for prevention, not for tonight’s plug. Use them per label once the line is mechanically clean.
