The Fix-It Playbook — Clogged Kitchen Sink Flowchart | Free 1-Page PDF | 2026 Edition

Kitchen sink slow or backed up? Skip the chemicals.

Two questions sort it. Is it only this sink backing up — several fixtures together means the main line. Then: is one bowl slow, or do both back up together? That sends you to the strainer and branch or the shared P-trap, three steps each.

The sheet also carries why plunging 'fails' on a double sink (block the other bowl), and a plain line on when to stop and call a pro.

One page. Print it or keep it on your phone. Free instant PDF download, yours to keep.

If the tree sends you deeper: How to Clear a Clogged Kitchen Sink ($6) adds the complete symptom-to-fix troubleshooting table, the tool list, and the tricks that keep grease clogs from coming back. All five kitchen guides come together as the Kitchen Repair Kit ($14), and all 24 year-round guides are in the Core Library ($49).
