The Fix-It Playbook — Slow Bathroom Drain Flowchart | Free 1-Page PDF | 2026 Edition

Bathroom sink draining slow or gurgling? Usually free to fix — a bucket and pliers.

Two questions sort it. Is this the only slow drain in the house — several slow drains means the main line. Then clear the pop-up stopper and run a zip-it tool down the drain: flowing again means it was the stopper; still slow means the P-trap, three steps each.

The sheet also carries the slip-nut rule of thumb (hand-tight seals, over-tight cracks), 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 Slow Bathroom Drain ($6) adds the complete troubleshooting table, the under-sink parts diagram, and the hair-catcher trick that prevents most future clogs. All five bathroom guides come together as the Bathroom Repair Kit ($14), and all 24 year-round guides are in the Core Library ($49).
