How to Unclog a Drain Without Calling a Plumber

Before you reach for harsh chemicals or call a plumber, try the simplest methods first. Boiling water alone clears many slow drains caused by soap and grease buildup — pour a full kettle directly down the drain and wait a few minutes. If that does not work, try the baking soda method: pour half a cup of baking soda down the drain, follow with half a cup of white vinegar, cover the drain, and wait 30 minutes. Flush with boiling water.

For hair clogs in the bathroom, a simple drain snake (a plastic strip with barbs) costs almost nothing and pulls out the blockage in seconds. Prevention is the best fix: use drain covers in every sink and shower, and clean them weekly. Most clogs build up slowly over weeks — catching them early means you never face a fully blocked drain.
