Blocked drains are a common household nuisance that can lead to unpleasant odours, slow drainage, and even water damage if left untreated. Whether you’re dealing with a minor clog or a serious blockage, knowing how to tackle the problem can save you time and money.

- Boil a kettle of water.
- Pour slowly down the drain in stages.
- Repeat if necessary.
⚠ Caution: Avoid using boiling water on PVC pipes as it can soften them.
2. Try a Plunger
A plunger creates suction that can dislodge clogs in sinks, showers, and toilets.
✔ Best technique:
- Cover the drain completely with the plunger.
- Push down firmly, then pull up sharply.
- Repeat 10-15 times.
3. Baking Soda & Vinegar
A natural, chemical-free solution that breaks down organic blockages.
✔ Method:
- Pour ½ cup of baking soda down the drain.

A drain snake (or auger) is ideal for deeper blockages.
✔ Steps:
- Insert the snake into the drain.

Many blockages occur in the U-bend under the sink.
✔ How to clear it:
