Blocked sinks and shower drains are very common, and you can usually clear them yourself without calling a plumber. The key is to start simple and only move to stronger methods if needed.
Start with the obvious (and often effective)
1. Boiling water + washing-up liquid
- Pour some washing-up liquid down the drain.
- Follow with a kettle of boiling water.
- This helps break down grease and soap buildup.
Physical methods (best for hair and gunk)
2. Plunger
- Use a sink or cup plunger (not a toilet one if possible).
- Cover the overflow hole with a cloth for better suction.
- Pump firmly several times.
3. Drain snake / hair remover tool
- Cheap plastic tools work really well for showers.
- Pull out hair, soap scum, and debris (it won’t be pretty, but it works).
Natural cleaning method
4. Baking soda + vinegar
- Pour about ½ cup baking soda down the drain.
- Add ½ cup vinegar.
- Let it fizz for 10–15 minutes.
- Flush with hot water.
Good for mild blockages and smells, but not strong enough for serious clogs.
Check the trap (U-bend)
5. Clean the U-bend (sink only)
- Put a bucket underneath.
- Unscrew the pipe (usually hand-tightened).
- Remove and clean out debris.
- Reattach tightly.
This is one of the most effective fixes for kitchen sinks.
Stronger options (use carefully)
6. Drain cleaner (chemical)
- Works on tougher clogs but can damage pipes if overused.
- Always follow instructions and avoid mixing products.
When to call a plumber
- Water drains very slowly even after trying everything
- Multiple drains are blocked (could indicate a bigger pipe issue)
- You hear gurgling noises or get bad smells regularly
Quick prevention tips
- Use a hair catcher in showers
- Don’t pour grease down the sink
- Flush drains with hot water weekly
