Let’s dive into some quick fixes for minor blockages and explore the signs that indicate it’s time to call a plumber.
With the right knowledge of how to unblock drains, you can tackle common issues and prevent expensive repairs.
What Causes Blocked Drains?
Before tackling a blocked drain, it’s essential to understand the causes. Drain blockages can stem from a variety of issues, some of which are easier to fix than others.
The common culprits include:
- Hair: It’s one of the most frequent causes of blockages in bathroom drains.
- Grease and Soap Scum: Particularly in kitchen sinks, grease and soap residue can accumulate and block your pipes.
- Food Debris: Leftover food and small particles can create a solid barrier inside drains.
- Tree Roots: Roots can infiltrate underground pipes, causing significant blockages.
- Foreign Objects: Items such as wet wipes, sanitary products, and even toys can accidentally block drains.
Knowing what causes blocked drains can help you prevent future blockages and make the right call when it’s time to seek help.
Quick Fixes for Blocked Drains
Not every blockage needs a professional plumber. There are simple, DIY methods that can clear minor blockages and save you from unnecessary plumbing costs.
1. Boiling Water – The Easiest Solution
Best for: Kitchen sinks blocked with grease and soap build-up.
How to do it:
- Boil a kettle of water.
- Slowly pour the boiling water down the drain in stages.
- Wait a few minutes and test if the water drains away.
Note: Avoid using boiling water on PVC pipes or severe blockages.
2. Baking Soda and Vinegar – The Natural Cleaner
Best for: Hair, grease, and minor build-up in bathroom drains.
How to do it:
- Pour half a cup of baking soda into the drain.
- Follow with half a cup of vinegar.
- Cover the drain and let it sit for about 15 minutes.
- Rinse with hot water to clear the debris.
This natural solution creates a fizzing reaction that helps break down the block, deodorises and keeps things fresh.
3. Plunging – The Classic Fix
Best for: Local blockages in sinks, bathtubs, and toilets.
How to do it:
- Use a cup plunger for sinks or a flange plunger for toilets.
- Make sure to create a tight seal around the drain.
- Pump vigorously 10 to 15 times to dislodge the blockage.
Plunging works by creating a vacuum effect that can loosen debris stuck in the drain.
4. Drain Snakes – Getting Deeper into the Pipes
Best for: Blockages caused by hair, solid debris, and deep blocks.
How to do it:
- Insert the drain snake into the blocked drain.
- Rotate gently and push the snake deeper into the pipe.
- Pull back to remove any trapped debris.
A drain snake can reach deeper into your pipes to remove stubborn blockages.
5. Enzyme Drain Cleaners – A Safer Alternative
Best for: Organic waste build-up and preventative maintenance.
How to do it:
- Pour the recommended amount of enzyme cleaner down the drain.
- Let it sit overnight.
- Rinse with warm water the next day.
Enzyme cleaners are a safer alternative to harsh chemicals, breaking down organic material without harming your pipes.
