A blocked sink can be a major inconvenience, causing water to overflow and potentially damaging your property. Fortunately, it's often possible to unblock a sink yourself, saving you time and money on plumbing services.

Here are some simple steps to follow if you have a blocked sink:

1. Clear any visible blockages from the sink.
2. Use a plunger to create suction and break up the blockage.
3. Pour boiling water down the drain to help break up grease and other stubborn blockages.
4. If the blockage persists, try using a drain snake or a chemical drain cleaner.

By following these steps, you can quickly unblock your sink and get back to your daily routine. However, if you're unable to resolve the issue, it's best to seek professional help to avoid causing damage to your pipes.
