In this video, we are going to learn how to unblock a sink.

If water is staying in the sink and no longer flows out, your sink is blocked. This is a common problem that has many simple solutions.

If you use chemical products, always wear protective gloves.

To unblock a sink, you will need bicarbonate of soda, salt, white vinegar, boiling water, a chemical unblocker, a plunger, a plumber's snake, a cloth and a bucket.

We are going to show you 4 different techniques to do this.

We are going to begin with a method that uses 100% natural ingredients.

Mix a tablespoon of bicarbonate of soda with a tablespoon of fine cooking salt.

Block the overflow. [not in the french VO]

Pour the mixture into the plug hole.

Immediately add a large glass of white vinegar. Be careful! It will froth up.

Next, pour in a litre of boiling water.

[Put the plug in and - Not in French VO] wait half an hour.

The blockage should be gone.

Before using chemical products, always put on protective gloves.

Pour half a bottle of chemical drain unblocker down the plug hole, keeping it as close to the hole as possible to avoid splashing.

Then leave it to work for 30 minutes.

Chemical drain unblockers are very useful for getting rid of dirt and grease but you should avoid using them regularly as they are not environmentally friendly.

Block the overflow with a cloth so that air cannot escape from it.

Put the plunger over the plug hole, then push it downwards and lift it up to create suction.

Continue until the water can flow out normally.

Put a bowl under the drain.

Unscrew the drain and the clamp ring.

Use a pointed object, such as a screwdriver, to remove the dirt which is blocking the drain.

Insert the plumber's snake into the outflow pipe.

Pull it out along with the debris.

Clean the drain and the joint..

Use the cloth to thoroughly clean the outflow pipe.

Put the compression waste fitting back in place, ensure that the joints are well tightened.

Run the water to check that it drains away.

Your sink is now unblocked and ready to use.
