Why is my sink blocked? Follow this step by step guide
If you’re running your taps and the sink is ending up looking like a mini bath, taking ages to drain, or perhaps refusing to drain all together, there’s a good chance you’ve got a blockage on your hands. A common problem, with a number of causes, follow this step by step guide to source the problem and get things running smoothly again.
Step One: Preparation
You will need:
- Protective glasses and gloves
- Baking soda and white vinegar
- Dish cloths
- A plunger
- A bucket or plastic bowl
Step Two: Cleaning out the plughole
To begin, you will need to first unscrew the plug, then inspect the plughole and clean out any dirt or debris.
Step Three: Sealing the plughole and overflow
Fill the sink with water so that the plughole is covered, ensuring an airtight seal for the plunger. Block the overflow hole with a dish cloth.
Step Four: Plunging
Place the plunger tightly over the plughole and plunge several times. You may need to hold the dishcloth in place over the overflow to seal it well.
Step Five: Bring out the baking soda and vinegar
If plunging doesn’t work, you can try pouring a small amount of baking soda down the plughole, followed by a cup of white vinegar. If this works, you should be able to hear some fizzing as the mixture breaks down the grime. After a few minutes wash the system through with hot water.
Step Six: The U-bend
If you think you’re problem may be coming from deeper within the plumbing, locate the U-bend under the sink. Place the bucket underneath the join to catch any water that leaks out, and unscrew the plastic fitting that joins the U-bend to the pipe. If water starts to come out as you unscrew, let it drain into the bucket before unscrewing further.
Step Seven: Washing the U-bend
Once the U-bend is detached, inspect it and remove any objects that may be causing a blockage. Wash out the bend using soap and water and reattach once it is clean.
If these steps don’t work, it’s time to call a plumber!
