The most common sink to be unblocked is the kitchen sink and this is simply because foodstuffs inadvertently make their way down through the plughole and can gather.
Both the sinks and toilet in your home are attached to what is referred to as the ‘foul water drain’; a drain which as it name might suggest takes waste water and waste products away from the home and into the main sewage system.
The U BendMost commonly blockages in sinks occur in what is known as the ‘U Bend’ – the same name is used to refer to the drainage pipe attached to the rear of your toilet. Given the shape of the ‘U Bend’ and the fact that sometimes larger pieces of debris do not float or can become trapped in the base of this pipe, this is where most of the blockages will occur and this is where you should start.
Blocked SinksThe first thing you will notice when it comes to a blocked sink is that the water may still continue to drain but will take longer to do so. If you notice this problem occur or it is brought to your attention it is best to act sooner rather than later. Likewise blocked sinks will fill with water when there is no plug in the plughole.If you have children in the household it is best to educate them as to what not to put down the plughole. Many DIY enthusiasts have found themselves removing cotton buds, cotton wool, disposable kitchen towels and all manner of other things including – as we have already mentioned – foodstuffs.
PlungingThe first way in which to establish if you have a blockage that cannot be easily removed is to try and plunge the plughole. Plunging is simply a case of removing and adding air to the pipe in order to dislodge anything that might be down there.
With DIY now becoming one of the fasted growing leisure pursuits there are always new gadgets coming onto the market and the latest is what is known as the ‘blast plunger’. This is effectively a pump which covers over the plughole as you might do with your hand or an old fashioned plunger but you force air in and out using a pump handle.
Removing the U BendYou may find that not everything is as easily dislodged as we have described above so you will have to undo the ‘U Bend’. To do this you should have the following items to hand:
- Waterproof Tape
- Plunger (if necessary)
- Towel or cloth
Once you are satisfied that the blockage has been cleared replace the pipe, screwing the threads tightly shut – but not too tightly or they may crack. Use a few strips of waterproof tape to seal around the edges just to ensure there are no excess drips and then plunge the sink again.
After you have completed this procedure you should find the sink is blockage free.
