Of course, even simple plumbing jobs, like clearing a blocked sink, can end up being more complicated than they first seem. We are going to give you some tips on how to unblock a sink in your home. If you have real problems clearing the blockage then it’s a good idea to call a professional plumber to save you wasting any more time.

Why the sink might be blocked in the first place

Before we take a look at how to clear a blockage in a sink let’s take a look at what can cause such a blockage. Understanding this may help you to prevent any further blockages in the future. One of the biggest causes of blockages in kitchen sink drains is the poring of grease and oil down the drain. These substances mix with remains of food that goes down the drain and very easily form a blockage. In the bathroom, hair and skin going down the drain often results in a blockage. If you want to try and avoid a blockage occurring you should:

  • Refrain from pouring oil or grease down the sink.
  • Use a drain guard to prevent items from going down the drain.
  • Brush your hair before you shower to reduce the amount of loose hair that is released when you shower.

It does not take much effort to be careful about what goes down your household drains and doing so helps to protect you against the inconvenience of a blocked sink.

What is the best way of unblocking a sink?

We have talked about ways in which you can try and prevent experiencing a blocked sink in your home, but what if a blockage occurs anyway? The first thing you should do in order to try and deal with the problem of a blocked sink is pour boiling water down the drain. If you have PVC pipes fitted then you should not use boiling water; this can only be done if you have metal pipes fitted in your home. If the blockage remains then you should try using a plunger on the sink. Usually, you will be able to remove a blockage using one of these methods. If this does not happen then it’s worth asking professionals such as plumbingdetectives.com.au for help. They have training and experience which they can put to use helping you to solve your problem.


Hopefully, next time you have a blocked sink in your home, you will be able to solve the problem yourself. If you have problems then it’s worth calling a professional plumber for help rather than spend more time on the task with no guarantee of success in the end.
