Tips on unblocking your drain

Post May,2019

We have all faced the situation where the drain in your kitchen sink, toilet basin or shower drains water away at a snail’s pace.

Some more stubborn blockages will prevent all water from emptying.

Fear not, we have shared some tips below to help you unblock your drain.

Boiling Water

Being one of the fastest and easiest ways to unblock a drain, pouring boiling hot water down a drain is something that is accessible to all.

It may take a couple of full kettle loads being dispensed down the drain to dislodge the blockage but pouring slowly and giving it a couple of seconds between each full kettle spill should prove to be beneficial.


A tried and tested method that requires some elbow grease.

Persistence is the key, but it can be very tiring, try and be patient however as this method tends to be successful.

Baking Soda and Vinegar

Long considered as two of the best natural cleaners available, the combination of Baking Soda and Vinegar is regarded as a highly effective solution.

A mixture of 1:1 ratio will give you a fizzy solution that can be poured straight down the plug hole.

For the mixture to have maximum impact, it is best to leave the sink untouched overnight, flushing through with hot water in the morning. 

If you are pressed for time, an hour’s worth of soaking will provide an impact on that stubborn blockage.

Salt and Baking Soda

Another one of our natural remedies on this list of tips is the combination of Salt and Baking Soda, which proves to be a powerful cleaner.

Again, mixing at ratio of 1:1, a strong chemical reaction is caused when poured down the sinkhole and then left to work its magic.

Only add boiling water after 20 minutes and that’s all, the blockage will disappear!

Chemical cleaners

All supermarkets and good DIY stores will sell drain cleaners.

Always follow the instructions that come with a chemical cleaner and they offer additional unblocking power to the other solutions provided in this blog.

Biological Cleaners

For those who are more environmentally minded and dislike the use of anything chemical related, biological cleaners are a more acceptable option in cleaning that stubborn blockage within your drain.

Although not as powerful as a chemical cleaner, biological cleaners are effective against blockages composed of soap and hair.

Cleaning the U bend

Probably the more complex of all the remedies mentioned, opening the U bend under your sink does not appeal to all.

The pipe under your sink should have a U-shaped pipe where you can unscrew the nuts on either side with the use of some tools, namely a wrench.

Ensure that you have a bucket under the pipe to catch any leaking water and parts of the blockage that may fall out when you are opening the nuts.

Empty all the contents of the pipe into the bucket, and the use of bottle cleaner will be handy in rummaging around all corners of the pipe to remove all the blockage.

Once cleaned, piece back the pipe and the blockage should be gone!
