How to Unblock a Kitchen Sink

Having problems with a blocked sink in your kitchen? Sink blockages have many causes, and they prevent water from correctly emptying from the sink in your kitchen. Although not all drainage issues can be fixed by DIY, there are luckily some simple initial steps that you can take to try and diagnose and fix the issue before calling in the professionals.

Before starting to diagnose your problem, you will need to gather a couple of items to help you.

  • Plunger
  • Towels
  • Bucket

Note – If your sink features an integrated waste disposal unit, make sure you turn this off!

Step 1 – Boiling Water

If water is not draining properly, rather than being completely blocked and not draining at all, start by pouring boiling water down the plug. This can help dissolve or break up any built up cooking fat or food that could be causing a blockage.

TOP TIP: Be careful with using powerful drain unblockers and chemicals. They can have health risks if misused and can even be corrosive to rubber seals within the pipework.

Step 2 – Plunging

If you find that your sink is completely blocked or hardly draining at all, it is time to try plunging it. Place the plunger over the plug hole of the blocked sink, and remember to block off the overflow hole in the sink with a kitchen towel as this will allow for the air pressure to build up and push the blockage downwards. Plunge up and down for around 20 seconds.

After this initial 20 seconds, remove the plunger. Hopefully, the water in the sink will begin to drain. If not, try again but this time for a longer period of time. If this doesn’t work, move on to the next step as plunging too much or too vigorously could cause damage to any fragile pipework.

TOP TIP: It’s important that when you put the plunger into the water, you do so at an angle and roll it in. This is so you plunge water, and not air, into the drain.

Step 3 – Clean the Trap Pipe 

If plunging doesn’t do the trick, the next step is to disassemble and wash out the trap pipe, the ‘U’ shaped pipe that comes out underneath your sink. Sometimes food waste can get caught in this and prevent water from draining correctly. Giving the trap a good wash out and removing any debris should do the job if this is the issue.

Once you’ve cleaned it out, replace the trap, and test the sink again. We recommend calling a professional if you are not confident in doing any part of this step.

TOP TIP: Unless you want dirty water flooding your kitchen, place a bucket underneath the downpipe coming directly out of your sink. Any water in the sink will then be caught in the bucket, and not by your kitchen floor or cupboards!

Step 4 – Call in a Pro

If your sink still isn’t draining properly, the next step involves using further methods and tools such as ‘snakes’ and water hoovers to try and clear any more possible blockages. At this point that we would recommend calling in a professional.

How to Stop Your Kitchen Sink Getting Blocked

Prevention beats fixing every time! 

In an ideal world, you will never experience something as inconvenient as a blocked drain. However, there are a number of simple measures that you can take to prevent drains from becoming blocked in the first place.

Food – One of the main culprits of blocked drains is food. Items like coffee grounds and starchy food such as rice and pasta can be a nightmare for drains, so dispose of these foods using your food waste bin (or your general rubbish bin if you don’t have one).

Oil – Cooking oil is the arch-enemy of drains. You should never dispose of cooking oil down the sink. Instead, you should store your old cooking oil in a suitable container, and then dispose of it with your general rubbish.

Hot Water – By running hot water down through your drain after each use, you help to prevent the buildup debris which may cause blockages.

Plug Guard – Help ensure that food and potentially problematic items don’t go into your drains by using a plug hole guard.
