Ask a plumber what the most common call-out is for, and most will answer almost instantly: a run-of-the-mill sink blockage. And when you stop to think about it, it’s really no surprise. You use that kitchen sink every day and quite often push those vegetable peels and other food scraps down the drain, don’t you? And in the bathroom, stray hairs mix with soap, flakes of skin, wads of toothpaste and other gunk and gradually become a hopelessly blocked sink.

  • Sink slow to drain?
  • Hearing gurgling noises?
  • Smelling foul drain smells?

Oh no, your sink is blocked – or it’s well on the way to getting there! Luckily, the local Sydney plumbing market is so competitive that professional help is only ever around the corner. They’ll use all of their most proven techniques, years of on-the-job experience, state-of-the-art diagnostic equipment like CCTV drain cameras and powerful blockage-blasting tools like ultra-high pressure water jetters to get your drains flowing again soon.

But are there a range of pretty effective do-it-yourself methods on how to unblock a sink drain that you can try for yourself before paid help arrives? Yep! If you notice your sink is blocked, follow this easy step-by-step at-home process for putting it right without needing to call a blocked drain plumber:

1. Start with the plughole

Screw it out or otherwise remove the plughole and check for gunk, grime, scum and sink debris.

2. Move on to the plunger

If the plughole is covered with water, that’s great – because the airtight seal for your trusty home plunger will be ideal for what comes next. Use a rag or cloth to also block the overflow and then create a complete seal with the working end of the plunger.

Now it’s just a matter of ‘plunging’ the blocked sink with an up and down motion as vigorously as you can handle.

3. Try baking soda + vinegar

How did you go with the plunger? If you got no joy, don’t despair – because the next DIY ‘how to unblock a sink drain’ fix may well do the trick.

Head into the pantry and pull out your baking soda and white vinegar – and if you don’t have any, add them to the shopping list. Don’t worry too much about the quantities – just pour some of the baking soda down the drain first and wash it down with a cup or so of vinegar.

Let it all fizz for a few minutes – up to half an hour – and then follow up the brew with a full kettle of almost-boiling water.

4. How’s the U-bend?

If you’re feeling particularly handy and adventurous and the three steps outlined above didn’t work, you could always check the U-bend for a blockage. That’s because the shape itself makes the bend particularly susceptible to a build-up of gunk.
