Clearing A Blocked Sink

If you think you know the reason why your sink is blocking, you can trys these DIY treatments before calling a plumber.

Boiling water: This is the easiest method to try first. Boil a pot of water and slowly pour it down the drain. Repeat a few times if necessary. The hot water can help to break up any grease or oil buildup that is causing the blockage.
Baking soda and vinegar: Mix 1/3 cup of baking soda with 1/3 cup of vinegar and pour it down the drain. Let it sit for about an hour and then pour hot water down the drain to flush it out. The chemical reaction between the baking soda and vinegar can help to break up the blockage.
Plunger: Use a plunger to create suction and pressure to dislodge the blockage. Make sure to cover the overflow drain (if there is one) with a wet cloth or tape to create a seal.
Drain snake: A drain snake, also known as a plumbing snake or auger, can be used to physically remove the blockage. Insert the snake into the drain and twist it to dislodge the blockage. Pull out the snake and repeat if necessary.

If these don’t work – It is time to call a plumber.

The Blocked Drain Guys have the necessary experience and knowledge to perform drain cleaning and clearing services safely and effectively. We identify any underlying issues that may be causing the blocked sink, such as tree roots, food extracts, broken pipes, or other damage, and provide a solution to prevent future problems.

 Trustindex verifies that the original source of the review is Google. We had a blocked sewer and Craig from The Blocked Drain Guys came out straight away. He was fair, honest, kind, and cleared the problem quickly. Highly recommend them for fast and efficient service – thank you Craig!

For context, before calling Craig we had contacted another company (Dans Plumbing). While they partially cleared the blockage, they then tried to pressure us into unnecessary “repairs” with a ridiculous $17,000 quote, making false claims about damaged pipes. We refused, but still had to pay $1,250 for their overpriced call-out.

In the end, Craig solved the issue properly without the nonsense. If you want genuine service without being ripped off, go with The Blocked Drain Guys.

 Trustindex verifies that the original source of the review is Google. Craig was fantastic to deal with from start to finish. He was incredibly patient, took the time to explain everything clearly (and I had a lot of questions!), and made sure I fully understood what was going on. His work was super thorough, and he managed to clear my blocked drain on the same day—which was such a relief!

On top of that, his pricing was very reasonable, especially for the quality of service provided. I’m so grateful and will definitely be using Craig as my go-to plumber from now on. Highly recommend to anyone looking for a plumber they can trust!

Blocked Sink FAQs

Common questions about blocked sinks answered by Sydney plumbers

Why is my kitchen sink draining slowly?

Slow draining in kitchen sinks is usually caused by a buildup of grease, food scraps, and soap residue in the trap or waste pipe. Over time, these deposits narrow the pipe and restrict water flow. In some cases, the blockage may be further down in your main drainage line, especially if multiple fixtures are affected.

Can I use chemical drain cleaners on a blocked sink?

We don’t recommend chemical drain cleaners. They rarely clear the full blockage, can damage older pipes, and create toxic fumes. If used repeatedly, they can corrode pipe joints and seals, leading to leaks. A plumber with the right tools can clear your sink properly without risking your plumbing system.

What’s the difference between a blocked sink and a blocked drain?

A blocked sink means the blockage is in the trap directly under the sink or in the short waste pipe leading from it. A blocked drain means the blockage is further down in your main drainage system, often affecting multiple fixtures like toilets, showers, or other sinks. If only one sink is slow, it’s usually localised. If everything backs up, it’s a drain issue.

How much does it cost to unblock a sink in Sydney?

We charge from $99 for straightforward sink blockages, with a $0 callout fee. Most kitchen and bathroom sink blockages can be cleared quickly with basic tools or a drain snake. If the blockage is deeper in your drainage system or requires camera inspection, we’ll give you an upfront quote before proceeding.

Why does my bathroom sink smell bad even when it’s not blocked?

Bad smells from bathroom sinks are usually caused by bacteria growing in the overflow drain or a partially dry P-trap. Hair, soap scum, and toothpaste residue create a breeding ground for odour-causing bacteria. Regular cleaning and running water through all drains keeps the trap sealed and prevents sewer gases from entering your home.

Can a blocked sink cause a leak under my cabinet?

Yes. When a sink is severely blocked, water pressure can build up in the waste pipe or trap, forcing water through weak joints or corroded sections. If you notice water pooling under your sink cabinet, turn off the water supply and call a plumber. Ignoring it can lead to cabinet damage, mould growth, and more expensive repairs.
