Here at MIlbur Plumbing, we understand how frustrating a repeatedly blocked sink can be. Not only is waiting for a sink to slowly drain frustrating but the odour and noise of a malfunctioning drainage system can turn an annoyance into a serious cause of stress within your home.

While plungers and over-the-counter powders can help, often blocked drains are caused by deeper underlying issues such as tree roots and non-degradable blockages that need professional services to resolve. It’s important then to get a professional diagnosis of your sink blockage to prevent further damage to your property.

Tips to Unblock a Sink

Traditional remedies for a blocked sink will have you digging through the kitchen cupboard for the long-forgotten rubber plunger and pouring baking soda down the plug hole. While these solutions can sometimes help with minor blockages, the truth is they are largely ineffective and often neglect to address the cause of the blockage.

Milbur Plumbing uses the following professional sink unblocking techniques to make sure the problem is truly resolved:

High-pressure Water Jetting

Often, toilet blockages are nothing more than too much toilet paper being flushed at once. These clogs typically resolve themselves after a short time but in the meantime you can run the risk of overflow, damaging your bathroom floor and potentially creating an unsanitary environment.

Chemical Drain Cleaners

In some cases, Milbur Plumbing technicians may also employ the help of chemical drain cleaners in addition to high-pressure water jetting. These industrial-strength chemical agents are not available to the general public and are useful in the case of hair, food scraps, soap and scum buildup.


Another technique Milbur Plumbing employs that can also be used at home yourself is cabling, also known as a drain snake. This coil of wire has a brushed end that is gradually inserted into the drain of a sink and then rotated to dislodge any blockage.

We Provide Unblocking Services for Many Types of Drains Including:

Toilets: Unclogging a toilet is not pleasant and runs the risk of causing unhygienic overflow if left improperly treated.

Sinks: We can service the kitchen, bathroom, vanity, and all other types of sinks in your home. We also offer unblocking services for commercial and public sinks.

Showers: Most commonly blocked by a buildup of hair, Milbur Plumbing can treat showers, cubicles, and wetroom blockages.

Bathtubs: Sometimes featuring multiple drainage holes, identifying the cause of a blockage in a bathtub can be difficult. With Milbur plumbing’s CCTV inspection devices, we can easily diagnose the problem.

Grease traps: A particularly messy job if unprepared, declogging a grease trap is best left to professionals who will ensure no grease re-enters your system.

Floor drains: Built-in floor drains are one of the most commonly blocked drains with debris entering the drain regularly. With the drainage system underground, it is also one of the more difficult blockages to fix without professional help.

Stormwater drains: Keeping your stormwater drain blockage-free is vital to protecting your property from water damage. At MIlbur Plumbing, we not only recommend calling us to resolve any problems you are having with your storm drain but also to book a maintenance visit if yours has never been checked.

We Provide Emergency Unblocking Services in Sydney

Even the most careful homeowners will, at some point, encounter a blocked sink or drain. While these are often minor and are easily resolved yourself, there are also times when blockages pose something of an emergency.

By using Milbur Plumbing, however, you place your home’s plumbing in the safest hands possible, with a workmanship guarantee giving you peace of mind that your sink will be unblocked correctly.

How Does a Sink Become Blocked?

In our experience, we typically find three main causes of sink blockage. These are:

dirty sink

Grease, oil, and fat: While these are often liquid when poured down the drain, upon hitting the water in the pipework these congeal and solidify. Not only does a build-up of this fat and grease cause a blockage in itself, but also catches other debris compounding the issue.

Food scraps: Often, those little bits of food left on the plate after dinner get washed away down the sink. While these are often washed away, it’s good practice to ensure all scraps are scraped off plates prior to washing and to use a plug “catcher” to prevent blockages. It’s also important to not wash smaller scraps such as coffee grounds down the sink as these can also cause blockages.

Soap and hair: Typically affecting bathroom sinks, soap and hair can often form significant blockages in your pipework. Long hair especially is prone to causing blockages tangling with other hair and soap in the drain. A drain hair catcher is therefore recommended.

Unblocking a Sink Can be a Challenging Task

Fixing a blocked sink is not easy. While a plunger can help drain away accumulated water by disrupting a blockage, resolving the problem completely is almost impossible without the right tools. By the time Milbur Plumbing technicians are called out to resolve a blockage, customers have tried a host of DIY solutions. In most cases, customers can save money, time, and hassle by simply employing the professional help of Milbur Plumbin as soon as you encounter a blocked sink.

Milbur Plumbing should be your first port of call when you encounter a blocked sink. Not only will we get to your property promptly and resolve the problem, but we can provide expert advice on avoiding the problem in the future.
A blocked sink if left untreated can often lead to much larger problems. One major issue that can occur is a build-up of pressure that leads to cracks and leaks in pipework elsewhere on your property. So, while the blockage may be in your kitchen, for example, left unresolved a blocked sink can be a property-wide problem.
It is possible to unblock your own sink using DIY treatments such as plungers, baking soda, and drain snakes. These can often help get water to begin draining away. However, these treatments rarely fully resolve a problem. In the case of grease and fat, for example, the build-up will remain and will soon reappear. Therefore, it is important to seek professional advice as soon as possible.
Home and contents insurance policies differ between companies, meaning you will need to check your own policy to see if it covers damage caused by blocked sinks. Nevertheless, most policies do not cover the cost of repairing a blocked sink itself.
Outside drain blockages can sometimes cause blocked sink-like symptoms if severe enough. If you discover a blocked outside drain, get in touch with Milbur Plumbing and we can help fix the problem promptly.
Blocked sinks are typically more of an annoyance than an emergency. However, in some cases, access to a functioning sink can be considered an emergency. In some environments, a sink serves as part of emergency facilities such as face and eye washing stations in factories.
Typically, commercial drainage systems are a lot more complex than residential ones. In almost all cases, a blockage in a commercial system will require professional services.
Tree roots growing through a drainage system are a big problem and can cause slow draining in your sinks as well as gurgling sounds. While plungers and baking soda will do nothing to resolve this, Milbur Plumbing can use CCTV inspection to discover the offending roots and use high-pressure water-cutting tools to remove the roots from your plumbing.
