Blocked Drains

Blocked drains are one of the most common plumbing problems that many residential households encounter and is, therefore, one of the most regular services we carry out.
Blocked bathroom and kitchen drains inside a home are caused by a build-up of hair, soap, food, and general debris, while external drain blockages are caused by soil, leaves and debris build-up and tree roots growing in the drain and blocking the drain.
Some common signs of a blocked drain include foul odours, gurgling sounds, and water that drains slowly.
At Sydney Emergency Plumbing, we all know how frustrating a blocked drain can be, which is why we set out to fix it as quickly as possible.

Our Process for Clearing a Blocked Drain

At Sydney Emergency Plumbing, we follow an efficient and effective process to get your drains cleared as quickly as possible:


Thorough Assessment:

Once we arrive at your home, we carry out a detailed inspection of your blocked drains to identify the cause of the blockage and to assess the severity of the problem.


Customised Solution:

Once we have accessed the situation, we create a solution that addresses the specific needs of your blocked drains. Before we begin any work, we explain the steps that we’re going to take, get a verbal agreement from you and also provide upfront pricing. We ensure that we are transparent in everything we do.


Efficient Resolution:

Our experienced plumbers use the most cutting-edge technology and up-to-date plumbing practices to clear the drain blockage as fast and effectively as possible. We are mindful of our customers and do our best to minimise any disruption to your daily routine. Before too long, your drains are restored to their optimal condition.

How Do We Clear Blocked Drains? (Equipment and Methods Used)

At Sydney Emergency Plumbing, we’re proud to utilise the most cutting-edge equipment and up-to-date plumbing practices to ensure that your blocked drains are fixed in no time.

High-Pressure Water Jetting

This is one of the most common tools used to clear a blocked drain, and for good reason: it is incredibly effective. It involves the use of a specialised nozzle and high-pressure water to dislodge and remove blockages, which leave your drains nice and clean.

RootX Treatment

Also known as the ‘Tree Root Inhibitor’, RootX is a root control solution that consists of foaming sodium liquid. When you mix it with water, it kills roots, prevents regrowth and restores the pipe flow. It is a safe and effective way to kill off any tree roots that are blocking your pipes and drains.

Drain Snaking

A drain auger (also known as a drain or plumbing snake) is a thin, flexible metal cable that is inserted into a blocked drain and moved around until the clog unlodges. It is an easy, affordable and effective way to unblock a drain, no matter the cause.

Electric Eeel Stormwater Treatment

This powerful machine consists of a metal cable with a cutting head attached to the end. We lower this cable into a stormwater drain, and it is rotated and moved around until it is able to reach the blockage and cut through it.

CCTV Drain Inspections

We employ the use of drain cameras to ensure that we get a clear look at the inside of your pipes, work out the cause of the drain blockage and can resolve the issue effectively and efficiently.

Drain Repairs and Relining

If we discover that your pipes are damaged, we can repair them using techniques like drain relining, which is a simple, non-invasive method that strengthens the already exiting pipe with a new lining. This eliminates the need for the pipe to be dug up and replaced, which could result in property damage and is more costly.

How Do You Prevent a Blocked Drain?

Here are some handy tips and tricks to prevent getting a blocked drain:
Dispose of cooking fats and oils correctly:

Instead of washing fats and oils down the drain, pop it into a container and throw it away. Alternatively, you can save the grease and fat to use in future cooking.

Clean your drains regularly:

Use a simple solution of baking soda, and vinegar to clean your drains. First tip boiling water down the drain and then a solution of baking soda and vinegar. Leave it to sit for several minutes and then rinse the drain with more boiling water. Repeat this process every few weeks to ensure that your drains stay clog free.

Only flush the right items down the toilet:

Don’t flush anything besides human waste and toilet paper down the toilet.

Dispose of food waste properly:

Instead of washing large portions of leftover food down the drain, put it in the bin, or feed it to a pet.

Keep the outside clean:

To avoid your stormwater drain from getting blocked, ensure that the area around it is kept clean. Maintain your garden and gutters, and use the hose to ensure that the pipes are kept clean.

Discard of hair in the shower:

If some of your hair falls out in the shower after you wash it, make sure you remove the hair from the shower and drain to avoid a build-up.

Common Signs of a Blocked Drain

These are the most common signs of a blocked drain that we come across:

Foul Odour

This is one of the earliest signs of a blocked drain. Once the debris that is blocking your drain has started to break down, it results in a foul smell that emits from the drains in your home. The longer the drain stays blocked, the more intense this foul odour grows.

Gurgling Sounds

If you hear gurgling or weird noises coming from your pipes, it may mean that the water is struggling to drain away, which is indicative of a blockage.

Slow Draining of Water

Sinks normally drain pretty quickly, so a slow-draining sink is a clear sign that there is something blocking the drain. The longer the drain is blocked, the more debris will build up, and the water will take even longer to drain completely.

Standing Water

If you notice the water pooling at your feet when you take a shower, this means that the water is unable to flow out of the sewer drain effectively.

Toilet Water Levels

If you have a blocked drain, this could result in your toilet water levels being unusual. The water may rise higher than usual when you flush the toilet and then recede to a lower level when it has finished flushing.

Water Backup

If you’re using your bathroom or kitchen sink and you notice that water has risen in another area, such as the toilet, it’s a sign of cross-drainage, which is another telltale sign of a blocked drain.

Low Water Pressure

If you notice that your water pressure is lower than usual, this could be because a blocked drain is causing a limited flow of water to flow through your pipes.

Causes of a Blocked Drain

The following can all cause a blocked drain:

Frequently Asked Questions about Blocked Drains

How to identify if my drains are blocked?

There are certain signs that will surely tell you that you have a blocked drain. These signs are:

  • Water draining slowly
  • Bad odour
  • Gurgling sounds coming from the pipes
  • Overflowing toilets

If your toilet drains are blocked, this is usually a sign of the blockage being located there. This is the same for your kitchen. However, if all your drains are clogged, an emergency plumber should be immediately called as the blockage may occur within your sewer line.

What causes a blocked toilet?

A drain will often become blocked due to obstruction by foreign objects, such as food scraps, jewellery, soap, leaves, plants, tree roots, hair, grease or fat and toiletries. Any of these, and many more items, can easily create a block inside your drain. Also, the age and condition of the pipes can be a significant contributor to causing a blockage. The most common items causing blocked toilets across Sydney, according to a survey in 2021, are:

  • Baby wipes
  • Cotton pads
  • Sanitary products
  • Baby wipes
  • Toys

Why is my bath or shower draining so slowly?

If you observe the water in your bathroom or kitchen draining very slowly, it indicates a blockage in your drain. Slow shower or bathroom drains are often caused by a slimy build-up of everything that runs down the shower drain:

  • Soap & Shampoo
  • Dirt & Debris
  • Dead Skin Cells
  • Hair

Usually, homeowners do not have the knowledge or equipment to solve these plumbing problems. Therefore, it is better to call your plumber to handle your slow-draining shower.

Why are my drains making a gurgling sound?

Gurgling sound is caused when something is preventing water or air from flowing through your drains. As the water slowly travels through your drains, air bubbles begin to form and create a gurgling sound. Whether it’s your sink, toilet or shower, even floor drains all can make that gurgling sound. The possible causes are:

  • Blocked Drain Line
  • Partially Blocked Drain
  • Completely Blocked Drain
  • Clogged Vent System
  • Damaged P-Trap
  • Issue In The Main Sewer Line

Why do my drains smell so bad?

If a foul odour emanates from one of your sink or shower drains, something is likely wrong, and in many cases, it indicates a problem with drainage. They are often the result of one of the following:

  • A sewer gas trap problem: A sewer gas trap or P-Trap is a part of the drain where the water is stored. Its purpose is to block gases from entering the pipe and into your home. If water is not moving correctly in the P-trap, usually due to leakage, the gases can enter through the pipe and into your home.
  • An organic build-up: These organic residues accumulate over time in the P-trap or the pipes. The most common elements that result in partial pipe blockages causing smelly drains are:
    • Hair
    • Toothpaste
    • Soap
    • Grease
    • Food waste
  • Sewer line problems: If you’ve noticed a foul odour from multiple sinks, this may indicate a broken or blocked sewer line.

How do you prevent smelly drains?

Prevention is always better than trying to find a solution. Doing some simple maintenance can prevent smelly drains from becoming a problem. Here are some easy ways to keep your drains smelling fresh and clean:

  • Boiling water: Tip boiling water down the drains in your house about once a week.
  • Baking soda, vinegar & boiling water mixture: Once a month, do the baking soda, vinegar, and boiling water method.
  • Clean your garbage disposal: If you have a garbage disposal, regularly put ice cubes into it which will get rid of any excess grease and will give the blades a good scrub. Also cut up a lemon or orange into small wedges and put it into the garbage disposal – this leaves it smelling fresh.
  • No fats & oils: Avoid putting oils and fats down your sink.
  • No food scraps: If you don’t have a garbage disposal, make sure all food scraps go into the bin or get fed to pets instead of going down the drain.
  • Strong drain cleaners: Use strong, commercial drain cleaners if nothing else works.
  • Maintain regular tap use: Make sure you regularly turn on the taps in your rarely used bathrooms. This ensures that there’s no build-up of grime and prevents your P-trap from becoming empty and releasing sewer gases into the house.

Should I be cleaning my drains regularly to prevent blockages?

Cleaning your drains regularly can be your best bet to preventing any blockages and clogs. A significant blockage always starts off relatively small. Many individuals do not think about their drains until they have a problem. They usually put drain maintenance on the back burner. But, the best way to avoid drain clogs is to have your drains cleaned regularly.

Can tree roots block my pipes, and how can I stop them?

Trees should be planted at least 3 metres away from the sewer pipes to avoid root intrusion. If this is not possible and you still want to plant trees on the property, it is best to choose slower-growing trees with non-aggressive root systems. However, if trees are already a part of the property, they will most likely cause issues to the pipes.

Again, regular cleaning is the best solution to ensure your pipes are always clear. If roots have penetrated your drain, you will need to hire a professional plumber with experience in root cutting technologies. Unfortunately, tree roots are invisible enemies to your plumbing health. While DIY remedies like applying rock salt and copper sulphate are great temporary solutions, sometimes expert professional root removal and pipe replacement are only the best course of action.

How can I lower the chances of a blocked drain?

The important thing is to remember that every time you use your sinks, ensure you do not leave food scraps or other residues as they will block your drains. To avoid drain blockage regularly, it is vital to ensure that any inherent issues with the plumbing network are repaired.

Engage a plumber regularly to inspect that all drains are performing correctly. They always have the right tools and know-how to isolate the issue and apply the proper techniques to keep drains clear from foreign deposits. Staying informed and prepared can help you avoid all the unpleasant experiences that arise from blocked drains.
