Are You Dealing with Any of These Common Causes of Blocked Drains?

Blocked drains are often caused by a few repeat offenders. Identifying the source early can prevent bigger problems later.

Grease and Fat Build-Up: Kitchen sinks often clog from grease, oils, and fats being washed down the drain. Over time, these substances harden and block water flow.

Hair Accumulation: Bathroom drains frequently get clogged due to hair collecting and binding with soap scum, leading to slow or stopped water drainage.

Foreign Objects: Wet wipes, sanitary products, and even children’s toys can end up in toilets or drains, creating stubborn blockages.

Tree Root Infiltration: Roots from nearby trees can penetrate cracked or aging pipes, growing inside and causing major drainage issues.

Broken or Collapsed Pipes: Old or damaged pipes can collapse or crack, interrupting the flow and causing water to back up.

Incorrect Pipe Installation: Poor workmanship or DIY plumbing jobs may lead to misaligned or poorly graded pipes, which can cause frequent blockages.

How We Clear Blocked Drains Across Sydney

Our approach to clearing blocked drains combines accurate diagnosis with specialised equipment, allowing us to fix problems quickly and prevent them from recurring. Each job is assessed individually, so the right method is used for the type and severity of blockage.

Blocked Drain Assessment: We begin with a detailed inspection of your drainage system to identify where the blockage is located and what’s causing it. This step avoids guesswork and ensures the most effective repair method is chosen from the start.

High-Pressure Water Jetting: For stubborn blockages, we use high‑pressure water jetting technology. This equipment cuts through grease build‑up, food debris, and even small tree roots, flushing them completely out of the pipe rather than just moving them further along.

CCTV Drain Camera Inspection: When the blockage isn’t immediately visible, a CCTV camera inspection provides a live view inside your pipes. This helps us confirm the cause—such as cracks, collapsed sections, or foreign objects—without digging up your property.

Tree Root Removal and Prevention: Tree roots are a leading cause of blocked drains in many Sydney suburbs. We remove intruding roots from the pipe and can recommend preventative treatments or repairs, such as pipe relining, to stop them from returning.

Drain and Fault Location Services: If the problem is structural, we use advanced location tools to find the exact point of damage. This allows for targeted repairs, reducing disruption and cost compared to traditional excavation methods.

Emergency Plumbing




A plumbing emergency occurs when the drain system of your house is damaged to the extent that it can lead to severe consequences. For example, damaged pipes can let harmful gases enter your home. It is a huge health hazard if you or your kids inhale in such an atmosphere.

You should also treat blocked drains as a plumbing emergency. The dirty water can flow back into the sink and make you and your family members sick. This water is highly contaminated with bacteria, moulds, and other disease-causing microorganisms.

Also, the accumulation of contaminated water inside your house can damage your house’s flooring and property. It could lead to steel corrosion, wood swelling, and delamination of the luxury flooring and walls. Hence, you should treat blocked drains as soon as possible.

Even gas leaks are a dangerous sign of plumbing issues. Delaying it can put the safety of your loved ones at risk. It can cause fire to erupt or natural gas poisoning upon inhalation. You should not wait longer to call a professional plumbing service to resolve this issue.





We aim to give our current high-quality services. For this purpose, we provide the fastest answer. Once you call our landline number, the staff will be there in some minutes to cater for your plumbing needs.

If you give us a call, consider that your work is already done. We value your time; that’s why we prefer the fastest arrival of our expert plumbers to your specified location.

The quick arrival facility protects you from any mishap during an emergency plumbing situation. Our plumbers can arrive at your house in a few minutes and can fix the issue very quickly.

A plumbing situation can be susceptible in some cases. If plumbers didn’t arrive on time, anything could happen. We ensure your safety and security by offering the fastest arrival facility to keep you secure from emergencies.





As soon as you realize a plumbing emergency has occurred, you should call a professional plumbing company to visit and sort the issue out. However, till then, you can do a few things to reduce the damage it can cause.

Immediately shut off the main valve of the water supply in your house. You can find it outdoors near the water meter. Although it wouldn’t resolve the issue, your home will at least stay safe from flooding and water damage.

You can also try to unblock the drain through a plunger. Moving the plunger back and forth at the blocked drain’s opening can eliminate soft blockages. However, it wouldn’t stop the stubborn block, and a plumber could only help.

Moreover, you should never use chemicals to clear the drain as it could corrode the pipes and damage them, which leads to a plumbing emergency. It’s also important to explain the issue on call so the company can send an experienced technician.

Also, you shouldn’t wait upon noticing a minor symptom of a plumbing emergency. You are making a mistake if you think it will sort out on its own. The intensity of a plumbing issue will only increase with time, turning into an emergency.





Although having no water in the house is not a plumbing emergency, it’s one of the worst issues you could face. Many things can cause this problem. However, you must check a few elements before calling a plumbing service to know if the issue is significant or if you can sort it out at home.

Check any other tap in your house to see if they’re working fine. If yes, then the tap is causing a nuisance. It’s a minor issue that you can sort out yourself. However, you should call a plumber to look into the problem if there’s no water in any tap.

A blocked tap connection is one of the most common reasons for the no-water problem. Sediments can deposit inside the connection over time and make it subjected to rust damaging the pipe. Similarly, poor-quality water lines or improper drain installation can cause this issue.

Both issues are considered to lower the water pressure leading to a lack of water in taps and showers. It can also occur if your house’s pipes are damaged or rusted. A buildup of grime inside the line can interfere with the flowing rate of water.

Blocked Drains




You could be facing frequent drainage issues due to multiple reasons. The primary being a buildup of excessive debris in the drainage pipes. It includes soap scum, hair, food particles, or grease.

If the drainage issue occurs in your yard, it could be due to leaves getting accumulated in the drain. Even clumps of dirt can block the drain. It can also happen if the pipe is broken, as tree roots can enter the drain system and block it.

Overall, a poor drainage system is a culprit behind the recurring overflowing of gutters. It can happen if your house’s plumbing system isn’t robust. The pipes can crack over time, leading to persistent drainage issues.

Even corrosion or ageing of the lines can contribute to this problem. If there are open joints in the pipe, water can leak, causing it to flow inside your house. If unblocking the lines doesn’t help, it’s most likely time to replace them.

Our professional plumbers use a high-resolution camera cable to detect cracks in pipes. It helps decide whether you need to replace them or repair them would be enough.





There are several home remedies to unblock small drains. You can use a solution of baking soda and vinegar, a wire coat hanger and dish detergent.

To apply the baking soda and vinegar to the drain, clean the drain with hot water. Mix a cup of baking soda and vinegar with hot water and pour the solution into the drain’s opening. Clean it after some hours and see whether it worked or not.

The wire coat hanger is another effective remedy to unblock small drains. First, straighten the hanger and leave the hook end. Now hang the hook end in the gutter to pull out any substance blocking the drain. After removing the hanger, wash the drain with hot water.

Dish detergent is a home remedy that is only effective for the toilet or shower drains. Hair can easily block your toilet and shower drains, resulting in a black residue. Dish detergents can break the residue and clean your drains.

Pour a cup of detergent followed by boiling water on the drain. After some time, remove it using your hands, and don’t forget to wear gloves.

These home remedies can’t remove large drains, so chemicals are better.





As anyone who has ever dealt with a clogged drain knows, it can be a nuisance. Water backs up in the sink, making it difficult to wash dishes or even get a drink of water.

You may consider a blocked drain a minor problem, but it isn’t. If you leave a drain blocked, you can face serious consequences. The consequences include leakage, bad smells, and flood /wall damage.

Not treating a blocked drain for longer periods can cause a high-pressure build-up in the pipe. Thus, resulting in serious issues such as moulds, damps and rots.

The waste passing through the drain can produce a bad and irritating smell. A blocked drain affects the pipes of the drainage system resulting in the formation of fungus and other harmful bacteria. As a result, these bacteria’s produce frustrating smells.

Since blocked drains can build up the high water pressure, they try to direct force to the other side of the pipe. The other side can break at any moment. If the pipe is externally connected to your house, it can cause water flooding.

A blocked drain’s most severe and dangerous effect is that it can damage property or walls. It can cause cracks and leaks in the walls. As the water enters the space, it expands and then finally cracks. This can result in weakness or even breakage of the walls. Such damages are severe and can cost several hundred dollars to fix.

In order to avoid these problems, it is important to clear blocked drains as soon as possible. There are several things that can be done to unclog a drain, including using a plunger or snakes. However, if the problem persists, it is best to call a professional plumber. Taking care of a blocked drain may not be fun, but it is certainly better than dealing with the consequences of leaving it unchecked.





The insurance policy may not cover some blocked drain expenses. The expenses include drain blockage cleaning, repairing, replacing and other drain maintenance costs. You are responsible for the maintenance of drains, and not your insurance company.

However, most home insurance policies cover the expenses of structural damages like cracks and leakage if they occur due to water damage. It also covers the costs of after-effects due to blockage in gutters.

If your insurance policy covers all these expenses, then you are on the safe side. All these cases apply when it’s an accidental blockage in drains. You cannot claim insurance for damages if the backup is caused due to poor maintenance.
