Tree Roots are a MAJOR Reason Drains Block Up!

When landscaping or gardening it is important to find out where your sewer and stormwater drains are laid. Some plants can grow with deep, strong roots may go through small cracks and spaces in your pipes and potentially cause massive damages to them. Through our years of experience, tree roots in drain is usually the issue 75% of the time.

Oils and Water Simply DO NOT Mix!

Do not pour oils down your kitchen sink. We advise our clients to pour it into a jar and prevent fats and oils going down your drains. The most common cause of kitchen sink blockages are a result of people pouring oil and waste scraps down their drains.

Oils and Water


DO NOT Flush Female Hygiene Products & Baby Wipes down the Drain!

Dispose of these into a rubbish bin and please note regardless of their claims all wipes cause blockages, see article below:

Femaile Hygiene Products & Baby Wipes

Collect All Hair After Showering

Collect all hair after shower use or use a hair catcher on a drain to ensure hair does not enter drains and cause them to block


Protective Gutter Guard

Ensure leaves and debris are kept away from all stormwater lines. Placing protective material like gutter guard or having mesh over your stormwater drains is a great way of ensuring no debris enter the lines

Protective Gutter Guard

Rootx Application

If your drains have a history of roots, a Rootx application every 12 months is highly recommended. Below are some of the results we have had on our jobs


Tough on Roots, Easy on Pipes

RootX kills roots using aquatic herbicide Dichlobenil, a non-caustic, non-fumigating and non-systemic solution that will not harm pipes, septic systems or above-ground vegetation. Effective for 10 years running and trusted by plumbers nationwide.

Grease Blockages Drain

Commercial Grease Blockages

Grease blockages Sydney occur mainly in commercial kitchens or kitchen house lines as fat is poured down the drain. You have probably heard the old expression “oil and water, simply don’t mix. What ends up happening is the fat will eventually find its way into the bottom of a gully or a sewer line and will eventually block the line. ALL oil MUST be placed into a jar or into a bin and disposed of safely. Pouring fats and oils down your lines will only mean, a blockage is bound to occur.

Preventive Maintenance Plans

In commercial sinks and kitchens, it's almost impossible to try and prevent oil build up within drain lines. We regularly place preventive maintenance plans in place every 3 months at several commercial kitchens and restaurants and use a product called “Grease Release” to help break down the fat in the lines and ensure all blockages are eliminated. Not having a regular maintenance plan in place could cost the restaurant or kitchen thousands of dollars in downtime if their drains were to ever block during trading hours. Imagine the loss of revenue each time a drain was blocked.

Here’s a Quick Video on How it Works:

Jet Blaster

Jet Blaster Sydney

Drain Jet Blasting Sydney

A jet blaster put simply is a petrol operated machine which use water (similar to a fire truck) to run water through hoses at pressure in excess of 5000psi to help clear the following issues. These machines are the most effective, cost efficient way of clearing a sewer or stormwater blockage in Sydney.

Most Common uses for Jet Blasters


Blocked drains caused by tree roots


Grease line build up


Clearing silt, debris & excessive rubble from drains


Cleaning or hosing down of driveways

Attachments to suit different sized blocked drains

A big advantage of having a jet blaster is the fact we have different nozzles for different applications. For example, if we had large tree roots in the line, we could use root cutting nozzles to help eliminate the roots. If we had a large grease build up, we could also use a grease head which targets the breakdown of grease whilst in use.

There are also attachments and hoses to target the smaller sized drains which makes this machine a great tool in tackling the most stubborn of all blockages. The below photo is a number of the many nozzles each one of our drain specialists has in his vehicle, ready to tackle any blockage which you may have.

The Difference between a Jet blaster & an Eel

Traditional Eel Drain Cleaner

Traditional Eel Drain Cleaner

An eel was a machine used in the early 1990s and 2000’s and was the main method of cleaning drains as no other options were available.

They were heavy, extremely hard to use, worked sometimes and extremely high in maintenance. They damaged pipes and could not get around bends like a jet blaster essentially making them extremely hard to use on all applications.

New & Improved Jet Blaster

New & Improved Jet Blaster

Fast forward and the benefits of a jet blaster over an eel are endless.
The fact that is its mobile and you can move it anywhere which is needed. A jet blaster can have up to 80m of hose compared to the heavy short attachments of an eel. The efficiency of a jet blaster running at 5000Psi each time compared to an eel which may break down due to the amount of attachments having been placed onto each end. The single most important thing over above all, is a jet blaster will leave your pipes in much better condition and never damage them. An eel nearly 90% of the time damaged all affected sewer lines.

Plumpton blocked drain sewer repair

Reported Problem - Attended a blocked sewer drain in Plumpton with reports of an overflowing sewer drain in the backyard. Conducted a high pressure jet blast and CCTV camera inspection and found multiple issues throughout the line. We provided the customer with a permanent drainage solution in Sydney to help repair the issue permanently.

Works completed to resolve the problem- Access for an excavator into this property was not possible due to the house layout meaning the line at a depth of 1.7m needed to be dug out by hand. Our technicians rolled up their sleeves and dug down to the defective earthenware line which had collapsed.

We dug the line out the defective line and replaced the defective section of pipework with new PVC pipework. We raised an inspection to ground level for any future access which may be needed.

On completion of the works the area was backfilled and site was cleaned.

Blocked Drain FAQs

When you are unblocking and outside drain, the very first step is to assess what is causing the blockage. You can open up the drain cover- use a gloved hand to check whether there is a blockage right under that area. If the blockage is a deeper, you would have to use an auger or drain snake. In case of a very severe obstruction deep inside the pipe, a water pressure jet would be needed. If this does not solve the problem and tree roots or other stubborn debris are causing the blockage, you would need to hire a licensed plumber for clearing the drain.

When you have a drain blockage, if your plumber tells you that the blockage exists on the street and not on your property, it would be the Water Corporation's responsibility to deal with it. Once the plumber has inspected the sewage system and determined that the blockage truly lies outside your lot's boundary, they will call the water corporation and tell them that the blockage exists. The latter will then pay the plumber a specific standard fee for identifying where the blockage is.

It is the landlord's responsibility to ensure that all the plumbing systems on the property are in good condition at all times; this includes the drainage system. So it is their responsibility to clear a blocked drain if the blockage has occurred due to an ongoing problem. However, if it is determined that the blockage is the tenant's fault, it would become the tenant's responsibility. In case of an emergency, the tenant would need to inform the landlord about the blockage. They can get the work done by a professional, and then ask the landlord to reimburse them.

The average cost to hire a plumber for unclogging a simple bathroom tub or kitchen sink is in the range of $80 – $120. However, if the work is more complex, this cost can increase to $300 – $500. Unclogging a laundry drain will cost anywhere between $150 and $270. There could be a price variation for unclogging drains, depending on the market and the severity of the clog. Some plumbers would charge a fixed rate while others would charge an hourly rate, and there may also be a call-out fee involved.

Home insurance generally covers the costs of any unexpected damages. It means that if there is any gradual damage to the plumbing fixtures such as the drain pipes, it would not be covered. It's because these problems are avoidable with regular maintenance. If damage has occurred due to a heavy impact or the drains are blocked due to collapse, the insurance company may assess this damage. They may cover it as part of your home insurance policy. However, this is something you would need to check with your insurance provider.

Stormwater pipes are under the ground; locating them visually is not possible. If you want to find a stormwater pipe, look for grates or pits in that space. Work out the overall natural fall of the areas. In most instances, stormwater pipes are installed to work naturally with the surrounding ground, and you will be able to detect where they are draining to. However, if you find it challenging to locate these pipes, you can always call in a licensed plumber. They will also help you with this detailed inspection and the information.

There are various ways in which a collapsed sewer line can be fixed. One of the most advanced methods of fixing this problem is to opt for relining in which an epoxy sleeve is inserted into it, and inflated to form a pipe within the pipe. The traditional method involves excavating the area and replacing the collapsed section of the pipe with a new one. Rerouting the collapsed sewer line is another solution, but it might not work in all settings. A professional plumber will be able to tell you which option would work best for your situation and type of pipe.

Sewer line repairs may not always be covered under home insurance. However, this would depend on what has caused the damage. For example, if the system has suffered some damage due to a lack of maintenance, it would not be covered. On the other hand, if the damage has occurred due to a massive impact or some natural calamity etc. the insurance company might cover it. Since every company has a different policy, you would have to check the details of your specific insurance coverage with your provider to understand whether swear line repairs are covered in it.

If you have a smelly drain, there are some simple ways to get rid of the odours. A mixture of baking soda and vinegar does wonders. First run some hot water into the drain, pour in a cup full of baking soda and follow it up with two cups of vinegar. Allow this to fizz for some time and leave it untouched for at least an hour. After that, you can flush your drain with some hot water from the tap. This is one of the simplest and most effective ways of clearing smelly and clogged drains. However, if this does not work, you would have to call in a licensed plumber to address the issue.

If you find a noxious odour emanating from the drains in your house, it could be sewer gas escaping from the system. While this smell can be truly unbearable, it also contains bacteria and methane, which can be dangerous to the health of you and your family. It can result in headaches and various other serious ailments and affects the hygiene levels on your property. A smelly drain indicates a problem in the drainage system, and you need to get it fixed without delay. Call in a licensed plumber to attend to the problem.

No, blocked drains are generally not covered by insurance.

In our experience a number of articles posted online claim that boiling hot water and bi carb soda can help clear blocked drains. This statement is completely false, in fact adding bi carb soda can make the issues worse. Refer to our DIY videos for more information on how to clear drains
