Common Causes of a Blocked Sewer

Tree Root Intrusion

Tree roots are a leading cause of blocked sewers. They seek moisture and can break into sewer pipes, creating dense root balls that trap waste and cause severe blockages and pipe damage.

Collapsed or Damaged Pipes

Older pipelines can crack, misalign, or collapse due to ground movement or age. This obstructs the entire sewer line and requires immediate, expert attention to prevent major sewage backups.

Grease and Solid Buildup

Pouring fats, grease, and oils down the drain causes them to solidify in the sewer line. This creates large, sticky blockages that trap food particles, wet wipes, and other debris.

Main Sewer Line Blockages

Sometimes, the blockage isn't in your property's pipes but in the main municipal sewer line. Our experts can help identify the location of the issue and advise on the right course of action.

Our Process for Clearing Your Blocked Sewer

At GPS Gas & Plumbing Services, your trusted blocked sewer plumber in Sydney, we follow a meticulous process to ensure every sewer issue is resolved correctly and permanently.

1. Emergency Assessment: Our process begins the moment you call. We listen to the issues you're facing, such as sewage backup or multiple blocked drains, and dispatch a licensed plumber immediately to assess the situation.
2. CCTV Sewer Inspection: To find the exact cause and location of the sewer blockage, we insert a high-tech CCTV camera into the pipeline. This helps us identify the problem—be it tree roots, a collapsed pipe, or a severe clog—without any guesswork.
3. Powerful Sewer Clearing Solutions: Once we’ve identified the problem, we use the best method to clear the sewer. For most blockages, high-pressure jet blasting will flush the pipe clean. For severe tree root intrusion, we use specialised cutting tools to remove the obstruction completely.
4. Final Check and Prevention Advice: After clearing the blockage, we perform a final camera inspection to confirm the sewer line is clear and flowing freely. We'll also provide expert advice on how to prevent future sewer problems.

Our systematic approach guarantees an effective, long-lasting solution to your blocked sewer problem.

Signs You Have a Blocked Sewer

If you notice any of these signs, it could mean you have a serious blockage in your main sewer line. Contact us immediately to prevent a plumbing disaster.

Multiple Drains are Blocked

If your toilet, shower, and sinks are all draining slowly or not at all, the blockage is likely in your main sewer line, not an individual drain.

Sewage Backup in Drains

The most obvious sign of a blocked sewer is sewage or filthy water backing up out of your drains, typically at the lowest point in the house like a shower or floor drain.

Gurgling Noises from Toilets

When you flush a toilet or run water in a sink, do you hear strange gurgling sounds? This indicates trapped air in the plumbing system caused by a sewer line blockage.

Foul Odor in or Around Your Property

A persistent smell of raw sewage inside or outside your home is a clear warning sign that your main sewer line is blocked and potentially leaking. If you’re experiencing any of these issues, contact GPS Gas & Plumbing Services. Our blocked sewer experts are ready to solve the problem quickly.

How to Prevent Future Sewer Blockages

Be Careful What You Flush

The only things that should be flushed down the toilet are human waste and toilet paper. Never flush wet wipes (even "flushable" ones), sanitary products, paper towels, or cotton swabs, as they cause severe sewer blockages.

Dispose of Grease Correctly

Never pour fats, oils, or grease down your sinks. Let grease cool and solidify in a container, then throw it in the rubbish. This is the single best way to prevent grease-related sewer clogs.

Know Where Your Sewer Line Is

Be aware of where your main sewer line runs on your property, and avoid planting trees or large shrubs nearby. Tree roots are naturally drawn to the moisture in sewer pipes and are a primary cause of blockages. By following these tips, you can reduce the risk of a blocked sewer.

Jane Wills

Had a kitchen tap that wouldn’t stop dripping no matter how hard I turned it off. Called GPS Gas Plumbing Services and they booked me in the same day. He replaced the worn-out washer, tightened everything up, and even checked the other taps in the house to make sure they were fine. Really tidy job — left the bench clean and dry. Happy with the service.

FAQs

FAQs – Your Blocked Sewer Questions Answered

A blocked drain usually affects a single fixture (like a sink or shower), while a blocked sewer affects the main pipeline, causing issues across your entire property, such as multiple clogged drains and sewage backups.

We use high-pressure jet blasting and specialised root-cutting tools to completely remove tree roots from the sewer pipe. For a long-term solution, we may also recommend pipe relining to prevent them from growing back.

As the property owner, you are typically responsible for the sewer line running from your house to the point where it connects with the municipal main line. A professional plumber can help determine the location of the blockage.

The cost varies depending on the severity and location of the blockage. Jet blasting for a sewer line can range from $300-$800, while more complex repairs like pipe relining will cost more. We provide an upfront quote before any work starts.
