Best Heat Pump System Australia: What You Need to Know Before You Buy
If you’re considering a heat pump hot water system, you’re…
A blocked sewer is one of the most serious plumbing issues you can face. Unlike a blocked drain or blocked toilet, a sewer blockage can affect your entire property’s plumbing system. If left untreated, it can cause raw sewage to overflow into your home or garden, create serious health risks, and even damage your pipes.
At Off Grid Plumbing, we specialise in diagnosing and repairing blocked sewers quickly and effectively. Our licensed plumbers use the latest equipment – including CCTV drain cameras, high-pressure water jetters, and sewer locators – to find the cause of the blockage and clear it properly, without guesswork.
Not sure if your issue is a sewer blockage or just a small drain problem? Look out for these common signs:
Multiple drains blocking at once – If your toilet, shower, and sinks are all draining slowly, it usually points to a main sewer blockage.
Unpleasant smells – A strong sewage odour around your property or drains.
Gurgling noises – Bubbling sounds from toilets, sinks, or floor drains.
Sewage overflow – Wastewater pooling in your garden, driveway, or inside the home.
Toilet backing up – Flushing causes water to rise or come up elsewhere.
If you notice these warning signs, call us immediately before the issue escalates.
Blocked sewers can happen for several reasons. The most common causes include:
Tree root intrusion – Roots seek out moisture and can break into sewer pipes.
Build-up of fat, oil, and grease – These harden over time and block water flow.
Foreign objects – Wipes, sanitary products, and other non-flushables cause serious blockages.
Broken or collapsed pipes – Especially in older homes with clay or earthenware pipes.
Incorrect pipe installation – Poor gradients or misaligned joints can lead to frequent blockages.
Our team can identify the exact cause and recommend the best long-term solution.
Don’t let a blocked sewer cause damage to your home or risk your family’s health. Call Off Grid Plumbing today for fast, professional, and reliable blocked sewer services.

We use CCTV drain cameras to inspect your sewer line, pinpoint the blockage, and assess pipe condition.
Depending on the cause, we use high-pressure water jetting, mechanical drain clearing, or root cutting to remove the blockage.
If the sewer pipe is cracked, collapsed, or severely damaged, we can carry out: Pipe relining – Creates a new pipe inside the old one without excavation. Sewer replacement – Installing new sections of pipe if the damage is too extensive.
Common signs include multiple drains in your home backing up at once, foul odours coming from sinks or toilets, gurgling sounds in the pipes, or wastewater overflowing from drains outside. If you notice any of these, it’s important to act quickly before the problem worsens.
Sewers often become blocked due to tree root intrusion, build-up of grease and fat, foreign objects being flushed, or collapsed/damaged pipes. Over time, even natural debris like dirt and leaves can cause blockages if not maintained.
Minor clogs in household drains might be cleared with a plunger, but a blocked sewer requires specialist equipment such as CCTV drain cameras and high-pressure water jetting. DIY attempts can make the problem worse or mask a bigger underlying issue.
We start with a CCTV drain inspection to locate the exact cause and location of the blockage. Depending on the issue, we use high-pressure jetting, root cutting tools, or mechanical equipment to clear it. If the pipe is damaged, we may recommend pipe relining or replacement to prevent future blockages.
The cost depends on the severity and cause of the blockage. A simple jetting service may be relatively quick and affordable, while major issues like collapsed pipes or extensive tree root intrusion may require more extensive repairs. We always provide an upfront, transparent quote before starting work.
