Know the signs to take action on blocked sewers
Blocked sewers are a safety risk for your home or office. Stay alert by knowing the signs, so our team can catch the problem early.
Foul odours
A strong smell coming from your drains, similar to rotting waste, is a classic warning sign.
Water overflow
Water backing up in the shower, sink or basement can mean major sewer line obstructions.
Multiple clogged fixtures
Many clogged drains at once is a key sign of a blocked sewer line rather than a single blocked drain.
Noticed a blocked sewer? Take prompt action — depending on where the block sits in your property boundary, we'll point you to the right fix or the right authority.
Our guide to preventing sewer blocks
From the environment to skipped maintenance, there are many reasons behind a blocked sewer. Keep yours in the right condition with these steps:
Grease and oil build-up
Fats poured down the drain solidify in the pipes and cause blockages — dispose of them in the bin instead.
Foreign objects
Wet wipes and sanitary products belong in bins. Flushing them is one of the fastest ways to clog a sewer.
Tree root intrusion
Plant trees away from sewer lines and consider root barriers to reduce the risk of roots invading your pipes.
Annual professional inspection
Blocked sewers are common after heavy rainfall. A yearly inspection helps keep the sewer operating smoothly.
Our flexible approach to blocked sewers
Every blocked sewer gets a tailored solution. We start with a comprehensive CCTV camera inspection to pinpoint the cause, then choose the right fix:
- 1
CCTV camera diagnosis
Cameras inserted into the drains give us real-time footage, so we can accurately locate the blockage and its cause before any work begins.
- 2
High-pressure water jetting
Our jetting technology releases water at up to 5,500 PSI through a long flexible hose — powerful enough to clear obstructions of any size.
- 3
Pipe relining
A hassle-free alternative to excavation: epoxy resin applied inside the pipe returns it to near-new condition in a fraction of the time.
- 4
Chemical root treatment
For tree root intrusion we use ROOTX, a powerful treatment that penetrates and cuts through root blockages, leaving pipes clear and functional.

Blocked sewer FAQs
The questions Melbourne home and business owners ask us most about blocked sewers.
Can you fix a clogged sewer line yourself?
In most cases, no — addressing sewer blockages requires licensed plumbers and expert tools. For advice on your specific situation, get in touch with the Mr Drainage team.
Who is responsible for a blocked sewer?
It depends on where the blockage sits. Within your property boundary it's the property owner's responsibility; outside the boundary, the local water authority handles the work. We can help you determine which applies.
What's the difference between a blocked drain and a blocked sewer?
A sewer block affects the entire household and can cause widespread problems, while a blocked drain usually affects one area at a time — a single sink, shower or toilet.
How long will it take to clear a sewer block?
It depends on the severity. Simple blocks can be cleared in a few hours, while larger blockages can take a day or longer.
