Do I Have A Major Or Minor Blocked Drain?


A Blocked Drain is a common plumbing problem but knowing if it is a major or minor blocked drain will help with knowing how to deal with it. Minor blockages are often clogs where the drain is partially blocked, such as hair blockages. Major blockages are where the system is almost or is fully blocked and nothing can go past. Here at The Local Plumber, our Emergency Plumber team is here to quickly unblock any major or minor blocked drain in Melbourne. 

To know if you have a major or minor blocked drain look for these signs:

  • Minor – slow draining, foul smells, gurgling sounds
  • Major – slow draining, foul smells, gurgling sound, water stagnant, backup

What are the Signs of a Major or Minor Blocked Drain?

The main signs to look out for that will help indicate whether you have a major or minor blocked drain are:

Slow Draining

If the drains, sinks and other systems take longer to drain water and other content then this is a sign of a blockage. It could mean that the drain is partially or almost fully blocked meaning it takes longer for them to drain out of the system. Both minor and major blockages can experience this issue of slow draining. The slower the water takes to drain means the larger the blockage is

Foul Smells

If there are any unpleasant or foul smells that are coming from the drain then there is a good chance that a blockage is inside. Minor and major blockages will often result in these bad odours forming. Food bits, oil, grease, hair, soap and other blocked content mean that they can develop horrible smells. When water enters the drain then the smell will often become worse as the bacteria becomes aggravated.

Gurgling Sounds

When the tap, toilet or drain is used and if a gurgling sound occurs then a clog is often the reason for this issue. Any air that is trapped by the blockage, both minor and major, will be pushed up when the drain is used and cause the sound to occur. The louder the gurgling sound means that more air is trapped in the drain from the blockage. 

Water Is Stagnant

If water does not pass through the drain then there is a major blockage in the system. Large blockages, such as tree roots or major food blockages, can lead to the whole pipe being clogged. This can result in the blockage being so large and tough that water and other content cannot flow through. If the water stays at the drain opening or does not easily go down the drain then there could be a major blockage.


If sewer or other content backs up into the home then this is a clear sign of a major blockage. Whether the blockage is from wipes, food bits or tree roots, the type of blockage is preventing water and content from easily flowing through the pipes. This means that it can flow back up from the drain and back into the building. Whenever there is water or sewer backup then it is important to address the problem as soon as possible.
