Drain Clearing Guide
What to Do About a Blocked Drain
Learn how to recognise a persistent drainage blockage, what information to prepare and when professional drain clearing is more appropriate than repeated household fixes.
Common Symptoms
How can you recognise a blocked drain?
A persistent blockage often affects more than one part of a drainage system.
Standing wastewater
Wastewater remains around a drain or backs up after water is used elsewhere on the property.
Recurring blockages
The same drain keeps blocking even after temporary clearing or cleaning.
Before Calling
Information that helps the service team
Exact property location and easiest access route.
Which drain or line is affected.
Whether the problem is slow drainage, standing water, overflow or repeated blockage.
Whether the issue affects one outlet or several connected areas.
Avoid making the blockage worse
Do not repeatedly add large amounts of water to a backed-up system. Avoid unsafe attempts to open underground chambers or enter confined spaces. If wastewater is overflowing, keep people and pets away from the affected area.
