Blocked drain FAQs for Collaroy
Who arranges access for a Collaroy unit blockage?
The strata manager or owners corporation may need to arrange access where the affected pipe serves multiple lots or sits in common property.
Does rain-only pooling mean a sewer fault?
Not by itself. Inspect the nearest grates, pits, downpipes and stormwater path separately from toilets and floor wastes.
What does CCTV add after flow is restored?
It can record the obstruction, condition and fault position when recurrence or repair decisions require evidence.
