Blocked Drains: Causes, Symptoms & Troubleshooting

Blocked drains are among the most common plumbing problems in Central Coast homes. Toilets, sinks, showers and underground sewer pipes can become blocked by grease, hair, foreign objects, tree roots or damaged pipework.

These guides explain how to recognise a blockage, what you can safely check yourself and when professional drain clearing may be needed.

Gurgling Drains

CCTV Drain Inspections, Tree Roots & Underground Pipes

Some drainage problems cannot be diagnosed by looking at the affected sink or toilet. Underground sewer and stormwater pipes may be affected by root intrusion, damaged joints, collapsed sections or accumulated debris.

Professional CCTV drain cameras and pipe-location equipment can help identify the condition and location of underground drainage problems.

Our guides explain common plumbing emergencies, factors affecting repair costs and possible causes of hot water failures.

When Should You Call a Licensed Plumber?

Some minor plumbing issues can be checked safely at home. However, recurring blockages, sewage backups, overflowing drains, suspected underground pipe damage and problems involving gas or electrical components should be assessed by qualified professionals.

If multiple plumbing fixtures are backing up, wastewater is overflowing or the same drain repeatedly becomes blocked, avoid using the affected fixtures until the problem has been investigated.
