Quick answer: Call an emergency plumber when a fault is causing active water damage, creating a health or safety risk, or stopping an essential service. The most urgent calls are usually burst pipes, sewage backups, overflowing toilets, major leaks and sudden failures that are getting worse quickly.
Use this guide to understand the likely causes, the warning signs worth acting on and the questions to ask before approving a repair. Every property is different, so the final recommendation should be based on what is actually found on site.
1. A burst pipe or active flooding
Water spraying from a pipe, running through a ceiling or pooling quickly inside the property needs fast attention. If it is safe and you know how, isolate the affected water supply and move valuables away from the wet area. The plumber can then identify the failed section and make a repair based on the cause rather than simply slowing the leak.
2. Sewage is backing up through fixtures
Sewage coming through a toilet, shower or floor waste is more than an inconvenience. Stop using connected fixtures because extra water can worsen the overflow. A blocked-drain plumber may need to clear the line and inspect it with CCTV to determine whether the cause is a local blockage, tree roots or damaged pipework.
3. Multiple drains fail at the same time
One slow basin may be a small local issue. Several fixtures gurgling, draining slowly or backing up together can point to a blockage further down the drainage system. This is particularly important if the symptoms are worsening or there are sewage odours.
4. You hear water running but cannot find it
A concealed leak can waste water and damage building materials before a visible stain appears. A moving water meter, bubbling paint, unexplained dampness or a persistent wet smell are reasons to arrange leak detection rather than waiting for the source to reveal itself.
5. A toilet will not stop overflowing
If the water level is rising, stop flushing. Turn off the toilet isolation valve if it is safe and accessible. Repeated flushing can push contaminated water onto the floor. If a basic plunge does not solve the issue, professional drain-clearing equipment may be required.
6. The hot water system has failed suddenly
No hot water is not always an emergency, but it can become urgent for families, businesses and properties where the unit is also leaking. If the tank or connected pipework is releasing water, arrange an assessment instead of continuing to run the system.
7. You suspect a gas leak
If you suspect a gas leak, avoid flames, smoking and electrical switches in the affected area. Move to a safe location and contact the appropriate emergency or gas service, then use a licensed gas fitter for relevant plumbing repairs. Do not attempt to locate or repair a gas leak yourself.
8. Stormwater is entering the building
Water entering a garage, subfloor or lower level during rain may point to blocked pits, downpipes or stormwater lines. Once the immediate water is controlled, the drainage system should be checked for the underlying restriction or design issue.
9. Water is close to electrical fittings
Water around lights, switchboards, power points or appliances creates an extra hazard. Keep clear of the affected area and do not touch wet electrical equipment. Depending on the situation, both a plumber and electrician may be required.
