You need an emergency plumber when a fault cannot safely wait because it threatens people, is causing substantial property damage or has cut off an essential water or sanitation service. Examples include an uncontrolled leak, burst pipe, sewage backup or an overflowing toilet that cannot be contained.
Attendance time depends on technician availability, your location, traffic, site access and the hazards reported during the call. The plumbing service should triage the fault and give you a realistic estimated arrival time. If there is an immediate threat to life, fire or a serious electrical or gas hazard, move to safety and call Triple Zero (000) rather than waiting for a plumber.
When to call an emergency plumber
Call for urgent help when water or wastewater is uncontrolled, unsafe or seriously disrupting essential services:
- Burst pipe or major leak: Water is spreading through floors, walls or ceilings, or continues after you have safely isolated the relevant water supply. Keep clear if water is near electrical fittings; do not touch switches, appliances or wiring.
- Blocked drain or sewage backup: Wastewater is overflowing, sewage has entered the property or the only usable toilet is out of service. Keep people and pets away, stop using affected fixtures and do not use chemical drain cleaners.
- Overflowing toilet: The overflow continues after you have stopped flushing and closed an accessible isolation valve, or wastewater is backing up through other fixtures.
- No running water: Check Sydney Water’s current outage information first. If nearby properties still have water and your property has no practical supply for drinking or sanitation, arrange prompt assessment.
- Hot-water system fault: A loss of hot water alone can usually wait for a routine appointment. Seek urgent help if the unit is leaking significantly, water is near electrical components or you smell gas.
- Suspected gas leak: Leave the property and move to fresh air. Do not use flames, electrical switches or a phone inside. From a safe location, call 000 if there is immediate danger; otherwise contact your gas distributor’s emergency line. Do not attempt repairs.
A dripping tap, slow drain or fault affecting one fixture is generally not a plumbing emergency if it is contained, creates no immediate safety risk and leaves essential facilities available.
What to do while waiting
If it is safe, stop using the affected fixture and close its accessible isolation valve. For an uncontrolled clean-water leak, turn off the property’s main water supply only if you can reach it safely.
- Keep people and pets away from sewage, flowing water, sagging ceilings and flooded areas.
- Use containers or towels for clean water only when there is no electrical, contamination or structural risk.
- Do not enter water near electrical equipment or touch affected switches. Move away and call 000 for immediate danger, or your electricity distributor for emergency assistance.
- Do not dismantle pipes, hot-water systems or gas appliances. Repairs involving regulated plumbing or gasfitting must be completed by an appropriately licensed NSW tradesperson.
- Tell the plumber what is leaking or overflowing, whether the water is isolated, and whether sewage, gas or electricity is involved.
