It’s 11pm. You hear rushing water. You walk into the hallway and see it: a gushing pipe spraying water across the floor, soaking into the carpet, spreading toward the bedrooms. Your plumber says 45 minutes. Maybe longer.
What you do in the next five minutes determines whether this stays a manageable repair or becomes thousands of dollars in structural damage, ruined belongings, and insurance headaches. The difference between contained and catastrophic isn’t luck. It’s knowing exactly what to do right now.
You’re probably stressed. That’s normal. But emergencies can happen anytime, anywhere, and often without warning, and panic doesn’t help. Action does. These five specific steps will minimise damage, protect what matters, and set you up for the fastest possible repair once help arrives.
Here’s what happens minute by minute. No guessing. No wasted movement. Just clear actions that work.
The First 60 Seconds: Turn Off the Water (Here’s Exactly Where to Look)

Every second water flows equals more damage. More soaked carpet. More water seeping into walls. More risk of it reaching the room below. Stopping the source is always step one. Not cleanup. Not photos. Not calling anyone. Stop the water first.
You have two options: shut off the main valve to stop all water to the house, or use a fixture shut-off if the problem is isolated. Which one you choose depends on where the leak is and how fast you can find the valve.
Finding your main shut-off valve right now (before you need it)
Most Australian homes have the main water shut-off in one of three places. Check near the water metre at your front boundary, in the garage, or under the kitchen sink. It’s typically a round wheel valve or a lever-style tap, sometimes with a small metal tag attached.
To shut it off, turn the wheel clockwise until it stops. If it’s a lever, flip it so it sits perpendicular to the pipe. That’s it. Water stops.
If you’re reading this before an emergency, go find it right now. Mark it with bright tape. Tell everyone in the house where it is. When water is spraying at midnight, you don’t want to be searching.
When to use fixture shut-offs instead of the main valve
If the problem is isolated to one fixture, a leaking toilet, a dripping tap, a washing machine hose, there’s usually a shut-off valve right there. Look under sinks, behind toilets, on the wall behind washing machines. These small valves let you stop water to that one fixture while keeping the rest of the house running.
The advantage is obvious: you contain the problem without cutting water to the whole house. But here’s the rule: if you can’t find the fixture valve in 30 seconds, don’t waste time. Go straight to the main shut-off. Speed matters more than convenience.
Minute 2: Stop the Spread — Protect What Matters Most
You’ve stopped the source. Now deal with what’s already flowing or pooling. You’re not fixing anything yet. You’re buying time and protecting your belongings from water that’s spreading across floors, seeping into walls, or dripping through ceilings.
Speed beats perfection here. Grab what’s in reach and focus on keeping water away from electronics, documents, and anything that can’t be dried or cleaned later. For more guidance on managing burst pipes specifically, see our detailed guide on What To Do When You Have A Burst Pipe.
Moving electronics and furniture out of water’s path
Prioritise in this order: electronics first, important documents second, furniture third. Unplug devices before you move them. Lift items onto beds or tables. Move rugs and mats out of the way.
Don’t waste time on things that can be cleaned or dried later. A wet cushion is annoying. A soaked laptop is a loss. If water is already deep, don’t try moving heavy furniture. Focus on smaller, valuable items you can actually shift quickly.
Using towels, buckets, and whatever’s in reach to redirect flow
Bath towels work as temporary dams. Roll them up and place them to direct water toward drains or away from carpeted areas. Put buckets under active drips. Use plastic bins to catch overflow from sinks or toilets.
If you don’t have enough towels, use mops, squeegees, even rolled-up newspapers. This isn’t cleanup. You’re just preventing spread until the plumber arrives. Temporary containment is the goal.
Minute 3: Cut the Power (But Only If It’s Safe)

Water and electricity together can cause electrocution or fire. If water is near power points, appliances, or light fixtures, you need to cut power to that area. But only if you can reach the switchboard without stepping in water.
This step prevents immediate danger and long-term damage to wiring and appliances. Don’t panic. Just treat it as a precautionary step when water is within striking distance of anything electrical.
When water and electricity mix: the signs you need to act
Watch for these warning signs: water near power points, sparking sounds, lights flickering, water pooling near appliances. If water is within one metre of any electrical outlet or appliance, treat it as urgent.
Ceiling leaks above light fixtures are particularly dangerous. Water can travel along wiring inside the ceiling cavity. If you see water dripping from a light fitting, cut power to that circuit immediately.
Don’t touch anything electrical if water is already present. Go straight to the switchboard.
How to safely switch off circuits without touching wet areas
The safest approach is flipping the main switch at your switchboard to cut all power to the affected area. Switchboards are typically in the garage, laundry, or near the front door. If you know which circuit breaker controls the affected room, you can switch off just that one.
Never touch the switchboard with wet hands or while standing in water. If you can’t reach it safely, leave it and call an electrician. Your safety matters more than preventing electrical damage.
Minute 4: Document Everything (Your Insurance Claim Starts Now)

Insurance claims require evidence. Memories fade. Details blur. What seems obvious now won’t be obvious in three weeks when you’re filling out forms and trying to remember exactly what happened.
This is a two-minute investment that could save thousands in disputed claims. Quick phone photos and brief notes are enough. You don’t need a formal report. Just enough detail to support your claim later.
What to photograph and video before the plumber arrives
Capture the source of the leak, water damage to floors and walls, damaged belongings, and your water metre showing usage if it’s spiking. Take wide shots showing the full extent of damage, then close-ups of specific problems.
A quick video walkthrough works well. Narrate what happened and what you can see. Timestamp everything by checking your phone’s camera settings are set to auto-date. Insurance assessors want proof of when the damage occurred.
Quick notes that make insurance claims easier later
Use phone voice notes or send yourself a quick text with key details. Record the time the problem started, what you were doing when you noticed it, and the immediate actions you took.
Note any unusual sounds, smells, or warning signs that preceded the emergency. Did you hear banging pipes? Smell something odd? These details matter when establishing cause and timeline. Don’t write a formal report. Just enough to jog your memory later.
Minute 5: Prepare for the Plumber (So They Can Work Fast)
Reducing the plumber’s time on-site directly reduces your emergency callout cost. If you’re concerned about pricing, check our breakdown of How Much Does A Plumber Cost In Sydney. Plumbers work faster when they can access the problem immediately and understand what happened.
This is the same principle as preparing for paramedics: clear access and ready information mean faster, more effective help. Simple preparations make a real difference.
Clearing access to the problem area and your water heater
Move boxes, furniture, and stored items blocking the affected pipes or water heater. Secure pets in another room so the plumber can work safely and quickly without distractions.
If the problem involves external pipes or metres, turn on outdoor lights. If it’s an after-hours callout, unlock gates and clear a path from the street to the house. Every minute the plumber spends navigating obstacles is a minute they’re not fixing the problem.
What details to have ready when they walk in the door
Have this information ready: when the problem started, what you’ve already done, where the main shut-off is, and any relevant history with the system. Have your phone ready to show the photos and videos you’ve taken.
If the problem involves hot water, know your water heater age and type. Don’t try diagnosing the technical cause. Just provide clear facts about what happened and what you observed. The plumber will handle the diagnosis.
You’ve Bought Yourself Time — Now Use It Wisely
These five minutes determine whether damage stays contained or spreads throughout the house. Water doesn’t wait. It finds every gap, every seam, every weakness in your floors and walls. But you now have a clear plan that turns panic into purposeful action.
Walk through these steps now, before an emergency. Locate your shut-off valves. Mark them. Make sure everyone in the house knows where they are. Know where your switchboard is. Have a plan for moving electronics quickly.
Emergencies happen without warning. But preparation means you’re ready when they do. And if you need help with minor blockages while you wait, our guide on How To Use A Plunger covers quick fixes for common drainage issues.
