How to Reduce Water Damage While Waiting for an Emergency Plumber

Key Takeaways

• Turn off the water at the stop tap near your meter first, then check for electrical and gas hazards before you start containing the leak.
• Water near switches, power points or light fittings is dangerous, so switch off power to the area if it is safe and leave wet wiring to a licensed electrician.
• Photograph and film the damage before cleaning up and tell your insurer as soon as possible, because the Insurance Council advises not starting repairs until you have spoken to them.
• Call an emergency plumber straight away if the water cannot be stopped, is near electrics or you smell gas, and avoid DIY repairs beyond temporary containment.

 

The fastest way to reduce water damage while waiting for an emergency plumber is to turn off the water at the stop tap, make electricity safe, then contain the water and move belongings out of its path. Photographing the damage before you clean up and telling your insurer early protects any claim you make. Melbourne homeowners who need an emergency plumber Melbourne can call at any hour, but what you do in the minutes before the plumber arrives often decides how much damage the leak causes.

Water emergencies are common in Victoria. RACV recorded 17,794 plumbing emergencies across the state between April 2025 and March 2026, according to RACV’s plumbing guide. The steps below cover what to do first, how to stay safe and how to protect your home and your claim.

What should you do first when water is leaking in your home?

Stop the water at its source first, then check for electrical and gas hazards, and only then start containing the water. Following that order keeps you safe and stops the leak growing while you tidy up.

If the leak comes from a single fixture such as a toilet or basin, close that fixture’s isolation valve. If the source is unclear or the leak is serious, turn off the water at the stop tap near your meter, because shutting off the whole house supply is always the safer choice when you are unsure which valve controls the leak. Next, look for water near switches, power points or light fittings, and listen and smell for gas. Once the water is off and the area is safe, start moving belongings and soaking up water.

How do you turn off the water at the mains in Melbourne?

In most Melbourne houses, the water meter sits outside near the front gate or fence, and the stop tap is next to it. South East Water’s guidance says the meter is usually near the front gate or fence, and that you can turn off the supply at the stop tap near it while waiting for repairs. Units and townhouses may share a meter, in which case building management or the owners corporation needs to be contacted.

If the tap is stiff, Yarra Valley Water’s page suggests turning it anticlockwise first to break the seal, then clockwise to close it. Which retailer services your home depends on your address, so check your water bill. Locating the stop tap before an emergency, and making sure everyone in the household knows where it is, saves valuable minutes.

Is it safe to use electricity when there is leaking water?

Treat any water near electrical fittings as dangerous. If you can do it safely, switch off power to the affected area at the switchboard, and keep away from wet outlets, cords and appliances. Never touch electrical equipment while standing in water or with wet hands.

According to Energy Safe Victoria’s guidance, you should not use an electrical appliance, sink or bath if you feel a shock or tingling from any metal or plumbing. Leaks through ceilings are especially risky because water can reach light fittings and wiring you cannot see. If water has reached wiring, power points or the switchboard, have a licensed electrician check the system before power is restored. If you smell gas at any point, leave the area, avoid flames and switches, and treat it as an emergency.

What should you do for each type of leak?

The right first action depends on where the water is coming from. A burst pipe needs the mains turned off, while a hot water system leak also involves the power or gas supply to the unit.

For a pipe that has split under pressure, Prowater’s guide on when a pipe bursts walks through each step in detail. If a hot water unit is the source, learn how to safely shut off hot water units before touching them.

How do you protect your floors and belongings?

Move furniture, electronics and valuables out of the wet area first, then limit the spread of water with towels and buckets. Protecting items early costs very little and often saves far more than the clean-up later.

• Lift and relocate: Move electronics, paperwork, rugs and soft furnishings to a dry room, and lift boxes and stored items off the floor.
• Contain and soak up: Place towels along doorways, put buckets under drips and soak up pooled water with towels or a mop, keeping clear of any live power.
• Ventilate: Open windows and doors to start drying the area, because retained moisture is what allows mould to develop.

Should you take photos and tell your insurer?

Yes. Photograph and film the damage before you clean up, and tell your insurer as soon as possible. The Insurance Council guidance advises documenting water damage with photos and videos before starting clean-up, reporting it to your insurer as soon as possible and not starting repairs until you have spoken to them.

Useful photos include the source of the leak, how far the water has spread, and damaged items before you move them where it is safe to do so. Keep receipts for any emergency work. Leaks are a common claim trigger: Suncorp’s flexi-hose research found that one in ten home insurance claims in 2025 were caused by flexi-hoses, even though a flexi-hose costs less than $20 at a hardware store. Suncorp also advises turning the water off at the mains if you are leaving the house for more than 24 hours.

What should you avoid while waiting for the plumber?

Avoid anything that adds an electrical, gas or structural risk, and leave pipework, gas fittings and switchboards to licensed tradespeople. The aim is to hold the damage steady until the plumber arrives, not to repair the fault yourself.

• Using wet electrical equipment: Do not switch on appliances, touch wet outlets or use powered tools near standing water.
• Attempting a permanent repair: Tape or a clamp may slow a leak briefly, but the plumber needs to see the original failure, and a poor temporary fix can make the repair harder.

Do not assume that a leak that has slowed down has fixed itself. A reduced drip can still be releasing water into walls, ceilings or subfloors where you cannot see it.

When should you call an emergency plumber instead of waiting?

Call an emergency plumber straight away if the water cannot be stopped, is near electrical equipment, or you smell gas. A contained, slow leak can usually wait for normal business hours. Prowater’s guide to calling an emergency plumber explains how to tell urgent faults from ones you can book.

When you ring, tell the plumber what you can see, where the water appears to be coming from, whether you have turned off the water and power, and whether anyone has felt a shock or smelled gas. That information helps the plumber bring the right parts and plan the fastest response. A plumber can also tell you whether the job can safely wait until business hours.
