Burst Pipes in Melbourne Winter: What To Do in the First 5 Minutes

Why Melbourne Winters Are Brutal on Pipes

Melbourne might not get the deep freezes of the alps, but our winter nights regularly drop low enough to put serious stress on plumbing — especially in older weatherboard homes, sheds, and exposed external pipework. Add in sudden temperature swings between night and day, and you've got the perfect recipe for cracked joints and burst pipes.

Every July and August we get a spike in emergency call-outs (0400 362 044) for the same thing: a homeowner waking up to water pouring through a ceiling or pooling under the house.

The good news? What you do in the first 5 minutes makes a massive difference to how much damage you're left with.

Minute 1: Shut Off the Water at the Mains

This is the single most important step. Forget mopping, forget calling anyone — get to your main water shut-off valve and turn it clockwise until it stops.

In most Melbourne homes, the mains tap is:

At the front of the property near the water meter (often in a small green box in the lawn or footpath)

Sometimes located under the kitchen sink or in the laundry on newer builds

If you've never located yours, do it tonight — not in an emergency. Show every adult in the house where it is.

Minute 2: Kill the Power to Affected Areas

Water and electricity are a deadly combo. If water is anywhere near power points, light fittings, the meter box, or appliances:

Go to your switchboard and flip the main switch off

If the switchboard itself is wet — do not touch it. Stand clear and call an electrician

Never wade through standing water near electrical fittings. It's not worth it.

Minute 3: Open Taps to Drain the System

Once the mains is off, open the lowest taps in the house (usually outside taps, or a laundry tub) and let the remaining water in the pipes drain out. This relieves pressure and slows the leak from the burst point.

Don't forget to flush the toilets once each to clear the cisterns.

Minute 4: Contain the Damage

Now you can start protecting your stuff:

Move furniture, rugs, and electronics away from the affected area

Lift curtains off the floor and drape them over the rod

Use buckets, towels, and tarps to catch active drips

If water is pooling on a ceiling, poke a small hole in the lowest sag with a screwdriver to drain it into a bucket. This sounds counter-intuitive but it prevents the whole ceiling collapsing

Minute 5: Call a Licensed Plumber

This is when you ring us. 0400 362 044 — we answer 24/7, and we cover all of Melbourne.

When you call, have ready:

Your address and nearest cross street

Where the burst is (kitchen, bathroom, under house, in the ceiling)

Whether you've shut the mains off already

Whether there's any electrical risk

The more we know, the faster we can get the right gear on the truck.

What NOT To Do

Don't try to patch it with tape or epoxy unless you genuinely know what you're doing — a botched patch can blow off under pressure and make things worse

Don't ignore a "small" leak — pinhole bursts almost always get bigger, fast

Don't turn the mains back on to "check if it's still leaking" — you'll just flood again

Don't run the hot water system dry — if your burst is on the hot side and the tank empties, the element can burn out

How to Stop It Happening Next Winter

A few cheap steps now save thousands later:

Lag exposed pipes — foam pipe insulation from Bunnings costs about $5 per metre and takes minutes to fit

Disconnect garden hoses — before the first frost — water trapped in the hose freezes and cracks the tap

Service your hot water system annually — old, corroded tanks are a top cause of winter bursts

Get a [SmartCare Maintenance Plan](/maintenance-plans) — we'll do a pre-winter check and catch the weak points before they let go

The Bottom Line

A burst pipe is stressful, but it's not the end of the world if you act fast. Mains off, power off, drain the system, contain the damage, call a plumber. Five minutes of the right action can save you tens of thousands in water damage and insurance excess.
