Winter in Melbourne can be unpredictable, with cold fronts and temperature drops that often lead to plumbing issues—particularly burst pipes. As a trusted plumber Melbourne residents rely on, we often see a spike in burst pipe callouts during the colder months. This blog will walk you through practical steps to safeguard your plumbing system against winter damage and help you understand why this is crucial for Melbourne homeowners.

Why Do Pipes Burst in Winter?

When temperatures drop, any water sitting inside exposed or poorly insulated pipes can freeze. As water turns to ice, it expands, putting enormous pressure on the pipe walls. Eventually, this pressure can cause the pipe to crack or burst, leading to water damage, flooding, and costly repairs.

Practical Tips to Prevent Burst Pipes:

Insulate Exposed Pipes
Use foam pipe insulation, heat tape, or lagging on outdoor pipes, pipes in basements, and under sinks. This will help keep the internal temperature stable.
Leave the Heater On Low
Keeping your home’s temperature consistent—even when you’re away—can prevent indoor pipes from freezing. A low thermostat setting overnight or while on holiday is often enough.
Fix Leaks Immediately
Drips and small leaks may seem minor, but they can freeze and worsen during winter. Promptly repairing them reduces your risk of burst pipes.
Let Taps Drip During Extreme Cold
A small, continuous flow of water keeps pressure from building up. This trick is especially useful for pipes that run along exterior walls.
Disconnect Outdoor Hoses
Water left in hoses can freeze and expand into the spigot and connected pipes. Always drain and store hoses before winter.
Seal Gaps and Cracks
Check for holes or gaps near pipework in walls and floors. Seal them with caulking or expanding foam to reduce drafts that lower pipe temperatures.

What to Do If a Pipe Freezes

If you suspect a frozen pipe (reduced water flow or no flow at all), you should:

Turn off the main water supply.
Apply warm towels or a hairdryer (on low) to gently thaw the pipe.
Never use an open flame.
Call a licensed plumber in Melbourne to inspect the damage and repair or replace the affected sections.
