Melbourne winters are notorious for their unpredictable, chilly temperatures, with night time temperatures often dropping below freezing. While the crisp mornings can be refreshing, they also bring a higher risk of plumbing problems, especially burst pipes. Frozen pipes can lead to significant water damage and expensive repairs.
To help you avoid these issues, here are some tips on how to protect your pipes during Melbourne’s cold winter months.
Why Do Pipes Burst in Winter?
Pipes burst when the water inside them freezes and expands, creating pressure that can crack or burst the pipe. This is common in areas with exposed pipes, like outdoor taps, unheated garages, or pipes along external walls. The risk increases when temperatures remain below zero or drop suddenly, as often happens in Melbourne winters.
Insulate Exposed Pipes
Insulating vulnerable pipes is one of the most effective prevention methods. Pipes in outdoor areas, crawl spaces, or along external walls are at higher risk. Insulating materials, such as foam sleeves or fiberglass, help keep pipes warmer. For additional protection, use heat tape, which keeps pipes warm through a small electrical current. Insulating exposed pipes reduces the likelihood of freezing.
Keep the Heat On
Even if you’re away for a while, keep your heating system on at a minimum of 15°C to maintain warmth throughout your home. For unheated areas like garages, use space heaters or heating cables to keep vulnerable pipes warm.
Let Taps Drip
During extreme cold, allow one or two taps to drip slowly. Moving water is less likely to freeze than stagnant water, so a small flow helps prevent blockages from ice. Focus on letting one or two taps run overnight to reduce the risk.
Seal Gaps and Cracks
Cold air can enter through gaps around windows, doors, and vents, increasing the risk of frozen pipes. Seal any cracks around your home using caulking, weather stripping, or foam sealant. Check for drafts around outdoor pipes, especially taps, and install insulated covers to protect them.
Disconnect and Winterise Outdoor Taps
Outdoor taps are highly vulnerable in winter. Turn off the water supply to these faucets, disconnect hoses, and store them for the season. If your taps have shut-off valves, close them and drain the pipes. Consider outdoor faucet covers to further protect them.
Regular Plumbing Maintenance
Schedule a plumbing inspection before winter arrives. A licensed plumber can check the condition of your pipes, identify risks, and ensure everything is in good working order. Replacing old or cracked pipes before the cold weather sets in can prevent major issues.
Know the Signs of Frozen Pipes
Be alert for signs of frozen pipes, including frost or condensation on pipes, reduced water pressure, or strange sounds. If you suspect frozen pipes, thaw them carefully with a hairdryer or space heater. Avoid using open flames, as they can damage pipes. If needed, call a plumber.
