5 Tips to Prepare Your Plumbing for Winter

03 February, 2025

Even here in sunny Australia, winter can be tough on your plumbing including pipes, fixtures and appliances. But never fear, with a little preparation you can prevent costly damage, ensuring your home stays warm and functional throughout the season.

And that's what we're going to share with you in this article; five practical winter plumbing tips to keep your plumbing in optimal health as the cold sets in.

What Impact Does Sydney Weather Have on Plumbing?

Even though Sydney’s weather is known for its mild winters, sudden cold weather snaps can still create issues for your plumbing. Even without freezing cold, extremely fluctuating temperatures combined with seasonal rainfall can stress your pipes. Warm air and quickly turn to cool air and understanding how to winterise your plumbing can be beneficial to avoid unexpected issues.

There are several measures you can take to keep your plumbing in top condition, protect your home and provide peace of mind throughout the cooler months.

1. Check for Issues and Insulating Exposed Pipes

First things first, before winter fully sets in, inspect your plumbing system for any potential issues.

Look for exposed pipes, leaks, corrosion and any other vulnerabilities. Pay special attention to unheated areas like basements, crawl spaces, and attics, as indoor plumbing in these spaces is particularly prone to the cold.

One way to protect your plumbing is to insulate exposed pipes with foam pipe insulation. This simple and cost-effective solution helps maintain a stable temperature and prevents pipes from freezing.

2. Protect Outdoor Plumbing

Outdoor plumbing is the most vulnerable during winter, but there are preventive measures you can take. As winter approaches, start by disconnecting and draining outdoor garden hoses to avoid hidden freezes that can lead to burst pipes.

Next, shut off the outdoor water supply with the primary shutoff valve to safeguard sprinkler systems and faucets from freezing temperatures. You might also want to get up on your ladder and check for roof leaks and any clogged gutters as the water build-up is more prone to freezing temperatures.

While not completely necessary for Sydney, to add an extra layer of protection, you can insulate outdoor faucets and exposed pipes with covers or foam insulation. If you choose to DIY you can get these materials from your local Bunnings. The extra layer of defence helps prevent freezing and bursting.

3. Seal Cracks and Gaps to Prevent Cold Air

Take a walk around your home and check for gaps or cracks where pipes enter the walls—these sneaky openings can let cold air in and create big problems when temperatures drop.

The fix is simple: grab some caulk or spray foam and seal those cracks tight. Not only will this protect your plumbing, but it’ll also keep your home warmer and more energy efficient.

4. Inspect Your Water Heater

Before the chill sets in, you'll want to check your hot water system. After all, there's nothing worse than a cold shower on a chilly winter morning! Look for signs of wear, leaks, or unusual noises that could indicate trouble.

If you're unsure, consider enlisting the help of a professional. Not only does it offer peace of mind, but it can also extend the lifespan of your hot water system, save you heating costs and, most importantly, ensure your hot shower doing the winter chill!

5. Prevent Frozen Pipes

Now, in the rare case that temperatures do drop towards zero, you may be worried about pipes freezing. Never fear, there's an easy trick: let your faucets drip slightly. This is because the movement of water, even just a trickle, helps prevent pipes from freezing. You only need to apply this for pipes located along exterior walls.

After a longer-term solution to avoid frozen pipes? Consider insulating your pipes. While there’s an upfront cost, it’s a smart investment for your home's plumbing system compared to the expense of wasted hot water. Or worse, repairing burst pipes.

Scheduling a Professional Plumbing Inspection

The best step you can take to prepare for winter is to schedule a professional plumbing inspection. An Eastern suburbs-qualified plumber can spot potential plumbing issues you might miss. They have specialised equipment to detect hidden leaks or vulnerable pipes and provide expert advice on winterising your system.
