Discover how to protect your drains in winter with expert tips on clearing debris, insulating pipes, and preventing freezing. Keep your drainage system reliable year-round.
Clear Leaves and Debris Before Cold Weather Hits
Before temperatures drop, it’s important to remove leaves, twigs and other debris from around your drains. Blocked drains can stop water from flowing properly, which leads to standing water that can freeze.
When water freezes in or around your drains, it can cause cracks or damage to the pipes. Use a rake or brush to regularly clear garden areas, especially in autumn when leaves fall more often.
Make sure you dispose of waste properly, either through composting or garden waste bins. Taking this simple step early in the season can help avoid bigger problems later, saving time and money on costly repairs.
Insulate Outdoor Pipes and Drains
Outdoor pipes and exposed drainpipes are particularly vulnerable in winter. If temperatures fall below freezing, any water left inside can freeze, expand and crack the pipe.
This can lead to serious leaks or even flooding when it thaws. To avoid this, insulate your outdoor pipes using foam tubing or pipe wrap. These materials are easy to find at most DIY stores and simple to fit at home.
Focus on areas like outside taps, garden drains and pipes in unheated places such as garages or sheds. You can also cover outdoor drain openings with insulated lids or specially designed covers to help trap warmth and block out cold air.
If you're unsure about which insulation to use, speak to a local plumber for advice. It’s also wise to turn off outdoor taps that you won’t need in the colder months and drain them properly.
With the right insulation and preparation, you can keep your drains working smoothly and prevent winter damage.
Keep Gutters and Downpipes Clean
Blocked gutters and downpipes can lead to serious issues in winter. If rainwater can’t flow freely, it may collect and freeze, adding weight that can crack or damage your pipes. To prevent this, clean gutters and downpipes regularly—especially after heavy rain or strong winds. Remove leaves, moss and dirt by hand or with a scoop, and rinse with water to check the flow.
You can also install guards or covers to reduce future build-up. Regular cleaning helps keep water moving away from your property, which protects both your drains and your home’s foundation.
Let Water Run Gently During Freezes
When temperatures drop below freezing, it’s a good idea to let your indoor taps drip slowly. Running water is less likely to freeze, even if it’s just a small trickle. This gentle flow can stop pressure from building up in your pipes, which reduces the risk of burst drains or pipes. Focus on taps connected to pipes running through unheated areas, such as under the stairs or along outside walls.
If you’re planning to be away for more than a day during a cold snap, keep your heating on low and ask someone to check your property.
You can also open cupboard doors beneath sinks to let warm air reach hidden pipes. If you do notice slow water flow or odd sounds from your pipes, it could mean ice is forming.
In this case, turn off the water at the stop tap and call a plumber. Taking small actions like these can help prevent major water damage and costly repair bills.
Check for Leaks or Cracks Early
Before winter sets in, inspect your drains and pipes for early signs of damage. Small leaks or hairline cracks might not seem serious now, but freezing temperatures can make them much worse. Look for damp patches, water stains, or mould around pipe joints or drain openings. Check outdoor drains for damage or loose fittings.
If you spot any problems, it’s best to get them repaired straight away. You might be able to fix small issues with waterproof tape or sealant, but always seek professional help for larger faults. Acting early keeps your drains safe and working all winter long. 4o
