9 Common Winter Plumbing Problems and How to Fix Them
As temperatures drop across the UK, winter brings a fresh set of challenges for your home’s plumbing. Cold weather puts your pipes, boiler and drains under more stress than usual. Small issues can escalate into costly repairs if not dealt with early.
To help you stay warm, safe and prepared this winter, we’ve put together the 9 most common winter plumbing problems and how to fix them.
1. What happens when pipes freeze?
Frozen pipes are one of the most common and damaging winter plumbing problems. When water freezes, it expands, restricting flow and increasing the risk of burst pipes.
Key signs:
- No or reduced water flow
- Gurgling sounds
- Frost on visible pipework
How to fix:
Turn off the water supply, locate the frozen section and gently warm the pipe using a hot water bottle or warm towels. Never use a flame or boiling water, as this can cause pipes to burst.
2. What to Do When a Pipe Bursts in Winter
When pipes crack due to frozen water expanding, they can burst once the water begins to thaw. This can cause significant water damage and lead to costly repairs.
How to fix:
Turn off your stopcock immediately and try to contain the leaks using buckets or towels. Look out for any rooms that have bulging ceilings, as these pose the threat of collapsing ceilings. Call a plumber as soon as possible.
3. Why Your Boiler Breaks Down in Cold Weather (And How to Prevent It)
When signs of winter begin to show and the cold creeps in, you may turn straight to your boiler and heating system. However, after months of summer neglect, the harsh conditions and workload can often lead to breakdowns.
Common signs:
- No heating or hot water
- Strange noises
- Water pressure repeatedly dropping
How to fix:
To keep your boiler performing optimally and to the expected standard, it’s recommended to get an annual boiler service. This should be completed by a Gas Safe engineer and will allow you to spot any early signs of a boiler breakdown.
4. How to Fix Low Water Pressure in Winter
Cold weather can often impact the water pressure of your taps, showers and baths. This is especially common if pipes are partially frozen or blocked, as the water cannot flow freely.
How to fix:
Check for frozen outside pipes, make sure there are no blockages of your taps or shower heads and ensure valves are fully open. If the pressure is still low, the issue may be internal. For more information, take a look at our latest article on the causes of low water pressure.
5. Clearing Blocked Drains During Winter Months
Heavy winter rainfall, fallen leaves and food residue from those weekly roast dinners can lead to slow-draining sinks, showers and blocked outdoor drains. As blockages occur, they often escalate and snowball if not treated.
How to fix:
Remove visible debris, flush toilets with hot water and vinegar or use a plunger. If your outdoor drains are overflowing, it’s best to call a professional to take a look.
6. Radiators Not Heating Properly
With radiators being integral to your home’s heating, it’s important for them to be working effectively. Cold spots, noisy radiators or poor warmth distribution are typically caused by trapped air.
How to fix:
The first step is to bleed your radiators to release any trapped air. This will allow the heated water to flow freely within your radiators, heating the entire shell and keeping your house toasty.
7. How to Stop Taps and Valves Leaking in Cold Weather
Cold temperatures can harden rubber washers and weaken joints, causing leaks in your taps and valves. Persistent leaks can lead to structural damage, so spotting the signs early is vitally important.
How to fix:
Try to tighten the fittings where you can or replace the worn washers. If the leak continues, it may require a full valve replacement. To ensure these are fitted correctly and secured, it’s best to consult an expert plumber.
8. Faulty Water Heater/Cylinder Problems
Whether it’s a warm bath or extra water for the washing up, the demand for hot water tends to increase during winter. This extra demand can expose faults in unvented cylinders, water heaters or thermal stores. The last thing you want on a freezing, dark winter morning is to be caught out by a cold shower! Even if they are apparently good for you…
How to fix:
Check thermostat settings, listen for unusual noises and ensure your boiler is working correctly. If your hot water system is outdated, consider upgrading to a pressurised hot water cylinder.
9. How to Protect Outside Taps from Freezing
By being exposed to fluctuating temperatures and extreme weather conditions, outdoor taps freeze easily. If not protected or fitted correctly, this can lead to internal pipe damage and long-term issues.
How to fix:
Insulate your outside tap or fit a proper cover. If frozen, thaw gently using a warm towel and check the pipework behind the wall for leaks.
