The current cold weather in Finland is leading to numerous issues with frozen pipes in homes, as noted by Andreas Norrgård, a foreman from the plumbing company Vaasarör. The frequency of calls for plumbing repairs has surged, especially in older houses, where infrastructure is more vulnerable to low temperatures. Norrgård explains that even newer homes can face problems if indoor temperatures are set too low for energy-saving purposes. Different types of pipes react variably to freezing conditions; for example, once frozen, copper pipes are prone to leaking while PVC pipes tend to be more resilient due to their flexibility.

The article highlights the various materials used in plumbing and their resistance to freezing. Old cast iron pipes can easily crack when frozen, while the safest option in cold weather is to use a protective sleeve around plastic pipes. This ensures that if the pipe does start to leak, the water will flow out from the sleeve instead of being concealed within the structural elements of the house, which can lead to more serious damage. Norrgård advises homeowners on the appropriate methods for dealing with frozen pipes, stating that a vapor device can be used to thaw a frozen copper pipe safely.

Moreover, the piece provides caution against using gas blowers to thaw pipes, as this could pose a significant risk. Instead, simpler methods like using a vacuum cleaner to create a gentle airflow may be safer and more effective. The need for awareness around pipe maintenance during extreme cold spells is a crucial take-home message, as homeowners are reminded to monitor their indoor temperatures to prevent costly repairs and ensure the longevity of their plumbing systems.
