As temperatures drop, your pipes can freeze.
Solutions exists : purge and isolate
An outdoor faucet is often exposed to the elements. From -5 degrees the water held by the tap can freeze and damage the pipes. Frozen water takes up more volume and can burst your pipes. Cracked pipes cause leaks and therefore flooding. This is why, before the winter period, you have to insulate your pipes.
It is important to know that:
> les canalisations avant le compteur d’eau sont du ressort de votre fournisseur. the pipes before the water meter are the responsibility of your supplier. The pipes after the water meter belong to you.
> your water supplier owns your water meter but it is your responsibility, whether you are the owner or the tenant.
The only solution to properly protect your water meter and your external pipes, or in unheated places (cellar, garage, crawl space) is to purge them before insulating them.
You are not immune to a cold snap affecting your facilities in your absence. You will understand, it’s up to you to take your precautions!
WARNING: most home insurance contracts provide for a reduction in compensation ceilings if you have not taken preventive measures to protect your installation.
The use of newspapers and glass wool to protect the pipes is prohibited because they retain moisture.
It cannot be repeated enough, quality materials and the right tools are essential to do serious work. The professionals are there to support you in your projects.
