When temperatures plummet in winter, pipes exposed to the cold run the risk of freezing, leading to burst pipes and costly damage. To avoid this, it’s essential to take certain precautions to protect your plumbing system from freezing.

Identifying risk areas

Not all pipes are exposed to the same level of risk. The most vulnerable pipes are those located :

• Outdoors, such as garden taps or sprinkler pipes.
• In unheated rooms, such as garages, cellars or attics.
• Near poorly insulated exterior walls.

A preliminary survey enables us to anticipate the protective measures we need to take before the cold sets in.

Insulate exposed pipes

Thermal insulation is the first preventive measure against freezing. We recommend wrapping sensitive pipes with :

• Foam insulation sheaths specially designed for plumbing.
• Bubble wrap or improvised insulating materials in case of emergency.

Shut-off valves and water meters located outdoors must also be protected with insulating enclosures to prevent damage.

Purge outdoor systems

Before winter sets in, it’s a good idea to cut off the supply to the outside pipes and drain them, to prevent water from stagnating and freezing inside the pipes. Outside taps should be left slightly open after draining to relieve any residual pressure.

Maintain minimum temperature

In areas where water pipes run, it’s important to maintain an ambient temperature above 5°C to prevent freezing. This can be ensured by :

• Auxiliary heating in uninsulated rooms.
• Open cupboard doors under sinks to let heat circulate around pipes.
• Let a thin stream of water run through sensitive pipes in very cold weather, to prevent ice formation.

Install heating cable for critical areas

For particularly exposed installations, an anti-freeze heating cable can be laid along at-risk pipes. It works by slightly heating the pipes to prevent freezing, making it an effective solution in cold regions.

What to do if a pipe freezes

If a pipe is frozen, never force water to flow. To thaw the pipe gradually :

• Gently warm the affected area with a hair dryer or hot towel.
• Never use a direct flame (flashlight, lighter), which could damage the hose.
• As soon as the ice begins to melt, open the taps to let the water out.

If the pipe cracks after thawing, it must be replaced quickly to avoid leaks.
