In some regions, freezing temperatures are severe during the winter, so there is a risk of serious damage to outdoor faucets and pipes without a proper procedure before the cold weather arrives. Let's take a look at how to do it easily.
Why bleed your outdoor pipes?
During the dreary season, temperatures can very easily drop below zero and even reach extremes depending on the region (down to -20 or 30°C). The water in the pipes or faucets freezes and takes up more volume, sometimes causing them to burst. The equipment is therefore put to a severe test and, if it is already fragile, it can be damaged very quickly.
When should I bleed my outdoor pipes?
It is important to purge outdoor pipes as a preventive measure in the following cases
Regions with very harsh winters;
Prolonged absence that does not allow for quick intervention in case of a cold snap;
Pipes or ducts that are not or only slightly buried (a minimum depth of 70 cm ensures frost protection).
Please note: in regions where winters are mild and frost is rare, the procedure is not necessary, but it will be necessary to act in case of an exceptional climatic event, which implies to be present.
How do I purge the outside pipes?
Start by locating the water inlet valve, which is usually located upstream of the pipe. Turn the valve to shut off the water;
Open the taps to drain the remaining water from the pipes;
Turn on the small tap near the water valve to drain the pipes;
Once all the liquid has drained, close the drain valve and the valve again.
Remember to store the hoses in a dry, frost-free place to keep them in good condition during the winter.
If you live in an area where temperatures remain within a reasonable range, simple protection of the pipes and valves may be sufficient. Polyethylene foam insulation tubes are available to protect pipes. Bubble wrap in several layers may be sufficient for fittings.
Avoid newspaper or rockwool which tend to retain water and thus amplify the phenomenon.
