From a temperature of 0 ° Celsius, water freezes. This causes it to expand. If it is in a water pipe, it can be severely damaged. In spring at the latest, when you have to water your garden again, you may experience a nasty surprise. What options do you have to avoid this?

Winterproof water taps
As soon as the night temperatures slip into the basement and there is a risk of frost, the taps in the outdoor area must be made frost-proof. Even if the tap has not been used for a long time, there is always some water in it. This can freeze at the corresponding sub-zero temperatures. This can damage the pipes that run inside as well as the inside of the fittings. This can be very expensive because the water comes out of the burst pipes and can penetrate the masonry. This also damages plaster and insulation. To prevent this, you should completely empty and turn off the tap in good time. Parts that can be removed should also be dismantled and the seals coated with petroleum jelly so that they do not become brittle.

Alternative: the frost-proof tap

An alternative to this method is a frost-proof tap, such as that offered by Kull Design. This winter-proof variant can withstand a pressure of up to 16 bar because it is equipped with a volume compensator that is located in the frost-proof area. It ensures that the amount of water or ice is automatically balanced. Such faucets have another advantage because you can use them in winter. Valves with a shut-off valve are also available. This is connected to the tap by a long wave and keeps the water in the house. In the frost-prone area there is only air that is known not to freeze. In addition, such outdoor fittings are provided with a ventilation system that automatically drains the water-bearing areas.

You can easily retrofit the frost-proof outdoor taps, as they are possible for different wall thicknesses. The effort is worthwhile in any case, since it is significantly less than the renovation effort that would be necessary in the event of damage.

Frost protection for water pipes

In order to optimally water every spot in the garden and to ensure a lavish display of plants, amateur gardeners like to lay water pipes. This has the advantage that you don't have to worry about whether the garden hose is long enough. In addition, it is not ugly in the way in this way. However, when laying it, you have to consider that the cables should be protected for the winter. If there is frost, the water that is still in the pipes can freeze and damage them because it has expanded. Therefore, install a shut-off valve and a connecting tap when laying the lines. You can then connect a compressor to the tap using a hose. Due to the inflowing air, the residual water is displaced from the pipes and can escape from the external valves. Use PE pipes for this, because they are corrosion-free and there can be no deposits.

Pay attention to the correct depth

A certain depth also protects against frost. House connections are therefore buried from a depth of one meter. If a good layer of sand envelops them, this also serves as frost protection. Garden water pipes do not necessarily have to be laid so deep when they are not used in winter. It is sufficient if you empty and switch it off like the external water tap. You can find detailed instructions on how the laying works here.
