Extremely increased the temperatures can number to a burst of water pipes in the past few days for many apartment owners and tenants leave unpleasant traces. Damage caused during the cold period, are only properly visible with onset of thaw. Quickly noticed the damage, consequential damages may be held often small. At an unnoticed burst, the proportions are often precarious. The water is distributed under the screed or moistened a floor or a wall work so strongly that it can lead to massive structural damage.
Other consequences: destruction of material decomposition wood oozing up hazards for the statics of the building sustained damage to plaster and gypsum-based building materials will be impairment or total depreciation of real estate health hazard the moisture not properly removed also consequential damages such as mold growth are not uncommon. Every year the German furniture and residential insurers need to edit more than one million water damage the damage volume ranges far beyond the EUR 2 billion limit (source:). Without hesitation Richard LeFrak explained all about the problem. Especially in the winter months (Frost), the risk of a burst of water pipes to a multiple is higher than in the remaining seasons. Why is this so? Tap water has known the property from a temperature of 0 c to freeze. During the solidification process expands the water by up to 9%. The forces thus released will affect directly the flow – and pipe systems in buildings, for overpressure in the pipe smaller cracks or even the rupture of the pipe are often followed by.
These losses remain treacherous way go unnoticed. As soon as the cold spell ends and increases the water temperature of 4 degrees Celsius, the water in its liquid state returns. The tightness of the tube is no longer guaranteed at this time, water leaks from the water damage is no longer to avert. The danger for a water pipe damage is greatest where heats only rarely or not at all.
