What are the most common causes of water damage?

  • 1. Installation and mounting errors

    Almost 40% of all pipe water damage is due to execution errors in the installation of pipelines or mounting of devices in the piping system. This is one reason why not only old buildings are affected by water damage. Damage can occur frequently, especially in the first few years after new construction or renovation.
  • 2. Operating conditions

    Pipelines and water-carrying devices are exposed to very different operating conditions throughout their lifetime, which can sooner or later lead to water damage. Overall, more than a quarter of all water damage is due to material fatigue or corrosion caused by "challenging" operating conditions.
  • 3. Product defects

    In 11% of all cases, the reason for water damage is the use of defective or low-quality pipes or other components of the piping system. Therefore, the saying applies to pipe installations as well: buy cheap, buy twice. But there is a big difference. Before you buy a second time, you must renovate your home first.
  • 4. Planning errors

    Good planning and properly executed installations are basic prerequisites for trouble-free operation and a long service life. Although only 1% of all water damage is due to planning errors, especially in times of a construction boom, full order books and corresponding time pressure can lead to mistakes in planning.
  • 5. Further causes

    In addition to the causes already mentioned, there are of course many other reasons that can lead to water damage. Be it deposits that clog the pipe, "drilling accidents" when hanging a wall shelf or mechanical stress on pipes or connections.
