Backflow Prevention
The European standard EN 1717 regulates the "protection against pollution of potable water installations and general requirements of devices to prevent pollution by backflow". It was published in May 2001. Basically, a protection level of higher quality than the prescriptions in EN 1717 can be applied without infringing the recognised technical rules. The European Standard EN 1717 works with five risk categories, which are designated as fluid categories.
