KEMPER PROTECT Backflow preventer BA
DIN EN 1717/DIN 1988-100
DIN EN 1717 stipulates a uniform standard for drinking water installations for protecting the drinking water against non-potable water throughout Europe. This standard differentiates the application areas for protection valves and defines the fluid categories. Along with the water supply companies, the technical consultants and plumbers are consequently increasingly faced with a liability risk. DIN 1988-100, in addition to the DIN EN 1717 national fundamentals, stipulates the protection of drinking water against fluids up to Category 5.
To accomplish that, KEMPER provides the safe, technically mature solution: The patented KEMPER PROTECT Backflow preventer BA protects drinking water from non-potable water up to and including Fluid Category 4.
According to DIN EN 1717 and DIN EN 806-5, there is a periodic maintenance obligation for the backflow preventer BA. Accordingly, a maintenance contract should be concluded for the annual maintenance between the operating organisation and the plumber.
