According to the EU directives EN 60335-2-79:2010 currently in force, the water that passes through a high pressure cleaner is no
longer considered fit for drinking. This is why such a cleaner cannot be connected directly to the drinking water supply network
unless a back flow preventer disconnector has been fitted.
