After changing to the longer hose I noticed I wasn't feeling as well in the mornings. I have one of those pressure testing attachiments so I put it on the end of the 10 foot hose and turned my machine on. The meter said I was only getting a pressure of 8 instead of 11. I know the 6 foot hose gave me a pressure of 11 at the end as I had checked it. I accessed my machine and uped the pressure out of the machine to 14 and the meter read 11 at the end of the hose. Guess this proves that a longer hose will require adjustments to your machine. Hope this helps someone.
The S9 vpaps have a setting for the 3meter hoses, just have to select them and not worry about any other settings.
