The bilge is not intended to have pressure, so it is not a good test. You can actually damage the boat this way.
Thanks a lot, Matt, for your quick response and your support. Looking forward to hear the technicians' answer! I know that there are a lot of posts in this forum and that it's not quite easy to keep a look at all... Therefor, I really appreciate what your are doing here for this community and want to say especially 'thank you' for that!
Regarding the qote above, may I quote the answer you gave me in another post...

I would use a small amount of pressure into the forward drain hole to slightly pressurize the bilge area. Use soapy water to see where air escapes. That is far easier and safer. Yes, you could have a leak between the pieces that is not a pressurized chamber leak."
The dealer only 'slightly pressurized'.....
