On-ground Pressurization Test
I've read several it is possible to hook a blower up to pressurize the cabin on the ground to look for leaks. I'm only getting about 1.5-1.7 psi on my 1973 P337.
Can someone tell me how to use the blower to pressurize on the ground so I can locate the leaks? It does not look like there is any ground sensing dump valve (squat switch that dumps pressure on landing), so maybe it is as simple as putting the blower at the right place?
Not expecting a perfect pressurization, but would like to be able to get more benefit from the system.
