I'm from Brazil and as I don't have a service center here, I do all the maintenance on my housings.
I've already service a AD90, AD5DMKIII and now I'm servicing a AD7100.
After replacing everything, I tried to apply the vacuum leaking test. And the housing is not holding the pressure. After getting a little desperate, I tried to sound check to figure out where the leak was.
I got some leaking sound from the OK back button on the housing. I tried to check the springs size, the button size comparing with the others in the housing, and as everything is the same size, I don't have any idea how to solve this.
Next week I'm going on vacation to photograph and would take the housing with me.
I have an option to test the housing on a 4 meters depth swimming pool. Do you think that I should try it? Is there any way that the pressure helps to accommodate the button to seal?

Any help would be appreciated. If you work on a service center, let me know, I can pay for some consultancy if affordable.
Thank you very much
