Hey guys, take this from some who owns a pressure tester and did this for a living. All you need is 5psi to 10psi and the leak will appear...you never want to exceed cap pressure, no need to get even close. You guys are over beating this dead horse. This is a very simple-simple procedure.

I wish I didn't keep getting updated emails on this post.
