That's what I thought. How are you going to ensure that you don't have a small leak somewhere on your apparatus that fools you in to believing you have a block leak when really you don't? Won't you have to at least spray down some parts of your connections in order to rule out a poor test procedure?

The test apparatus and all connections will be entirely visible and subject to viual scrutiny with the soap suds. I pressure test refrigerant systems in a similar fashion.
