I agree with fourth year. I see too many failures after the fact, find them first.
If you want, test the pex to its rated limits, if it fails, then it was defective. If you state that it should not be tested to its rated limits, then you are acknowledging that a problem with the product may exist and you just do not want to find it. I’d rather find it before the walls were closed up. The rated limits are not failure limits, they are safe maximum use limits.
