Thoughts on how to report on Pex/Kitec plumbing?

I would love to know the specifics of how others are dealing with Pex/Kitec plumbing.

As I understand it, there are seperate issues with supply line failure and specific fittings.

Am I to identify the particular fitting and is there a list of exactly which ones are the problem?
How can I assume that the whole house utilizes that one type of fitting?
Am I to identify the particular tubing and is there a list of exactly which ones are the problem?
Do any of you know where online I can find a definitive breakdown?

This product is in almost every house I inspect and yet I have not come across any visible problems.

How are you writing this up for the report?

Thanks for your help
