This system has copper fittings and is **only **used with well water which has a water softener. It only goes to the exterior hose bibs, shop, and drinking water for kitchen. City water supplies the rest of the home in copper pipes. (No Cross-over) Will the PB tubing survive here or should it “always” be recommended for replacement? The owner and buyers should be made aware of its presence at the least.

It my understanding that chlorine and fluoride are the suspect culprits causing the deterioration of the PB. Since this system is not exposed to that, deterioration should not be a major concern. It is always wise and prudent to disclose that there have been issues and educate the client to the point where they can make a good/bad decision. If you make it for them you assume the liability for that decision.

There is still disagreement among many people, including plumbers. Here’s what I use (note that plumbers are licensed in the State of California, and home inspectors are not, which fact is the underlying cause for my specific recommendation).

I used what Russel wrote above and recommended replacement of the tubing as Joseph suggested. I also gave the clients links to 3 websites that discuss this. And I contacted Vanguard, the vendor. They confirmed PB (of course =D>) and gave me the information about the lawsuit. The client will receive that too.
Thank you to everyone for your direction!
