I know that sch 40 pvc is not allowed now but inspected a 12 year old home with this issue. Should I recommend replacement or what. What is the safety issue, if any.
thanks

Why do you say that schedule 40 pvc isn't allowed?

The original post did not say where or how the PVC was being used that's why I asked.
He stated in the title "used as cold water supply".
You can use schedule 40 PVC for water service pipe.

If you see this on the hot water side, its not rated for the temp, write it up
