Wirsbo aquapex?

I inspected a house today with WIRSBO AQUAPEX clear water supply. The connectors are brace. I did not see any deficiencies. See attached pics;

Are there any known ongoing problems. Should I recommend further evaluation by a plumber?

There was a class action suit in regards to the brass Wirsbo connectors that were at least 30% zinc. I just did a replumb with Wirsbo PEX and used all new brass connectors that do not have that issue. It was mostly the connector, not the PEX although some arguments were made it was the combination. Recommend further evaluation by a licensed plumber that is qualified for this identification and class action.
