I just finished the assembly of my new setup and I am having an issue with my new ball valves (2- and 3-Piece full bore ball valves).
Fresh water flowing through the valves (Kettle & pump outlets) will exit them with a strange oil/plastic smell. The water still tastes normal, but the smell is well noticeable.
I rinsed the valves many times with cold water, hot water, oxy-clean and even sanitizer, without recognisable improvement.
Is there anyone with a good idea, how to solve the problem? How to properly clean the valves?
