These "fancy clear PVC" check valves, have no metal or spring inside. It works on a rubber flaps that seals shut in the event of back flow. They do affect head pressure slightly.
To each their own I guess. I'm sure if they had failed on me in the past like Tony has experienced, I'd be un-easy to use them as well. But I've got a perfect history with them so I can only advocate them.
