Sorry for the side ways pic. The flat cap should be on top with white water lines running down.
Thanks

It's the anti siphon backflo preventer valve on the black tank flush line. Yes they can go bad, they can be installed backwards not allowing flow to the black tank & are prone to leak from loose fittings.
You can replace it with a much better quality brass valve found at most hardware stores, just be sure to correct flow before installing or remove it & add a couple 90 degree elbows .
