Question Black water flush line check valve stuck.

On my '12 Georgetown 337DS when water is supplied to my black water flush system I get a large leak at the supply line fitting connecting to what I believe is a clear check valve containing a spring and float assembly. This is a new problem so I believe the valve has become faulty. It is located under the bathroom sink with easy access. Can anyone help with the real name of this part and can it be it be cleaned/lubricated/returned to normal service? Anyone else have this problem? Thanks

You can also delete it and just add an anti siphon to the end of the hose at the flush fitting. Many have done this.
