Removing the valve is an option. But you need to use an external back flow prevention valve if you do to prevent the unlikely, but possible, backflow of water into the fresh water source.
Thanks for the reply. I thought this hose goes only to the black water tank. How is it possible to get into the fresh water source? Figured it was a connection to a hose with a check valve as a safety feature in the event you forget to open the black water drain valve that goes directly to the black tank.

DO you use a water pressure regulator for city water hose AND black tank flush hose????
Yes...backflow preventer under sink leak. Some because they get cracked from freezing temps, some from high pressure being used (they have an air gap) that is how they break vacuum.
