You can take it off and throw it away then connect the pipes together with a one way flow brass fitting brass fitting then put the back flow anti siphon fitting on the hose outlet in the conveyance center and this wont do any damage if it leaks, this is how I dealt with it.

Replace original plastic fitting with the stronger brass anti siphon valve but still risk the leak or potential flood in the camper

Although a code requirement in some states/counties especially with well systems my plumber says a backflow condition to the public water supply would be extremely rare and never heard of it happening in his 39 year career.

Or just cap the pipes off altogether under the sink with Shark Bites caps. Do you think that little nozzle in the tank really dose anything to clean out the tank any more than adding more water to the tank and dumping again which is what you should be doing anyway.
