I think you mean Air Admittance Valves (AAVs) that allow air into the sink drains but keep odors out. Generally they are underneath any sink when it's not practical to vent out the roof. Anti Siphon Valves are used in the black tank flush system to prevent backflow.

Yes I was reading the Post ... Black Tank Flush [just below mine] and he is talking about the valve that allowed water to enter his coach .. i was wondering if they are the same and where those valves are located.
Yes, the anti-siphon valve is under the bath sink. Look for a black widget under the sink just below the counter. Mine is blue PEX pipe coming from the floor to the anti-siphon and then another blue PEX pipe going back into the floor of the cabinet.
