The anti siphon valve should only leak, if it leaks, while you are running the black tank flush. It should be located at the highest place in that pipe run. And is only pressurized when flushing. When not flushing, it has an atmospheric vent to relieve any pressure in the line and drain the water into the tank. Is it a continuous drip even when not flushing?
