Thanks for any advice you can offer.

Mine worked satisfactorily for several years, actually, about 10 years, then it started with the "whine" you described, like a pinched hose. During that period, the length of time it took for a complete filling of the tank increased several fold. More recently, absolutely no sound at all, not even the whine. I opened up the compartment underneath, inspected the short piece of hose visible after the fitting, and noted nothing unusual. I did a 24-hour soak, with my usual chemical, nothing exotic, then did a flush with an external attachment and with a wand down the throat of the toilet. I suppose the tank is reasonably clean, but internal flush mechanism is still not operational...silence. There's either some serious residue plugging it inside the tank, or some other in-line obstruction. I haven't checked the anti-siphon (I will next time, but we don't store at home), but I've seen no evidence of water where it shoudn't be, either inside the coach, or under the belly. Hmmm. I'll be watching for your solution.
