It usually goes up to a location under the sink, or behind the shower etc. It connects to a air gap antisiphon valve. The output from this valve now heads down to the tank sprayer. It shouldn't leak much when shut off, as gravity will make the clean side drain down thru the hose connection outside the TT. Maybe a drop or two.
your flusher system is somehow connected to the sink inside the RV? a very strange hookup. and the antiflow valve will leak when shut off as a little water will drain back from the "clean" side.
and if you want to blast at the pile of stuff, do not build up a bunch of water in there when you try that. all that extra water will do is absorb some of the hydraulic shock that the sprayer is trying to give the stuff.
since you bought the RV last fall and only now are using the sprayer for the first time, it may be impossible to get that pyramid out without heroic measures. as a last resort you could use a pressure washer either down thru the toilet if possible or remove the black tank sprayer and poke it in that hole.
and the salesmans statement I guess I will get the toilet wand and the Johnny Chock (Thanks to the poster who put that up! I would not have thought of it.) and be prepared to use that since this installed flusher is not good for this situation, in spite the sales guys promises that "You'll never need anything else!" would probably be true if you would routinely use that sprayer, not once a year after it becomes too late.
