Schematics for Sandpiper 355RE Black Tank?

[rainsmik]

Does anyone have, or can direct me to a schematic of how the black tank is plumbed in my 2015 SP 355RE? Since my trailer is parked at the coast it remains stationary most of the time but used frequently, I remain paranoid about how well my black tank is emptying. So I am wondering where the toilet is located in relation to the final drain? Does the black flush push the waste toward the drain or just add water to the tank? Is there some additional flushing I need to be doing on a regular basis?.

My guess is that this is answered somewhere on the forum but for the life of me I could not find it.

Thanks.

Generally speaking, schematics either don't exist or aren't released to the general public.
