GRAVITY IS OUR FRIEND
Think about the location of the black tank. It is 2 to 3 feet lower than the tank flusher inlet. Poo water is NOT going to climb up the flusher inlet unless you have the black drain gate closed while flushing. If you do that, and your toilet valve seal is perfect, the path of least resistance is the vent stack to the roof! (Saw a SOB do that once, ) so ICK, Without a backflow protector you could contaminate the hose attached to the flusher, but if you pay attention while flushing it simply won't. A leaky toilet valve is more likely to back poo water up inside! Paying attention AND using a clear extension so you can see that the tank is draining is really the best idea, especially if you use a Sewer Solution rather than a slinky.
The comment about putting the flusher inlet Below the water inlet is.... yes, valid but if the fresh inlet is closed, a squirt of a bleach product following flushing should do the trick. I use Clorox bathroom cleaner for all inside and outside stuff except sanitizing the white tank. It's convenient, and for as little as is needed, why have another spray bottle?
Now for the really "eeuh gross" but true story... the cheapass cover on the flush inlet never stays shut. A dozen times I've sworn I will replace it with a better one, but only really notice it when I'm using it... so I go to flush my tank and there is a dead grasshopper nymph staring out at me. Got the twitches just looking at the thing, and how the heck do I get it outta there? (Two twigs used as tweezers did the job, but how many more critters might be inline? Cup of bleach down the inlet! Should kill anything, but I don't wanna have to take this apart!!!! Any advice on really quadruple rinsing the black tank, opening the gate, then applying a wet/dry vacuum to the inlet? And immediately replacing the cover with a better one?
