I'm still waiting to hear how, in the real world, and not some theoretical world in a different universe or the comedy world of the movie "RV", fecal laced water can be vacuumed back through the black tank line into the local water system, if the spray head inside the black tank is not submerged in said fecal laced water. Especially when said black water tank is 39 gallons large.
Is most everyone saying the vacuum created inside the black tank is so great it can pull water from the bottom of the tank through the air inside the tank and into the water hose, and hence to the local water system?
All it takes is for someone to forget they a flushing their tanks with a Flush King or flush tank with discharge valve and you create a plausible scenario. It happens plenty of threads on this forum alone where it happens. Now consider when it does contamination could occur.
