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?
You would be surprised at how many people forget to turn off the water and accidentally leave the flush line running. This board alone has several such stories from people forgetting the flush or fill lines running.
Regardless, it doesn’t take much contamination for the process to start, merely vacuuming the little bit of contaminated water in the tip and then air from the enclosed space of the tank would be plenty.
Back in 2000 a small amount of E. Coli contaminated ground water made its way into a municipal well serving a small town near here. Even in the treated water of the towns water system it spread and multiplied to the point that 7 people died and 2,300 of the 5,000 people in town were very sick. If not for the Government allowing a drug in clinical trials to be given to the sick they figure at least 10 more children would have died also.
