I built a clear Black Tank Simulator so I can see exactly what happens inside the RV black tank when you dump. In this review, I explain the black tank simulator, the simulated waste I used, and show you tests of a standard dump hose, and the Sewer Solution from Valterra. It's a bit of a longer video, but the results may surprise you!

If you'd like to comment, or have suggestions for my next experiment, leave them on our web site. There's also a bit more information there about this test: http://www.thefitrv.com/rvtips/insid...
