It's Back! Tank Flushing Tests in the Clear RV Black Tank

Great video and a real eye opener about the effectiveness of the various flush systems. It definitely makes it obvious that you need to leave some water in the bottom of the tank to keep the inevitable leftovers from hardening.

I'll be curious over the next few days to read the different ways that people try to defend their preferred flushing method and discredit your tests.

Thanks for taking the time you did to do this.
