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

Great video!! I'd love it if you would make the "Geo method" (calgon and tide) be one of your test cases of additives. Although it works in conjunction with driving around.

I'm glad my rinse method is just using the third blade to backflush the grey into the black for 30 seconds twice after emptying the black. It's just a way to add fluid after emptying like you recommend. And never let the tank stay empty.
