Picking up our first trailer next month and doing the rounds on youtube on how to empty you black tank. Question for you guys: Are you allowed to rinse the tank after emptying when you are at the station or is that frowned upon?
If they have a non potable water hose with a hose fitting on the end that's not been run over........I hook that up to the sani-flush while the black tank is draining. I turn it on soon as it hooked up so it gets a start on the rinse. Then when the black appears to be draining just flush water, I close the black valve, I open the gray water. When the gray is done, I close it and open the black tank to dump the flush water. This usually doesn't hold anyone up. But usually the non potable water hose either has no end or it's been run over.
