I use a short 5 ft hose with a back flow preventer and a quick connecter. I have a spray nozzle with quick connect, and a quick connect on my tank flush. I hook the hose to the hose bib in the compartment then snap on to the flush qc. Turn it on dump black, if the gravity is not right I will lift the hose and drain it before I dump the gray. I let the flush run for 10 minutes +/- after I lift the hose again if needed. I then close both valves and let the flusher fill the black tank with 5 to 10 gallons of water. Disconnect from the flusher, connect the spray nozzel, final rinse and done. I never leave my slinky hooked up nor my grey valve open.
