That inlet will only flush out the BLACK tank...I drain my BLACK tank all the way then hook up the flush and with the valve still open I let it run for a few minutes. At that point I close the valve for a minute or 2 and stand there (like already posted) to allow the black tank to fill up a bit. At this point I open the valve again and let it drain down ,after turning off the hose I allow a few minutes for all the water to drain , close the black valve and then open the GREY valve and let her rip ! This will flush out all the black tank stuff from the hose..And by the way , dont forget to winterize that inlet or you could have an issue in the spring ! Joe
