sani flush black water holding tank
Our motorhome has a saniflush for the black water holding tank. Do you think using the fresh water hose on the saniflush would be safe as there is probably a backflow device on the saniflush?

rv dealers have a grey hose used for the flushing of black tanks. they come in various lengths. I sure wouldn't take the chance of using my fresh water hose to hook up to a black tank with or without a back flow device.
