You mean there is no possible way to contaminate the potable water hooking up a hose to my black tank and the potable water spigot?
No. How's that going to happen? It's not like black water somehow climbs up the tube and swims upstream to the faucet.
Actually, it can happen. If there were no one-way valve on the connection, the water flow back at the spigot to the fresh water tank could create a vacuum and siphon the water from he black tank (if it was full) back into the fresh water valve. That is exactly why the mfg'ers put the one-way valve on there.
I also use a "Y" at the spigot and use two hoses. White for fresh water tank, green for black water tank. However, I put quick disconnects on the ends of my hoses and in addition to turning off the water at the "Y" to the black tank, I will also remove the hose from the "Y". I once forgot to turn the water off and had a huge mess to clean up. :E
