Reading the responses, I'll state my opinion.
NEVER mix potable water items with any grey or black water items.
I bag my potable water hoses and fittings in a sanitary bag, and I use zip-locs to hold smaller items such as the fresh tank fill adapter. I keep hose ends connected to prevent any critters or dirt from entering the hose end. I use quick connects on all fittings, so it's easy to keep things tidy.
I carry "Clorox Cleanup" spay cleaner to sanitize all fittings...including the hydrant...every time I connect. Let it sit for about 15 minutes while performing other tasks, then turn on the supply and flush out the lines until the "cleaner" is removed. I also spray a bit on the city water fitting and/or the fresh tank fill port and rinse them before connecting. Then, and only then, connect.
I have a 25' "dirty" hose for use with my grey and black tank flushes and draining. (My grey tank has a separate 1 1/2" outlet.)
Yes, dogs pee wherever, including on RV park hydrants. Thus the Clorox Cleanup. I even spray it up into the spigot. My confidence in sanitation begins on the pressure side of the shut-off valve.
Two hoses are a cheap investment. The sanitation routine takes only a few seconds with a pump sprayer.
As for the morons who drape stinky slinky hoses over picnic tables, that behavior borders on criminal. But I would never use a picnic table for eating without cleaning it first. Bird crap is enough motivation for that.
To each his/her own I guess, but given the fact that e coli can cause life-altering or ending illnesses, I'll continue to employ basic sanitation techniques and keep my family safe.
