But I avoid full hookup sites whenever I can. I keep my crap to myself, until I get to the crap station to unload it. I wish everyone did. Those sewer hookups are notorious for leaking and I have seen so many full hookup sites with lots of nastiness around the sewer connection that I never use one (unless maybe staying a month in one place which I never do). Not to even mention the people who have the full hookup and leave the gate valve open all the time.. yuck.
Actually the black water tank valve should not be opened except momentarily to empty it. There is no harm in using the sewer hose for gray water. Having had the hose hooked up to the gray water should be proof enough of its integrity.
I have a threaded elbow for a secure attachment at the sewer, yet many places require me to compromise that seal in favor of a "rubber donut".
I have seldom seen sewer hookups at state parks, they mostly use a dumpstation as you like..... But then there are those "blueboy" tanks!
The thread is about traveling with dogs though, which are generally allowed to crap on the ground most anywhere as long as the owner picks it up. I'm guessing that whoever made the particular rules above have a bit of an anal retentive personality!
( in a clinical sense of course)
