Sorry, Cheyanne, I didn't mean to suggest I left it open to the ground...I
am hooked up to a sewer connection. And as I understand it, in that

valve closed. (graywater open for general convenience and free use of water,
blackwater closed to avoid the nasty situation described earlier in this
thread.)
