Sewer Hose Storage

I store my hose for dumping at dump station in the bumper. I use to store my sewer hose and connections in its original box in storage bay. I almost never stayed in sites with sewer. Now I find myself staying more in places with sewer. I was camping next to a guy that had a spray bottle sitting out after he had set up. I asked him what the bottle was for and he told me it was his bleach spray. He always sprayed the hose bib before hooking up his water hose to it. He said some people use the bib to rinse out their sewer hose. Yuk.
