Yup, have one of those in my "water fix it" closet on camper. It will work in a pinch but harder to keep from freezing back down the water line, if we decide to refill or hook up instead of working out of water cans. Have wag bags for potty to super dry camp, just not fun for three weeks. Just been fixing here and there for so long would really like to be done for a while, but there's always maintenance even with a new camper. At least with old one you expect it to a certain degree. Kinda like us old folks, always need fixing.
