We. have a 2020 Navion 24V that uses a single 3-4" hose clamp as the only support for the entire ABS dump valve and macerator hose--no pipe or strap hangers connected to the frame at all. My Neoprene fitting is in good shape, but last August the ABS valve fell out of that Neoprene connection when I tried to unscrew the cap. The entire contents of a half-full black tank spilled all over the concrete pad of the dump station, as well as covered most of me from the waist down. Apparently the screw on the hose clamp had loosened on some of our Colorado mountain roads and was just waiting for a good twist to pull it completely out of the Neoprene. Needless to say, after cleaning up the mess, I immediately began looking for a pipe hanger at Home Depot and Lowe's. When I couldn't find one the right size, I made my own hanger using perforated steel pipe strap. The 1/2" wide strap perfectly fit a groove located directly behind the cap on the ABS dump valve assembly. We took a week-long, 1 ,000-mile trip two weeks later and had no more problems with the dump assembly.
I would strongly recommend that all View/Navion owners check their dump systems for correctly installed pipe hangers. If none exist, install one!
