I don't share the list's disdain of flex tanks. Touche' has flex tanks for both potable water and waste water. No issues at all.
In fact, the potable water tank is easy to clean each spring. Just empty it, yank it out, put it on the dock, put some water in it and slosh it around. Rinse and reinstall. There have been numerous threads on rigid tank failures. Just saying. Dennis C. Touche' 35-1 #83 Mandeville, LA
