After having the interior replumbed professionally, we discovered a major problem on our first trip out in Sassy. The drain pipe from the holding tank leaked horribly. Well, they don't make 2 1/2" PVC any longer so we tried bridging the leaking gap with (believe it or not) a plastic Creamora jar with the ends cut off. Actually, it worked----for one trip----and then the plastic was too flimsy to stand up to the task. Then, we found that the cylinder part of a Pampered Chef Measure-All would fit. We used it and about a ton of Gorilla Glue and solved the leaking problem. Out we went again only to now discover that the drain valve (don't know the official name) doesn't work. Ask me how messy dumping was!!!!!!!!!!!!! So, now we've by-passed all of that altogether by connecting a drain hose to Sassy and to a Blue Tote. Worked like a charm.
Necessity IS the mother of invention!
Oh, did I tell you how much we love our '65 Shasta Continental??
