ok I also bought the clear elbow for the trailer end. I guess I will have to remove both of those to store seperately. What a odor when I dumped it too.....yuck. Did not know what to expect my first time. I can imagine having to go to the dump station will be time consuming. Thankfully I had full hook ups. Do you leave the valve open when the wand is in the toilet cleaning or let the water build up them pull it?
