The image below is our water bay ( compartment if you will ) This compartment door will NOT close when hooked up at a campground. There are three issues with it.
Issue one:
In the image below I've placed a 90 degree elbow on the black tank flush inlet. Without the elbow the hose would stick straight out not allowing the door to close. In addition to the elbow I've also added an anti siphon valve so fluids from the black tank cannot enter the hose itself. Moreover, the multi position switch (background center left) is labeled so poorly that I had to use my label maker to mark the positions more clearly i.e. Tank, City, Normal etc.
