I am doing a frame off restoration of a 1963
Bambi. ( above the frame black water tank, and no grey water tank)
Getting ready to insulate the floor, and put the belly pan on. And want to make sure I have a plan for the sewer system, before I get to far into buttoning up the floor
I need to check the old belly pan, but I think there is an access panel so I can get at it later if I need to, but it is easier to work on with the frame flipped over now. The dump valve I took out is a thetford model 10447, but I understand many models had that designation
How do I assess the dump valve to see if it is worth putting back in? Not sure if it is the original 1963
, or if it has already been replaced during it's life time. When they fail, is there a common problem? What do I look at to see if I may was well just bit the bullet and buy new?
