We recently bought a 1967 Caravel
that we are looking forward to restoring for my hubby's retirement project. Problem is.... we cannot figure out how to dump the black water tank so are very hesitant to use the toilet. We put water and chemical in the tank but cannot figure out how to let it out and rinse it. See the coupling and the line, but what opens the valve. The manual says "open the gate valve to drain", but where the heck is the gate valve??
There is nothing under the trailer near the hookup and we can't see anything in the bathroom.
Thanks for any help.
