I have a black water dump valve that leads. When I take off the cap to the gray
and black out let there is fluid which has leaked past the guillotine valve. Does anyone
have experience in replacing the valve.

     It looks to me like I will have to remove the sheet metal covering for the gray &
black tanks to get to the valve. Is there any other way?

Will it heal it self if let be? It hadn't been used for about a year when we bought it.

Thanks for any input you might have.
