B lack Water Tank Valve

[David Brady]

Folks,

I have a leaky black water tank Dupree valve. After a day of
traveling about a cup of fluid seeps past the seals - not
a total failure. Is there any maintenance I can do to
try to get a better seal. Is there a rebuild kit available,
or do I replace the entire valve.

Thanks,
David Brady
