Leaky waste tank

[Don Bradner]

Now you are going to make me second guess myself! Actually, I think that is
pretty remote, for a few reasons. First is that the leak began when there was
far less fluid in the tank than the top of the valve. Second is that I was
checking the valve and drain extremely closely (using an extension mirror to see
the back and bottom) as I was filling, when everything was dry, because I
considered it a prime area. I wasn't actually thinking about the valve itself,
but rather the connections. All of that valve and pipe stayed dry even when the
base below the valve eventually became wet as it spread.

Yesterday while I was getting everything dried out I did pull the valve and
grease it as a routine maintenance item - it looks fine, although it is getting
stiff and probably needs replacing at some point soon.
