[VAL] Blackwater tank dump valve and 'exhaust' fittings...

["Mark" <mark@xxxxxxxxxxxxx>]

Hello John, welcome aboard and congratulations on your step up to the top of
the travel trailer heap!

On my '62 Tradewind, there's a little handle just under the head area,
accessible from the outside, which needs to be unscrewed a few turns, then it
pulls out and dumps the blackwater.  When the tank is empty, you shove the
handle back in and tighten it back up again with a few clockwise twists.

My gray water runs right out the big pipe, unless I cap it off with the cap
such as you described...with the hose fitting.  I run that small hose into a
plastic tank to keep the gray water contained, when I have no place to connect
the big hose.

When you ARE connected to a sewer line, leave the dump valve CLOSED until you
want to dump the tank, then close it when you've finished emptying the tank,
or the valve will get clogged and stuck with dried up things too fierce to
mention, and it will drip and leak right where you don't want it
to...anywhere!

I believe the last time I bought a hose and fitting for mine, I had to buy the
'old style' onaccounta the standards changed to a smaller hose on the later
models.  One of these decades I'm going to re-plumb that 'exhaust' to bring it
up to date, butt for now, it works just like it did when God designed it.

If it ain't broke...

Hope that helped and I hope you love your new/old Airstream like the rest of
us do ours!
