Peggie:

I have a follow up comment/question - the tank's 3/4" vent hose on our boat
goes from the top of of the holding tank through the side of the boat above
the deck. It terminates in a small chrome "mushroom" with two small holes. I
cannot figure out how to get a good backflush going through the small
openings... is there some kind of tool or adapter available for this purpose
or what am I missing???
Claus

P.S.
After emptying, rinsing etc. of the tank and applying a dose of Oderlos
(what a bizarre moniker, unless you are norwegian) the odor is gone - hope
it lasts until the next pump-out!

If it were my boat, I'd replace the thru-hull with an open bulkhead
fitting and--if heeling puts it under water--clamshell over it.

Odorlos IS a Norwegian import.

If you expect to without adding more, you didn't read ALL the
directions....'cuz it won't. Odorlos isn't a live bacteria product that
contines to renew itself by multiplying...the active ingredient in it is
nitrates, which exhaust themselves in about a week, So to keep it
working, more must be added. It's especially important after the boat
sits for several days--even if you pumped out and added it last thing
before leaving the boat, that you add again with the first flush when
you come aboard.

Peggie, when I search of an "open bulkhead fitting" on WestMarine
website, nothing shows up. I too have the fitting with two small
holes on the hull of my Pearson. it is heavily corroded so i assume it
is the source of the most foul smell I hav when pumping my new Lavac.
Can you be more descriptive of what this fitting it?

thanks

Come on, Ed...surely you have more imagination than that (I hope!)! It
never occurred to you to try just "bulkhead fitting?" Or, since you're
looking for a type of thru-hull, "through hull"... or "thru hull?" WM
was the only site you searched...you didn't try any other marine
retailers?

I guarantee you'll find plenty of 'em if you put a bit more thought into
your search. I just found a zillion of 'em in all sizes and materials on
the Defender site http://www.defender.com. And a google search turned up
a zillion more on non-marine sites.

Nylon is ok for the new fitting on the tank, but go with stainless or
bronze for the thru-hull. As for what size you need, I'm not sure
whether the nominal size for fittings is the OD or ID, so you'll need to
ask to make sure you get the right size to fit into a 1" hose.
