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???

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!
