As it turned out, the whole thing was moot, because the price for the pump alone (plus a handle and the straight adapter) was MORE than purchasing the ENTIRE toilet, bowl and all. Seems Raritan lowered (!) it's price for the complete PHC toilet by $60 over last year's Defender price. I guess they're trying to beat out the competition for people outfitting a boat, but not those who want to repair/improve it. Let's face it, merchandise is a mystery to me.

thanks all.
