I have a 1980 Catalina 30
. I assume yours is like mine.
The tank is plumbed to the deck
fitting from the bottom rear of the tank (easy to get to under the port settee). Mine then runs behind/under the stove and icebox
to go to the deck fitting through the sail locker. If it's collapsed behind the icebox
, that's a very bad thing as it's very hard to get to.
As already mentioned, the vent goes to a stanchion on the port side unless it's been changed. Also I 'unlock' the cheap jabsco
toilet before pumping, too much vacuum in the tank will drain the toilet.
At Dana Point
, the pump out pumps barely empty the tank. They just don't suck enough and it's like 7 feet of rise to pump up. They will not get it empty, it just gurgles with tons of stuff remaining in the bottom of the tank as well as the hoses.
I moved my macerator to always be primed, and I just dump it when out past 3 mi. The pump out docks are a pain. The one at Dana east has become home to a few large seals
-- not gonna mess with em.
