We're looking at spending the weekend on our boat and I need to pump out the waste tank. I've never done this before, and the manual doesn't give much information. Is it as simple as inserting the hose and sucking it all out?
How does this work? It must be vented somewhere, otherwise you'd create a vacuum in the system and nothing would come out. Is there a seal around the connection or long hose that reaches down into the tank?
I'd like to know what I'm getting into before I do it. I don't want to create a mess to start the holiday weekend.
