[C320-list] Valves & pump out procedure

[Kevin]

I'm still a relative newbie to my '95 C320 (#211) I have some newbie-type questions:

(1) There are three valves in a locker that opens to the aft cabin. They are unmarked on my boat. I know the forward one (further away as I reach into the locker) is for the shower sump. I assume one of the other two is to bring sea water into the head (but I don't know which one that is), and I'm not sure what the other is for at all.

Can anyone explain these for me, and let me know when certain ones should be open/closed?

(2) Related question: When pumping out the holding tank, which, if any, valves should be open. And should the water/no water switch in the head be open?

I know these are basic but I'm reminded of the thing said in grade school about the only stupid question being the one that isn't asked.

Thanks for any help you can provide.

Regards,

Kevin
