[C320-list] Water system, newbie questions

[Kevin]

Warning: 320 newbie questions ahead:

I'm still quite new to my 320 (#211, 1995) and have figured out the basics of the and rebuilt the head system, but the fresh water system I've really not used yet.

Can someone give me the basics of what I need to do to use it? Or point me to a manual or online info? I think I have it working but it it would be nice to get some confirmation so I don't screw anything up.

Which seacocks do I need to be open for drainage? Just the one under the sink?
Do I leave the panel switch that reads "water pres/shower pump" in the on position?
Also, can using sea water make the head smell? I've been keeping it empty and, as I said, rebuilt it, but there is still a bit of a funky smell. Might using fresh water reduce this, and if so, how do I switch the system to get water from the tanks rather than salt water?

Thanks for any help you might be able to provide, and have a great holiday weekend!
