Marek,
I believe the tee would need to be below the water line and the thru
hull valve would need to be closed to utilize the grey water from the
sink drain. So, either way the line would be flooded. If the tee were
not below the water line, I think the stopper might work for the raw
water flush.

Actually, the #2 reason still applies (I guess depending on the
lake/river). I sail on a river and there is enough organic matter in
the water that it makes a lot of sense to flush the head with fresh
water before leaving, even for a few days.
I don’t have this configuration, but I know many people who do. I use
left over bottled water and it works, as well.
I am actually thinking about re-plumbing my head this way; however, I
am not sure how well it would work for using the outboard water. In
order to pump water into the head, you need some suction, but with the
sink drain on the other end of the run, you should suck in mostly air.
I guess you need to have the drain closed by a stopper, don’t you?
Any comments on how it works in real life?

Hi Randy,
This is the way I plumb my head basin & toilet intake many years ago.
The reasons are two-fold, I eliminated an unnecessary thru-hull
penetration and if we're going to be away form the boat for a couple
of weeks or more, I pump a 1/2 sink of fresh water through the toilet
to eliminate standing water containing organics (sea water) which will
yield a sulphur aroma on first use when we return (due to
decomposition of said organics).
If you're a lake sailor the reason #2 doesn't apply much. My basin
drain/toilet intake thru-hull valve stays open when we're aboard,
sailing or not.
Cheers, Russ

Listers-
If you'll humor me again, I'd like to get your comments on how the
head on my boat (30-1 #7) is currently plumbed.
The intake hose is teed into the vanity sink drain to its through
hull. The discharge hose goes to a holding tank only (no Y-valve for
overboard discharge).
It's the intake hose I'm wondering about. I suppose with the vanity
sink drain through-hull seacock closed, e.g. when underway, I could
pump fresh water into the head by first pumping it into the vanity
sink and letting the sink drain. When not underway, with the vanity
sink drain through-hull seacock open, I could pump raw water into the
head.
Does that sound reasonable, or is my boat's head intake plumbing screwy?
Thanks,
Randy
