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
