This past weekend I made a discovery regarding my holding tank. It seems the previous owner used the fresh water tank to supply water to the head.

Good thing I did not make any coffee yet<img src=icon_smile.gif border=0 align=middle>anyway shouldnt there be a "Y" valve just after the 1 1/2" sea water valve to supply water to the head and then to allow the head to discharge to the holding tank?

I looked at the manuals but they dont seem to indicate one.

Appreciate your replies

Frank,
I don't consider myself an expert, but I had a larger boat on Lake Erie with a "Y" valve on it and now have a C25 on a small inland lake in Ohio.
Your plumbing sounds a bit strange. I would not want my water tank linked to my holding tank, even for intake. The intake from the sea/lake is probably (originally) a "T" valve under the bow and in the middle of your boat. The other end of the T is the drain for the forward sink, I believe.
A "Y" valve is used (from my experience with a larger boat) as an alternative for where the DISCHARGE from your head will go. This may not exist on your boat. My earlier boat had a "Y" valve with which you could either discharge into your holding tank or !!! overboard. (Yes, overboard.) You may only discharge overboard well out to sea these days, so don't even think of this. I was required on Lake Erie to have my Y valve locked in the holding tank position.
Final advise in my opinion, get rid of the connection from your fresh water to the head intake. No Y valve necessary unless you are referring to what I have called a T valve under the bow.
Good luck, and I am interested in any other responses.

I was going to make a smart ass comment regarding the water flavor, but I can't even stoop to that level.

I can't really see why anyone would do that unless maybe they were very very opposed to bringing saltwater into the sanitation system. Some people do have a y valve for discharge, allowing them to either tank it, overboard it (where legal)...see the following link.

or combination thereof.

Get rid of the Y valve and seal the hole to your water tank...then sanitize the life out of it.

It sounds like a strange set-up to me. The two systems should be completely separate. If one did want to use fresh water to flush the head, it should be done by filling the head sink with water from the faucet (fresh water system) and then with the thru(to)-hull valve closed, drain the sink into the line. The water will go past the thru-hull and into the head intake when the head is pumped, keeping your fresh water safely isolated.

Thanks for not commenting duane, I cant imagine what my potable water would have been like. Anyway I did a major chlorination jodb to the potable water tank.

I think the reason for the set up was to try to prevent the smell from the head.

From what I have read on the subject micro and not so micro marine life--animal and vegetable--gets trapped in the head intake line, in the pump, the channel in the rim of the bowl, dies and decays...and as a result, the first couple of flushes after the boat has sat for a few days are RIPE. Worst case is sea water.

If you go www.sailboatowners.com and look up Peggie Hall / Head Mistress you can get information on the subject.

I’ve thought about piping fresh water to my head. And with the right flow and stop valves I’m sure it can be done. But I’d rather sail then work on my plumbing. So we keep a few 1 Liter bottles by the head and for number “1’s” a few pours and a dry flush seems to work keeping the smell down. For number “2’s” we switch to in take and use seawater. This method has kept the trips to the pump out station to a minimum by limiting the over pumping that happens when you flush.
