Re: Stus-List Head Plumbing
Turns out my boat does not have a shutoff valve near the head, as discussed below. It does, however, have a shutoff valve between the sink drain and the through-hull. I don't understand the point of that at all. I suppose I could put a shutoff valve in the head intake hose. But between the seacock, sink drain shutoff, and head wet / flush lever, both the sink and the head are double-protected already.

yea that is that Raritan fresh head kit. it is supposed to work with most modern toilets as a simple bolt on.

Re: Stus-List Head Plumbing
The drain line from my vanity sink (with check valve) is teed into the intake for the head. You do your business, wash your hands (you all do that, right?) and the sink water leaves a layer in the head that seems to cut down on odors.

Re: Stus-List Head Plumbing
Actually, you just need to have the T in the sink drain well below the waterline and near the seacock. My vanity sink is on the port side, and I do notice that I get air trapped in the inlet line to the head after being heeled to starboard while sailing. I presume that air gets into the line from the sink drain when the heeled waterline drops on the port side and some air gets trapped in the high point of the inlet line. Takes a few extra pumps to get the air out of the line and water flowing completely after the boat returns to the normal lines. I probably should change the hoses and lower the location of the T as much as possible, but it really isn’t a high priority change since a few extra pumps isn’t a real problem.

Re: Stus-List Head Plumbing
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.

Re: Stus-List Head Plumbing
On the 38, both the head and the galley sinks are almost on the centerline so it would take a near 90 degree knockdown to have them fill up with water. The head, OTOH, is well outboard and the seat is only a couple of inches above the waterline – hence the need for the shutoff valve in the inlet line.

Re: Stus-List Head Plumbing
Hi Rick, If it's not necessary to close the sink drain seacock when under way, then I guess I don't have to. I just assumed it was a good idea in case at high heel/roll angles or when pitching raw water would back into the sink (I saw that happen on a Merit 25 once). I'll check whether my boat has a shutoff valve near the head. The head does have the flush / wet lever of course. Thanks all for the responses.

Re: Stus-List Head Plumbing
Count me in the camp that closes all the through hulls. A discussion recently about disintegrating valve and hoses and the bilge pump keeping up keeps me ever vigilant to the possibility of sinking. It's usually just a sink drain and the engine cooling. I keep the engine key hanging on the engine through hull so I don't forget to open it.

Re: Stus-List Head Plumbing
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.

Not an uncommon configuration. I've seen it before. Dennis C.

Stus-List Head Plumbing
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?
