All this chatter about plumbing raised, for me, a related question for you 37+ 
guys.
I am changing a leaking, not really serviceable toilet to a new one, and plan 
to change the hoses as well.  On the 37+ there appears to be no 
factory-installed vented loop on discharge line.  Not one on my ex-boat, a 35-3 
either.  Seems that a vented loop is recommended by toilet makers to avoid 
backup when heeling.  
Has anyone upgraded and installed vented loop?  Or is there a rationale for not 
having one on our boats?  Puzzled.

Re: Stus-List Head Plumbing

[Randy Stafford via CnC-List]

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. 

Cheers, 
Randy

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. 

Cheers, 
Randy

Your head inlet teed to the sink drain is exactly the way my 38 is plumbed. I 
think that arrangement was pretty common in the 70s. 



My question is why you would close the sink drain seacock when under weigh. 



I have a shut off valve in the inlet line between the seacock and the head that 
is near the head, and the lever on the head that is marked “Flush” and “Dry” is 
always left on “Dry” – and either of these should prevent inlet water from 
siphoning into the head when the boat is heeled while sailing. Is your boat 
plumbed with a shutoff valve near the head? 



Personally, I close all my seacocks a couple of times a year to make sure they 
are moving freely and they remain open the rest of the time; though I know 
there are some on the list who close all the thru hulls when they leave the 
boat for a week or two as insurance against a hose leak.

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

It's the intake hose I'm wondering about. I suppose with the vanity sink drain

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

Does that sound reasonable, or is my boat's head intake plumbing screwy?

yea that is that Raritan fresh head kit. it is supposed to work with 
most modern toilets as a simple bolt on.  It ads a vacuum breaker to 
make it safe to connect to boat fresh water supply and gives good 
quality Raritan pump.

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.

Hi Ken,

If the just gets casual use, an inline ball float check valve might prevent the 
unintended washing. From that annoying port hand basin.

This is similar to what I was thinking about, but it doesn't have the ball so 
the seal isn't as good.

Re: Stus-List Head Plumbing

[Rick Brass via CnC-List]

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.

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?

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.

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.

Re: Stus-List Head Plumbing

[Rick Brass via CnC-List]

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

[Randy Stafford via CnC-List]

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. 

Cheers, 
Randy

Your head inlet teed to the sink drain is exactly the way my 38 is plumbed. I 
think that arrangement was pretty common in the 70s. 



My question is why you would close the sink drain seacock when under weigh. 



I have a shut off valve in the inlet line between the seacock and the head that 
is near the head, and the lever on the head that is marked “Flush” and “Dry” is 
always left on “Dry” – and either of these should prevent inlet water from 
siphoning into the head when the boat is heeled while sailing. Is your boat 
plumbed with a shutoff valve near the head? 



Personally, I close all my seacocks a couple of times a year to make sure they 
are moving freely and they remain open the rest of the time; though I know 
there are some on the list who close all the thru hulls when they leave the 
boat for a week or two as insurance against a hose leak.

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

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.

Your head inlet teed to the sink drain is exactly the way my 38 is plumbed. I 
think that arrangement was pretty common in the 70s.

 

My question is why you would close the sink drain seacock when under weigh. 

 

I have a shut off valve in the inlet line between the seacock and the head that 
is near the head, and the lever on the head that is marked “Flush” and “Dry” is 
always left on “Dry” – and either of these should prevent inlet water from 
siphoning into the head when the boat is heeled while sailing. Is your boat 
plumbed with a shutoff valve near the head?

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

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.
