Stus-List Smelly head Update 

First off thanks to all that replied. the comments and advice were of 
assistance. Here is what I found out




1) There was old water in the fresh water tanks. yes i should have checked that 
first...Smelled just like sewer and I suspect that the stagnant hot water 
heater water was contributing to the smell under the vanity in the head




2) I discovered a loose fitting inspection port cap on top of the holding tank. 
This port is not visually accessible unless you remove the sink. I found it 
because when filling the tank with super chlorinated water I over filled it 
which caused some water to
 run down along the front of the tank. i was concerned that i had a crack in 
the tank. When i stuck my hand as far as i could from behind head, through back 
of hosing i touched the loose fitting port cap on the top of the tank. This is 
where the source of overflow
 water must have come from and in turn may have been source of odors as well.




So two culprits:

1) stagnant fresh water - emptied and cleaned tanks

2) loose fitting inspection port cap.- rinsed chlorinated, repeat, tighten 
inspection cap




learning lots about our new boat 🙂 now on to change out secondary fuel filter




Cheers,

If you are looking for a chemical solution to fight odours, there is a product 
called “PureAyre” that can help.
 It kills smells, but you have to stop the leaks etc. or it won’t help you much.

The worst smell is when the boat is sitting and all the algae in the *intake 
line* rots. Then the first time you pump it the smell could knock a buzzard off 
a septic tank truck.


One stopgap for smelly hoses is to get tea tree oil and spray the hoses down 
with it. It does a decent job killing organic odors. If you want to be 
scientific, bubbling oxygen through the holding tank would be a help too.

I went as far as putting in a y selector on the intake hose for the head and 
plumbing it the to fresh water tank with a back flow preventer so that the head 
flushed with fresh water.  That is easier than using the sprayer for flushing. 
There is a little more resistance when in wet flush mode but it works great and 
has really cut down on odor (along with replacing hoses).  Of course we are at 
a dock so filling the fresh water tank more often isn’t a big deal. I put the y 
valve in so that for longer trips it can be switched back to seawater if 
desired.

There is a lady named "Peggy Hall" that is active on one of the online boating 
forums. She is nicknamed the "Head Mistress" and has written a book about 
marine heads and head odors.

One of her tips is to use a cloth dipped in hot water. Touch it against the 
thing you think may be the source of the odor for a short time, then smell it. 
For hoses, wrap it around the hose. That should help you nail down the source 
of the odor.

As someone said, even the best head hoses don't Las forever, especially if any 
black water rests in them for any length of time.

You can flush with sea water all day long, but use the fresh water as the last 
flush of the day, before leaving the boat. This should prevent any smell from 
the bowl itself.

Even the good read expensive hose smells bad after a while. If yours is still 
original it's probably due to be replaced. Possibly the tank as well. I've 
heard it is better to use fresh water from the head faucet to flush rather than 
sea water too. What we did to get rid of the smells was to yank all of it out 
and go with a composting head. So far so good. Good luck.

Re: Stus-List Smelly head

[Dave S via CnC-List]

Replaced smelly hoses with the spiral pvc type, this lasted 2 yrs before they 
were permeated again.  Replaced with the spendy  Italian rubber ones this 
season.  Check by smelling the hose itself.  

Backflow issue is almost certainly the joker valve.  Best is annual replacement 
and check for seal (visually) on new ones.

Check that vent is clear.

My pump occasionally pressurizes and this is a result of the dry/wet valve not 
functioning correctly- try holding it to one side while pumping. 

If I am not concerned with water consumption I flush with the potable water, 
which I spray into the bowl with the shower wand.  

In winter when the boat is covered I remove the plug from the pump out fitting. 
 Fresh air can’t hurt

Good luck.

Stus-List Smelly head

[Len Mitchell via CnC-List]

Blair, one thing worth mentioning is tank construction, some boats of that 
vintage including ours came with an aluminum holding tank. The PO used a 
chlorine odour product and the tank disintegrated along the bottom edge. If 
yours is plastic, that’s better than aluminum and I would check the inspection 
port because they can also crack. If the smell goes and comes back with the 
valve closed it’s probably not your tank. Sometimes a flashlight and small 
mirror are your best diagnostic tools. You should also have a vented loop you 
can check up high behind the head. Let us know how you make out.

Re: Stus-List Smelly head can be a happy head

[Dreuge via CnC-List]

Hi,

I would start simple.  What you describe (i.e. the back pressure and recurring 
stink) sound like one but possible two problems.  I would first check the 
holding tank vent line.  A blocked vent line will lead to back pressure in the 
holding tank and little to no oxygen diffusing into the holding tank to promote 
aerobic decomposition.  Without oxygen, the smelly anaerobic bacteria take 
over.   Sea water stink is another problem caused by anaerobic decay of organic 
matter in sea water and while it has nothing to do with fecal matter, it can 
smell just as horrible.  The later problem is more notable in the summer 
months, but is easy to fix by teeing the head inlet to the sink drain.  When 
the seacock is open the sink drains and the head inlet uses sea water to flush. 
 When you leave the boat for an extended period, close the sink seacock (a good 
think to do) and run some fresh water into the sink, pumping the head to flush 
the fresh water through the inlet line.  It is amazing how much of an impact 
this has.As for the tank, some suggest adding a large vent hose, but one 
can simple add an active ventilation system rather cheaply (or install the 
equivalent but costly Sweet Tank system from Groco).

Here are links to my write ups on removing sea water stink and on installing a 
simple and effective active ventilation system using less that $25 worth of 
aquarium parts.

At the very least, check the vent line and seriously consider using a sink tee 
inlet.   Hoses do need to be replaced especially if your hoses were crap to 
begin with.  My old C&C 29 came with a bit of a funky smell which turned out to 
be coming from a section of cheap clear vinyl hose used to go from a Y-valve to 
the holding tank.  I good hose is expensive but worth it.  I prefer Trident 101 
hose.

Re: Stus-List Smelly head

[Ken Heaton via CnC-List]

There is a lady named "Peggy Hall" that is active on one of the online
boating forums. She is nicknamed the "Head Mistress" and has written a book
about marine heads and head odors.

One of her tips is to use a cloth dipped in hot water. Touch it against the
thing you think may be the source of the odor for a short time, then smell
it. For hoses, wrap it around the hose. That should help you nail down the
source of the odor.

As someone said, even the best head hoses don't Las forever, especially if
any black water rests in them for any length of time.

I've heard it is better to use fresh water from the head faucet to flush
rather than sea water too. What we did to get rid of the smells was to yank
all of it out and go with a composting head. So far so good. Good luck.

Re: Stus-List Smelly head

[Bruce Whitmore via CnC-List]

Hi Blair, 

I have a number of thoughts:
1).  The backflow into the head is likely caused not so much by the joker valve 
as the flapper valve at the bottom of the pump itself where it is screwed to 
the pipe leading to the bowl.  You can take it apart and clean it manually (4 
screws) but realistically if it is bad, you're better off buying a whole new 
Jabsco pump (not the whole head).  They are almost the same price as an 
overhaul kit but are a lot easier to replace.
2).  Back pressure on the handle is generally caused either by not having the 
flip-style valve all the way to the right when pumping or a blocked vent.  
Check that vent!  They tend to get clogged with spiders and such that like to 
make it their home.  Check it every time you pump out as well, and even flush 
it with water each time.  It's remarkable, as on other boats I've even found a 
holding tank bowed out to the point you could stand on it from the increased 
pressure, but as soon as I poked around the vent a little bit the pressure 
hissed out of the tank immediately.
3).  To test the hose for permeation, wipe it down with a damp rag or paper 
towel, and smell it.  If the smell transfers to the towel, your hose is due for 
replacement.
4).  Flush, flush and then flush some more!  Inevitably I find smells that come 
from the head and holding tank are almost always caused by people wanting to 
conserve how much water they pump through.  I get that people don't want to 
fill their holding tanks, and the fact that I can flush seawater back out like 
you can means that I can pump waste into the tank, but use seawater to flush 
lots of water through the system and back overboard afterwards.  We've never 
had a problem with smells since.  As to the issue of fresh vs. salt water, I 
understand why people use fresh water to flush, but if you're not putting 
enough volume through, I personally think it is counterproductive.  

5).  If you want to clean the holding tank, I would fill it about 1/2 way after 
adding Dawn or other detergent and go sailing on a windy day to slosh it 
around.  Then pump out.  

Hoping you find this helpful.

Re: Stus-List Smelly head

[Lee Youngblood via CnC-List]

Hi Blair,

Yes replacing hoses may be required, and WM will push you hose right away!.  
First I’d go to the pump-out on a weekday, suck everything you can, fill and do 
it again.  If nobody is waiting maybe even a third time if you are new to the 
boat.  Pour a couple gal. of water or run the hose into the toilet and really 
flush out the bottom of the tank. Sailing and banging the boat helps shake the 
old flakes out.   

The vent is critical, and must be clean!!!  Repeat:  The vent is critical, and 
must be clean!!!  Run water through the vent line so it’s being sucked in, 
while sucking out the tank.  If you don’t hear it gurgling and sucking - your 
vent hose is plugged.  Usually with old shit or maybe bugs. Maybe you can get a 
wire in to help, or replace that line first.  The bugs that grow in the tank 
with-out air, really smell the worse!  

When you have a clean vented tank, at Noflex, mix like yeast.  It’s the dried 
version of the “bugs” that you want in your tank.  Kathleen flushes maybe a 
quart through the system after pump outs.

Use your boat all year if possible - it might take a year or two, some hard 
sailing, and a lot of flushes before you see very few dried compacted flakes 
being sucked out.

We bring a few 1/2 gal. milk jugs down to the head, and flush with fresh water. 
 If you are day sailing and back to the dock, and it’s easy to top up you water 
tank, flush with the sprayer or a jug.  Whenever you leave the boat, even an 
afternoon, especially for a week or more, flush with fresh water! 

Some folks have a pump-out service, and you should see how quick they can 
“service” your boat, likely on and off in under 3 min. - ouch!The nice 
thing about going to the pump-out - you are using your boat, which keeps many 
systems working, tips you off on the problems, and gives you lots of practice 
docking - a very good thing.  Again, try to go weekday mornings, not Sunday 
afternoons when everyone is cranky and eager to get off the boat!  Never on 
Labor Day!

Hope this helps, Lee

Re: Stus-List Smelly head

[David Castor via CnC-List]

I'd suggest Peggy Hall's book on head odors.  Still in print, I think.  I
agree with previous comment that stagnant seawater used for flushing can
create an incredible foul odor.  Flush some fresh water through the head
into the tank. There is a simple test for condition of hoses.  Covered in
Peggy's book and in Don Casey's book.I wouldn't start tearing things
out just yet.  But replacing existing hoses can't hurt.  Good luck.

Re: Stus-List Smelly head

[Shawn Wright via CnC-List]

Our 35-2 is similar, even with new hoses and a clean tank. Much of the
smell is from organisms in salt water decomposing, as it occurs even when
the holding tank is empty. I've been told that adding over sized venting
for the holding tank will help, to reduce the anaerobic bacteria which is
causing the smell due to lack of oxygen. This is on my list.

I suggest flushing some water into your vent line(s) from the outside to
ensure they are not plugged. In our case, the tank vent is tied into the
anti-siphon (upside-down U) on the bowl flush line, so when flushing, some
air is being drawn from the tank instead of outside, causing the smell. I
plan to add a separate vent for the head flush line to prevent this.

Even the good read expensive hose smells bad after a while. If yours is
still original it's probably due to be replaced. Possibly the tank as well.

Stus-List Smelly head

[Blair Clark via CnC-List]

I beg patience as i am hoping there is some quick troubleshooting hints that 
can be provided.

Purchased a 1990 C&C 34 +. really really happy with boat and currently working  
through some smaller items to get her up to speed.

one of these involves the holding tank. My jabsco manual toilet exits through a 
Y valve to sea or to  holding tank.  No external macerator system is in place.. 
Even when Y valve set to sea I am having a smell go away and then return to the 
head area.

Holding tank was pumped before transport after purchase and appears close to 
empty.

Steps to date:

1) Had a group out on the boat
2) next day head ines appeared blocked as there was back pressure on handle
3) removed lines got shop vacuum cleared lines and flushed with vinegar and 
water
4 thought everything would be good
5) Noticed smell in head
2) noticed back flow of liquid into bowl
3) again fought with stiff lines and replaced joker valve
3) back flow and  Smell went away
4) a few days later after not using boat the smell came back but not from 
toilet bowl
5) noticed that when I opened door under vanity sink bowl in the space that 
houses the holding tank that the smell was more extreme
6) thought of taking tank out to inspect during winter but have no idea how to 
access it to do so.

Does anyone have any suggestions as to troubleshoot tsmell, holding tank or 
lines and or remove tank?

Thanks,

Stus-List Smelly Head and Tank

[Bob Hickson via CnC-List]

I have an identical C&C 29 mk 2 that I purchased in 2012.

I replaced the head the first year as it was in very bad condition.

Last year, I replaced all the hoses between the head and the tank and
cleaned out the tank. 

This reduced the smell but did not eliminate it.

Earlier this year, I replaced the vent hose and cleaned out the thru hull
breather vent (full of spider webs).

The vent hose that I installed was ¾ inch and it needed different fittings
at the tank and vent ends.

Once this was completed, the smells have totally disappeared in the cabin.

There is still a lingering odour in the 2 small bow lockers adjacent to the
tank.

Mine boat is a fresh water boat.

Re: Stus-List smelly head and tank

[Debra Crockett Morgan via CnC-List]

We have an airhead composting toilet as well. We are quite pleased. Even though 
the PO had it all pumped out, cleaned out, etc, we hated smelling the tank, 
hoses, and stuff. And we had never even used them because we don't have a pump 
out facility on our reservoir! The day we pulled the head and the tank out was 
a happy one for me. And the Air Head is great!!

I am converting to a composting toilet (Air Head) in a couple weeks.  I don't 
understand why more people on this list have not done the same.  When I go into 
someone else's boat I can almost always smell their holding 
tank/hoses/whatever.  I think people just get used to smelling it and don't 
notice it after a while.  I think they are all smelly.


Flushing with fresh water helps because it eliminates the odor of dying sea 
creatures that would come in thru the seawater intake but it does not eliminate 
all odors since the primary substance being flushed is still smelly.


A larger vent will probably help the most (even up to 1" in diameter).


We only have a 15-gallon holding tank which only lasts a few days at most.  So, 
frequent pump outs are necessary and it is becoming costly.  The Air Head will 
pay for itself in 2 to 4 years based on saving pump out costs alone.

Re: Stus-List smelly head and tank

[dwight via CnC-List]

About 5 years ago I removed a Wilcox Crittendon Headmate from Alianna and
replaced it with an electric marine toilet.  At that time I also replaced
all of the associated sanitary hoses and valves.  I flush only with salt
water and have never used the holding tank even though I have it setup to
use at the switch of a 2-way valve. I have never added chlorox or for that
matter anything else, except in winter when the entire system is filled with
a 50/50 automotive ethylene glycol/water solution.  I have not experienced
any head related odors since this change over and now after installing a 4
inch solar vent in the main cabin the boat interior smells quite fresh even
after several days of being locked up on the mooring.  I believe the biggest
improvement resulted from installing the new valves and sanitary hoses. I
always do a lengthy flush before leaving the boat, but that flush is still
done with salt water.  I feel very fortunate for my situation but I can
assure you that changing out the old head and sanitary hoses was a very
unpleasant job.  I am not sure what useful lifetime this system has but my
experience suggests that old sanitary lines can contribute to head odor
related issues and when I start to notice odors again I will take it as an
indication that those lines need changing.

Re: Stus-List smelly head and tank

[Tim Goodyear via CnC-List]

Hi Bev,

A couple of things from my experience of a smelly tank after launch this
year:
- If the holding tank is smelling, make sure your holding tank vent is
working.  Anaerobic bacteria cause the particularly noxious smells; they
are replaced with aerobic, less smelly, bacteria if there is sufficient
oxygen supply.  My solar powered fan on the fore hatch broke early this
season and the tank started smelling.  Replacing that vent fan seemed to
cause enough ventilation of the tank (under the v-berth) to solve the
issue, so any minute air circulation will help (the vent wasn't blocked).
 Similarly, getting rid of mud from a wasp nest in the vent hull outlet
solved an issue a couple of years back.
You are going to have some salt water / waste in the tank regardless of
ending the flush with fresh water.  Vinegar dissolves salt residue in the
hoses / tank - flushing a few gallons of white wine vinegar through the
head and then a nice upwind slog into steep chop should clear any build-up
out at the next pump out.
- if the head is smelling, the fresh water flush will prevent decomposition
in the bowl, but make sure that the valves on the head pump / outlet aren't
letting anything to flow back from the outlet hose.  The joker valve is the
usual suspect, but if you're having to pump a lot to prime the pump to get
flush water flowing, or to empty the bowl you may want to check the other
pump valves too (advice from the list would be to replace the pump assembly
completely).

Hope this helps.

Re: Stus-List smelly head and tank

[Marek Dziedzic via CnC-List]

I second the idea of flushing with fresh water. What really counts is the last 
flush before leaving the boat. It makes a big difference. 

This applies (I hear) especially, if you sail in salt water, but even on a 
lake, the outboard water is not as clean as we would want to believe. So I use 
either water from the sink/shower head or simply some drinking water from a 
bottle. I know of some people who re-plumbed the water intake for the head to 
use the same through-hull as the sink drain. That way you can close the 
through-hull, fill the sink with water and pump it through the head.

Prevention rather than cure...

Here is what I do. Rarely if ever do I have bad head odor 

Flush only with fresh water - I use the shower head from the sink to flush. 

Pump out regularly - I pump out after each weekend night away, and as 
frequently as possible on cruises. 

Flush thoroughly with fresh water each pump out. I pump lots of fresh water 
through the head as well as filling the tank via the deck fitting. Repeat until 
pump out  "glass " shows clean water.
