thanks everyone for the ideas. i had searched thru peggy's book and
could only come up with white vinegar. i also tried some stuff sold
by a nearby pet store as a cleaner used by vets/kennels to clean up
odors - it's an enzyme product like pure ayre. and i opened up all
hatches and put a fan where the tank had been and ran that for about 3
days. it's a lot better - but the odor must have gotten into the
glass where there's no gel coat. i'll try the other products next.
consensus seems to be to put in as much rigid pipe as i can fit. i
take that to be pvc - sch40. i'm offshore most of the time so my set
up is this - one hose from bowl to holding tank; one hose tank to
y-valve; one hose from valve to pump out on deck - the other to a
manual pump overboard. i think the worst hose was the one from the
pump overboard. i think i need to fill the tank with water after i
pump it out and pump it again to make sure that hose is clean.
while i'm at it - i'm going to implement an idea from the capt who did
the survey for me - he said to put a second vent on the other side of
the hull - there's always a pressure difference to cause air flow.
any comments are welcome. and thanks again.

i have removed the permeated (and smelly!) sanitation hoses along with
the holding tank and vent hose. i have a strong lingering odor where
the hoses were. i am in the process of replacing all hoses along with
the holding tank - but i would like everything to be odor free before
i install anything. i would appreciate any ideas.
thanks - bob t

I only just discovered Pure Ayre (and btw, white vinegar prevents
mineral buildup in hoses and retards odor permeation...I've never
recommended it to eliminate odors elsewhere in the boat). Pure Ayre
apparently uses a different "breed" of enzyme than is found in other
products...'cuz I've never heard of an enzyme product that'll eliminate
diesel odors before, only organic odors. But according to the feedback
I'm getting from people who've used it, it does!

i also tried some stuff sold

I suspect you just didn't use enough to penetrate all the way into
cushions and carpet and/or didn't get it into every "nook and cranny."

Try it again...this time, move all your cushions and anything else that
isn't nailed down out the sun to dry for a day.

I don't think so...

More likely the hose from the tank to the y-valve...'cuz waste will
always sit in it. Do you have enough space above the top of the tank
(5") to move the discharge fitting to the top of the tank (pickup tube
inside the tank? If so, there's a li'l doodad called the UniSeal that
makes it fairly easy to do.

i think i need to fill the tank with water after i
pump it out and pump it again to make sure that hose is clean.

Maybe...maybe not. It depends on how your tank is currently vented
now--length of the vent line, where it goes. You may be able to
accomplish just as much by replacing your existing venting with one that
has a larger diameter, and maybe moving the thru-hull.

If you want to discuss in detail, email me at phnlr-bbs (at) yahoo (dot)

Peggie, could you elaborate a bit on the "solely for long strait
runs"-part. As you describe it, I suspect only a very few
installations are suited for using hard pvc.

You suspect correctly.

I installed hard pvc by using a heat gun and some 45 degree bends.
I made "the soft connection" on both ends and I used rubber fasteners
every 30-40 cm to ensure proper fixation and thus reliability.
In my view hard pvc (installed with care off course) is superior cause
it's really non-permeable and *stays* non-permeable. Next to that it's
a lot cheaper than these top-quality hoses.

It is indeed cheaper and non-permeable...but there are trade-offs--a LOT
more cemented inline fittings (cement can crack under stress, fittings
create "bumps" where waste and sea water minerals can get caught and
build up)...it gets very brittle below 40 F, which makes shock
absorption very important...and every "soft" connection is another
union. Attention to detail is VERY important when installing hard
pipe...'cuz any stress, even just pulling it a couple of inches to one
side, can result in a failed connection somewhere. Hose can just be
installed and pretty much ignored except for checking hose clamps
until/unless it starts to stink...but in some installations, hard pipe
can be more maintenance intensive than hose. About the only place I'd
put it in most boats under about 40' is the first section of pumpout
hose from a discharge at the bottom of the tank--a piece to the top of
the tank...'cuz that's the one section of hose in which waste must
always sit.

Try baking soda and bleach. It worked for me

I think the doctor has an ointment for that, too.

Hi Peggie,

What have you heard about PureAyre? I tried a small bottle and it
certainly seemed to help. Seems better than ozone. On the company's web
site they suggest using a fogger to really spread it around. This seems
a great way to get into the odd corners of the bilge. Have you heard of
any using PureAyre with a fogger?

This is the best flexible hose to use, where you need to connect the
rigid if you use it: http://www.aussieglobe.com/avs96.htm. This is what
Sealand used to sell as Odorsafe, but they supply something else now
that doesn't work as well and is more expensive. As far as getting rid
of the current odors, a good scrubbing with simple green or any good
cleaner works great. If that fails, PureAyre odor eliminator seems to
work great. http://www.pureayre.com. No commercial connection, just a
satisfied user.

I second Keith's recommendations--both hose, and what to use to get rid
of the residual odors. I've just discovered PurAyre, and from the
feedback I've gotten it WORKS!

As for whether to use hard PVC....it's only recommended for long
straight runs. And it also should be "soft coupled" to anything rigid
(toilet, tank, y-valve, macerator pump, thru-hull) with enough
hose--about a foot--to cushion it from shock and flex. If you don't, it
can crack. So unless you have long straight runs, I suggest you go with
the AVS96 hose Keith recommended.

They have a website: http://www.pureayre.com If you don't like any of
their "internet special" packages, they have a toll free number you can
call to order it in the size you need.

I don't have any experience with it yet...I only know what they claim,
and the comments from a few other people who've used it and also claim
it works. So I'm not recommending it yet, just suggesting you give it a
try, 'cuz I don't recommend anything I'm not 100% sure about. So if you
do buy it (and I wish you would, 'cuz real world "field tests" are the
ONLY valid tests), please let me know how well it works.

Gosh, they even have a "marine formula". Same product, higher price?

I believe it's the same price, but you'll have to ask them.
