You're confusing two separate problems, Cantata...intake odor, and permeated hoses.
Intake odor is caused by trapped stagnant sea water IN the inlet hose when the boat sits for a while. It's usually confined to the head, goes away when cleared out by the first few flushes...it can permeate the intake hose, but rarely does.
The hoses that become permeated with odor are those that carry sewage--the head and tank discharge hoses, and sometimes the tank vent hose. That odor can permeate the whole boat and does NOT go way with a few flushes because the hose has soaked the waste that produces the odor. The only cure is new hoses.
However, wet dirty sumps and bilges can also make a boat smell like a sewer...I've heard from many people who've replaced their entire sanitation systems to get rid of what they thought was "head" odor...when all they really needed to do was clean--really CLEAN, and flush all the dirty water out--their sumps and bilges.
To know whether a hose has become permeated with odor, wet a clean rag in hot water...wring it out and wrap it around a low section of the hose...let it reman till it cools, then remove it and smell it. If you can smell the same odor on the rag, that hose has become permeated with odor...if you can't, it's fine. Test every section of every hose, using a clean rag for each.

As I have mentioned in another thread, I am replacing my toilet...
It is not going well ...
Installing the toilet itself was no problem ...
But I have had a very frustrating couple of weeks trying to work with the standard 1-1/2" white sanitation hose for the waste discharge (the kind on offer at West Marine.)
It is virtually impossible to get it slip onto standard 1-1/2" hose barbs. I even soak the end in boiling water for a couple of minutes to soften it up, and use a liberal coating of dish-soap. But it still requires major force and major twisting back and forth to get it to go on.
So - point 1: it doesn't *stretch* enough to fit over a hose barb with a reasonable effort.
And then, once it is finally on and seated, with a couple of hose clamps tightened down hard ...
It still leaks!!
So - point 2: it doesn't *compress* enough to form a seal.
The problem doesn't appear to be something I'm doing wrong ... I've never had these kinds of problems with any other kind of hose.
The problem seems to be with the physical elasticity of the hose itself - it seems as though it is simply not elastic enough - it is too stiff.
I've tried everything to get this system to be leak free, and I am ready to give up on this hose.
Does anyone have suggestions for either
a) another kind of hose, or
b) a way to make this hose work?
