Uphill installation is NOT inevitable...plus...

I wasn't aware of the warranty against permeation odor, and couldn't find one on Trident's web site, which appears to be less than fully functional.

Works fine for me...and the warranty length is plainly visible at the bottom of the descriptions all their sanitation hoses Trident Marine: Sanitation Hose

They DO warn against the type of installation which is almost inevitable on many boats, saying: "Longest odor-free performance on the market, but self draining installations still recommended. "


But they don't say that any other installation voids their warranty.

Self-draining would have to mean that it's a downhill run all the way to the tank. Not gonna happen unless somebody comes up with an in-keel holding tank!

Not true! When it's an uphill run to the tank--which it is on most sailboats, the uphill run can be minimized by installing a loop--not necessarily a vented loop, just an arch--immediately after the toilet, which makes it only necessary to pump long enough--and in the DRY mode, btw, 'cuz any toilet that's working anywhere near factory spec can move bowl contents up to 4 vertical feet and/or 6' linear feet in the dry mode (if it can't, it's way PAST time to replace the joker valve!)--to move contents over the top of the loop...gravity will do the rest. And learning to use the dry mode to do more than just push the last of the water out the bowl--leaving waste sitting in the hoses, btw--can also increase the number of flushes a tank can hold by as much as 100%.

However, the main thing you're overlooking is, clean water doesn't permeate hoses, waste left to sit in 'em does. So always rinse the sea water and waste out of the hoses before the boat will sit by putting a couple of quarts of clean FRESH water through the system--which you may have to add with a cup from the sink-- before the boat will sit.

I'll contact Trident and see what they say. Notwithstanding this issue, I'm still sticking with Trident 101, base on your (and their) claims of permeation resistance.

Good decision 'cuz nothing else even comes close to its permeation resistance, not even SeaLand's highly touted "OdorSafe"...I've personally been on at least half a dozen boats on which it had permeated within a year and heard of many more.

Catalina 27 Yorktown
Stinking Head hose

It's the hose. After a few years, the waste odor permeates the hose material and even though it doesn't look like it's leaking, enough of the waste is getting through the hose so the bad smell fils the boat. I replaced all the hose on my Catalina 27 (35+ years old) using a combination of hard PVC pipe and flexible hose. Problem solved. Don't forget to include a anti-siphon loop to prevent sea water entering when the boat heels hard over (Depending on the design of your boat). The Hard PVC works great and lasts a very long time but is harder to work with. You must plan each piece perfectly for fit. The boat will be MUCH nicer after you get that old hose out! :eek:
Good luck -



The head is new. The holding tanks is new. There are no leaks. Is it the old 1 1/2" hose? The smell is intolerable when we get on the boat. After some airing out and flushing, the smell goes away until we come back again after two weeks away.

Please help head mistress!

It was the hoses on YOUR boat...

And it MAY be the hoses on his boat. But that doesn't mean that it HAS to be. While permeated sanitation hoses are the most common source of odor on a boat, it's not the only source that can make a boat smell like a sewer. Jumping to conclusions instead of arriving at 'em through a process of elimination can become a very expensive series of trials and errors.

Bad hose

Yes it's the hose, you have to change it almost every two years, a friend had the marine head and it was bad.

Beneteau 473 Moorestown NJ
Freshwater solution

I changed both of my heads to freshwater and it made a world of difference in odor control. No more Chesapeake Bay organisms having a breeding ground in my system. I have a Beneteau 473 which carries 220 gallons of water in four tanks so I do have an advantage over boats with smaller fresh water tanks. Also, I installed a vacuum flush toilet in the stern head which uses a minimum of water with each flush.

Hunter 41DS Riviere Sens, Guadeloupe
Hunter 41 stink

I have a 41 DS and have a similar problem but only in the front cabin. I have a fresh water electric flush system, the holding tank is empty except for an odour killer and 4 gallons of fresh water. Why do you think the cabin has a distinct smell of doo doo? Checked the hoses, no leaks!
