Stinky Head? Permeated Hoses? Solution!

I have never sailed in salt water only fresh but still have the same problems. BTW I installed a SCAD tank monitor, best thing ever.

Sea water stagnates and stinks in the intake line, pump and channel in the rim of the bowl...flushing with fresh water does eliminate those odors. However, a joker valve that's so worn that the slit has become a hole will allow odor from the tank and from sea water and/or waste that isn't rinsed out of the discharge hose to escape into the toilet. The solution in both sea water a fresh water toilets is, flush about a quart of fresh water at least daily--and especially last thing before closing up the boat, and replace the joker valve annually.

The only comment I would add to Peggy's advise is that although the Raritan hose will bend tight, don't force it beyond what it does easily. There have been a few kinks. If you feel like you have to force it (as Peggy will agree) add a 90.

12 strokes with the handle would empty my hoses, that is 12 flushing and 12 drying.
Just pumping feces "out of sight" will cause bad things to happen.

So this past weekend I wrapped my hoses with foil tape which was a bit of a task. This tape is really sticky and due to access can only use about a foot each time. I was somewhat sceptical whether this would work but the smell from permeated hoses went away. My boat gets hauled out in October for the winter and I plan on replacing the hoses in the spring prior to launch so wrapping the hoses was a great interim solution. In fact I plan on wrapping the new hoses prior to installation. Thanks for the great idea.

In an installation that's not suitable for Trident 101/102, Raritan SaniFlex hose is the best choice..

Much of the discussion has been about the hose quality, but equally the issue is having a discharge system that allow waste to accumulate and sit in the hose. It seems to me that is a poor design. I've used the cheap WM hose without such smell, but I placed the tank not far above waterline with a steep, continually downhill discharge to the through hull. Not only does this prevent sewage from sanding but also allows sea water to flush the hose. Also no pump or pumping required to empty the tank.

When you say through hull are you referring to overboard discharge? In the Great Lakes (fresh water) this is illegal so the only option is a hose to my tank. I suppose there is another option that being composting toilet.
