possible solution to sanitation hose odors?

[Mike8245]

Just an idea to bounce around, reread that OK. I am just starting to get a slight odor in the boat and assume the sanitation hoses are begining to permeate. I like the idea of minimizing the hose by using PVC for some of the line from the head to waste tank. Mine has a longggg sanitaion hose. I'm not able/interested in moving the waste tank, so rule that out. I am planning on leaving a couple of feet of sanitation hose at each end for good flexibility and running the rest in PVC.
Upon examining just how many hoses there are the system I am thinking the hoses that would likely permeate the fastest due to having waste sit in them whenever there is waste in the tank are the short hoses from the tank to macerator an tank to pumpout deck fitting. They are too short to use any PVC lengths. I am wondering if any has ever tried wrapping those short runs with something like heat shrink to block odor? I would be interested to hear if anyone has any opinions/ideas. What do you think?? Good idea, don't waste your time or have a better idea??
Thanks for your input in advance, the power of people can be great thing.

In googling heat shrink it appears to be made of polyolefins which has the following properties-----"In addition, it is highly rated for aroma retention, and odor ... makes it possible to co-extrude with not only polyolefins but nylon 6, nylon 66, .... Odor Proof".
Maybe it would be a reasonable premanent solution to block odor??...

Just repeating what has already been said on this site. Use non-permeable Trident Sani Shield Sanitation Hose #102. I did that on this boat recently and it completely eliminated any odor.

Easier said than done, it would be verrryyyy difficult to gain access to the hull side vent and pump out lines. The tank end while difficult, do- able.

I assume the access limitation would make it more difficult to install a wrap.

I don't think I've ever seen a boat in which access to certain hoses or locations wasn't limited.

Hoses, both fuel lines and water hoses, deteriorate

from the inside out. If the hoses are very old, I would replace them without a second thought. For some things there is no subsitute for periodic maintainance and this is one of them. I had a similiar situation with a shared boat that was over 20 years old. On an over night trip, the hose going from the head to the holding tank plugged and the trip had to be cut short. Back at the dock it was found that the hose deteriorated inside and caused the problem. Nobody had thought to make that a maintainance item and the original hoses gave out not surprisingly given their age. Replacing the hoses took up an afternoon, was tendious and of course messy. Had we done the job before hand, we would have done the same work except we would have enjoyed a beautiful trip to Catalina.
