Saran Wrap is imprevious to odor. So it's a legitimate temporary
fix to an odor problem from a permeated sanitation hose. Peggie Hall often recommended wrapping a hose or section of a hose in response to forum participants asking how to deal with odor problems.
But, as she always stressed, it is NOT
a permanent fix and should never
be thought of as such. The only permanent fix is to replace the hose. Or replace the hose run with something that isn't hose, namely PVC tubing.
The plumbing run from our aft toilet to our aft holding tank by its nature holds waste in the aft end of the run before it goes up and into the tank. The original hose had permeated and was a problem, located as it is under the aft berth.
So we replaced the aft run with a length of PVC, which will never permeate. For the flexible bend from the lower pipe to the upper pipe that goes to the holding tank we reseached and found the most permeation-reisstant hose on the market and used that. It won't remain odor free forever but it should be okay for a number of years.
PVC plumbing must be protected from vibration or it will eventually crack. So the connections at each end of a PVC run should be a section of hose to "suspend" the PVC run. In a well-designed plumbing run, the sections that are hose will never be a collection point for effluent. If the hose is essentially empty other than when effluent is passing though it, it will be a long, long time before odor permeation becomes a problem.
