This is interesting, Danny. After reading your post, I just found this:
Re: Boy do I hate that dang white sanitation hose... First, I should say that I ASSUME the Bellowflex hose that I replaced with the white stuff was original since the PO kept thorough records of everything they did and there was no mention of changing any waste hoses. The boat never had any waste odor and testing the old hoses as per Peggy's method did not reveal any permeation. However, I decided to replace the hose based on reading Peggy's info, assuming that the hoses would soon cause a problem being so old. Krush - In retrospect, I think the old hose might still have been just fine. They generally looked OK though there were some cracks in the exterior wall in some areas with tight turns. But again - there was no odor. Now, the only white hose that is still on the boat is that portion I mentioned in the first post. All the rest is has been replaced. Interestingly, a couple of hours ago I got on the Trident website and they now comment on the fact that the white vinyl sanitation hose that they sell is prone to early permeation under various conditions that could be quite common. I suspect that since the hose is used in/through the eng room (heat) and there are waste treatments systems on the boat (chlorine), these adversely affect the hose. Here is the quote from their site: "Sewage allowed to set in the hose develops acids and gas that shorten its odor free life. This is especially the case with our most popular white (vinyl) XHD Sanitation Hose (#148 series), where petroleum based lubricants, excessive heat softening, and fluids containing alcohol, petrochemicals or solvents can damage this hose and shorten its "odor free" life. This is a good and cost effective sanitation hose, but for maximum "odor free" performance, and long &/or non self-draining installations, we recommend our Premium Sanitation Hose (#101 series). It’s heavy wall, 2 ply with wire helix construction is more forgiving, flexible, installation friendly and odor resistant. " It sounds to me like even Trident doesn't think it's very good hose! I used the flexible PVC hose that the big box stores sell for hot tubs, and have been happy with it, no odors. This 101 sounds better though, and not that expensive, and probably easier to hook up.

I said, "Not really." She said "oh good! use the trident 101 hoses. I don't know of a single case where they have ever had a permeation issue." I guess I'm going to have black hoses...I guess I could paint them if the admiral has an issue with them... She also suggested a 24 gallon tank at least. She said, on average, a manual toilet uses .6 gal/flush and the average person uses the toilet at leas 5 times per day. So, at a minimum your putting 3 gal/day/person in the the tank. For 2 people you get 6 gal/day so that tank will not even last 4 days because you don't want to be filling it to capacity. So, we (she) decided the v-birth would be the best location for the new tank. I'll be heading down to the boat with the Ronco catalog in hand to figure out what the biggest tank I can fit under the v-birth. All in all, it will be a very simple system. Manual toilet (she said the Raritan PHC would have been here recommendation) to a Y valve diverting the waste either directly overboard or into the tank. A 1" vent, as far forward as I can get it. A pump out and potentially, a seperate fitting on the tank for a manual overboard tank drain with a manual pump. The project moves on.

The Raritan hose is more expensive and more flexible. �I don't know if it is easier to install or more durable. � I'd like to hear Peggy's recommendations. �I'm not replacing the tank but am replacing thru hulls in the bow, so hoses need to be changed and could be reconfigured. �I know I want to move the discharge loop.
