CD25D Head hose

Post by Robert Pierce »

I need to replace the head hose on a CD25D. Does anyone know what type of hose and the diameter? The boat is on Nantucket Island and I would like to pick up the hose before going to the Island (would be nice to have a working head for the return trip).

Thanks

Robert,

1 and 1/2" is pretty standard for the waste line to the overboard discharge or to the holding tank. I would recommend standard Sanitary hose, don't go to the new exotic PVC hoses(Trident or OrdorSafe), they are too stiff and are very expensive! I just replaced all head hoses(and the head too!) on Hanalei and used the standard hose, everything now works fine and all is sweet smelling!

I replaced the head hose on board Rhapsody shortly after purchase. The previous owner had removed the head and was using a porta-a-potty. I used the heavy duty stuff. It is stiff, but if allowed to sit in the sun and heat up it was fairly easy to make the run. As I recall I needed about 20 feet and had some left over. I have no order problem, but then dont have the experience of the "lesser" hose for comparision.

As you know the run is fairly straight and fairly easy to complete.

Good luck,

You might eventually want to use rigid PVC for the length of run under the settee, with short hose connections at each end. Granted, this is a bigger job than just replacing the entire hose, but the end result is worth it. It makes a neat installation and will never be the source of odors. On my 25D, I ran the pipe in the lower inboard corner of the space rather than all the way outboard where the hose had been, so I had to hole-saw a new hole at each end, but everything lined up nicely and the pipe is hardly noticeable. There has to be one glued joint at mid-run since the pipe is longer than the space under the settee, and I needed hose-to-PVC adapters at each end, which I got from a SeaLand dealer.

Bruce - I also considered using rigid PVC to replace some or all of my sanitation hose. I was advised against it by naval architect friend of mine. He said that the use of PVC in a house is OK because the house does not move or flex. The movements and flexing of a boat would exert force on the PVC cemented joints, which he indicated would eventually fail. After a bit of debate (and a few beers) he admitted that PVC could be used for the longer runs with flexible hose couplings at potential stress points. Needless to say - I have not begun my replacement project and have not decided what I will use.

Good Luck,
Chris

I'm using 1 1/2" PVC pipe to replace all the sanitation hose I ripped out of our CD30. Hose flex couplings will be necessary as your friend admitted to. I'm using Trident premium sanitation hose for the couplings, each about 6" long. I recently built a new tapered 24 gallon holding tank to replace the original HDPE tank and the PVC pipe is the finishing touch on a dramatically improved sanitation system. Production manufacturers like Cape Dory could not use these benefits as they were to time consuming to produce and inefficent for production turnaround. Owners contemplating sanitation projects should consider options other than the standard systems for more durable and efficient systems.
