Sanitation hose

It's the best that I know of. However, BoatFix only sells it in 50 foot rolls. It you don't need that much, you can probably sell what's left over right here on BoaterEd. We get a fair number if inquiries about it here.
 
What Jim meant is to use 1 1/2" rigid PVC pipe where possible. Rigid PVC pipe doesn't permeate the way hose does. Every 8 feet or so, you should add a rubber coupling to absorb the vibration so that the pipe doesn't crack.
 
Thanks for your help. I ordered the hose through BoatFix.

Vic,
What do you recommend for the rubber couplings and what is the proper method to attach them to the PVC pipe?

Thanks,
Steven
 
They're black rubber couplings, available at any Home Depot or Lowe's, in the plumbing department. They are maybe 4" long with a hose clamp at each end. The PVC pipe fits inside the black rubber coupling and you tighten the clamps. They're commonly called "FERNCO Couplings." Their primary application is to make repairs to existing vent and drain lines in your home. They're available in all different sizes, so be sure to get the correct size so that the pipe will fit inside - they're about $3.50 apiece in the 1 1/2" size. Measure the outside diameter of the pipe, and the inside diameter of the coupling, and be sure they're the same. One thing to note: the hose clamps that are included with them don't have stainless steel screws - the screws are galvanized steel and will eventually rust. So it'd be a good idea to replace them with clamps that do have stainless steel screws.
