Which sanitation hose to buy?

We are replacing our sanitation hoses-we need about 50 feet because we have two heads (cat sailboat) There is a new, very expensive hose from shields that has a lifetime warranty against permeation of odors, but it will cost about 500$. Seems like a ton of money for something so invisible. Does anyone know if it is worth the money? Trident sells one for less-does it work as well to eliminate the stnech?

Lifetime hose? This I gotta see! I'd pay lots for it, too!
Your local ITT agent should be able to source some very good Shields hose that they have branded for themselves. However: my personal thoughts: any of the decent butyl-lined sanhoses that Hoses Technology (5 year guarantee) Vetus (dunno how long) and other people do should be fine for a modest [read: "realistic"]budget. All you're paying for is the absence of that unique, special yacht-heads smell.
Any good food-grade butyl-lined hose will work, I guess.
Good preventative maintenance also works: replacing low cost outlet hoses regularly when you overhaul is always a way to keep your waste system in 100A1 condition.

SeaLand OdorSafe white sanitation hose has a really good rep. It's such a big, nasty job to change sanitation hose out on a boat that spending more for hose that lasts longer without smelling bad makes sense. I've had it on my boat for six years with no odor problems whatsoever.

The builder of our own boat always uses a heavy industrial hose for the sanitation hose - I don't know the product name, however. Industrial hose is made for services much more trying than handling sewage without permiation so a visit to a good industrial hose specialist might provide an alternative (albeit a possibly more expensive one, I don't know). In our own case we have gone near on 12 years and the hose is still fine - we do though, always make a point of flushing the hose clear after use of the toilet and if the boat is left for more than a couple of days we flush out the discharge side with fresh water.

If ones boat is rigid enough, and any competently built cruising boat should be, then rigid PVC (even going to schedule 80) is the best solution by far, is easy to install with a wide range of fittings and valves and is what I am used to seeing in quality vessels. When the time comes to replace our own hose that is what I will be going for.

Or some other such series 40 or whatever.
I replaced all my hoses a 8 years ago and the name TigerFlex stuck in my mind.

Still going strong it is.

Any European or N. American SMOOTH bored hosed, labeled “Sanitation” should provide decent performance. I’ve happily used both Shields & Trident products.

Raritan: Raritan Engineering | Sanitation Hose
