Replacement of all of my sanitary hoses is a project high on my "To Due List" prior to Spring launch.

It appears that Raritan Saniflex hoses are the most user friendly and still high quality with respect to impermabilty.
I understand that their are better hoses to fend off odors but are very stiff and extremely difficult to work in tight quarters.

I'm looking for recommendations, comments, lessons learned on sanitary hose upgrade/ replacement.

Thanks in advance.
Nick.

Head odor was a top priority 4 1/2 years ago when I bought #198. After a race recently, an experienced sailor mentioned he had never encountered a truly odor-free head on a boat before which suggests that the works. You can see a post describing some of what I did at the end of the discussion entitled "Head Tank upgrade & relocation?" but for the most part I followed what I learned from posts others have made on this site. I think the two best features of the system (regarding odor prevention) is using sch 40 PVC pipe bent with a heat gun and where hose was necessary, Poly X which claims it will not have any odor permeation for the life of the hose.

I've talked to other boat owners that said they replace their hoses every other year and that eliminates odor. I'm sure that method is fine if one can stick to the maintenance schedule instead of waiting until they're reminded that it is time.

Thanks for the feedback.
I plan on clearing out a few lines. Getting rid of the macerator pump & discharge lines. Maybe I'll have a bit more room and be able to use PVC elbows.
Regards.

Use Raritan Saniflex, you won't be able to install the other. The white hose gives a very good look. Don't go cheap here. I replaced the tank so the suction and discharge come out the top.

I have posted this before, but in my 26 years of owning Velera, I have never had a stink. I did replace the hoses with the expensive ones once a long time ago, just because the originals were cracked. The previousl owner told me to flush the head regularly with fresh water from the sinks (look at the plumbing and it should be obvious how to do this) rather than sea water intake. Alternating sea and fresh and always leaving fresh water in the system eliminates the stuff that grows in the hoses—primarily the intake, surprisingly. Also, complete flushing (at least 15 pumps for poo) and no paper in the head keeps the thing working and not jamming.
Care goes a long way to eliminating stink.

Ray,
Thanks for posting your comments.

My boat came from Maine last summer and is currently on the hard on the shores of Lake Superior in Bayfield, WS for the winter. The odor was getting a little better each time we pumped out, which was every time we were at the boat, even just for the weekend.
I also would add a product from Bio Kleen as directed after every pump out. I have also been spraying a product called "Sniper" on the hoses and closet walls ( portside closet, in the V Berth) that kills mold. My wife is more sensitive to any odor than I, so Happy Wife is Happy Sailing Life...

Since nothing really grows in the cold waters of Lake Superior, perhaps my boat will soon be as odor free as yours.
There is one hose that permeates odor when wiped down.

I read an article that someone wrapped their sanitary hoses with metal tape since they claimed metal won't permeate odors thru the hoses. I wonder if any fellow T37 sailors have had any luck with metal tape or know of a better product to add to the tank. I'm all ears..

There's a rats nest of hoses and a "Y" valve under my sink that I want to get rid of and help simplify my sanitary system.

Maybe I only need to replace a few hoses and not all of them ?..
Regards,
Nick.

Others may have more actual experience, but I have heard that once the old hoses get permeated with stink, you gotta replace them. I never had that problem because my previous owner was fastidious—lived on board for some time with no smell.
FWIW.

Here's a link to the Shields Poly-X sanitation hose that has a lifetime guarantee of no odor permeation; there is a sales video talking about the product.

https://www.jamestowndistributors.com/u ... ?pid=14411

As mentioned before, plumbing going to and from the tank has only a gradual slope toward the hanging locker which makes them a good candidate for schedule 40 PVC pipe. It can be shaped without burning with a heat gun and patience.

I agree with closing the raw water inlet / sink drain seacock and filling the sink with fresh water to rinse the system. I do that when leaving the boat to avoid the smell of stale Bay water sitting in the bowl for days...

We fought the smell for months after purchasing our boat. We replace all of the hoses and still had an issue. It turned out that the vent hose was plugged at the thru hull. There are little screens that keep the critters out and are easily plugged. I think Zach from Holiday replaced his with a regular thru hull and had good results. Proper ventilation is crucial to letting the bacteria do its thing. Also make sure the vent hose doesn't have any low spots that could trap water and stop the ventilation. Good luck.

That's correct. Those little screens were clogged pretty much completely. I'm surprised the whole system never imploded during a pump out. We used to also get smells sometimes. I installed a regular plastic thru hull there. On the boat as I type in Boot Key Harbor currently. Our weekly pump out is tomorrow (meaning ye ol' tank is full of poop), and no smells other that the eggplant lasagna Lindy is making in the galley! Smile
