sanitation hoses

Has anyone ever used a snake to clean out the salt build up inside hoses? I am replacing the aft head Y valve and can see about 1/2 to3/4 in build up inside the 1 1/2 in hose. The hose runs about 18/20 ft. to holding tank. I don't see it being a clean and mess free kind of job but easier than r/r with a new hose, or how about a chemical solution or just fresh water to disolve the crystals?

There is a mild acid available at your marine supply store for cleaning calcinization out of toilets that should do the job. Sorry, but I can't recall the name at the moment.*

I'll bet Peggy will pop in and tell us.*

In my experience from replacing old lengths of saniation hose with a lot of buildup inside, the stuff on the inside of the hose is like concrete.* All that would break it free was to whack the hose repeatedly and hard against the dock and then what came out were big chunks and slices of the stuff.* The sort of thing that if they were inside a hose in place on the boat would probably jam and clog it.* I think a snake would just slide on down through the hose and leave the buildup intact.* But I've never tried it.* If you do, let us know what happens.

The snake won't work.* *Sorry.**

Have you checked to see if the you have odor break thru on the hose?* Take a paper towel section and rub it along the outside of the hose, particularly along the low spots.* Smell the paper towel.* If*has any*odor replace all the hose before proceeding.

Once you fixed the problem you need to maintain your system to prevent this from happening again.

RE: sanitation hoses

Larry's right...test the hoses for odor permeation before doing anything more...and if they test positive, replace 'em. If they're more than 10 years old, replace 'em anyway...'cuz 10 years is the average useful life of ANY hose...after that they start to get hard, brittle and begin to crack.

Muriatic acid, available from any hardware store, will dissolve sea water mineral buildup in hoses. You may need more than one application.

Distilled white vinegar will also dissolve sea water minerals, but using it to dissolve a heavy buildup (that weekly doses of white vinegar could have prevented) will take so many applications that it's not worth the effort.

Or you could remove all the hoses and beat hell out of 'em on the dock, then put 'em back...but I'd replace 'em before I'd do that!

And btw...if your sanitation hoses have a lot of sea water mineral buildup in 'em, every other hose on the boat that carries sea water will be just about the same shape.

RE: sanitation hoses

If you decide to replace the hose, the gold standard for sanitation hose is Trident 101. There is a new hose on the market that I think is worth considering. It is sold by Raritan and it has a 5 Year warranty against odor permeation just like the Trident 101. The difference is that it is super flexible and should be easier to install. It's brand new on the market so it will be several years before we know if it is really as odor resistant as the Trident. It looked good to me at the Miami Boat Show last month and I'll be stocking it in my stores. http://www.raritaneng.com/products/h.../saniflex.html

Carl, muriatic acid won't harm anything in the VacuFlush system or any other toilet...but why would you need it in a toilet that uses fresh water?* If you're thinking it'll clean the tank or tank monitor senders, it won't...'cuz that buildup is animal fats. You'll accomplish a lot more with detergent.

Hop...I'm not sure just how new Raritan's "new" hose really is. They don't make it, the mfr is in Italy (that's all I've been able to find out). It's also a dead ringer for Vetus "premium waste water" hose...
http://www.vetus-shop.com/vetus-wast...mm-p-1066.html
...and Vetus doesn't manufacture much if anything, they mostly private label stuff...so I strongly suspect that the Vetus and Raritan hoses are the same hose. Fwiw, it's also considerably more expensive than Trident...

The safer, and much more effective choice for what it looks like you want to achieve is to flush a solution of sodium hydroxide (lye) down the toilets and let it work on the fats and oils and deposits.

The only components that might be damaged are those made of aluminum.

RE: sanitation hoses

Unfortunately there is no single cure for the crud that builds up in blackwater systems. It takes an acid to remove the calcium and uric acid crystals and it takes a strong alkali to remove the fats and organic residues.

RE: sanitation hoses

For the last 14 year we have sprayed Clorox spray down the toilet on a regular bases to clean the hoses and smelling fresh, but we do get pumped out every weeks so its not big deal if the kill bacteria/germs DEAD. **15 years on the same hoses with no smell, but we flush with fresh water, and once a weekly bases I flush the hoses clean with Clorox spary which is pump out the next day.***

The best is to conver to fresh water as its not that expensive/hard as you can use a regular domestic water pump that is connect to the toiltet electric button with a one way valve to present back flow.* Again make sure you flush**thoroughly.* ***

RE: sanitation hoses

The build-up is fairly even all the way around the hose, although I can only see a short way in. I'm assuming it continues through out the length of the hose.

RE: sanitation hoses

Steve, could you replace your long run with PVC pipe? A lot cheaper than hose.

RE: sanitation hoses

Not and keep it under the floorboards in the engine room. I wish I could, it would save me money I'd rather spend on something I could actually see or use. Thanks for the idea though.

*I might guess that you have 2 problems....salt flush exclusively and too long of a run for a pump flush.

Better use that flush treatment regularly if you go back to the same setup.

My boat had HUGE sanitation hose*issues so I got rid of the sal****er and hand pumps. On the one head...I just removed the hand pump and used an elbow to let it fall into a hose leading to a cheap macerator pump. Now I can use inexpensive vinyl hose to the holding tank*versus expensive sasnitation hose (because nothing really lays in it)...plus guests like the push button flush versus the standard pump flush.

RE: sanitation hoses

Unless your hoses routinely reach temperatures above 170*F or so the chances of the buildup being salt are virtually nil.

*Waste doesn't have to lay in a hose to permeate it...and you will find out just how quickly vinyl hose absorbs waste that passes through it.* When it does, bite the bullet and replace it with Trident 101 sanitation hose...it's been on the market for nearly 20 years without a single reported odor permeation failure, so in the end it will actually cost you LESS to re-hose with it once compared to replacing cheap water hose every couple of years.

And if when you sell the boat, also replace that jury-rigged toilet with a real one before you put it on the market...'cuz any moderately knowledgeable buyer who sees something like that on boat the size of yours will wonder what else you jury rigged cheap that he can't see and walk away.

RE: sanitation hoses

not sure there's more of a chemical reaction than straight salt build up or not.

*I bet it will go a lot longer than you "guess".

Jury rigged???* I would say that most boat head systems are jury rigged or a flat out a disaster from the factory WITH the manufacturers recommendations.

Mine is simple, inexpensive, easy to repair, etc...etc...hard to say that about MOST marine toilets.

30 year old trawlers usually have a lot more to worry about than that piece of hose. Bought mine with "approved systems that were failed in no time" that's why I designed a "better" system...not one to make someone some money.

Don't call my advice "jury rigged" and I woun't attack your advice on "merchandise".

*We used it, it permeated in about a year, we replaced the run with PVC.* So that's one failure that I know of directly.* Not saying its bad stuff, only that it is not totally permeation-proof.
