Best Sanitary Hose

[yvella]

Grettings All getting ready to replace all sanitary hose on boat. Would like to ask what manufacturer has the best hose being it's a big job for myself any way want to at least get everyones input. Again thanks.

FWIW - The Bellowflex exhaust hose that Hatt used OEM for waste hose lasted 30 years on our 53 MY until I decided to be "Proactive" and replace it with white sanitation hose, even though there was no problem with the Bellowflex The white "sanitation hose" lasted 2 years before permeating/smelling. I then replaced all the white sanitation hose with the OEM type exhaust hose.

The PO replaced all hoses so it has permiated to point hose was white now yellow and lil well smelling. Thanks for reply Mike. I have read some past threads and not looking forwards to the task but has to be done.

The previous owner installed shields. Seems very easy to get in these parts. Not sure how good it is in comparison with other brands.

We use white vinegar to keep the buildup down. Seems to be a cheap way to maintain the lines.

Use a table spoon of Noflex Digestor per week in each toilet. There will be zero/nada/no smell what so ever. This stuff works.

To reiterate what I said earlier in clearer terms...the best sanitation hose ISN"T "sanitation hose," it's exhaust hose. Of course, sanitation hose IS cheaper and easier to work. It just doesn't last NEARLY as long - in our case, by a factor of 15X. Frankly it's an excellent example of "you get what you pay for."

Of course, if the no flex digester can do as advertised - we have a couple of bottles but I've not yet actually tried it - then the hose quality may not really matter and using it is much cheaper than replacing hose!

My OEM hose will be 40 years old next year and has absolutely no odor. The water heater is still working too. Amazing.

But the best thing still is replace as much as possible with PVC.

I too have been using the Noflex and it does seem to work well. The biggest problem I use to have was after pumping out and the tank sat during the week first few flushes were BAD. This no longer is a problem maybe just a hint so I feel it is cleaning the bottom of the tank I also put some in the bowl and let it sit and it does a nice job of cleaning the bowl on my Raritan Atlantes

Mike, to let you how well it works I will tell you a quick story. The pick up tube on a friends holding tank broke off last month. We tried to remove the fitting on top of the tank. When we did the whole plate broke away from the top of the tank. The smell was horrendous. Brought tears to our eyes. We sealed it up. We poured 1/2 a bottle of the Noflex in the tank and left for a week. We returned with all the parts to remove and fix the tank. When we removed the plate to suck out the waste we could not believe it. There was zero smell even inches away. Try it you will like it.

Yeah - wish I had left mine alone...

Great feed back I have finished a list of material the hard pipe PVC AND flex hose probably what i will do. And the norflex is a product i will try to purchase ASAP.

I like the idea of using schedule 40 PVC since I am so comfortable using in houses. Why then is it not a boating industry standard? Could it be the vibrations, flexing and movement of the interior structures that might cause it to break? Would schedule 80 PVC be safer to use? It certainly is much cheaper to use the rigid pipe.

Would a marine surveyor fault a vessel that was using rigid PVC instead of flexible hose?

 

[Walter P]

I'd like to know if the PVC is officially OK to use as well. Many years ago I used it on my very first Hatteras and it worked very well. A few years later when I sold the boat the buyer's surveyor noted it as an attribute. It was a bit of a chore to install but it was worth the effort.

There might be a cheaper solution for Noflex Digestor. It contains the same 'active ingredient' as Oxyclean powder, sodium carbonate peroxyhydrate in about the same concentration.

The Noflex does have small amounts of detergents and seems to be buffered with sodium carbonate. I'm thinking of giving it a try after my next pumpout.

Will a spoonful of noflex in each toilet harm anything like seals, vacuflush parts etc. Bob, are you suggesting that Oxyclean should do the same job? Why don't you try it and let us know how it worked out for you. It would be too good to be true, but you're the chemist... Thanks

Good question Walt. Does anyone have long term experience with Noflex in a Vacuflush system? The active ingredient is an oxidizing agent, just weaker than bleach.

BumpAnd any input on use with a Electroscan?

I had a sailboat that the forward head was done with exhaust hose that had no problem, the aft head in the master had the flex hose and they smelled very bad. I replaced with the exhaust hose and never had any problem with smell. We lived aboard and the heads got a lot of use. The exhaust hose was not easy to work with but with a heat gun you could get it to bend the way you needed it.

I've used it for two years every week. No issues and no smell. Not sure if that is long enough to determine if there was any harm to the systems.
