Sanitation Black water hose

Replace it with Triton hose. It takes the longest to get permeated with stank.

been there --- done that

my prayers are with you, and while doing the job,remember the third commandment :

Do you have Vacuflush?? if so the vacuum pump would cycle often it their was a leak in the hose. Vacuflush heads discharge with 1 1/2inch hose and some others use 1inch. If your head is 1inch and you have a hose adaptor right at the head brought up to 1 1/2inch with a short length of 1inch you can move the adaptor right up to the tank and run 1inch all the way. Good luck with the repair.

If the hoses smell bad, you can do a quick fix till you get around to doing the job...wrap the hoses in "Saran wrap" must be Saran, make sure it stcks well, heat gun helps...

Interesting trick, how many wraps does it take? Sometimes I do a delivery and the boat just wreaks so bad it's nauseating to sleep onboard.

Just a twice around does the job usually. It's a frustrating job, that Saran wrap just wants to stick to itself, if you can, put it on length wise, is easier.

It worked for me till I replaced 5 hoses with NO sags....

I wonder if cuts of shrink wrap and a heat gun would work, too? Myself, I can't even wrap a sandwich with that "clingy" saran wrap. Interesting that this would work since a lot of the hose would be behind bulkheads, etc and impossible to wrap.

Well, you have to realize that it is impossible to wrap it all, if you get most of it, then you are at least helping the situation.

Agreed! That smell is nauseating

One other thing that can create the smell, is the location of the vent to any partially open portlites, and a full holding tank will aslo help to keep sewage in some of the lines. As the head Lady Peggy Hall says, flush holding tanks monthly, how many do that ???

Does the head use fresh or sea water to flush? There's no sewage on earth that smells as bad as stagnent sea water in the summer heat. I've converted many heads to fresh water flush to eliminate this problem.

Is there standing water in the bowl after flushing? This water acts as a vapor barrier to stop sewage gas from coming back up the discharge hose from the holding tank. There may be a duckbill valve in the discharge outlet that is supposed to prevent the gasses from coming back but in most cases it is not a complete seal.

Just pour a cup of fresh water from the tap after flushing and it neutralizes the salt water algae smell.

before you tear up the boat and your hands and arms,i would clean out and flush the system w/ fresh water.....then i would figure out a way to temporary use fresh water to flush the heads....try this for a while,if it works, it will be well worth the effort......
