odor from waste hose

[mavasu]

I have a leopard 40 catamaran.
On port the 2 inch diameter hose which empties the holding tank goes straight down.

On starboard unfortunately the hose does not go perfectly fair to the through hull and there is a sag in the hose with pooling to be sure.
The hose because of structure CANNOT be repositionned.The smell is notable on starboard.
Is it true that saran wrap on the hose could reduce the smell?
Read your book.Outstanding.

Thank you for your comments.

Yes, but end your problem and install new hose.

Do-it-once, do-it-right.

Hi Steve,
Here's my rant...We've been in our home 30+ years,,,no smell. Our parents homes 60-70+ years,,,no smell. Yet the boating community finds it acceptable to have poorly designed systems with inferior products that have to be changed routinely in inaccessible places.

I feel better.

And good luck geting 2 inch sanitation hose, if it is really 2 inch. My Jeanneau has 2 inch hose and it is impossible to find. My holding tanks are emptied by gravity. Good system, but that means the waste sits in the section of the hose between the holding tank and the thru hull valve. Eventually the hose will permeate and I'll have to replace. Looks like my only source will be to order the hose from Jeanneau

If we could use sewer pipe in our boats we would not have these odor problems either.

Is it possible to use PVC pipe in low spot/s?

You should also consider rinsing out the system with fresh water when leaving. Then give it a dose of Odorlos for the last flush.

Saran Wrap can help

It must be the Saran brand, nothing else. And that entire section of hose--not just the "trap"--must wrapped in it and sealed at each end. But I'll bet real money that you and I can find a way to re-route the hose instead. It may require a little surgery to the tank...but a permanent solution, even one that requires a bit work, is preferable to new "band aids" every few months...'cuz that's what Saran wrap is: a "band aid" that can let an owner put off replacing hoses till the end of the season. If you'd like to explore the possibilities, send me an email.

Hose sizes are always determined by the INNER diameter...fittings sizes are always the outer diameter. That's because hose and fittings wall thicknesses can vary by as much as half an inch...so I'm pretty sure that your "2 inch" tank discharge hose is actually 1.5", 'cuz that's the standard size for all tank fittings, thru-hulls etc. UNLESS....

If the boat was built in Europe, all the hoses and fittings could be metric (which means that the hose on the Jeanneau isn't really 2" either, that's just the closest size...maybe)...which makes find replacements in the US for any of 'em a real challenge.

You should also consider rinsing out the system with fresh water when leaving. Then give it a dose of Odorlos for the last flush.

The hose in question is the TANK discharge line...so to do what you suggest would require thoroughly flushing out the tank and discharge plumbing each time the tank is dumped at sea (he did say "thru-hull," not pumpout fitting).

Y'all gotta learn to read the questions more carefully!

And I just looked on the Trident website. There is now a 48 mm hose which is the equal to 1 7/8's, in both the 101 and 102. I'll have to remeasure as I thought the fittings were 50 mm.

That's a new size...

And good news for a lot of Beneteau, Jeanneau and other owners of "metric boats!" Glad you saw it and let us know!

I'm pretty sure that rident will send you a short piece to check on a fitting if you call and ask 'em. Phone number is on their homepage. Here's a link to the sanitation hose page... Trident Marine: Sanitation Hose You can get to the home page and phon # from there.

here's a thought , plumb around the bend using ABS and connect your hose frome there, not sure I have a good picture of your situation but ABS is what is used on most houses, stays fairly flexible, doesn't tend to crack, is completely non permeable, and there are fittings available to get from hose to through hull. I've been told it's not good to plumb your whole system in it, but a short section shouldn't hurt
