When I replace my holding tank I'm going to replace all hoses as well. I see several options available in 1 1/2" hose. I'm willing to pay more for the hose if the extra cost truly equals improved performed, especially for prevention of odor permeation. Any recommendations based on past experience?

Thanks everyone.
 
Looking into that, thre are definitely certain sections that could be done in PVC. There are a few that I don't think I can get to though. At this point, unless I can figure out how to get better access to those spots, I think I'll have to stick with flexible sanitation hose.
 
PVC sanitation hose like the one Sealand sells is the best type of flexible hose you can use.
 
the plumbing guy at hardware store said to glue PVC hose to white pvc fittings instead of clamps. Anyone know about this idea?
 
Does the plumbing guy at the hardware store own a boat? ;) ( I used to work at a hardware store... )

I wouldn't use glue for the simple reason that it is irreversible. That is why you use clamps; you can remove them, and the hose, at some point in the future. With glue, you will need to replace more than just the hose ( in 2 to 5 years ).

Even if he does own a boat, that doesn't qualify him to give boat plumbing advice.

I would use hose clamps, not glue. I would be concerned with vibration cracking the PVC over time. I would also be concerned that when you slip a hose over a section of PVC pipe, you create a ridge that can catch solids and that might lead to a blockage.
 
SeaLand makes a fitting for 1/5" pvc to 1.5" hose....glues to pvc then hose clamps over their fittings.......I have several of theses fittings in my fittings box, as I use them all the time when installing or changing out systems in boats
 
You could use Fernco fittings to clamp the PVC and not cause a ridge.

As far as the flex use SeaLand.

Double clamp every connection except the main holding tank outlet. Triple clamp that one!

At several dollars per foot, I did not want to buy a lot of extra hose so I pulled all mine out, measured, and went to the local marine retailer and bought the best they had. I only needed about twenty feet total and I couldn't have used more than a couple feet of pipe if I had wanted to. It's all curves.

I used new marine hose clamps, double clamped. They say it's best to install the clamps in opposite directions from each other.
 
No doubt SeaLand OdorSafe is the best. It is triple the cost and usually worth it. My VacuFlush based system also has a section or two of Shields HD VAC sanitation hose which has held up fine for years of daily use, though I have heard complaints about it from those with salt water systems and systems where the hose holds some "content" between flushings. The section I have of Shields gets freshwater flushed and vacated every time.

I did my front head this spring and used Sealand. I recall that 12' of it was in the low $100 range.
Good Luck

Sheilds also has a new hose called POLY X.

Lifetime warranty against smell.

Anyone here using it? Not cheap stuff.

I have to redo my lines this year, I need 1" and 1 1/2" hose, the Sealand Odor Safe only comes in 1 1/2"
 
I always add some extra hose because I dont try to reuse hose ends any longer. Rather than struggle with getting hoses of I cut the hose and peel off the stub. Gluing wont therefore cause any problems with refitting hose.
 
I remember somewhere on this site that some were recommending either using engine water hose or exhaust hose of the proper diameter that was just as if not more effective, longer lasting and a lot cheaper than marine grade sanitation hose. The word marine in the front of sanitation = Higher price....
 
I have used sanitation hose instead of exhaust hose with wire in it but not for exhaust applications and I dont think I would go the other way because of smell issues. Sanitation hose bends easier and seems to work well in suction applications and has no wire to rust.

Even HD and lowes sell sanitation hose now and I really wonder if there is any difference in brands.

Beware, it may look like sanitation hose, BUT its spa hose....and WILL NOT clamp down tight, not to mention control the odor

That's why you need to take any advice you get on a boating forum with a "grain of salt". In this case, a pound of salt.

The point of special hoses for marine sanitation systems is not just to keep the sewage where it belongs, but to reduce or eliminate odors.

Hoses do not wear out in sanitation applications, but they become "permeated" with odors. "Sanitation hose" is designed to resist odor permeation. Water hose or exhaust hose is not.

As much trouble as it is in most cases to replace sanitation hoses on a boat, it's just not worth it to try to save a few dollars by using a cheap substitute.
