1.5" Sanitary hose

[SeaGator]

I'm looking for an affordable option for 1.5" sanitary hose for two VacuFlush systems other than the Dometic, Raritan and Trident green line hose. Has anyone had success with Shields Trident 148 Series Sanitation Hose VAC Extra Heavy Duty or Breling Vac Heavy Duty Marine Sanitation Hose?

IMO "affordable" isn't the best goal, in this case. Raritan Sani-Flex is your answer. Unless you're doing miles of it, the difference in cost won't matter when it comes to ease of installation (it bends nicely) and longevity.

Buy once cry once.

Unless you are doing this as part of a plan to offer for sale or to complete a sale I wouldn't cheap out on the hose. If you don't need bends I would look at using PVC pipe and fittings before the cheap hose. You don't want to do a sewer project twice.

Agree with both previous posters, it's short term thinking to cheap out on sewer hoses on a boat. Do it once, do it right.

Above are so true! The hardest part is wrestling out the old hoses.
Raritan Sani-Flex is the best, most flexible choice.

I have had good luck with Vetus.

I put in 148 pvc hose when first replacing my heads. Within 2 years replaced it with SaniFlex hose due to smell permeation. Defender had a decent price.

Saniflex hose is way to go. Somethings are not worth saving money on

As others have said, try to use black pvc where it makes sense, resulting in the sani-hose that much shorter, easier to change, and much less costly. With two heads, I have four short pieces (about a total of 10ft of hose) to replace at both ends of the pvc (head on one end, holding tank on the other). Having mostly PVC changes your mood/enthusiasm when it comes time to change the hoses.

PVC comes in black? I think of black as ABS.

Yep, I stand corrected. I installed black abs on my last boat. The current one already had white pvc installed.

If you are going to use hose then the only one I would use is SaniFlex. It is easy to install and will last without permeating. It is not a good idea to cheap out on sanitation hose because the job can be a nasty one and you don’t want to have to do it again.

Yes, technically you are correct when it comes to building supplies. Typically the color black denotes ABS pipe. However, I have noticed recently at Home Depot. They are starting to sell black PVC for sink drain connections and P traps. I don’t think you can find this commercially available for any other type of project yet.

I agree with installing the PVC where you can for longer stretches. I used a heat gun for bends and converted to the Raritan hose for the final connections. One advantage of the PVC pipe is that it does not sag like hose will. I installed it over 10 years ago and have never had any issues with it.

Having recently replaced both heads and all the blackwater hose on my boat - price is the LAST thing I would worry about. Buy the best.

Boy, you are surely correct about that.

As everyone else has mentioned, if you do not go with one of the better hoses you will get order fairly quickly. On my last boat I used PVC and bent it using a heat gun with a garage door spring placed inside to help keep the shape of the pipe. Used a heat gun for heat. Sealand (Dometec?) makes the proper adapters to go from the PVC to hose. See the attached pictures of my install on my last boat. Very little hose used and a neat install.

@Duvie Very interesting - don’t want to hijack and mine is redone so I won’t be changing it out. I thought about doing this but was afraid at the unions “debris” might build up. Also wasn’t sure I could maintain the proper slope and support it, was told it could vibrate and crack if not well supported. Most of mine runs midships and only support above, not below or too the sides.

 

[Duvie]

@Pprior, keep in mind that these systems pump through the piping, so slope and minor transitions do not pose a problem as with domestic sanitary systems. Also, as I recall those Sealand adapters provided for a very smooth transition. The other thing I made sure to do when I was upgrading was to add 1 1/8th vents, port and starboard to provide air to the tank to promote the favorable bacteria. That upgrade significantly reduced holding tank odors.

I used environmental Marine for a complete refit and used their hose. Two years in. I'm happy so far. YachtFlex Sanitation Hose, 1½” | Environmental Marine | YACHTFLEX38 Yacht Flex Hose | 1-1/2"/38mm ID, White Extra-Premium Sanitation Hose

If tight under the floor then remember to attach a pull rope when pulling out the lovely old hose.
