Most flexible odour resistant toilet hose

[Irish Rover]

The electric toilets on my boat use sea water. The existing inlet hose is a cheap type and I want to replace it with odour resistant hose. There are a couple of tight bends to negotiate so I'm looking for the most flexible non-kink hose I can find - 25mm. Any recommendations based on experience much appreciated and welcome.

I switched to Vetus loo hoses last year, expensive but very pleased with them but it would depend on how tight is tight.

25mm seems a tad small for an evacuation hose.

You might want to consider whether having some rigid fitting(s) - e.g. a 90 degree bend, or whatever - inserted into the pipe run might help negotiate the tight bends you mention.

The butyl sanitary hoses specifically for heads are good (which is what I assume the Vetus ones mentioned above are). They have a degree of wall flexibility which makes them much easier to get onto fittings than standard reinforced hose (a boon when you get up to 38mm ID) and resist odour permeation longer.

On the other hand, because for the extra thickness of the walls they have a greater external diameter (for a given ID) than standard reinforced hose, which actually restricts the tightness of the bends that can be achieved with them, making them difficult to route through some confined spaces/shapes.

Standard fit on most electric toilets.

Generally best avoided in toilet outlet hose.

The original poster did ask about sea water inlet hose.

I can imagine sea water in the inlet hose going slightly whiffy if the loo is not used for some time but I don't ever recall that sea water whiff permeating the inlet hose.

Vetus Sanitation Hose is however available in the smaller sizes and actually has quite a tight permissible bend radius



Do many people use this type of hose on the inlet?

Sea water intake hose.

I always use bog standard (excuse the pun) water hose for the inlet.

I have good quality jabsco inlet hose on the port side toilet and no pong, cheap hose on the starboard and definite pong especially after a week or so without use. Same Vetus disccharge hose on both. Hopefully changing the hose will solve the smell problem but, in any event, I'll be happier with good quality hose connected to the through hull.

This stuff isn't cheap but is very good / flexible. I've replaced both the inlet and outlet with it and it completely cured the heads odour problem

Raritan Saniflex (flexibility and permiation resistance) is by far the best in the US. Don't know about UK availability.

I do too, standard PVC for inlet and outlet, and have never had an odour from them.

Me too. Standard PVC hose. It's cheap and easy to fit and remove. Never had a smell. If the toilet is installed and maintained correctly it won't smell.

Wasn't he a genius really the guy who invented the odour resistant sanitation hose and conned hundreds of thousands of boat owners into paying crazy prices for it instead of using garden hose

Not really, there's far more money to be made by treating symptoms rather than the root cause!

I replaced the inlet hoses today. I have to admit I was surprised when I split the main intake hose from the seacock to the pump all 1.5 metres of it. It was clean as a whistle inside. I was expecting, at a minimum, a build up of the scum which adheres to the underwater parts of the hull. The Jabsco hose was a good bit less flexible but on the plus side it didn't kink like the garden hose I replaced and there is definitely a better flow to the bowl.
