New version of the RV 360 Vent Cap: the 360 Siphon

[Richard 34A]

There is a new version of the RV 360 sanitation vent, called the Siphon. It has a really low profile compared to the original RV 360 Rotating Vent Cap. The new version also has no moving parts.

Has anyone here tried installed the Siphon? I have two of the RV 360 Rotating versions but haven't installed them yet, (though I should have!) and if the new Siphon works as good as the original design, I would prefer that design due to the low height. After I bought them, I decided that it seems like the older style design would be great at catching the tree limbs so I never put them on.

Any feedback would be appreciated on both styles...

(Pricing is $24.77 per Siphon, listed at another website)

Richard,
I've had the 360 rotating on two rigs (starting 2001) never lost one or had any problem with them. They do their job!

Best,

The rotating model was designed to release objects that get snagged. I've had one on our black tank vent pipe for 4 years now. It works fine but the bushing that enables the unit to rotate is starting to stick a little from years of use.

The new model you refer to was probably designed to function without any moving parts in order to eliminate this problem. It also suggests that you don't really need a rotating vane to adequately draw air from the vent pipe.

At any rate, if it were me, I'd go with the model without moving parts. The only caveat is that this model has a screen to prevent insects from entering the pipe (???). Over time, the screen could conceivably become clogged with dirt which could impact its ability to function properly. You may want to check it out every few years when you're up on the roof.

A modern application of a very well established process:

This has worked for almost 300 years without the moving parts so the low profile one should be just fine.
