Lippert 360 Siphon RV Roof Vent Cap for Odor Prevention with Universal Fit, Built-in Bug Screen, Black Polycarbonate - 389380

Install is just as directions say. Easy to do. Made a HUGE difference!! No more odor wafting into the camper when we flush the toilet! Definitely recommend!

Works great

Must admit as in other reviews it's not heavy duty. I drove 400 miles after installing it's still there. It absolutely did away with smell from the black tank. Don't do like I did and glue the top piece on before putting it on. Makes getting at your screws lil more difficult. But for what this thing does it breaks I'll buy another for 20 bucks.

I have been on the fence installed these lippert 360 siphon vent on my rv for a little while now I have heard nothing but good things, how it suppose to take the unwanted smell out of your rv. Well, I don't know first hands because my rv is in storage now but next summer when we get it out again, this was a piece of cake installing them on the roof, I installed one for my grey and black water tanks.

I would highly recommend remember lacing all your rv roof vents with these. We have a 43ft 5th wheel with 5 vents. Everytime I would dump the black tank I would get a smell by out bedroom. Replaced all and no more smell. Great replacement

I installed a "wind-vane" style cap on my last RV, and my latest RV came with one installed. That style is better than just a cap, but not by much. My most recent RV bathroom had much worse odors.First, I inserted a pressure hose down the vent, and knocked loose any wasp nests, which there was at least one, which helped a little, but it was still bad. Then I installed this cap, and it's made a major difference. It still smells in the bathroom, but I don't feel like I'm inhaling poison anymore, and my air-filter can mostly keep up now.I think I also need to uninstall, seal, and re-install the toilet, but at least the bathroom is manageable.I am concerned about the durability issues mentioned in many reviews, however I don't move my RV often, and I did try to make sure to glue and seal it well.

Works as well as my old Camco cyclone, but for the price it should have came with screws and sealer.

While inspecting the roof top My RV, a Sunseeker 2250 I noticed the cover had come off. Possibly from low lying branches on the side roads or in a camp ground. I searched online and even though I only needed the top vent part I had to buy the whole vent, bummer. But I put the top on to replace the missing piece and it fit perfectly.
