Cyclone Sewer Vent

Catalog Item # 31992

Never smell tank odors again!

Even a gentle breeze rotates the Cyclone 360° to follow the wind. It creates a powerful vortex that pulls odors up and away so they don't enter your RV living area. Low profile design. Attaches to any plumbing vent with no drilling into rooftop.

Item was to replace one lost to a tree branch. Have used cyclone sewer vents on my current and previous motor homes. Definately fu

When I run the air conditioner of our trailer for extended periods of time on hot days, a very strong poop smell comes out of the air conditioning unit. The smell starts gradually until it's fully emitting poop odours non stop unless you turn it off. It doesn't happen when the same fan is running - just the air conditioner. We've done everything! Ran hoses down each vent pipe. Took apart roof top unit to ensure nothing has died in there, poured cleaning products into septic tank....and more. Nothing is working and I'm getting so frustrated. Do you think this product could be the solution to my problem?
It sounds like the plumbing vent on the roof of your RV might be placed right next to your air conditioner. When a standard plumbing vent is placed next to a rooftop A/C it is not uncommon for the fumes to be sucked in by the A/C when turned on. A product like the Cyclone Sewer vent or 360 Siphon is helpful in redirecting the fumes away but also keeps the fumes from building in the holding tank as well.

Another thing to look at are your house batteries, 'boiled batteries' can cause a sulfur like smell.

This item will keep rain out in most cases. In cases of sideways rain, it is possible that some rain water can get in, but it is still very unlikely.
