We've been noticing an odor in the rig. Seems especially strong this summer. More than the past. Especially when flushing the toilet. I had a hunch there was some type of vent pipe blockage.

This is the factory installed vent pipe cover. Really just designed to keep the rain out. |

Here is what I found under the cover......after I killed a hundred or so Yellow Jackets. |

You can see they had the vent pipe almost completely blocked off. Only about 1/2 inch left for the air to escape. |

I found this product at Amazon. https://www.amazon.com/360-Siphon-RV-Fume-Extractor/dp/B001FC7DUC
It is designed to suck or siphon out the sewer gasses without any power or wind or fans. |

Here it is all installed & ready for action. Hopefully this solves BOTH the odor and insect problems. |
