|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.|
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.|
