Smile Waste water tanks-

I purchased a new Montana 5th wheel 4 years ago. In the last 6 months the smell from the tanks got stronger inside the trailer. I started using more chemicals ,but that didnt seem to help either. This week I decided to replace the vent covers on the roof for better air flow. Well, I found the problem as soon as I lifted the cover.
My local native Wasps had build mud dobbler nests in the top of the pipes, and left about a 1/2 inch hole for the air to vent. Come to find out ,all my vents had the same problem. After cleaning those out , I could actually smell the odors from the tanks. I guess I will check those more often now. That will probably help the the drainage of the tanks also. Happy trails..
