My family recently went on our 2nd camping trip of the year and fourth overall in our 2007 Flagstaff 27BHSS. After arriving to the campground and setting up I was informed by my step daughter that there was a terrible smell in the bathroom. Upon entering the bathroom my initial thought was that a mouse or rat had gotten inside and died.
After further inspection I found the smell coming from the toilet area. I contacted my dealer for advice and was asked if I use chemicals and the RV toilet paper. I use Odorless chemicals and RV specific toilet paper. It was then recommended I empty the Black water to see if the smell goes away. Of coarse after just setting up camp I was not about to break camp to empty the Black water tank. I might have but the smell was isolated to the bathroom area. I then proceeded to fill the Black tank about 1/2 full of water and added another pouch of chemicals. This maybe helped a little.
Yesterday after breaking camp we stopped and emptied the holding tanks as usual. I then proceeded to flush the tank. I filled the tank about 1/2 full and added more chemicals. After returning to the storage facility I again emptied the Black water, filled slightly and added more chemicals, and then parked the trailer.
What is puzzling to me is that no matter how bad the smell is inside of the tank, how it could be getting into the trailer? My family and I have used the trailer three times prior to this without any noticeable tank smell.
I plan on checking the vent for the black tank of which I was told by my dealer that there is one on top of the trailer. I also plan on checking the routing of the bathtub drain to ensure that it is routed to the gray tank and not the black. I will also be adding a flush system.
Any advice or experiences would be appreciated.
