We have very bad bathroom odors from the toilet, shower room with empty tanks, or partly filled tanks, while moving.We keep water in the toilet and put a one quart ziplock bag filled with water over the shower drain, but still have the odor while moving.Any ideas?
I have louvered rain covers over all my vents so I can safely leave the vents open somewhat while travelling down the road. My recollection is that the ceiling vents all have the open portion to the rear as do the rain covers. This mean the airflow over the top is forced to take a longer path over the vents which increases its speed. We all know from high school physics that Bernoulli's Principle indicates that causes a lower pressure in that airstream (why an airplane wing has lift). That should result in drawing air out of the camper, not sucking it into the camper. We've never really had any problems from bad odors in the bathroom as long as we are very careful about keeping deodorant in the tank and making sure we have a water seal in the commode.Jerry
