Rockhill.. when you dump your tank and you smell an odor inside your rv....can you determine exactly where the odor is coming from? Not being facetious here, but it sounds like you may have a bad seal, gasket or maybe even a vent that's not working properly. Is it leaking odors from the base of the toilet, connections to the stinky slinky, drain valves.....??
Being connected to the sewer with your stinky slinky....the sewer odor may come back up the hose and into your tank....but from there (since the toilet has seals and gaskets), the odor should then go on up the vent. If, by chance, you have your fan reversed so that it is sucking air into the rv, you will definitely suck in the odors along with it. If your fan is blowing out, it can suck up odors from outside where the odors may be leaking from bad connection. Best to have the fans off when dumping.
With a normally operating system, you should not get any odors from your tanks.
A word to the wise, when traveling... dump your tanks (black and gray) and then put about 5 gallons of clean water back into them. Add to that water one cup of detergent (I use liquid Oxy-Clean...others use Dawn...or..?) and drive to your next destination. The sloshing of the soapy water will loosen and remove and residual stuff that may be hanging around inside your tanks. At the destination, dump your tanks and put fresh water back in them and use as you normally would. Repeat this procedure every time you travel. If the toilet is sealed as designed, odors will not penetrate into the rv and as an added benefit, your tank sensor will work as designed.
Another source of odors in the rv may be due to a faulty Air Admittance Valve (AAV) that is located on your sink drains (sometimes on the shower drain too). This small device can get stuck open and then allow gray tank odors to escape into the rv. They are easily replaced if needed.
I hope this information helps.
