I told him how I read horror stories on here about the stench after a few days and he said it's NEVER been a problem. The chemicals and the ventilation prevent that. So out of precaution I will use the portapotties. However I would like to see more positive RV toilet usage posts on here. Anyone?
Nothing wrong with mixing it up between the portas and the RV.
Unless they've been cleaned really, really well, the waste tanks are going to contain odor whether they are empty or not. The idea is to keep the odor out of the living space. FWIW, we don't use chemicals but if there is something wrong, they would *help* mask the problem.
-When flushing, turn the vent fan off to avoid pulling odors from the tank.
-Just because it's bad in the bathroom, it doesn't mean it's from the black tank. Grey Water (shower and sinks) smells just as bad. There is probably a vacuum breaker located at the top/end of a pipe under the sink. It's intended to let air INTO the system but not OUT. Reach under the sink, unscrew it and make sure it is sealed- you may be venting nasty grey tank odors instead of black.
-The black tank vent pipe extends through the roof. It can become clogged or drop into the tank so that it doesn't clear the roof and vent outside like it should. We had a rig that had the vent pipe running exposed, through a closet. A coupler failed and let gasses into the bathroom.
-Keep a little water in the bowl. If it drains, there is a seal issue. Bad.
-Some toilets have an overflow tube. It's a clear chunk of plastic tubing on the outside rear of the toilet. If you've got one, it needs to have an "S" in it and the "S" needs to have some water in it.
On another note....beware the "Shit Cone". You can over conserve water when flushing, creating a mass directly under the toilet. The black tank is several feet long, but unless you're driving around, that stuff is going to stay right where you dropped it. Use enough water and try to minimize TP use (or pack the TP in a bag). I've never messed with it but some people will save graywater from dishwashing to use to flush the toilet (turn water pump off first). In any case, several days in, your black tank may appear full when it's really not. Put on a clothespin, grab a 3' chunk of dowel rod or broomhandle and shove it down the toilet, giving things a good stir, adding water if needed- it may save you a $60? dump fee
FYI, A typical black tank is 25 to 35 gallons (five to seven 5 gallon buckets). That's a lot of waste.
