We just purchased a used TT (made in 2020) and when it was delivered, the bathroom didn't smell. After 2-3 uses though, the bathroom started to reek of pee! We have cleaned the bathroom top to bottom daily and it seems to help for a short time, but it always comes back! The smell never fully goes away. We have emptied and flushed out the black tank, washed the walls, the floors and, of course, the toilet. We have owned RVs before that were older and have never had this issue. It is bad enough that the bedroom get filled with the smell as well. Any ideas?
This may sound a bit silly, but
how much water are you using when you flush and use the toilet? The reason I ask, is because the first travel trailer we had the kids were not fillig the bowl with water and just flushing for a few seconds each time they used the restroom and this caused a lot of odor. In short, I noticed whenever flushing the toilet the smell was
strong, really strong, practically unbearable, but after I dumped that time I started filling the Black water tank with about
5 gallons of water right off the bat. Then be sure to
fill the toilet part way with water when using and flush thoroughly (we use the packets to help with the smell as well, but w
hen we were not flushing with a lot of water, smell was an issue initially).
Ever since I started filling the tank with about 5 gallons, fill the toilet half way when using, and flushing thoroughly, no smells at all. More water = less smells in my experience. This was especially the situation when camping here in
Texas in the summer when it was
100 degrees plus outside and you leave your trailer with the A/C off for hours at a time while out hiking and what not. Also, just to mention, we only dump once we are about 2/3 full, and when we do I go ahead and fill it up to full with fresh water once I realize its at 2/3 full and then I dump to get everything flowing out well.
One last thing we started doing at the recommendation of a friend to keep the tank clean (and it works fantastic) is when we are heading home from a trip, I buy about
4 to 5 bags of ice and pour it down the toilet into the black tank before he hit the road, and when
we get near home I dump it at a local state park (by this time
it is melted and has been sloshing around for hours) and it really does a good job cleaning out the black tank and keeps the sensors working great.
Just my 2 cents on
what helped our TT stop smelling. Below are the type of drop in additives we use but they only work well when you got plenty of water in the tank, there ain't nothing worse then the bathroom smelling when out camping in my opinion.
