Bounder Smell When Flushing
Wanted to share this just in case it may help someone else. I have a 2018 Fleetwood Bounder 35K with bath and a half. Bought used last summer. Since we've had it, there was a smell "some of the time" in the rear of the coach when you flush either toilet. It does have a vacuum flush system. Really spent some time trying to figure it out this weekend. Visually confirmed no leakage anywhere down stream of vacuum pump. Vacuum holds great on toilets and upstream of pump. What we noticed this weekend is smell is only when rear AC is running (already getting warm in Houston). Anyway, I noticed a hole in the side of the AC "wall" on the suction side of the coils where a wire goes through. Stuffed a rag in it, and bingo, no smell when flushing. Investigated further and found vent pipe through roof of rig isn't sealed around the actual vent pipe and the cap that seals it to the roof. Smell was going up vent and being sucked back down between vent pipe and cap going back down the roof filling the void with the "smell" and then the AC pulled it in. Even with clean filters. Anyway, thought I would pust just in case it may help someone else out.
