Odor coming from drains in bathroom
My wife and I purchased and Columbus 340RK new in 2015. We love the trailer, the layout, the way it tows and its looks. However from day one when you turn on water in the sink or shower a fowl odor comes out of the drains. I put an inline trap seeing there wasn't one under the sink. This didn't much if any. And yes we have put deodorizers in the gray water. So here's my request. I don't think the stick vent is connected to the roof, ours seems to just come down to a plug and not connect to the drains. If one the other owners with a Columbus 340RK could do me a favor it would be awesome. while on the port side of the unit with the side storage door open take a look at the sealing maybe a foot inside on the sealing should be the bottom of the stink pipe that goes up thru the wall to the roof of the unit. Mine doesn't seem to connect to anything.
