sometime sewer smell

[donnary]

I have a 2005 Jayco and im trying to check the roof vents for wasp nests etc.,but they have caps on them ,and the legs of the caps are imbedded in the caulk that surround the vent pipe. Can i just pull these off and reseal with lap seal? Also where is the check valve for the black tank vent located? thanx.

You don't say where you are getting the smell but something to check for. On our last coach they did not extend the vent pipes high enough to clear the roof so fumes would get into the ceiling. I only found this when I removed the roof vent caps in order to install Cyclone vents. I highly recommend the cyclone type vent caps. Since installing them we rarely even have to use chemicals in the tank.

Most often sewer odors are pulled into the coach by an open roof-vent causing slightly negative pressure inside. Flush the stool and odors are sucked up from the tank. If you notice odors at other times, in can be as Brian said; or, it may be as simple as needing to use more flushing water to keep any solids in the tank completely covered.

install a cyclone they realy work

Be sure to run a little water into all the drains, as sometime negative pressure will break the water seal, or if its a drain that hasn't been used for awhile it could be evaporation from the trap that causes a problem.

Besides what others have said, you might replace the vent(s) that should be under your bath and kitchen sink as they can leak gas from your gray water tank. Had a similiar problem as you and after replacing both,(about $7 ea), the smell went away. We got ours @ Lowes. They just screw on and off.

I agree with JC2, we had the same problem in a unit we previously owned. Took a long time to figure it out, including installing a cyclone, but after we changed the "sticking open vent" under the sink the problem disappeared.

We had an odor smell like sewer and found that the trap for the washer dryer was the cause as we had not used it for a long time and no water in the trap.

Occasionally if the wind is right (errr wrong) the odor will blow back through an open roof air vent which is just downstream from the tank vent. Since it has only happened a very few times, haven't done anything about it except close the air vent hatch.

And you were originally blaming Roxie or ? Shame Shame

Does anyone have pics of the vent? Fleetwood is telling me the vent is inline. The pic above is an end cap.

Uh.. guys/gals... the original poster asked how to remove the vents on the roof....

I'd like to know the same as well - I occasionally get a bad odor in the closet in the bathroom where the vent pipe is. My vent is like his, 3 posts or so that mount and are covered by caulking.. not just a cap that pops off from what I can tell.

What about the smell only becoming noticeable when driving down the road? In 4 years of having our coach, we've never had an issue. But, enroute coming back from The Rally in KY last month, the smell crept in the coach. I thought it was due to no place to dump at The Rally & we had to hit the road w/full grey/black tanks until we could get to a Love's. But now, it seems to waft in anytime we're on the road, even AFTER tanks have been dumped. The smell is strongest in the hallway at the bathroom & towards the bedroom.
