odors

we are having a problem with terrible odors when we use our fantastic fan and washer seems to be coming from under our cabinets in kitchen but cannot pin point the problem can anyone help thanks debby

Debby;

I suggest that you look at the possibility of a failed vacuum breaker in gray tank vent pipe for the kitchen sink (probably located under the sink). Your dealer should be able to confirm this for you. This is what you should be looking for Here

Another thing which will let odors in is if you drains are open, the sewer smell can leak back into the tanks. This would cause the smell in the coach. If you have your gray drain open while washing (so the water can drain) then the sewer smell feedback would be possible.

You won't get the smell coming back when washing if the traps are full of water.

That is true. But when the traps are not you will.

We had the same problem - trouble shot it by trying to completely fill the grey water tank from the kitchen sink. Found a crack in the inlet abs pipe that allowed water to leak out under the 5th wheel just forward of the front wheel on the door side (only when it was "overfilled"). Since that grey water can actually smell worse than the black water holding tank, those fumes were drawn out when we used the vent fans. We replaced the broken pipe, and no more odors!!! Nothing a few $$$$$ couldn't fix!! Good luck with the problem.

Under the sink in ours is a vent tube for the Kitchen sink. It is to the left on a short stub. I ended up putting a plastic bag held by a rubber on the top of the stub. It is a sink vent to the grey tank.
