Holding tank odors

  1. We have an '07 Itasca Suncruiser 38T. I am having a hard time finding where the tank odors are getting into the coach. The conditions are as follows:
  2. If I run a slide in or out without the main door open, it smells.
  3. If I turn on one of the exhaust fans with the coach closed up, it smells.
  4. If I open a window going down the road, it smells.
  5. Sometimes just parked it gets in for no apparent reason.
I have done the following without success:
  1. I installed two of the venturi vanes on the roof vents.
  2. I have verified that all the "P" traps are full.
  3. The toilet valve is holding water.
  4. I have looked as best I can in the tank areas and cannot see any fluid leakage. Nothing leaks on the ground when it is parked at home for a while.
Because we do not see any fluid leakage, I think it must be a vent leak. On our older motorhome I went on the roof and secured a hairdryer to the vent. That was when I found a vent that was leaking. The tank areas on this one are are so hard to get to I would like to do the same trick but put some sort of liquid smoke in so I could see where it was coming from.

Any other ideas or solutions would be greatly appreciated.

Check the trap on the washer dryer. Run the machine for 1 minute or so and then rotate the dial to spin. You should be able to assure a good seal in the P trap on the W/D after it spins out.

We had that problem years ago in a Fleetwood Discovery and it was coming from the washer/dryer trap. Let us know what you find. Good luck.

Holding tank smells

Thank all of you for the responses. Upon further investigation, I found a very strong ammonia smell coming into the coach from below. It had to be the black water tank. I removed the water service panel to gain access to the black tank and found the big pipe from the toilet was leaking and splashing on top of the tank. There was no hose clamps on that one or the vent line to that tank.
I sent pictures to Winnebago and they said they did not use hose clamps on those "grommets". I cleaned up the mess and put clamps on both pipes. We'll see what happens when we take the next trip.
I'll report after that one in August.

We are two weeks into this trip since I found and installed clamps on the "grommets". So far no smell. I have opened windows going down the road, ran ceiling exhaust fans with coach closed, and ran slides in and out. Apparently the clamps fixed the stink. Yahoo!!! The only smell now is when someone is in the bathroom without the courtesy fan on.

on mine, I have found the vent pipe is inserted to far into the black water tank so I can only fill half way then it starts to stink. I think there are a lot of winnebagos with the vent pipe inserted to far. not worth fixing. I just dump at two lights. just another QC deal

So how did you determine that the vent pipe was in too far?

I have read abut this being a problem so I noticed that when my black tanks hits half full it stink and before half tank no smell what so ever and its has been this way since new, the first time I used it. I have tried all the chem additives nothing, except droping it at half full or about weekly.

We are getting a sewer smell in our coach; We turned the thing inside out trying to locate, where it was comming from.. Now it is a Winnebago, Ultimate advantage 2000 year, the most expansive coach winnebago built. Now as for the smell/stink. The vent for the tank that the sink drains into comes up under the sink then stops with a cap on it that has holes in it, to vent the tank;; all i can say is WINNEBAGO SHAME ON YOU;; While setting around the camp fire in the evening and telling of this no one would believe me tell I showed them. Now look we all cut corners;; but to vent the sewer into the motorhome, That is quite questionable; Don't you think ?? Life is good.. Some times stinkie;

That is not a vent, it is a vacuum breaker. You will also find one under the galley sink, not only on Winnebago coaches but on MOST RVs of any make. Unless it is broken or stuck somehow, the valve only lets air INTO the tank, not out. Without these vacuum breakers (there is different type on the back of the commode), when you dump your tanks all the liquid would be sucked out of the traps (sink, shower, washer, etc) which would then allow tank odors to come into the RV. The vacuum breakers do sometimes need to be replaced, but not terribly often. We still have the originals in place on our Ultimate Advantage. The only time we have ever had tank odors in the coach has been when we drove down the highway with the rear-most ceiling vent open ...it happens to be not far from the rooftop tank vent. If we leave that vent closed and open one further forward, we don't get any odors inside.

To clearify The under the sink vent.. It is open And vents out from the tank. Also the vents that are on the roof they are there to vent and to displace the air when draining the tanks. The vent under the sink is not ,never was a check/flapper valve; As it lets the oder flow out of it. I have taken the time to check it out. And I do not wish to dissagree with any one. Just the facts.. The next step would for any one who dissagree. come and look at it. PLEASE;; life is good most of the time;;
