It stinks in here

[chev]

2008 Beaver Patriot Thunder......when the holding tanks get about 1/2 full the sewer odor is overwhelming.............found one leak in the line, air leak that is, in the 1/2 bath slide out...........but no matter what we do, it stinks.......there has to be a design flaw that others have experienced.......help, I cannot continue blaming the dogs........

Make sure your vent isn't obstructed and you could try a vent 'helper'. And are you using the correct treatment in the holding tank? Some say they are deodorizers and some say they break down waste. Break down the waste and try something like lemon oil (Lysol with lemon) as a deodorizer.

Try Beano, eat less asparagus, uummm, put Vick's under your nose.

Good luck with that...

A couple of thoughts come to mind.

The vent pipe was supposed to be set into the tank, barely protruding into the tank. It has happened that the pipe slips down into the tank, although 1/2 way seems a bit extreme. If that happened, when the tank filled 1/2 full, the vent pipe would be submerged and unable to vent the fumes.

The second thought. This one happened to me. The stink was overwhelming when we drove. I checked the roof vent. It was O.K. I was baffled. Then one day I was searching around for something else, and I found an interior vent hidden behind my furnace, and... you guessed it.... it was not working. I replaced that cheater vent, and it's been O.K. ever since. Well, barely O.K. If we open our front windows, somehow it will cause a pressure drop inside the coach, and the fumes will come back at us from that cheater vent.

I don't understand why any manufacturer would choose to use an indoor vent for the plumbing system.

The other thing that causes a smell in my MH is the washing machine ( if you have one). If you don't use the washing machine often then the drain trap dries out and you now have a internal vent.
