When we converted our 9, we installed P-traps. They take up precious space in the luggage bays and kitchen cabinets. They sometimes partially empty in the rocking motion of road travel, and they occasionally evaporate if coach isn't used for a week or more. I'd like to eliminate p-traps in my 102 conversion. Trap Guard (Proset) and Sure Seal (RectorSeal) both have solutions. I'm leaning towards Trap Guard. They actually make a version that will fit the 3" toilet opening which would eliminate odors coming up from black tank when flushing etc. Any thoughts?

Is it just a flapper type thing? If so, I'm somewhat suspicious that small particles will begin to collect on the edge with time, and begin to allow gases to escape. The video shows it working nicely with clean water, but what goes down my drain isn't always clean water.
I'd love to eliminate P-traps, but I'm not convinced.
You do it first, and let us know :)
If you look at the Internet site it states that it is for a floor drain not a replacement for a P-trap.
Sounds like a device like that could be a good idea.
Not for use on a toilet as Scott was wondering. Debris and paper WILL collect at the rim and at the flapper and clog it open. I have seen somebody else try this, resulting in a resounding failure, and a messy, smelly clean up. These have been around for years and years with the old ones made of brass. They only work well on clean water no gravel or sand like most guys are washing down their shop floors.

How about a vent line from the tank to the roof and use this ventfan? Could turn it on when using toilet
You could reduce the line after fan ant it probably still do the job as long you don't keep it turned on.

Course if the suction is too great, you may need to keep a pry bar in the bathroom handy.
I've been using a hepvo waterless trap for my shower for 7-8 years of part time use. It has not given me any problems at all. They only come in 1 1/2" so it is not suitable for toilet use. www.hepvo.com (http://www.hepvo.com)
TrapGuard isn't a flapper. That's why I'm interested. They claim that the material is teflon slick so nothing will stick in it and cause issues supposedly. It's a memory curled piece of plastic that curls up when not in use. Different design altogether than a flapper.
Scott, it seems to me that if installed in place of the p-traps for sinks, bath, and shower (generally grey water) the Trap Guard would solve your problem. I'd not install the grate on the top however unless installed directly in the sinks and shower/bath drain. As for toilet, I don't know what kind you have. Most RV type are a straight drop and the water above the flapper/ball seals out odors. If it's like a house unit with a p-trap build in I'd think it not really needed as there is usually water in the bowl that would prevent odors. I know nothing and give that freely. Don
The issue he wants to deal with is the tank fumes coming out of the toilet when flushing.Personally, I'd use a roof vent and look how the new job johnnys are designed to keep fumes from coming into the user area when lid is up. I've looked them over and their design works.
Not sure about your idea, but what I did was use only 1 trap for shower, kit sink and bath sink. I think it is 1" but could check, and no problems so far.
It has potential for grey water alright, but the real problem is handling the toilet pipe. I don't know if they still make it, but there used to be a product called "Stinkerator" which was a low level fan that was in the vent pipe to create a slight vacuum in the system to keep the odors from coming out. I never got around to try it, does anybody use it?
Good info here. Really like the single trap for everything idea too. A negative pressure from a blank tank vent fan might work too...
