Venting Indoors

[winesalot]

Hey folks. First post here and it's not a pleasant one.

The wife and I are building a 10,000 sqft steel building that will house a production winery, a tasting room, and a small 3 bedroom residence. We have the building weathered in so we moved our 34 ft Alpenlite 5th wheel in to the space where the residence will be built while we finish the business portion of the structure. I hooked the RV's sewer hose up to one of the toilet drains in the building and we are dumping black and gray water in to our building's septic system that way. All is well except we are struggling with the trailer's black water tank vent stinking up the buildings air space. Especially when the wind is blowing outside. I would love to hear some ideas on how to stop this as, in my wife's word, we are tired of living in what smells like a porta-potty. Any great ideas?

Rubber coupling with hose clamps to the roof vents, then pipe it up through the roof or to an existing vent line. May need an inline booster fan depending on the run, but probably not.

Good idea about adding a ducted vent. The vent pipe to the RV roof is probably a standard 1.5" waste line, so if you remove the cap it should be simple to connect a 1.5" light duty hose or pipe using a rubber union (it has screw clamps). Run the hose/pipe to any accessible outside access point.


A swimming pool vacuum hose or similar will do and is not expensive.

Good advice above. Of course you already made sure the black tank drain pipe is sealed to the toilet drain. Without the toilet in place, that is a direct opening to the septic tank.
