Studor Vent for my conversion?

"Nope, a trap where the house line hooks into the main sewer line keeps out main line sewer gas from a home.

Those home vents are there 99% to prevent vacumn emptying home traps."

I agree with Gus on homes with a trap before a sewer line connect, but I always default my thinking to my situation on a septic tank.  No trap, and the tank is vented up through the stack to the roof.  Methane is technically odorless, propane is a close cousin and has an additive to make it smell, but sewer gas definitely has an perfume all it's own...

Brian,

I also have a septic tank with no primary trap. I've been on my roof many times and never once smelled sewer gas there although I have at least three vents there.

I opened the top of my tank years ago so it could be pumped out and discovered that it had a 2-3" layer of pink stuff on top that looked like plastic. It also was completely odorless, very much to my surprise. Nature is a wonderful thing!!

My theory on stinky bus tanks is that it is caused by the constant sloshing around. It never smells when it has been sitting a while.

I agree on the RV's and Maybe only in Cali but Arizona is the same as far as plumbing code supplements,.
Guys there are no traps between the house entrance and the street period. The only thing other than 4" pipe is a cleanout but no traps. Maybe where you guys are from. I am retired Building Contractor and no I don't know everything but I have installed many main entrance soil systems and that's the way it is done here. LOL

when fixtures are not in use the main soil stack vents the toilet and main lines and the sink fixtures have their own to vent them individually so the water will move out of the fixtures when used and as to not drain the P traps by Vacuum. LOL

I think the house traps are on the house side of the entrance, I've seen them on building shows on tv.
