Exhausting Into Sewer

don't be shy now-

sounds good. think worst case scenario.

from the start. if you were pressurizing the line you wouldn't have any gas backing into your lead, and the vent would be at vacuum all the time from the airflow to the lead. so, no problems flushing.

i would build a tree that had the fan at the top of it. use a fernco to couple. in the tree i would install a backflow valve commonly used for sump lines in case you did have a backup. you would imagine that would catch most waste in the event of backflow.

design the tree so it can be uncoupled at the bottom where it hooks to the lead. install a valve at the end of the lead under the couple for the tree. this would allow for isolation and removal if the need ever arose. a plastic 4" ball valve would probably be fine.

experimentation will dial the system in. the only real problem i foresee would be the vacuum at the house being so great that it would suck the traps dry. probably this wouldn't happen, but it would easily be solved with custom made, longer traps.

i would do it. the underground room could come in handy for all sorts of reasons.:)

Not shy, just had to eat some dinner.
I may have to retract my statement about anyone on this site being able to teach me anything about sewers or plumbing though.
Sounds like you know your shit and yes I do mean that literally LOL.
Honestly I think I would have to ponder that a few minutes to even totally understand WTF you're talkin about. Again lol
but thanks for the positive response. i think it's the second one I got here.
Didn't know so many people had such strong opinions about sewage.

OK, I gotcha now. hell yeah, that would work great. I don't think I could improve on that design.
At least for starters like you say..
Actually my more pressing issue at the moment is Henrietta
Poor little thing. What kind of a person would say something like that?
Oh I forgot.......................a fucking woman inspector!! What an asshole!!
She is an ugly little shit though. Henrietta that is.
Probably Stephanie too if I had to guess.
Odd why in nature the males are always so beautiful and the females so plain.
That's probably why Stephanie is such a BITCH
Must be tough goin through life ugly as a mud fence.
Not knowin shit

yeah, the room would be cool. My wife is actually the one who wants the hidden room. Been bugging me to build her one for years. She wants one that you enter through the bookshelves. Couldn't really see how I was going to work that through the building dept. though. Didn't spend any time thinking about it though either. I'm building a 600 sq. ft. studio for her at the moment. That's how this came about. Ran into the old septic tank in the front yard and between the pot and my wife's encouragement we came up with this plan. Probably not going to happen just this way but it was a very cool idea. I was going to install a hydraulic lift in the slab of the walk in closet for entry into it.
It would double as a safe room should the appocolypse happen. I'm not into that shit but WTF I was gonna get a really cool grow room out of it so WTF.
I've decided that it would be a lot easier to build a masonry room at the bottom of the hill and bury it. The inspector already agreed to it. I can build a 120 sq. ft. "temporary" shed without a permit. He, in his infinite wisdom has agreed that a masonry structure qualifies as "temporary". Only an inspector eh.
So anyway I am also building about 200 lf. of Keystone retaining wall with a burrito drain behind it and I'm thinking about exhausting into that.
Do ya think I would have to scrub that exhaust first or would the smell dissipate in your opinion.

Geez I hope I don't start a bunch of shit about burrito drains.

not sure what a burrito drain is-

sounds like a french drain though. like a long skinny grate poured flush to finish floor? or a weep tile? that would be a long perforated flexible pipe with or without a sock on it. if that is the case i would try and keep that storm water out of the sanitary (poop) system. installing a small storm system is easy to do and precast concrete structures (manholes) are cheap and readily available.

if you did have a french drain plumbed to the sanitary line, a p-trap made out of schedule 40 fittings and close nipples at the drain would prevent gas from exiting the drain.

but sounds like the logistics of the room are good. alot of people are probably building 2012 rooms so the inspector didn't even think twice.

Nice attitude bro. Would love to see pictures of this "build" of yours. Hopefully you can find another way to tortuously try to make something work the way it wasn't designed to. It seems you lack a basic understanding of physics.. most notably, fluid dynamics and airflow.

This seem to be off tangent now but if you bubbled the exhaust through water then fed it into the top of a sewer pipe you shouldn't have any problems as long as your sewers do not flood during storms.

To do that the exhaust would have to be pretty airtight and strong enough. Think of it like the air pump in a fish tank.

Any unwanted odours would still escape through rodding holes, manholes ect. And they will backup into your house and out the top of the soil stack.

you are forgeting one fundamental issue, have you ever been in the sewers, one day they are warm and calm, a week later they are freezing with severe winds down there, a bit like the ocean on a stormy night, airflow and fast water flow run side by side.
