It's the internet, that's how. This thread has been thoroughly derailed.
I'm moving, but I am going to consult a plumber as soon as I find one I can trust and try this out in my new place sometime in the future. I will make a new thread with results.

Hard on fans. Most homes only have 4 inch pipes max. The diameter and lenght alone will creates alot of pressure. It works, but in most cases you need much bigger fans to move the amout of air needed. Maybe use it as a last resort at best.

I've thought of this too. However what is sewage? I'm sure the definition varies from city to city, state to state. Who knows what nasty chemicals could be in there.
Also if something were to happen to your sewer line you could have a basement full of shit...no fun.

I would do it it sounds tits just be sure to guard against pests that may enter through the sewer hole
I have used this technique for years it works great but has limitations. First of all I'm in Canada and all houses use 4" even for the vent to roof pipe.
(newer homes, the older ones use 2")
The limitation is trying to cool a room with air movement only will only work with a maximum of 2000 Ws IF the fresh air intake can pick up cool air. That means the shady side of the house. Most of the vented air will go up and through the roof vents but even then you can still only smell shit if you stick your nose in the vent.
These days I mostly build closed rooms with air cooled lights and C02. I will still make a vent to sewer and use a small fan just enough to keep a slight negative pressure in the room to avoid smell leakage. My intake runs through a sound isolation box made of drywall and green glue. I use three furnace filters stacked with one at least a carbon filter in this box so my intake air is cleaned before entering the room.

How would this work for a small personal grow 2-3 plants max
a 400w hps in a 2x4x5 tent
exhaust through a carbon filter located in tent then run exhaust into 4 " sewer and use a backdraft preventer
would there be any oder problems for the neighbors or the sewer inspectors to smell ?

Dude, you are so right on. Don't let a little lack of knowlege on the subject prevent you from expressing an opinion. LOL I am not much of a plumber but I am a licensed one and I know a couple things. First one being that anyone sticking his head in a sewer pipe is not slowly drawing air air across his taste buds to more readily capture the essence of the lady two doors up that just took a potty break while watching Opra, Really dude I promise you this, you ain't going to be able to distinguish the smell of dank skunk grow once it has mixed with sewer fumes. Trust me on this one. I am really really sure of this. Plunbing traps prevent sewer gas from entering houses. PERIOD
They do not prevent gasses from flowing iether to your house or away from your house.
So what I am saying imho, is go for it!!!! Heard the arguments against it. They're bullshit. every one. not a logical argument in the bunch
Why do ya think they call it
"dope"

you know what i looked and uh, you seem like an expert.
an expert racist, ignorant, self absorbed, condescending prick.
no offence....
but i also looked and uh,
i didnt see any pics of any MJ plants? actually, i didn't see any useful posts at all....considering you have almost 400 of them thats pretty fuckin pathetic,
you really need to stop posting so much, especially when you're simply being a dickhead and not providing any useful information or knowledge....
and to the OP, this DEFINATLY will work. i hav seen it done....in fact there was a good thread on here by a user "Pullinweeds" and he vented into his sewer system, he had good pictures to show how he did it, and it was only a small setup like 2x 150 watt HPS or something, but it was tight,.
anyways goodluck dude.
