Exhausting into sewage pipe?

yeah im a plumber too and i gotta agree , i wouldnt pump anything down the toilet . id just tie into a dry vent ( a vent that will never have water go through it ) around here the only wet vents allowed are vent for the toilet . they can have 1 sink drain used as a vent . other than that every other vent should be dry . and if your worried about your neighbor smelling ganja from the roof vent , i wouldnt . ive never smelled crap outside my house so why would i smell weed ?

Im tellin you Rocket check for access to this sewer pipe in your basement. Almost everybody has one and theyre very accessible, the pipe leads directly into the sewer too so you dont have to worry about anyone but the rats smelling your ganja man! Ive heard of lots of problems with venting thru those toilet ducts unless you tap into it right before it goes outside, even then you could run into problems. The sewer pipe in the basement is so simple and effective, all you do is remove the cap and hook up your exhuast to it. Thats it, no holes in walls, no cutting into existing ducting, just remove a cap with a monkey wrench. My buddy that used his added a backflow thingymabobber so when his fan wasnt running he didnt get any sewer smells coming back into the basement but thats super simple too. Check out that link on my previous post, it shows you exactly what pipe and how ta do it.

The access to the sewer in the basement, outside, ect. is called a clean-out. The backflow thingymabobber is called a backflow preventer chief, close .An inline damper could also prevent the fumes from entering the room. You could run a vent into the clean-out in theory. Is that what its designed for? Not really, but no hurt in givin it the college try. If a sewage back up would ever occur and your cleanout was open it would be the first opening the sewage would leak through. Don't forger SHIT happens and sewars DO backup. Wouldn't want your neighbors shit sitting in your room when you wake up.

If you're hell bent on running it through the sewer and cant run it through a dry vent i would HIGHLY suggest getting your sewer Cammed and rotor-rooted before forcing air into it. I would also put a General Flood Guard on the cleanout( you can find it at any plumbing supply house) this closes the cleanout in the case of a backup.

Trying this out should save a few headaches down the road.

Let me know how it works for ya Rocket, interesting idea.

Great idea, and the answer i would come up withisto somehow connect it to your sewer cleanout next to the outsde of your house. That way it will vent throuth the cities serwer system and vent up a man hole cover somewhere. Shouldnot go back through the house because there is P traps tht block it.

if your shoving air up a vent how is air going to get down the vent to vent the fixture?

the air will follow the easiest path . if no venting is needed then it would more than likely go up the vent and ouside , if the vent is suddenly needed ( like flushing the toilet ) then the air will divert down and be used to keep the traps from sucking dry ( one of the main purposes for vents ) to be honest the extra pressure from the exhaust air would prolly be benificial .

[QUOTE=Potzilla;3498928]keep in mind that theirs a big difference between what should have been done and whats the right way that things should be done and what people do. just because something is "supposed to be that way" dosent always mean it is. all im saying is make sure you double check..

thats relay why theres vets? methane?!? it goes boom?? being a plumber i did not know that.

heres a list of some of the places i have found vents exsiting

inside walls
in attics
inside cabnits
into dryer ducting
into electrical boxes
into a capped line

i could go on forever, and i could give you pics of some of these i always get a kick out of what ppl will do in order to be cheap.

yes mate i see them too every now and then, but they are very few and far between.
