Exhausting into sewage pipe?

Look on the roof of your house for a vent tube, locate where it comes through inside. and tap into it as close as you can where it goes through the roof if you can. It will work and won't blow out anyones toilet....
This may be a stupid question but is there any way that exhausting through the top vent would make my other toilets around the house not flush properly or slower them normal?

Rocketman, no....the vent is designed to take pressure off the septic... asw shit rots it builds gasses and it needs to go somewhere. thats why the vents are there qand why the arre locacated near most all the devises. this tupe, stink pipe, chimney, what e3ver you want to call it, should come direc6tly from the sewe3r4, straight out through the home(connecting all sink, toiltletrys) and eaxhaust them right thought the roof.... tap into that pipe brforwe it goes through the roof, and you'll be good to go...
 
What up rocketkush! There is an easier way to vent into the sewer line, especially if youre in the basement! If you look at some of the piping in your basement, it might be close to the toilet or maybe the water heater, there's usually a cap that you can screw off. The cap is round and has a raised square on it that I think is used to help loosen it. If you can imagine the lid of a jar with a dice (or some other kind of cube) placed in the middle of it, thats what this looks like.... Im sure somebody knows what im talkin about! Anyway that actually goes directly to the sewer line and you can vent all the yummy stinkyness you want down this hole with no issues whatsover!
I just remembered where I saw this and it wouldve been way easier to just post a link but oh well! Everybody knows the old OVERGROW.COM FAQS page right? Its still all over the web just google it. But somewhere in there (the venting section maybe) there's a whole page on how to do this properly and from what Ive heard this is one of the most secure and effective methods of odor removal.
I think this would be alot easier and less problematic than the toilet pipe if youve got access to one of these pipes and most houses do.
If you have any trouble finding this lemme know and Ill hunt down the link for ya dog
PEACE

Are you planing on piping into the vent pipe or septic/sewer pipe? I think venting into the vent pipe should be fine. The only thing I can think of is the size of a vent line 1-1/2" to 2" vent pipe is not that large for good air volume. If trying to vent into the septic/sewer line directly I see possibly a surge of dirty water and the air before it rushing down and slightly pressurizing your vent line to your grow room. I'm not a plumber. I'd try it if using the vent line only, if I had it available close to my room. Let us know what you do.

I am concerned about the Toilet being lower than ground level
he did say it was in a basement so there should be a sump pump
pumping it up to the drain field and septic tank this may not have a vent.
in order for a normal toilet to work it will need a vent to the roof, so that water can go down.
...so in the wall behind the toilet there should be a 2" to 4" pvc pipe vent to the roof
this will go down and connect to a "T" about 12" to 24" past the hole in the floor
any bathrooms/sinks above the missing toilet will share this vent but I see no unforeseen explosions....
I do like the smoke bomb test it would show you where the gass will come out
(hopefully not in your neighbors house)

For a start off sewer gases are never vented into a loft space, for the same reason they vent them out of the sewer,
methane gas explosion's
he has already stated the toilet can be removed so acsess is not a problem
as said before sewer gases are never vented where there easily smealt
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.

ever stuck your straw in your glass and put ur finger over it? awesome how the water stays in the straw even after you take it out of the water.. vents let air in behind water so it will actually go down the pipe in somewhat of a fast mannor.. i could go on for days about vents.. in anycase if you want to do this and it still dosent sound like a headach and BS having to deal with cfm loss my advice would be to tie into the VENT LINE not the drain line.


happy growing!

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.

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 .

Whats up soil king, that pipe in your house im talking about is actually a direct line to the sewer system. The smelly air is gonna go straight into the city sewer system and out a manhole somewhere after its already disipated. Check out the link in my first post, its from the old overgrow archives and tells you all about how ta do this with pics.
