should I vent into sewers

[clide]

Okay, I tried this and the pipe I was venting into was in the basement and about 100 feet from the main sewer pipe (it was a clean out trap that was not in the main line of poop flow). I was also venting above the main sewer pipe, up on a hill. I had a 6 inch vortex fan. This lasted about 1 day. Not because of any gases because I could not smell a thing. What happened is that the forced air created a vacuum and was slowly sucking the water out of the piss-pots. I would not do it.

Here in town recently there was a grow-op busted in a store front basement on a main street. It was brought to LEO's attention because city workers in the drain sewer reported an overwhelming smell of marijuanna when carrying on with their regular everyday duties. They traced it right back to it's source and then got a warrant. Hundreds of plants were destroyed and even the owners admitted to thinking it was a fool proof plan.

I have tried venting down a sewer drain in a basement before and it worked great and my plummer friend who has been in the business for years stated it would cause no problems health wise, at least with the way my drain is set up. I can't say forsure if this pertains to all sewer drains.

So I believe it can be done in some situations as long as it ends up joning to a rain sewer. You will still have to worry where that smell is going and who is smelling it. Personally I think all venting should be carbon scrubbed first, then think about venting down a sewer later. Better safe than sorry.

so what you guys are saying is:
a)use a carbon filter in front of the fan
b)use a variac to dial in the amount of air pressure the fan is applying to the drain
c)have a 2nd Y attached before hand
d)use a back draft damper to ensure no nasty gases

and under those conditions it would be ok to vent into the sewer?

If you have the carbon scrubber why not vent somewhere else? My opinion is that it is a very bad idea, for the already mentioned p and s traps that will not function properly. Also seems as if it would create tons of backpressure making grow room air exchange a fraction of what it would be.
