Plumbing Code - Can I tie my bathroom exaust fan into the main plumbing vent to the outside.

Precisely. That's *exactly* what the trap is for. Many people believe, mistakenly, that the trap is there to catch objects and stop them from going down the drain. Nope. It's there for one reason: to keep sewer gas from coming

*up*. And that's why it's important for there to be water in the trap all the time.

How many times do you need to be told it's not a good idea, before that finally sinks in?

He was waiting for YOU to stop by and tell him. He didn't believe anyone else.

You really should see a therapist, Joe. This fixation you have on me isn't healthy.

My fixation? 4-5 hours ago, half a dozen people told him his idea was lame. You needed to chime in and say the exact same thing?

I see you're still having trouble with reading comprehension -- I responded to his question about the trap.

I see you have a long thread about this, but I didn't see one of the simplest answers. The sewer stack isn't big enough. The vent fan needs a 4 inch line. For a sewer vent plus a fan vent you need a 6 to 8 inch line. I doubt if you have a sewer stack that large.

The proper way is to run the vent fan in a 4 inch metal vent pipe to its own outside vent.

: I would not tie in to your bathroom air vent. You need to run a new vent up through the room.

Yet another useless response from the succo company that adds nothing to the answer provided by trader (an probably numerous other people) in a 3 year old thread with the OP long gone.

The succo company response is spam from a plumber. With a response this stupid it is a company for anyone in Louisiana to avoid.
