Fixture venting question

I'm planning a below-grade bathroom with a sewage ejector pump, toilet, sink, and shower. I understand the sewage ejector needs its own vent.

Can I tie the fixtures to a single vent? What about to an existing vent?

I'll likely have a professional do the work, but I like to be armed with a little knowledge.


Re: Fixture venting question

Your fixtures and the ejector can connect to the same vent. They can also connect to a existing vent as long as it's connected 6" above the flood rim of the highest fixture.

Thank you!

Re: Fixture venting question

That also make auto vent's or some people call them scooter vents or mechanical vent's that also can be used long as they are exposed and not buried in a wall without access.

auto vents are not code in every state.
