Sewage Ejector Pit - Vent tie in

[awall2424]

I built my home last year and had left the basement unfinished. I did the under slab plumbing myself - typical bathroom - shower, toilet with a 2” wet vent that will catch the vanity sink - tied in to an ejector pit. I had a plumber do the rest of the house, but he capped the basement vents at the joists as well as the ejector discharge and 2” ejector vent. I am finishing that bathroom and now realize the bath vent he dropped and capped is 1 1/2” and should have been 2”. My question, the ejector is about 8’ from the toilet, can that function as a vent? I assume no. My other option is tie my 2” vent coming from below slab into the ejector pit 2” vent going up through the roof, and use the 1 1/2” drop for my vanity sink. I’m in Ohio. I couldn’t find a definitive answer (or one that I followed) in some of the other threads. Thanks

As far as the plumbing inspector is concerned, it’s finished. I paid for the bathroom in the permit and he signed it off - small county health dept. It’s also a 4” line, which I believe helps. That’s why I was curious if the ejector pit can be used as a vent, but I don’t believe it can be.

I had misunderstood your question.

As long as you tie the vents together above the flood rim of any fixtures, this would be a good choice (if I understand the layout).
When the pump kicks on, it wants to be running with no air resistance, even if all the drains are flowing full-on.

It would tie in about 3’ above the flood rim of the basement fixtures only - so just the fixtures it is serving. The 2” ejector vent ties in near the roof line, where the 3” penetrates the roof.

What you are suggesting is what I assume is the best option, I just don’t want to have issues down the road.
