Sewage ejector basement bathroom venting

[Rmichael]

Hi I’m putting a bathroom in a basement using a sewage pit/pump. Just wanted to make sure my vent plan looks ok. Is the shower ok wet vented through the lav?

I changed the drawing. The lav can vent the entire bathroom if the piping for that is run in 2".
The vent for the pump and bathroom can tie back in above the flood level of the highest fixture. That means if there is plumbing on the next floor, the vent goes 42" above that floor before it can tie back in. You can't tie a vent into a waste line.

The pump gets a check valve and a shutoff above that.

Thanks so much for the quick reply! Was planning on tying into the stack in the attic to avoid another roof penetration.
