Basement bathroom - how to vent?

[garrett1812]

I am in the planning stages of finishing a basement in a house built in 2015, which already has roughed in plumbing for a bathroom (from left to right: shower(under black cap), toilet, vanity). However, I do not see anywhere to connect to a vent in this area. I would prefer not to mess with the two finished levels above the basement.

The bathroom rough in feeds to an ejector pit, which appears to have a vent. The ejector pit is on the other side of the basement (maybe 40ft away?). Can I tie the bathroom vent into this vent?

Also, it looks easy to vent the sink, but not the toilet or shower. Can these share the vent with the sink? I really would like to avoid opening concrete?

Thanks!

Start with your first picture then take a series of pictures from there to the point of where your vent goes up through the floor.
no one can tell how to do the venting with just those two pictures.

The lav run with 2" as waste and vent is working as the venting for the tub and toilet. Throw a 2x1.5" santee on it to pick up the lav.
Then you have to figure out where that 2" vent is tying in.

The first four pictures attached are from the bathroom area, looking up as suggested. First by the radon vent and water meter, and the next three above the shower, toilet, and sink pipes, in that order. I don’t see anywhere to tie in to a vent. The fifth picture is what looks like the vent from the ejector pit going up somewhere.

Probably best answered by your plumbing inspector. Size of vent, gpm of pump, and length are factors to be considered.

The layout of the walls in the house determines how best to run a new vent. Vents can often be tied together on floors above or in an attic space, and they can of course always terminate through the roof.
