Okay so back to my basement reno project, id like to add a new floor drain beside my water heater and HVAC, for the condensation drain and overflow pipe to dump into...
It's about a 20-25 foot run to where I could tie it into my 3" stubout which will be for a toilet drain.
I assume it's gonna need venting so the toilet flush doesn't pull from the trap? The floor drain being in the middle of the floor can't really be vented near its trap. Can I vent it right before it connects to the toilet drain arm?
Also floor drain should be 2" all the way from the inlet til it joins the 3" branch right?
I have one final question on this I'll post in another thread once you guys confirm how the vent should be run thanks.

Does the floor drain have to go to the septic ? The inspectors in my area make us run basement floor drains to sunlight, meaning just outside the foundation somewhere.

Hmm the existing floor drain connects to the city sewer line. Daylighting is impossible because of the lay of the land. Without a pump anyway.

You can roll a wye up on a 45 and run a dry horizontal vent under the slab. The vent suppose to turn up in the nearest available wall.
