Hello everyone - I've learned a tremendous amount reading this thread over the past few months as we've been designing and starting a basement remodel (teenager needs a mancave!)
It's a big project, with many moving parts - not least the plumbing. Our situation: 105 year old house in Seattle, main sewer exit is in basement through the wall about an inch above the floor.
Therefore need an ejector. Plan is for installation of bathroom - toilet, lav and shower, as well as a laundry, and next to this a small kitchen with a sink but no dishwasher or garbage disposal.
I've attached a (rather ineptly) drawn plan, done in powerpoint - hope it's clear. Blue are drains, yellow are vents, brown is effluent from ejector to main sewer. It enters the stack about 20" above the floor, into a new (to be built) 2' branch line cut into the 4" main stack with a santee.
