The last connection at the end of this main sewer line is the vent that goes vertical up to the roof. I would like to install a laundry tray pump below and discharge it up at some point into this line. I'm having difficulty trying to figure out how to vent the unit since access to the vertical vent is not possible without major impacts. Can I come up off the end of this line with a vent back to the pump unit? If not, any ideas how I could vent the unit without major work?
