I want a small sink in my basement bar area. The main drain for the house runs along the basement ceiling so I need a pump. I want to use an undersink ejector. I need to run the rough-in for a drain and vent.

The drain will go up above the main drain line and connect as it should.

My question is the vent. Can I run a 2" pipe up through the wall, then horizontal over and connect into the bathroom vent? The length of this run would be about 15 feet. I had heard there may be rules against this.

Yes, Zoller pumps have a pump kit with all you need to install this in the bsement. it can stand alon or recessed in the ground.

Our ejector pump is malfunctioning and the waste water just backed up into our sink full of dirty dishes. I would just like to know the best way to clean this mess up, because on the side of the bleach bottle it says not to use on surfaces meant for eating. Help! I'm stuck in a shitty situation..

NO!

A sewage ejector pump crock vent is required to vent through the roof. It may not be connected to any other vent in the house DWV system.
