Guys, what size pipe does this kind of toilet system need to connect/discharge into? I only have a kitchen drainpipe in my basement ceiling that I can tap into, but its only 1 1/4. The stack is not in the basement believe it or not, its in the kitchen wall and ties into teh septic tank outside, so I can't get to it.

The sewer line that comes up to the toilet bowl is 3" or 4". You can use either size. Home Depot sells a floor flange that comes from either size that bolts to the bowl. You would probably need to add a sewage pump to pump the drainage up to the 1st floor.
Sorry this is wrong. I was not sure what a macerating pump was until now. I looked it up.

You guys mean a discharge line as small as 3/4 can be used?

Yep, looks like it can discharge through a 3/4" pipe.

My next question for you guys is: does any kind of venting need to be done for this. I will probably also install a sink too and have the macerator pump it out.

I'm a plumber in Philly. I just put a mascerating system in last week. It calls for a 3/4 discharge. If you go to the website, i think it's sanipro.com, you can download the paperwork that tells you all the specs. They tell you to use long radius elbows and it's best to go up to a highpoint and then from there pitch the pipe down towards your tie-in point. Don't run the discharge on a 45 degree angle either. They also don't want you to use soft tubing (i.e. flexible pipe). I always run the discharge in 3/4 copper, and then the wastelines and vent in 1.5" pvc. If you need any more advice let me know. Good luck!
