sewage ejector venting
I'm planning to install a sewage ejector in the basement for a shower, toilet and sink. In general, routing the vent pipes will be a challenge. I have a couple of questions:
1. Any issues with running a vent outside the house from the basement, then up the side of the house, through the eaves, through the roof? This will be much easier than running the vent through the interior of the house.
2. Can the vent for the basement fixtures (toilet, shower, etc.) share the vent with the ejector? Or does the ejector required a dedicated vent? I'm hoping to use just one vent stack for everything.
3. Any advice/experience on sewage ejectors? I'm looking at the LittleGiant 9S-SMPX series.
Thanks.

1. The volume of air from the atmosphere that is needed in a rapid draw-down and
2. They do not want a clog to cause drainage from another fixture inadvertently going into the sewage ejector pit on a higher level that normally wouldn't enter the system.
Avoiding overload and cycling of waste matter through the system if it has no way to remove the contents.
Sounds confusing but it is important that it is separate through the roof.

one last question in this thread...
since the toilet, sink and shower all will share the same drain line to the sump, is it a good idea to install (not sure what the right name is) a check valve in the shower drain? so evaporation of water in the shower trap or a backup will not flow into the lowest escape point, the shower?

Not required...........especially if the shower is used enough to where the trap reservoir stays plentiful.
Couldn't find a diagram that shows VTR in my code book; the masters test I took though had that on there with individual VTR.
Residential is 2"
Commercial is 3"
Must increase to 3" on 2" residential 18" before entering roof line.
