I'm looking for a simple straight forward answer to the following scenario based on National Standard Plumbing Code 2015 (NJ).
I plan on installing a basement bathroom with only a toilet and sink (no shower).
The toilet and sink will drain into an ejector pit.
The ejector pit is currently vented to the roof through a 1.5" vent (works fine, installed by licensed plumber, passed inspection).
As far as venting is concerned, what do I need vent wise for the toilet and sink? I've identified several possible options:
Option A: Tie into the same 1.5" vent that the ejector pit is on (although it's absolute minimum, I am of the belief that it meets code)
Option B: Increase the size of the ejector pit vent, then tie in. (probably the best way to go, but hate the idea of altering the roof penetration)
Option C: Tie in to the 3" vent on the other end of the house (would require about 40ft horizontal pipe and about 15ft vertical pipe to do so)
Option D: Run a new vent pipe to the roof (not possible without a significant amount of labor and minimum 10ft horizontal run).
Can I tie them into the same vent as the ejector pit? Would increasing the size of the vent to 2" or 3" change this answer?
If I cannot tie in to the vent that the ejector pit is on, what is the maximum length of pipe (both horizontal and vertical) that I can use to tie into the 3" main stack? What diameter pipe do I need to do this, if this is the way I am going?
