I have 2" vent in my house that drains almost to main drain pipe very low in basement and goes to the roof through 2 floors. Currently several fixtures on first floor bathroom and kitchen sink (also from first floor) are not vented at all. There are two vents going through the roof: main stack vent and this 2" vent. I installed sewage ejector in my basement and want to vent it through 2" vent, I also want to vent through this vent all other first floor fixtures that are not vented now. Can I do this? I know that individual vents must connect to main stack vent at least 6" above highest fixture flood level. Does this requirement apply to my 2" vent? It is only vent, nothing drains to it. I also don't know if any fixture from second floor bathroom is vented through it.
