Sewage ejector vent into radon abatement system?

Asked Apr 15, 2012, 03:29 AM — 3 Answers
We are installing a new full bathroom (toilet, shower, sink) in a basement, but venting the sewage ejector system near the bathroom would result in it exiting out the front of my home. Obviously I do not want effluent odor venting to the front of my home near my front door. I have a fully operational radon abatement system that is about eight feet from the placement of the sewage ejector system. Is it allowable to vent into that pipe since it is being vented above the roof line?
Thanks Rick

A sewage ejector system has two separate vents. The fixture vent that vents like any ordinary vent and then we have the pit vent which is a dedicated vent This means that this vent can not tie back to any other vent or venting system. The exception to this, as I understand it. is the new Sanaflush system that may revented back to the house system the same as a fixture vent. What system are you installing. Back to you, Tom

I am installing a zoeller sewage ejector pump in a 24 x30 basin mounted in the floor.
We could not use the saniflush system due to the ceiling height. It would have caused us to elevate the shower by 6".

Then the pit vent CAN NOT tie back to another vent. It MUST be a dedicated vent. The fixture vent, however, can be run to the attic and revented back to a existing roof vent or if mechanical vents are allowed you may vent the fixtures with a AAV. Good luck, Tom
