Hi, I just installed a sewage punm & basement bathroom. I had the pit installed when I built 7 years ago, and finally got to the projet...Anyway, My contactor dropped a vent down from the basement ceiling for me to hook into. I believe it is the same one that goes throught the roof. I am now getting some odor in the basement. I hooked into the main sewer line above the ejector pit & I ran to the vent stack I mentioned.
Any idea why I may be getting teh odor?
Did you put the rubber gasket between the lid and the basin? May not be a bad idea to run a bead of silicone around the penetraions on lid and smear it in with your finger to ensure no smell escapes. Also check and make sure the fixture traps connected to pump are full of water.

Does the holding tank itself have a connection to the vent?
Check all components and joints to be sure everything is sealed and there are no cracks.
Less than perfect installation of the toilet, particularly the wax ring underneath, is more likely to give odors with a lift system compared with a straight drain connection for a toilet upstairs.
A lift system using a pit you dug or poured yourself is more likely to give odor problems compared with a system that comes with a plastic tank. This is because it is more difficult to seal the lid onto your own concrete lined pit.
Tornado victims: Do not rush to rebuild. Take your time and look for and get a good contractor. Or consider selling the property and moving to a home that is ready to live in.
