Replacing vent stack question

Hi- I will be replacing my old iron stack with new pvc. This is one stage of many in this project. My question is can I remove the old stack and then leave the opening in the basement as a temporary vent(no stack rise) for a few weeks while I finish the other parts. Will my plumbing system function OK for a while or do I need to hook it back up the same day before I use any fixtures. I prefer to be able to take my time and it will take me some time for the other things I am doing such as relocating and replacing the main drain. I do have this all approved and permitted for my location. Inspection here is so lax as to be basically non-existent. This is a simple 2 bedroom 1 bath single story home hooked up to a city system. Thanks for any advice

Hello and welcome...

Sewer gas is deadly... You can get sick and/or death can occur... I would not leave a main stack open in a home period......

At best get a studor vent with a high DFU capacity and install.... Or complete the job....

Totally agree with Mike. Always keep the vents and stub-outs sealed when working.

I would rather just seal the vent with a temporary Fernco if it's just for a few days. You'll have to take precautions to ensure the sink and toilet traps don't get sucked-dry without a working vent.
