Vent pipe or backup sump pump drain line?

[Tim H15]

hi
I want to create a sealed cover for my sump pump pit to keep gases out.
So, I read if you are going to seal your sump pump cover, you should have a vent pipe/line. (I do have vent HOLE drilled in pipe)
I have 2 pvc pipes running from my pit
1 -main pump connects to pvc line with check valve which runs / drains very far from the house.
2 - backup sump pump connects to pvc line with check valve and terminates just as the pvc pipe exits the side of the house.
We bought the house 7 months ago and home inspector did not have anything critical to say here

Is #2 pipe the vent line?
Is this setup as described ok for a sealed sump pit cover?
Thank you

Is #2 pipe the vent line?

No. It is the output of the second pump. Why did the person not combine the two pump outputs with 2 check valves? Maybe he wanted to see the output if the second pump operated so he would know to fix pump #1. Maybe he wanted to have a separate path in case the drain for the main pump clogged.

Is this setup as described ok for a sealed sump pit cover?

Did you think you posted a photo? Regular sealed pits are OK for toilet waste, and the cover should have a 2 inch vent pipe to the vent system that goes out the roof. Those pits have gaskets for the cover.

If you are adding a vent for a system that is not required to be vented, you could do something less I expect.

Thanks for the reply. No I didn’t post a pic.
So my township says they like the way each pump is connected to a different pipe.
The true question is this- I live in a high radon area. We do have a radon system in the basement. What I have read is that if you live in a high radon area and you seal you your sump pump pit you should have a vent pipe which exits through the roof to let the gases escape. I know my sewer pit has a vent pipe that exits through the roof. But no vent for the sump
pit. Really I just want to seal this dang pit without creating problems.

It is very challenging to create an airtight cover for a sump pit that was not designed to have one in the first place. You might consider getting a radon test kit to see if you really even have a problem before you try to fix one that might not exist.
