When I dig into the slab is water going to come up?

House was built in 2014.

Already have 2 sump pits, 4 sump pumps and Generac.
Because I need to have access to the sump pumps.
The details I have read about show the sump pits covered and sealed so the radon fan can pull a negative pressure below the slab. If the pit and system are installed at the same time they have lids specifically for that.
My sump pits have channels that goes to the perimeter channel.

So you wouldn't be able to get a seal anyway.

Was the plumbing for your radon system installed when the house was built?
Haven't checked in the attic yet. I don't want to pump radon internally through the house anyway.
Then my Googling must be weak.

Please link to info.
