Did I Mess Up My OAK?

I've been thinking more about this and you're absolutely right about the boiling.
It has to have been water that made sounds in another way.

But my main point is that you don't need air volume/air flow thru the fan. Just an under pressure created under the slab, and the radon will flow to the fan and out.

If you have a sump pump connected to the foundation will it comeup there? And can you add a blower to the sump pump hole? My basement is mostly finished so if I get high readings I'm not sure what to do. Maybe the only high reading will be in the laundry room where the sump pump is. There could be many floor cracks but I can't see them. I do see one in my furnace room. Anyway, I don't have my meter yet.

I think so yes. If it collects under your slab, it'll come up via the easiest path.
And a dump pump has (microscopic) pathways towards it where the water flows to the pump, enabling the radon to go as well.

Yes there are covers made for radon fans connected to sump pits. They form airtight seals to the sump pit.
