Sump Pit issues?

I am new so be gentle...however, I am having my basement finished and about 3 days away from carpet install. I noticed a few weeks ago that my sump pump had not been going off when it was raining. So, I jiggled the discharge pipe and it turned on. so, we had it replaced. got a new 1/2 horse zoller and it works. However, had some rain (first rain in a while) and the new sump pump never went off. The guys that are finishing the basement had been down there the two days it rained. Of course, it could have gone off and with all the noise...they just never heard it.

So, my OCD kicked in and i got the hose from outside the house. and ran it through the window in the basement. The sump is sealed for radon, but I was able to get the rubber grommet that holds the electical line to plug in and that created a big enough hole for me to see down in and also run water. I ran the water in the sump pit for 25 minutes. Here is my issue. The sump pit never filled up with water. WHERE DID THE WATER GO and is that a good thing or a bad thing that the water never filled up in the pit? My house is 4 years old and we have never had a drop of water in the basement. So, again - the OCD - dont want any, but not sure when the pit will fill up naturaly with outside water to go off on its own if I can stick a hose in there for 25 minutes with no result!

Not sure how a radon a floor is isolated. But in a normal basement, perimeter drains run to the sump pit which is then pumped by the pump. If those drain points are higher than the pump, the pit should fill up to those hoses and then begin to fill the hoses. If the drain hoses are low in the pit, the water you are filling could be flowing back into those hoses. Does that make sense. But the pump should still work once the trip point is reached.

Yup, Bill has it
I have 3 pipes (maybe 4) that go under my basement floor
Water drains from these pipes to the sump pit
Once the pipes fill & the sump pump fills to a certain point then the sump pump goes on
I have regraded the ground around my house
Extended downspouts away from the house, ran 2 drain lines 25' away
Gutters on an addition have further directed water away from the house
This past Spring, despite the wettest weather ver my pump never went on

The pipes most likely are perforated, you would need to saturate the ground under your house before you could fill up that pit
That could take days...or never happen with a garden hose
