Water seeping into sump pit BELOW the drain pipe?

I was looking at my sump pump earlier as it was running frequently (we've had a lot of snow/rain in the past couple of days) to make sure everything was ok. I noticed that I had a steady stream of water trickling down the side of the sump pit just below the drain pipe. I felt along the underside of the pipe and noticed a small crevice between the pipe and the egde of the hole. Now, everything seems to operating ok - water is collecting into my sump pit, and the pump is pumping it out. But I didn't know if this was ok to have most of the drain water coming from a crevice below the pipe as opposed to the pipe itself. It doesn't seem like the crevice is a torn or cracked section; it just feels like the pipe isn't quite large enough to fill up the pipe on that underside (it's a small crevice, not very large).

Is this a big problem that warrants a plumper's call, or should it be fine as-is? I'm also wondering if more water is coming into my pit that should be with it like this, or if the same amount water would just come out the pipe instead if the crevice was completely closed off. Here's a drawn picture that shows what I'm referring to: pic

 

It would appear that you are getting ground water due to the amount of rain and snow. As long as the sump pump is getting rid of the amount, I would not worry. You could probably patch the problem area with hydraulic cement but this may cause the water to go somewhere else where it could be a problem. Good luck.
