I have been living in my current house for 9 months and our sump pump runs constantly even when there is a drought. Over the summer we did not have rain for 2 months and it would still run every 5-10 minutes. When it does rain it will run every 10 seconds for weeks and then 20-30 seconds for weeks etc. But when it does rain no water comes from the drain tile pipe. It all comes from the side of the pit. The pit has holes in it and water comes from the holes and what appears to be from bottom of the pit. We have a back up pump that runs off water pressure and an alarm to notify when pumps may fail. My question is do I in fact have a "high water table" or is something wrong with my pit? Thank you in advance for any recommendations.

It is working as designed but you can look at how deep in the pit you are trying to keep the level at. There is no problem with having water 4 or 5 inches below the bottom of the slab. The problem with setting it that high, when you get lots of water, will the pump b able to keep up.
Have you done all the regular home work, slopes and downspouts away from house. The destination of the water you are pumping.
Yes, all downspouts are pushing water away from the house and our house has downhill slopes coming off the foundation. I have not tried to see how high it will get before it may stop.

New houses that get a perimeter drain on the outside the pipe is laid beside the footing so it might be as much as 8" below the slab, when the drain works we never have a problem.
House was built in 2007. So are you saying the water can sit in the drain 8 inches below the slab and be okay?

In most houses that is where the drain pipe would be so if water was just below that we would never know.
You have holes in the bottom of the sump to let ground water in so the pit does not float. but the drain i the level of the pipe coming in so water below the pipe is fine.
As long as you can set the float so the water level can be kept between the bottom of the pipe and a couple inches below the bottom of the slab. You might have to keep it a little lower than the pipe,but you don't have to pump the ground water for the whole neighbourhood which is below.
They always put the submersible pumps at the bottom of the pit. And my question is would that be the same if some one put the pit 8 ft deep.
But if you change anything you will want to monitor it during that down pour.
