I believe that is why we probably still had water int he basement because it is not pumping as frequently as it should. Also, is it normal for the pit to be filled with water?
The reason why your pit is still full of water is probably because your drain tile is full of water too, and it's equalized in your pit. The drain tile works to route water from your foundation to the pit. If water is not pumped out of the pit, the drain tile will continue to fill up with water.
Your sump pump is designed to run about 25 seconds once the float is initiated. That 25 seconds doesn't seem to be enough time for you to clear out all the water in your pit and tile.
What you need to do is to look at the sump cord plug. There are usually two plugs on the end that are plugged together. Pull apart the plug and plug the backplug into the outlet. This will cause the pump to run continuously until you disconnect it. Keep the pump running until all the water is gone.
Also, for the most part, floats are not to be adjusted on sump pumps. In your case though, it seems that the initiation position of your float doesn't kick in early enough possibly because the pit is not deep enough. You may need to adjust it, or buy a pump that has a vertical float switch. These usually kick off sooner.
Also, make sure your piping has a check valve to keep most of the water from returning.
