Not sure how often a sump should cycle. I have a battery backup installed in case of a failure and it has adequate flow to keep up. The pump runs for 10-15 seconds about every minute after a rain. In the picture you can see how much water is flowing in to the pit id say the rate is equivalent to a sink facuet at 1/2 to 3/4 open. 

I did replace the check valve as i read that could cause it but the water isnt coming back in from the discharge pipe.

Is this to frequent? Where should i start looking?
