Bilge pump running when at slip, worried about it draining battery and why?

I have a Cobalt CS23 Surf.
It's brand new and I tied it off on my slip Thursday and when I came back Saturday the bilge pump had been running quite a bit.
When I checked the center hull storage where the central ballast tank is at there was a fair amount of water there.
The ballast tanks were emptied when I docked so it wasn't that it was leaking from a full ballast.
It must have been running rather regularly as the whole side of the boat was covered in spray from it bouncing off the dock.
How often should the bilge pump run if a boat is sitting idle in still zero wake water?
I don't understand how was taking on water at all.
